     BACKGROUND 
       [0002]    A television remote control and some portable electronic devices, such as a cell phone, are difficult to use for text-based searching with current text input methods, particularly due to the limited set of input keys available on such devices. For example, other than the various configuration and television-specific input keys, a television remote control only has a standard numeric input keypad that includes the numbers zero through nine to input a channel selection. A viewer cannot easily input letters for a text search in an electronic program guide to search for a specific program, music, television content, or various other applications that may be available via the viewer&#39;s cable provider or other television system content provider. Further, conventional text searching techniques require that a user-entered search term be spelled correctly to locate the desired term. 
         [0003]    Other electronic devices, such as a cell phone for example, are typically equipped with a conventional alphanumeric input keypad that includes the numbers zero through nine along with the alphabetic characters “A” to “Z”. Although zero (0) through nine (9) is a total of ten input keys, an alphanumeric or numeric input keypad is commonly referred to as a “9-key” keypad. The letters on a “9-key” keypad are distributed along with the numbers two (2) through nine (9). For example, the number two (2) includes the letters “A”, “B”, and “C”, the number three (3) includes the letters “D”, “E”, and “F”, and so on with each consecutive number being associated with the next consecutive three letters. The letters “Q” and “Z” may not be included on some keypads, but if they are, the number seven (7) has four associated letters to include “Q” and the number nine (9) has four associated letters to include “Z”. 
         [0004]    There are techniques available to enter text with an alphanumeric “9-key” keypad, however they are cumbersome and in some cases, can require more user inputs than would actually be required to input a text string for the word itself, such as with a computer keyboard. For example, multi-tapping (also referred to as triple tap) is a technique to enter text and/or letters with a “9-key” keypad, such as with a cell phone to create a text message. As described above, the letters “A”, “B”, and “C” are associated with the number two (2) input key on the keypad. Pressing the input key once enters an “A”, twice enters a “B”, three times enters a “C”, and four times enters a “4”. Spelling out even short words for a text input can require multiple key entries. For example, to spell out “CAB”, a user would have to press the number two (2) input key a total of six times—three more inputs than would even be necessary with a conventional keyboard. 
         [0005]    An alternative text-entry technique is “T9” (“text on nine keys”) which selects a letter that is associated with a key input to spell a word correctly based on a likelihood of letter combinations. With “T9”, a user may only have to press an input key once rather than multiple times as with multi-tapping. For example, to again spell out “CAB”, a user would only have to press the number two (2) input key a total of three times (once for “C”, twice for “CC”, and a third time for “CAB”). The “T9” technique is not without its limitations however. Depending on the presumed likely letter combinations, a user may have to switch back to multi-tapping to create a word that “T9” does not recognize, or the user may have to input several “T9” key combinations to create the word. 
         [0006]    Irrespective of the technique implemented to enter text with an alphanumeric “9-key” keypad, the conventional text input techniques are cumbersome, often require more key inputs than would otherwise be necessary, and/or require unnatural combinations of key inputs. 
       SUMMARY 
       [0007]    Gesture based character input is described herein. 
         [0008]    In an embodiment of gesture based character input, a character shape is input on a keypad device, via selection of a sequence of keys. The character is determined based upon the shape of the character as represented by the selected sequence of keys. Characters derived from multiple key sequences are assembled to create character strings. 
         [0009]    In an embodiment each character in a string of characters is represented by a numeric equivalent of the character.

     DETAILED DESCRIPTION  
       [0020]    Predictive phonetic data search is described in which embodiments provide for improved text searching techniques with a restrictive input device, such as a television remote control, cell phone, or other similar devices that have a conventional “9-key” numeric or alphanumeric input keypad. A user can input a search request to locate a term, such as a particular television program, music channel, network-based application, and the like, where a search “term” can be any form of text, letters, a word, a group of words, and/or any combination of characters and numbers. A numeric index includes a number that matches a numerical equivalent of the term designated in the search request. The numeric index also includes numerical equivalent(s) that correspond to translations of the term and phonetic equivalents of the term so that the term designated in the search request does not have to be spelled correctly when input to locate the search term. 
