No. 13/438,541, filed Apr. 3, 2012, which is a continuation of U.S. patent application Ser. No. 12/487,136, filed Jun. 18, 2009, all of which are incorporated by reference herein. 
    
    
     BACKGROUND 
     Automated methods for recognizing “named entities” (e.g., persons or places) in a body of text are known. The existing methods have been applied primarily to relatively short works, such as news reports, and highly specialized scientific works such as biomedical texts. Further, these methods have generally been applied to extract and compile information from texts, not to enhance the reading experience. 
     Written works such as works of fiction often contain a large number of character identities. The character identities and their attributes affect comprehension, interpretation, and understanding of the work and therefore have a profound effect on the reading experience. While most printed copies of written works simply present the work statically in black ink on white paper, the concept of electronic rendering of written works provides an opportunity to customize the presentation of a written work based on the characters within, making the written work more engaging for a user. Existing electronic rendering systems, however, fail to provide such customization.

     DETAILED DESCRIPTION 
     Disclosed embodiments enable the presentation of a written work based on information related to one or more character identities within the written work. The embodiments are not limited to specific types of written works such as works of fiction or biographies, as other types of written works are also contemplated. Written works include all forms of fiction (e.g., novels, short stories) and non-fiction (e.g., biographies, historical books), including combinations of fiction and non-fiction such as historical fiction. 
     While the term “character identity” is described in some embodiments herein with reference to a person, the term “character identity” in some embodiments includes any object referenced by the written work. Example character identities include people, personas, narrators, institutions, animals, machines, products, and devices. Character identities may be human, animal, supernatural, mythical, or divine. A written work may personify a thing, a place, or an intangible concept, thereby producing a character identity. 
     Some embodiments described herein enable an audible presentation of a written work using speech synthesis. Specifically, at least a portion of a written work is audibly rendered by a machine (e.g., an electronic book reader) using one or more electronic “voices”. A voice may be defined by information describing audible properties—such as pitch and phonation or “voicing”—to be used by a machine in rendering the voice. Alternatively, or in addition, a voice may be defined by audio samples of an actual person speaking utterances, words, and/or phrases. 
     A voice may be associated with voice attributes useful for describing the voice to a person such as a user of a computing device. For example, a voice may be associated with a sex, an age, an accent, a pitch, a speed, an ethnicity, a socioeconomic class (e.g., upper class or working class), a tribe, and/or a caste, though other voice attributes are also contemplated. Several types of voices may be available for audibly rendering a written work, including generic voices (e.g., a male adolescent), celebrity voices (e.g., a well-known actor), and custom voices. A user may create a custom voice, for example, by speaking utterances, words, and/or phrases from a script while a machine records the user&#39;s speech. The machine may include software for creating a voice based on the recording. 
     Referring to  FIG. 1 , a block diagram illustrating an exemplary system  100  is provided. The system  100  utilizes a server computing device  107  to process a written work. A user  101  accesses a user computing device  103  such as a browser client or electronic book reader to view information about the written work presented thereon. Written work information is communicated to the user computing device  103  through a network  105 . The network  105  is any type of network that communicatively couples computing devices. Examples of the network  105  include the Internet, a peer to peer (P2P) network, a local area network (LAN), or a wide area network (WAN). 
     The user computing device  103  is any device capable of accessing the network  105  and presenting character identity information to the user  101 . By way of example only, and not limitation, the user computing device  103  may include a laptop, a netbook, a desktop computer, a set-top box, a mobile entertainment device such as a vehicle entertainment system, a handheld device such as an electronic book reader, a cellular phone or smart phone, a mobile internet device, or a video gaming device. An exemplary user computing device  103  is described in detail with respect to  FIG. 2  below. 
     The server computing device  107  is communicatively coupled through the network  105  to the user computing device  103 . The server computing device  107  is any type of device that contains a processor operable to execute computer executable instructions and a memory to store and retrieve information. In some embodiments, the server computing device  107  hosts an e-commerce website. An exemplary server computing device  107  is described in detail with respect to  FIG. 3  below. 