         [0021]    When a numeric equivalent that corresponds to the search term is located in the numeric index, the search term can be obtained from a term index that is mapped to the numeric equivalent(s) which correspond to the search term and/or translations and phonetic equivalents of the search term. The search term can then be returned in response to the search request. For example, the requested search term may be displayed in an electronic program guide on a television that also displays programming information corresponding to the search term, such as for a particular television program. By pre-computing a numeric equivalent for the search term and for the possible translations and/or phonetic equivalents of the search term, the search-and-match process can be executed faster than conventional text-based searching to match the actual characters of a search term. 
         [0022]    The terms that are maintained in the term index, and from which the numeric equivalents are determined, are received and identified from any number of text data sources, such as electronic program guide data and/or closed captions data corresponding to television content. The numeric equivalents of each term, the translations of the term, and/or the phonetic equivalents of the term are computed and maintained in the numeric index which can be searched for a requested search term. Each numeric equivalent in the numeric index is mapped to the corresponding search term in the term index such that when a numeric equivalent of the particular search term is located in the numeric index, the corresponding search term in the term index can be returned in response to a search request. This provides that a user need only enter a phonetic equivalent of a term that can be misspelled or does not include all of the letters and/or numbers of the term to minimize the number of keypad inputs, yet still receive a correct response to the search request. Further, the user can enter the search term in one language and receive a response to the search request in another language. 
         [0023]    While aspects of the described systems and methods for predictive phonetic data search can be implemented in any number of different computing systems, environments, television-based entertainment systems, and/or configurations, embodiments of predictive phonetic data search are described in the context of the following exemplary system architectures. 
         [0024]      FIG. 1  illustrates an exemplary data search system  100  in which embodiments of predictive phonetic data search can be implemented. In this example, the system  100  includes text data sources  102 ( 1 -N), a term manager  104 , and database server(s)  106 . In this example, the text data sources  102 ( 1 - 1 V) include electronic program guide data  102 ( 1 ), closed captions data  102 ( 2 ), and/or any text data from various sources  102 (N). The text data sources  102 ( 1 -N) may also include purchased metadata and/or data that has been edited or translated by hired personnel. In a television-based environment, the system  100  also includes encoding server(s)  108  and a content distribution system  110 . The encoding server(s)  108  can be implemented to receive and process the text data received from the text data sources  102 ( 1 -N) for distribution to client devices via the content distribution system  106 . An exemplary television-based system  900  that includes client devices is described further with reference to  FIG. 9 . 
         [0025]    The term manager  104  can be implemented to receive the text data from the encoding server(s)  108  and/or directly from the various text data sources  102 ( 1 -N) themselves. The term manager  104  identifies terms in the text data that may be requested in a search and computes a numeric equivalent of each term. For example, the term manager  104  identifies the term “Seinfeld” from the popular television comedy series in either the electronic program data  102 ( 1 ) or in the closed captions data  102 ( 2 ). The term manager  104  then computes a numeric equivalent  112  of the term. 
         [0026]    On an alphanumeric keypad, an example of which is shown in  FIG. 2 , “S” is associated with the seven (7) input key, “E” is associated with the three (3) input key, “I” is associated with the four (4) input key, “N” is associated with the six (6) input key, “F” is associated with the three (3) input key, “E” is associated with the three (3) input key, “L” is associated with the five (5) input key, and “D” is associated with the three (3) input key. As such, the numeric equivalent  112  of the data text term “Seinfeld” is 73463353. It should be noted that the techniques described herein are equally applicable for terms that include capital letters, small letters, and any combination thereof. 
         [0027]    The database server(s)  106  include a terms index  114  and a numeric index  116 , which in an embodiment, are any form of computer readable media that can store and maintain data. The terms index  114  maintains the terms identified by the term manager  104  in the text data received from the text data sources  102 ( 1 - 1 V). For example, the terms index  114  includes the term “Seinfeld” which a user may search for via an electronic program guide to find and watch an episode of the television program. The numeric index  116  maintains the numeric equivalent(s)  118  of each of the data text terms maintained in the terms index  114 . For example, the numeric equivalent  112  (i.e., 73463353) of “Seinfeld” is maintained in the numeric index  116  as the first listed numeric equivalent  120 . The numeric equivalent  120  in the numeric index  116  is mapped to the corresponding term “Seinfeld” in the terms index  114  such that when a numeric equivalent of a particular search term is located in the numeric index  116 , the corresponding search term in the term index  114  can be returned in response to a search request. 
         [0028]    The term manager  104  also computes the additional numeric equivalents  118  that each correspond to a phonetic equivalent  122  of the term. The additional numeric equivalents  118  are also maintained in the numeric index  116  and are mapped to the corresponding term in the terms index  114 . The additional numeric equivalents correspond to phonetic equivalents of a particular term in the term index  114  and may be a misspelling of the term, a spelling of the term that includes only consonants and no vowels, and/or a number in place of a word in the term. 
         [0029]    For example, the first numeric equivalent  118  that is listed (i.e., 74363353) corresponds to a misspelling of the term “Seinfeld” where a user may input the search term, but misspell the word as “Sienfeld” with an “i” before the “e”. The last numeric equivalent  118  that is listed (i.e., 76353) corresponds to a spelling of the term “Seinfeld” that includes only the consonants of the word “snfld”, and none of the vowels. As such, a user can search for the television show, yet only provide a minimal input with a restrictive input device, such as a television remote control, cell phone, or other similar devices that have a conventional “9-key” numeric or alphanumeric input keypad. 
         [0030]    In another example, a user can input search terms where a number is input in place of a word in the search term. For example, a user can search for the television program “Deep Space Nine” by inputting a search for “Deep Space 9”, or as described above “DPSC9” (or by various other letter and number combinations). For another example, a user can search for the television program “Eight is Enough” by inputting a search for “8 is Enough”, or as described above “8ENUF” (or by various other letter and number combinations). It should be noted that the phonetic equivalents  122  shown in  FIG. 2  are merely illustrative, and do not need to be maintained or stored in memory, thus saving memory space. 
         [0031]    Only the numeric equivalents  118  need be maintained such that the term manager  104  can receive a search input, determine the numerical equivalent of the search input, and then locate the number in the numeric index  116  that corresponds to the numeric equivalent of the search input. For example a user may search for “Star Trek” episodes and enter six (6) keypad inputs for “STRTRK” which the term manager  104  determines to have a numerical equivalent of 787875. Rather than searching for the actual text string of “S,T,R,T,R,K”, the term manager searches the numeric index  116  for “787875”, and when the number is located, obtains “Star Trek” from the terms index  114  to which the number is mapped. 
         [0032]      FIG. 2  illustrates an exemplary data search system  200  in which embodiments of predictive phonetic data search can be implemented. The system  200  includes the database server(s)  106  shown in  FIG. 1 , and in this example, the term manager  104  is shown as a component of a database server  106  to implement the various embodiments of predictive phonetic data search described herein. The system  200  also includes an exemplary television-based client device  202  that receives program content, program guide data, advertising content, closed captions data, and the like for display on a display device  204  (e.g., a television) via a communication network  206 , such as the content distribution system  110  shown in  FIG. 1 . In an embodiment, client device  202  can be implemented with any combination of components described with reference to the exemplary electronic and/or computing device  800  shown in  FIG. 8 . Further, an exemplary television-based system  900  is described further with reference to  FIG. 9 . 
         [0033]    A user can input a search request to locate a term, such as a particular television program, music channel, network-based application, and the like with a restrictive input device, such as a television remote control  208 , a cellular phone  210 , or a PDA  212  that only has a “9-Key” alphanumeric keypad  214 . A search term can be any form of text, letters, a word, a group of words, and/or any combination of characters and numbers. For example, the user may input a search request in an electronic program guide displayed on the display device  204  via the client device  202  with the television remote control  208 . Alternatively, (although not shown) a user may input a search request to the client device  202  via the cellular phone  210  and/or the PDA  212  which may be configured to operate as a television remote control device. 
         [0034]    A user may also input a search request with the cellular phone  210  and/or the PDA  212  via a wired or wireless connection  216  that is received by the term manager  104 . The user can input the search request with the “9-Key” alphanumeric keypad  214  on the cellular phone  210  or PDA  212  and have the requested term returned for display on a display component of the cellular phone  210  or PDA  212 . For example, a user may want to search for an upcoming broadcast of a “Seinfeld” episode, and then have the associated programming information displayed via the cellular phone  210  or PDA  212  so that the user will know what time to be home to watch the television program. Although the examples described herein pertain to searching for the “title” of a program, such as “Seinfeld”, a requested search can include any terms that may be associated with a program, movie, gaming application, music, and the like. For example, a user may search for a particular actor, director, singer, or any other criteria or category of data that can be searched to locate a requested term. 