     The server computing device  107  is communicatively coupled to a storage device  109 , upon which written works and related information (e.g., metadata) are stored. Voice information for use with written works may also be stored on the storage device  109 . A written work may be stored as an individual file, as a portion of a file, or as multiple files. The storage device  109  may include a database, in which case a written work and/or the written work&#39;s metadata may be stored in the database. The storage device  109  can be any form of computer-readable media, such as a hard disk drive, a solid state disk, or an optical disk drive. In some embodiments, the storage device  109  is integrated with the server computing device  107 . 
     Referring next to  FIG. 2 , an exemplary user computing device  103  is illustrated. The user computing device  103  includes a processor  205  for executing instructions. In some embodiments, instructions are stored in a memory area  210 . The processor  205  may include one or more processing units (e.g., in a multi-core configuration). The memory area  210  is any device allowing information such as executable instructions and/or written works to be stored and retrieved. The memory area  210  may include one or more computer readable media. 
     The user computing device  103  also includes at least one media output component  215  for presenting information (e.g., related to a written work) to the user  101 . The media output component  215  is any component capable of conveying information to the user  101 . In some embodiments, the media output component  215  includes an output adapter such as a video adapter and/or an audio adapter. An output adapter is operatively coupled to the processor  205  and operatively couplable to an output device such as a display device (e.g., a liquid crystal display (LCD), organic light emitting diode (OLED) display, or “electronic ink” display) or an audio output device (e.g., a speaker or headphones). For example, a video adapter may output a video signal using a Digital Visual Interface (DVI), HIGH-DEFINITION MULTIMEDIA INTERFACE (HDMI), and/or DisplayPort connection. An audio adapter may output an analog audio signal (e.g., through a headphone connector or other analog audio jack(s)) or a digital audio signal (e.g., through an optical, coaxial, or HDMI connector). The media output component  215  may include both an output adapter and an output device. In one embodiment, the media output component  215  includes a video adapter coupled to an integrated electronic ink display, which renders text and/or images on a front-lit panel. 
     In some embodiments, the user computing device  103  includes an input device  220  for receiving input from the user  101 . The input device  220  may include, for example, a keyboard, a pointing device, a mouse, a stylus, a touch sensitive panel (e.g., a touch pad or a touch screen), a gyroscope, an accelerometer, a position detector, or an audio input device. A single component such as a touch screen may function as both an output device of the media output component  215  and the input device  220 . 
     The user computing device  103  may also include a communication interface  225 , which is communicatively couplable to a remote device such as the server computing device  107 . The communication interface  225  may include, for example, a wired or wireless network adapter or a wireless data transceiver for use with a mobile phone network (e.g., Global System for Mobile communications (GSM),  3 G) or other mobile data network (e.g., Worldwide Interoperability for Microwave Access (WIMAX)). 
     Stored in the memory area  210  are, for example, computer readable instructions for providing a user interface to the user  101  via the media output component  215  and, optionally, receiving and processing input from the input device  220 . A user interface may include, among other possibilities, a web browser or an electronic book interface. Web browsers enable users, such as the user  101 , to display and interact with media (e.g., the written works) and other information typically embedded on a web page or a website on the server computing device  107 . An electronic book interface allows the user  101  to navigate a written work stored in the memory area  210  and render the written work in visible form (e.g., on an electronic ink display) or audible form (e.g., through a text-to-speech feature) using the media output component  215 . A user interface may also allow the user  101  to view written works in a catalog and download a written work to the user computing device  103  via the communication interface  225 . 
     In one embodiment, the processor  205  is programmed to retrieve a written work from the memory area  210 . The written work includes one or more character identities. For example, the written work may include metadata describing the character identities within the written work. The processor  205  is also programmed to identify one or more portions of the written work corresponding to one of the character identities. For example, the processor  205  may be programmed to retrieve, from the memory area  210  or via the communication interface  225 , associations between each character identity and portions of the written work corresponding to that character identity. 