         [0035]    A user can enter a search term via a numeric or alphanumeric keypad, such as the “9-Key” alphanumeric keypad  214 , on the television remote control  208 , cellular phone  210 , or PDA  212  as any one of: a sequence of characters, a sequence of letters each associated with a channel number input key on the keypad of the television remote control  208 , as a sequence of letters each associated with a telephone number input key entered on a keypad of the cellular phone  210 , as a text-based input that includes a sequence of characters that correspond to two or more words, as a combination of alphabetic character(s) and numeric character(s), as a phonetic equivalent of the term, as the phonetic equivalent which is a misspelling of the term, as the phonetic equivalent which includes only consonants in the term and no vowels, as the phonetic equivalent that includes a number in place of a word in the term, and/or any combination thereof. This list of search term inputs is not intended to be all-inclusive, but to merely illustrate some of the possible inputs that may be used to minimize the number of keypad entries needed when searching text data with a restrictive input device. 
         [0036]    As described, a requested search term can be returned for display via an electronic program guide displayed on display device  204  (e.g., a television), or the requested search term can be displayed on a display component of the cellular phone  210  or PDA  212  Additionally, a requested search term may return multiple listings or results which can all be displayed for the requesting user. For example, a search for a program listing or television program may return several instances of upcoming scheduled broadcasts of the program. Although an on-demand movie or gaming application does not have a typical broadcast schedule, the information returned for display may include when the on-demand content will become available to order, the associated cost, and/or any other similar information. The information returned for display in response to a requested search term may also be annotated based on a popularity of the results, to identify which of the returned search terms are already designated to be recorded (for a television program, for example), and/or any other annotations associated with the information returned for display. 
         [0037]    In another embodiment of predictive phonetic data search, a user can enter a search term in one language with the “9-Key” alphanumeric keypad  214  on the cellular phone  210  or PDA  212  and have the requested term returned for display in another language. For example, a user may want to determine if the movie “Tres Amigos”, which is titled in Spanish, is available for viewing. The user may then enter a search request in English as any one of “3 Friends”, “3friends”, or “3FRNDS” (just for examples) to locate programming information associated with the movie. Optionally, a user may configure a preference such that a response to a request entered in any language is returned in a specified language, such as Spanish. For example, if an English-speaking user is traveling in Mexico, the user can enter a search term in English on the “9-Key” alphanumeric keypad  214  on the cellular phone  210  or PDA  212  and have the requested term displayed in Spanish on a display component of the cellular phone  210  or PDA  212 . 
         [0038]      FIG. 3  illustrates exemplary database components  300  that can be implemented as part of the data search systems shown in  FIGS. 1 and 2 , and which can be implemented in embodiments of predictive phonetic data search. The database components  300  include the terms index  114  and the numeric index  116  described with reference to  FIG. 1 . The database components  300  also include a term instance index  302  and a translations index  304 . 
         [0039]    In this example, the terms index  114  includes the illustrative terms “seinfeld”, “terminator”, and “garden” which may be requested in a search by a user. As described above with reference to  FIG. 1 , a term in the terms index  114  corresponds to numeric equivalents in the numeric index  116 . For example, numeric equivalents  306  include the numeric equivalent 73463353 that corresponds to the keypad inputs for the term “seinfeld”, and includes numeric equivalents of various phonetic equivalents  308  of the term “seinfeld”. The numeric equivalents  306  in the numeric index  116  are mapped to the term “seinfeld” in the terms index  114 . 
         [0040]    Similarly, the numeric equivalents  310  include the numeric equivalent 8376462867 that corresponds to the keypad inputs for the term “terminator”, and includes numeric equivalents of various phonetic equivalents  312  of the term “terminator”. The numeric equivalents  310  in the numeric index  116  are mapped to the term “terminator” in the terms index  114 . Similarly, the numeric equivalents  314  include the numeric equivalent 427336 that corresponds to the keypad inputs for the tern “garden”, and includes numeric equivalents of various phonetic equivalents  316  of the term “garden”. The numeric equivalents  314  in the numeric index  116  are mapped to the term “garden” in the terms index  114 . It should be noted that the phonetic equivalents  308 ,  312 , and  316  shown in  FIG. 3  are merely illustrative to show the derivation of the respective numeric equivalents  306 ,  310 , and  314 . 
         [0041]    The translations index  304  includes translations of the term “garden” which are mapped to the term “garden” in the terms index  114 . When a user requests a translation of the term “garden” and a numeric equivalent  314  of the search term is located in the numeric index  116 , a translation of the search term can be returned in response to the search request. For example, a user in China may enter a search request for “GRDN” on the keypad of a cellular phone or PDA (or other portable electronic device) which is a phonetic equivalent  316  that is determined to have a numerical equivalent  314  of 4736. The numerical equivalent  314  in the numeric index  116  can be mapped back to the term “garden” in the terms index  114 , and the term “garden” can be mapped to the Chinese translation aM of the term in the translations index  304 . Although translations are only shown for the term “garden” in the translations index  304  in this example, each of the terms in the terms index  114  may have translations included in the translations index  304 . 
         [0042]    The term instance index  302  includes service identifiers (i.e., a “Service_Id”) that each correspond to a term in the terms index  114 . A service identifier includes term instances that define how content associated with a term is presented for use by a user if a user selects the term from displayed results. For example, the term “terminator” in the terms index  114  can be returned in response to a user initiated search request and displayed as options for user selection. In this example, the options may correspond to a broadcast of the movie “Terminator”, on-demand availability of the movie, a trailer of the movie, a video game based on the movie, or a soundtrack of the movie. 
         [0043]    The term instances  318  corresponding to the “terminator” term indicate that if the user selects to view the trailer of the movie, then the trailer will be received at the user&#39;s client device for viewing. Similarly, if the user selects to watch a broadcast of the movie, or orders the movie from an on-demand service, the user&#39;s client device will be tuned to receive the broadcast or on-demand presentation of the movie. Alternatively, if the viewer selects the video game option, the video game can also be rendered from an on-demand service and/or an offer to purchase the video game can be displayed for the user. If the user selects the soundtrack option, then the music corresponding to the movie can be streamed to the user&#39;s client device such that the user can listen to the soundtrack. 
         [0044]      FIG. 4  illustrates an example of a search request that is input as a shape-based search request  400  using a “9-Key” alphanumeric keypad  402  to implement a predictive phonetic data search. In this example, a user inputs a request for a search term “LOUD” and inputs each letter of the term with shape-based pattern movements over the keypad such that the keypad is being utilized as a touch pad. For example, to enter the “L” input of the term at  404 , a user can form an L-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, and nine (9) key. 
         [0045]    Similarly, to enter the “0” input of the term at  406 , a user can form an 0-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, nine (9) key, six (6) key, three (3) key, two (2) key, and one (1) key. To enter the “U” input of the term at  408 , a user can form a U-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, nine (9) key, six (6) key, and three (3) key. To enter the “D” input of the term at  410 , a user can form a D-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, six (6) key, two (2) key, and one (1) key. 
         [0046]    The term manager  104  (as described with reference to  FIG. 1 ) can be implemented to receive the key entry sequences that each correspond to a letter of the requested search term, and determine each of the letters. The term manager  104  can then determine the numerical equivalent of the search input to be 5683 (i.e., the single key inputs for the term “LOUD”), and then locate the number in the numeric index  116  that corresponds to the numeric equivalent of the search term input. 
         [0047]    Methods for predictive phonetic data search, such as exemplary methods  500 - 700  described with reference to respective  FIGS. 5 ,  6 , and  7 , may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, functions, and the like that perform particular functions or implement particular abstract data types. The methods may also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, computer executable instructions may be located in both local and remote computer storage media, including memory storage devices. 
         [0048]      FIG. 5  illustrates an exemplary method  500  for predictive phonetic data search, and is described with reference to generating search terms and numeric equivalents. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof. 
         [0049]    At block  502 , text data is received from one or more text data sources. For example, text data can be received from text data source(s)  102 ( 1 - 1 V) ( FIG. 1 ) which can include electronic program guide data  102 ( 1 ), closed captions data that corresponds to television content  102 ( 2 ), and/or any other text data source  102 (M. At block  504 , search terms are identified in the text data. For example, the term manager  104  can identify terms in the received text data that may be requested by a user in a search 
         [0050]    At block  506 , a numeric equivalent of each search term is computed. For example, the term manager  104  computes a numeric equivalent  112  of the requested search term. At block  508 , additional numeric equivalents each corresponding to a phonetic equivalent of a search term are computed. For example, the term manager also computes additional numeric equivalents  118  that each correspond to a phonetic equivalent  122  of the requested search term. A phonetic equivalent of a search term can be a misspelling of the search term, a spelling of the search term that includes only consonants and no vowels, and/or a number in place of a word in the search term. The additional numeric equivalents are computed for any one or more of the phonetic equivalents. 