     The processor  205  is also programmed to obtain presentation information for the identified portions. Presentation information may be obtained from within the written work, from elsewhere in the memory area  210 , or via the communication interface  225  (e.g., from a remote device such as the server computing device  107 ). In some embodiments, the user  101  selects presentation information using the input device  220 . The selected presentation information is associated with the written work, with a character identity, and/or with the identified portions and stored in the memory area  210 . 
     The processor  205  is also programmed to present the identified portions using the obtained presentation information via the media output component  215 . In some embodiments, the media output component  215  includes an audio adapter, and the presentation information for the identified portions includes a voice for the character identity corresponding to the identified portions. In some embodiments, the media output component  215  includes a video adapter, and the presentation information for the identified portions comprises a graphical scheme for the character identity corresponding to the identified portions. 
     In some embodiments, the processor  205  is programmed to request a written work from a remote device using the communication interface  225 . For example, the processor  205  may transmit a purchase request to the remote device. The processor  205  is also programmed to receive the written work from the remote device using the communication interface  225  and store the received written work in the memory area  210 . The processor  205  may be programmed to receive the written work in a “stream” of data. In such an embodiment, the processor  205  receives a portion of the written work via the communication interface  225  and stores the received portion in the memory area  210 . The processor  205  is programmed to present the received portion of the written work via the media output component  215 , regardless of whether all subsequent portions have been received. For example, a written work may be received in sequential portions through the communication interface  225 , and the user  101  may be presented, via the media output component  215 , the first of such sequential portions before the remaining portions are received. The user  101  may thus begin enjoying the written work without waiting for the entirety of the written work to be received. 
     Referring next to  FIG. 3 , an exemplary server computing device  107  for providing a written work for audible presentation at a user computing device is provided. The server computing device  107  includes a processor  305  for executing instructions. Instructions may be stored in the storage device  109 , for example. The processor  305  may include one or more processing units (e.g., in a multi-core configuration). 
     The processor  305  is operatively coupled to a communication interface  315  such that the server computing device  107  is capable of communicating with a client device such as the user computing device  103 . For example, the communication interface  315  may receive requests from the user computing device  103  via the network  105 , as illustrated in  FIG. 1 . 
     The processor  305  is also operatively coupled to a storage device  109 . The storage device  109  is any form of computer readable media suitable for storing a plurality of voices and one or more written works having at least one character identity. In some embodiments, the storage device  109  is integrated in the server computing device  107 . For example, the server computing device may include one or more hard disk drives as the storage device  109 . 
     The processor  305  is programmed to determine within a written work a character identity. Character identities may be determined, for example, using named entity recognition (NER) software such as CRFClassifier from the Natural Language Processing Group at Stanford University or GATE and ANNIE from the Natural Language Processing Group at the University of Sheffield. The NER software detects in the work textual strings (references) which refer to a character (referent). The NER software further identifies “coreferent” references, which share a common referent, and resolves them, such that a single referent is associated with multiple textual strings. 
     The processor  305  is also programmed to identify one or more portions of the written work associated with the character identity to create one or more character identity-portion associations. Portions of a written work associated with a character identity may be identified in several ways. For example, in many instances, the written work includes quotation marks around words “spoken” by a character identity. The quoted words may be preceded or followed by a reference to a particular character identity (e.g., a name or pronoun indicating the character identity) and possibly a word or phrase indicating speech (e.g., “said”, “exclaimed”, “replied”). In such instances, the quoted words may be identified and associated with the character identity. In other instances, a character identity reference may simply be followed by punctuation such as a colon and then the words “spoken” by the character, with or without quotation marks. Further, quoted words may appear without a proximate character identity reference. For example, where two character identities exchange dialogue, the written work may include a character identity reference near only some quoted portions (e.g., at the beginning of the exchange). It may generally be assumed that, where no contrary indication exists in the written work, the quoted portions alternate between the two character identities. Words that do not appear to be associated with any character identity may be interpreted as associated with a narrator of the written work. 