         [0051]    At block  510 , the numeric equivalent(s) associated with each search term are maintained in a numeric index. For example, the numeric equivalent(s)  118  are maintained in the numeric index  116  and include the numeric equivalent  120  corresponding to the correct spelling of the search term as well as the additional numeric equivalents  118  that each correspond to a phonetic equivalent  122  of the search term. The numeric equivalent(s)  118  can be searched in response to a search request for a particular search term. 
         [0052]    At block  512 , each numeric equivalent in the numeric index is mapped to the corresponding search term in a term index. For example, the numeric equivalents  118  corresponding to the requested search term in the numeric index  116  are mapped to the terms maintained in the terms index  114  such that when a numeric equivalent of a requested search term is located in the numeric index  116 , the corresponding search term in the term index  114  can be returned in response to a search request. 
         [0053]    At block  514 , one or more translations of a search term are generated and, at block  516 , the one or more translations of the search term are maintained in a translations index For example, the term manager  104  can generate translations of a term that are maintained in the translations index  304  ( FIG. 3 ). At block  518 , the one or more translations in the translations index are mapped to the corresponding search term in the term index. For example, the translations for the term “garden” in the translations index  304  are mapped to the term “garden” in the terms index  114  such that when the numeric equivalent of a requested search term is located in the numeric index, a translation of the search term can be returned in response to the search request. 
         [0054]      FIG. 6  illustrates an exemplary method  600  for predictive phonetic data search, and is described with reference to a search request for a particular search term. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof. 
         [0055]    At block  602 , a search request is received to locate a term. For example, the term manager  104  ( FIG. 2 ) can receive a search request from a user for a particular term. A search request can be received as inputs to a restrictive input device, such as a television remote control  208 , a cellular phone  210 , or a PDA  212  that only has a “9-Key” alphanumeric keypad  214 . A search request can be received as any one of: a sequence of characters, a sequence of letters each associated with a channel number input key on the keypad of the television remote control  208 , as a sequence of letters each associated with a telephone number input key entered on a keypad of the cellular phone  210 , as a text-based input that includes a sequence of characters that correspond to two or more words, as a combination of alphabetic character(s) and numeric character(s), as a phonetic equivalent of the term, as the phonetic equivalent which is a misspelling of the term, as the phonetic equivalent which includes only consonants in the term and no vowels, as the phonetic equivalent that includes a number in place of a word in the term, and/or any combination thereof. 
         [0056]    At block  604 , a numeric index is searched to locate a number that matches a numerical equivalent of the term. For example, the term manager  104  can search the numeric index  116  to locate a numeric equivalent  118  ( FIG. 1 ) of a requested search term. At block  606 , the term is obtained from a term index that is mapped to the number in the numeric index which matches the numerical equivalent of the term. For example, the numeric equivalent  118  of the search term is mapped to the term in the terms index  114 . 
         [0057]    At block  608 , the search request is processed to return the term based on a designated response instance of the term. For example, the term manager  104  can return the requested term based on a designated term response instance  318  ( FIG. 3 ) that corresponds to the ‘term in the terms index  114 . At block  610 , the term is returned in response to the search request. For example, the requested term can be returned for display and according to the designated term response instance, as a translation of the term, as a list of likely terms that correspond to the term in response to the search request, or as any one of a program schedule, a broadcast television selection, an on-demand selection, or an application program. 
         [0058]      FIG. 7  illustrates an exemplary method  700  for predictive phonetic data search, and is described with reference to a search request initiated as a shape-based input on a keypad. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof. 
         [0059]    At block  702 , a sequence of characters are received as a search request to locate a term, the sequence of characters each being entered as shape-based inputs that approximate a character. For example, a user can input a request for a search term by inputting each letter of the requested search term with shape-based pattern movements over a keypad  402  ( FIG. 4 ) such that the keypad is being utilized as a touch pad. At block  704 , the shape-based inputs that approximate a character are converted into at least one of an alphabetic or numeric character for each of the characters in the sequence. For example, the term manager  104  can receive the key entry sequences that each correspond to the letters “L,O,U,D” of the requested search term in the example  400 , and determine each of the letters. 