     The processor  305  is also programmed to store the character identity and the character identity-portion associations in the storage device  109 . In some embodiments, the storage device  109  includes a database such as a relational, hierarchical, or object oriented database, and the character identities and character-identity-portion associations are stored in the database. 
     The processor  305  is also programmed to provide the character identity and the character identity-portion associations from the storage device  109  to a user computing device (e.g., the user computing device  103 ) via the communication interface  315 . For example, the processor  305  may transmit the character identity and the character identity-portion associations to a user computing device as part of an electronic book. The processor  305  may also provide the character identity and character identity-portions in a separate transmission, upon receiving a request from the user computing device  103 . 
     The processor  305  is further programmed to provide a catalog having a plurality of voices from the storage device  109  to the user computing device via the communication interface  315 . The catalog may list all voices available from the storage device  109 , may list only voices determined to be appropriate for a particular written work or a particular character identity, or may list all voices available but indicate a subset of voices that are suggested or appropriate for a particular written work or a particular character identity. 
     For example, the processor  305  may be programmed to recognize at least one character identity attribute for a character identity and provide a voice suggestion to the user computing device based on the at least one character identity attribute. Relevant character identity attributes may include, for example, a gender, an approximate age, an ethnicity, and/or an era in which the character identity exists. More specifically, voices stored in the storage device  109  may include or be associated with voice attributes (e.g., gender, approximate age, ethnicity, era, socioeconomic class, tribe, caste, dialect, level of education). The processor  305  may be programmed to select for suggestion voices having an attribute or attributes that match a particular character identity&#39;s attribute(s). 
     Alternatively, or in addition, the processor  305  may be programmed to collect a plurality of character identity-voice associations from a plurality of other user computing devices and provide a voice suggestion to the user computing device based on the collected character identity-voice associations. This method may be used to suggest character identity-voice associations based on the character identity-voice associations selected by other users. 
     The processor  305  is also programmed to provide one of the plurality of voices from the storage device  109  to the user computing device via the communication interface  315 . For example, the processor  305  may receive a request for a voice from the user computing device. More specifically, the processor  305  may receive a purchase request for a voice from the user computing device, provide the voice to the user computing device, and charge a fee to an account associated with the user computing device. 
     In some embodiments, the processor  305  is operatively coupled to the storage device  109  via a storage interface  320 . The storage interface  320  is any component capable of providing the processor  305  with access to the storage device  109 . The storage interface  320  may include, for example, an Advanced Technology Attachment (ATA) adapter, a Serial ATA (SATA) adapter, a Small Computer System Interface (SCSI) adapter, a redundant array of inexpensive disks (RAID) controller, a storage area network (SAN) adapter, a network adapter, and/or any component providing the processor  305  with control over the storage device  109 . 
     In one embodiment, the storage device  109  stores at least one written work having a plurality of character identities therein. The written work may be stored as text, with or without formatting, such that the processor  305  may easily parse the work. In text format, the work may take the form of a plain text file, electronic book (e-book), word processor document, or any other suitable format. Alternatively, the written work may be stored as scanned images from a physical copy of the work; in this scenario, prior to processing the written work, the processor  305  pre-processes the images using optical character recognition (OCR) software to produce parseable text. 
     Referring next to  FIG. 4 , an exemplary flow chart  400  is provided for presenting a written work. A character identity is recognized  405  within a written work. A character identity may include a narrator or any other named or unnamed character identity. A voice is determined  410  for the character identity. In some embodiments, a user of the user computing device defines one or more preferences, such as a default voice for narrator character identities. A voice is determined  410  for the character identity based at least in part on the preference of the user. Any attribute that can be associated with a character identity may be associated with a narrator. 
     Further, determining  410  a voice may include determining an accent for the character identity based on an ethnicity of the character identity, a place of birth or residence of the character identity, an era or time period in which the character identity exists, and/or at least one quotation associated with the character identity (e.g., containing vernacular and/or slang terms). For example, a British accent may be selected for a character identity born in London or a character identity associated with a quotation containing the word “bloke”. Similarly, a southern United States accent may be selected for a character identity associated with a quotation containing the contraction “y&#39; all”. 