         [0060]    At block  706 , a numerical equivalent of the term is computed as determined from the sequence of characters. At block  708 , a numeric index is searched to locate a number that matches a numerical equivalent of the term. For example, the term manager  104  can then determine the numerical equivalent of the search input to be 5683 (i.e., the single key inputs for the term “LOUD” in  FIG. 4 ), and then locate the number in the numeric index  116  that corresponds to the numeric equivalent of the search input. At block  710 , the term is obtained from a term index that is mapped to the number in the numeric index which matches the numerical equivalent of the term. At block  712 , the term is returned in response to the search request. 
         [0061]      FIG. 8  illustrates various components of an exemplary electronic and/or computing device  800  in which embodiments of predictive phonetic data search can be implemented. The electronic and/or computing device  800  can be implemented as any one or more of the electronic, computing, and client devices described herein, and as any one or more of the servers, monitors, and managers of the exemplary television-based system  900  described with reference to  FIG. 9 . 
         [0062]    Electronic and/or computing device  800  includes one or more media content inputs  802  which may include Internet Protocol (IP) inputs over which streams of media content are received via an IP-based network. Device  800  further includes communication interface(s)  804  which can be implemented as any one or more of a serial and/or parallel interface, a wireless interface, any type of network interface, a modem, and as any other type of communication interface. A wireless interface enables device  800  to receive control input commands  806  and: other information from an input device, such as from remote control device  808 , PDA (personal digital assistant)  810 , cellular phonet or from another infrared (IR), 802.11, Bluetooth, or similar RF input device. 
         [0063]    A network interface provides a connection between the computing and/or client device  800  and a communication network by which other electronic and computing devices can communicate data with device  800 . Similarly, a serial and/or parallel interface provides for data communication directly between device  800  and the other electronic or computing devices. A modem facilitates device  800  communication with other electronic and computing devices via a conventional telephone line, a DSL connection, cable, and/or other type of connection. 
         [0064]    Computing and/or client device  800  also includes one or more processors  812  (e.g., any of microprocessors, controllers, and the like) which process various computer executable instructions to control the operation of device  800 , to communicate with other electronic and computing devices, and to implement embodiments of predictive phonetic data search. Device − 800  can be implemented with computer readable media  814 , such as one or more memory components, examples of which include random access memory (RAM), non-volatile memory (e.g., any one or more of a read-only memory (ROM), flash memory, EPROM, EEPROM, etc.), and a disk storage device. A disk storage device can include any type of magnetic or optical storage device, such as a hard disk drive, a recordable and/or rewriteable compact disc (CD), a DVD, a DVD+RW, and the like. 
         [0065]    Computer readable media  814  provides data storage mechanisms to store various information and/or data such as software applications and any other types of information and data related to operational aspects of the computing and/or client device  800 . For example, an operating system  816  and/or other application programs  818  can be maintained as software applications with the computer readable media  814  and executed on processor(s)  812  to implement embodiments of predictive phonetic data search. 
         [0066]    For example, device  800  can be implemented as a server and/or client device and the computer readable media  814  includes a program guide application  820  that is implemented to process program guide data  822  and generate program guides for display which enable a viewer to navigate through an onscreen display and locate broadcast programs, recorded programs, video on-demand programs and movies, interactive game selections, and other media access information or content of interest to the viewer. The computer readable media  814  can also includes a speech translator  824  and a term manager  826  to implement embodiments of predictive phonetic data search. 
         [0067]    The speech translator  824  can be implemented to receive an audio input of a search term, such as from a microphone or other audio input device (e.g., via a communication interface  904 ), and convert the audio input into a search request to locate the requested term. The term manager  826  can implement the various features and aspects of predictive phonetic data search as described herein, such as described with reference to the methods  500 - 700  described with reference to respective  FIGS. 5 ,  6 , and  7 . Although the term manager  826  is illustrated and described as a single application configured to implement embodiments of predictive phonetic data search, the term manager  826  can be implemented as several component applications distributed to each perform one or more functions in a server and/or client device in a television-based entertainment and information system. 
         [0068]    The computing and/or client device  800  also includes an audio and/or video output  828  that provides audio and video to an audio rendering and/or display system  830 , or to other devices that process, display, and/or otherwise render audio, video, and display data. Video signals and audio signals can be communicated from device  800  to a television  832  via an RF (radio frequency) link, S-video link, composite video link, component video link, analog audio connection, or other similar communication link. 
         [0069]      FIG. 9  illustrates an exemplary entertainment and information system  900  in which an IP-based television environment can be implemented, and in which embodiments of predictive phonetic data search can be implemented. System  900  facilitates the distribution of program content, program guide data, and advertising content to multiple viewers. System  900  includes a content provider  902  and television-based client systems  904 ( 1 -M each configured for communication via an IP-based network  906 . 
         [0070]    The network  906  can be implemented as a wide area network (e.g., the Internet), an intranet, a Digital Subscriber Line (DSL) network infrastructure, or as a point-to-point coupling infrastructure. Additionally, network  906  can be implemented using any type of network topology and any network communication protocol, and can be represented or otherwise implemented as a combination of two or more networks. A digital network can include various hardwired and/or wireless links  908 ( 1 -M, routers, gateways, and so on to facilitate communication between content provider  902  and the client systems  904 ( 1 -M. The television-based client systems  904 ( 1 -M receive program content, program guide data, advertising content, closed captions data, and the like from content server(s) of the content provider  902  via the IP-based network  906 . 
         [0071]    System  900  includes a media server  910  that receives program content from a content source  912 , program guide data from a program guide source  914 , and advertising content from an advertisement source  916 . In an embodiment, the media server  910  represents an acquisition server that receives the audio and video program content from content source  912 , an EPG server that receives the program guide data from program guide source  914 , and/or an advertising management server that receives the advertising content from the advertisement source  916 . 
         [0072]    The content source  912 , the program guide source  914 , and the advertisement source  916  control distribution of the program content, the program guide data, and the advertising content to the media server  910  and/or to other television-based servers. The program content, program guide data, and advertising content is distributed via various transmission media . 918 , such as satellite transmission, radio frequency transmission, cable transmission, and/or via any number of other transmission media. In this example, media server  910  is shown as an independent component of system  900  that communicates the program content, program guide data, and advertising content to content provider  902 . In an alternate implementation, media server  910  can be implemented as a component of content provider  902 . 
         [0073]    Content provider  902  is representative of a headend service in a television-based content distribution system, for example, that provides the program content, program guide data, and advertising content to multiple subscribers (e.g., the television-based client systems  904 ( 1 - 1 V)). The content provider  902  can be implemented as a satellite operator, a network television operator, a cable operator, and the like to control distribution of program and advertising content, such as movies, television programs, commercials, music, and other audio, video, and/or image content to the client systems  904 ( 1 - 1 V). 
         [0074]    Content provider  902  includes various components to facilitate media data processing and content distribution, such as a subscriber manager  920 , a device monitor  922 , and a content server  924 . The subscriber manager  920  manages subscriber data, and the device monitor  922  monitors the client systems  904 ( 1 -M (e.g., and the subscribers), and maintains monitored client state information. 
         [0075]    Although the various managers, servers, and monitors of content provider  902  (to include the media server  910  in one embodiment) are illustrated and described as distributed, independent components of content provider  902 , any one or more of the managers, servers, and monitors can be implemented together as a multi-functional component of content provider  902 . Additionally, any one or more of the managers, servers, and monitors described with reference to system  900  can implement features and embodiments of predictive phonetic data search. 
         [0076]    The television-based client systems  904 ( 1 -M can be implemented to include a client device  926  and a display device  928  (e.g., a television). A client device  926  of a television-based client system  904  can be implemented in any number of embodiments, such as a set-top box, a digital video recorder (DVR) and playback system, a personal video recorder (PVR), an appliance device, a gaming system, and as any other type of client device that may be implemented in a television-based entertainment and information system. In an alternate embodiment, client system  904 (IV) is implemented with a computing device  930  as well as a client device  926 . Additionally, any of the client devices  926  of a client system  904  can implement features and embodiments of predictive phonetic data search as described herein. 
         [0077]    Although embodiments of predictive phonetic data search have been described in language specific to structural features and/or methods, it is to be understood that the subject of the appended claims is not necessarily limited to the specific features or methods described. Rather, the specific features and methods are disclosed as exemplary implementations of predictive phonetic data search.