     One or more portions of the written work associated with the character identity are identified  415 . For example, quotations associated with the character identity may be identified. The determined voice is associated  420  with the identified portions to define one or more voice-portion associations. The voice-portion associations are stored  425  in a storage device. The voice-portion associations are provided  430  from the storage device to a user computing device for presentation of the identified portions using the determined voice. 
     In addition to recognizing  405  a character identity, one or more character identity attributes may be recognized  435 . For example, a gender, an approximate age, an ethnicity, and/or an era in which the character identity exists may be determined. A voice may be determined  410  for the character identity based at least in part on the recognized character identity attribute(s). For example, a user may define a preference relating a voice to at least one character identity attribute. 
     In some embodiments, the written work and character identity (including attributes, if recognized) are stored  440  in the storage device. Later, a request for the written work is received  445  from the user computing device. The storage device is checked to determine  447  whether the written work can be found. If not, an error is reported  448 . If so, the written work and character identity are retrieved  450  from the storage device and provided  455  to the user computing device. 
     Referring to  FIG. 5 , an exemplary flow chart  500  is provided for presenting a written work based on one or more character identity attributes. A character identity having at least one character identity attribute (e.g., gender, approximate age, ethnicity, and/or era in which the character identity exists) is recognized  505  within a written work. For example, an approximate age may be determined based on an explicit reference to a birth date, an age relative to another character identity (e.g., four years younger than a character with a known age), the date of a life event (e.g., a character identity&#39;s Bar Mitzvah ceremony), or one or more familial relationships. In some cases, such as when a birth date is provided, an exact age can be determined. In other cases, the information available provides for only an approximation of age. Where a written work contains a non-fictional character identity, one or more sources outside the written work may be consulted in determining an approximate age for the character identity. 
     The character identity is associated  510  with the written work and stored  515  in a storage device. A request for presentation information for the written work is received  520  from a remote device via a communication interface. The character identity is retrieved  525  from the storage device. Presentation information for the written work is determined  530  based on the at least one character identity attribute of the retrieved character identity. The presentation information for the written work is provided  535  to the remote device via the communication interface. The remote device renders the written work using the provided presentation information. Optionally, the written work is rendered  540  at the remote device using the presentation information. 
     In some embodiments, the presentation information includes information for presenting the written work in a catalog. For example, the presentation information may include a graphical scheme based on at least one character identity attribute of a character identity associated with the written work. A graphical scheme may include any graphical elements, including color, icons, graphics, photographs, and/or fonts. Graphical elements may be selected based on any character identity attributes, including gender, age, ethnicity, temperament, and/or personality. For example, an elegant script font may be selected for a gentle, feminine character identity, whereas a bold, block font may be selected for a gruff, masculine character identity. 
     In some embodiments, the presentation information includes a graphical scheme for displaying the written work in an electronic book format. For example, in either a catalog or an electronic book format, a colorful, informal graphical scheme may be selected for a children&#39;s book with a young character identity. Similarly, a graphical scheme may be applied to physical packaging for a written work (e.g., a cover for a book). 
     Referring next to  FIG. 6 , a screen shot is provided of a graphical interface  600  for displaying written work information in a catalog. The graphical interface  600  includes information about a written work, including a title and author  605 , summary information  610 , pricing information  615 , and availability information  620 . The graphical interface  600  also includes a character identity information section  625  containing names and brief descriptions of character identities from the written work. The character identity information section  625  also includes a button  630  allowing a user to navigate to a page listing character identity information in more detail. 
     A literary classic graphical scheme is applied to the graphical interface  600 . Specifically, the title and author  605 , summary information  610 , pricing information  615 , availability information  620 , and character identity information section  625  include text rendered in a formal script font. Character identity information section  625  also includes text rendered in a serif font, which is more formal than a sans-serif font, as is typically used in such graphical interfaces. Button  630  also includes text in a script font and has a formal, stylized shape. In addition to fonts and shapes, a graphical scheme such as the literary classic graphical scheme shown in  FIG. 6  may include colors and/or any graphical feature suitable for written works associated with the graphical scheme. 
     Referring next to  FIG. 7 , a screen shot is provided of a graphical interface  700  for displaying content for a written work. Specifically, the graphical interface  700  is an electronic book reader interface. The graphical interface  700  displays written work content including portions  705  associated with a narrator character identity, portions  710  associated with a second character identity, and a portion  715  associated with a third character identity. 
     The graphical interface  700  displays the portions  705 ,  710 , and  715  using presentation information. Specifically, each of the character identities is associated with a graphical scheme for graphically distinguishing portions associated with one character identity from portions associated with another character identity. In the example of  FIG. 7 , portions for each character identity are highlighted in a manner unique to the character identity. Alternatively, or in addition, the graphical interface  700  may highlight or otherwise distinguish portions of the written work based on character identity attributes. For example, a single formatting may be applied to all female character identities between the ages of 5 and 10 years old. 
     Referring to  FIG. 8 , a screen shot is provided of a graphical interface  800  for displaying a script based on a written work. In some embodiments, after portions associated with multiple character identities are identified, the portions may be arranged into a script. Graphical interface  800  illustrates the display of a script based on the content displayed in  FIG. 7 . Similar to graphical interface  700 , graphical interface  800  includes portions  805  associated with a narrator character identity, portions  810  associated with a second character identity, and a portion  815  associated with a third character identity. 
     Arranging portions of a written work into a script may include removing short (e.g., fewer than three words, fewer than five words, or fewer than ten words) portions associated with a narrator character identity. For example,  FIG. 7  includes the original text: 
     “But it is,” returned John, “according to Carl Franklin . . . you do know Carl, right?” 
     As indicated in  FIG. 7 , the original text includes two portions  710  associated with the second character identity and one portion  705  associated with the narrator character identity.  FIG. 8  illustrates the removal of the narrative portion to produce the following single portion  810  associated with the second character identity: 
     “But it is, according to Carl Franklin . . . you do know Carl, right?” 
     Removing a short narrative portion from the written work may render the script more readable for a user, especially where the narrative portion separates two portions associated with the same character identity. 
     In a graphical interface for displaying a written work, such as the graphical interfaces  700  and  800 , a reference (e.g., a name) for a character identity or a portion of the written work associated with a character identity may be selectable by a user via an input device. In response to the selection of the reference or portion, the graphical interface may display a context menu containing actions available in connection with the corresponding character identity. For example, the context menu may allow the user to specify how to format (e.g., highlight) portions of the written work associated with the character identity, view information about the character identity, and/or view other written works associated with the character identity. 
     In some embodiments, users of multiple devices may view a single written work. Each user is allowed to select a character identity or set of character identity attributes. Each user&#39;s device highlights portions of the written work associated with the character identity selected by the user or associated with any character identity with attributes matching the character identity attributes selected by the user. Two or more users may thus read the written work as group, with each user speaking the portions highlighted on that user&#39;s device. 
     Referring next to  FIG. 9 , a screen shot is provided of a graphical interface  900  for selecting a voice for a character identity in a written work. The graphical interface  900  includes a book title  905  and a table  910  of character identities associated with the book. In the example of  FIG. 9 , information for three character identities is provided in the table  910 . Specifically, the table  910  includes a name  915  for a narrator character identity, a name  920  for a second character identity, and a name  925  for a third character identity. The table  910  also includes character identity attributes  930  for the second character identity and character identity attributes  935  for the third character identity. The table  910  also includes a voice selector  940  for the narrator character identity, a voice selector  945  for the second character identity, and a voice selector  950  for the third character identity. 
     The graphical interface  900  is displayed with the voice selector  950  expanded to reveal voices available for the third character identity. As shown, the voice “Actor  4 ” is selected in voice selector  945  for the second character identity. As indicated by the character identity attributes  930 , the second character identity is a middle-aged woman. The voice selector  950  for the third character identity, which is an adult man, therefore does not include the voice “Actor  4 ”. The voice selector  950  does, however, include other actor voices, custom voices, and voices with descriptive names such as voice “Elderly Cockney man”  955 . 
     The graphical interface  900  may be used by a user of a user computing device at which a written work will be rendered. The user may specify default rules for selecting voices based on character identity attributes. For example, the user may specify that voice “Actor  1 ” be used for all male character identities over the age of 50 years old. For a newly obtained written work, therefore, the graphical interface  900  will indicate “Actor  1 ” for all male character identities over 50 years old. However, the user may override the default selections for one or more of the character identities. The user may also specify a default voice to be used for a narrator character identity in any written work. 
     The graphical interface  900  may also be used to define a default set or suggested set of character identity-voice associations to be provided to user computing devices. The default set or suggested set of character identity-voice associations may be stored by a server computing device so that it can later be retrieved for a user computing device. In some embodiments, a user of the user computing device is initially presented the graphical interface  900  with a voice selected for each character identity according to the default set or suggested set of character identity-voice associations. The user may override the default selections by manipulating one or more of voice selectors  940 ,  945 , and  950 . 
     In some embodiments, a user is presented with the graphical interface  900  at the time the user purchases a written work. The user may select from voices already stored in the user computing device and/or voices available for download—either freely or for purchase—from a remote device. If the user selects a voice available for purchase, the user computing device downloads the voice, and a fee is charged to an account associated with the user. The user may also select, download, and be charged for a voice after purchase. 
     A given character identity may appear in multiple written works, such as a series of novels. In such cases, it is contemplated that the corresponding character identity from each of the written works may be identified, and the resulting set of character identities and character identity attributes may be merged into a single character identity that is associated with all the corresponding written works. If the separate corresponding character identities were associated with other character identities (e.g., a child-parent relationship), the merged character identity may include all such associations. Further, if a voice has been associated with the character identity in one of the written works, but not in the other written work(s), the association of the character identity with the voice may be applied to the other written work(s). 
     Presentation information for audible presentation of a written work may include an indication of a time offset between portions. For example, in a case of alternating portions between two character identities (e.g., a quick exchange of dialogue), a relatively short time offset or even an overlap may be indicated. An interruption may be produced by indicating a negative time offset. 
     In one embodiment, character identity attributes are used to tailor advertising to meet the interests of individuals. Specifically, a customer profile is maintained by the operator of an online store for written works. The customer profile includes a purchase history of all written works purchased by the customer. The character identity attributes corresponding to the purchased written works are analyzed to determine a preferred set of character identity attributes for the customer. Other written works corresponding to character identity attributes that match the customer&#39;s preferred character identity attributes are recommended to the customer for purchase. Alternatively, or in addition, the customer profile includes demographic information such as a sex, an age, and/or a place of residence for the customer. Other customers having similar demographic information are identified to define similar customers. Character identity attributes occurring frequently in the purchase histories of the similar customers are analyzed to define a target set of character identity attributes. Written works corresponding to character identity attributes matching the target set of character identity attributes are recommended to the customer for purchase. 
     In another embodiment, an electronic catalog of written works is provided on a server computing device. The catalog provides a user of a user computing device the ability to search for written works by specifying one or more character identity attributes. The catalog returns to the user computing device only written works corresponding to the specified character identity attributes. The catalog may display with a written work the character identity attributes associated with the written work and/or other written works corresponding to at least some of the same character identity attributes. 
     In one embodiment, a director simulation is provided on a server computing device. The server provides to a user computing device one or more written works. A user of the user computing device selects a written work. The server computing device provides to the user computing device one or more character identities associated with the written work and, for each character identity, a plurality of real persons (e.g., actors and/or celebrities). The real persons may be provided based on one or more character identity attributes (e.g., age and/or gender). The user selects a real person for one or more of the provided character identities. The user may be presented an option to share the user&#39;s selections with others by transmitting a message via email or any other suitable form of communication and/or by publishing the user&#39;s selections to a social networking service.
