## Background
BACKGROUND OF THE INVENTION
Mobile communication devices are continually increasing in popularity. Such mobile communication devices include, for example and without limitation, cellular phones, paging devices and personal digital assistants. Mobile communication devices provide the user with the capability to conduct communications in a large variety of environments, some of which may not be appropriate for certain types of communications (e.g., voice communications). As a non-limiting example, it is generally inappropriate to conduct telephone conversations in quiet areas (e.g., a movie theater during a movie, in a conference room during a meeting, in a church during a service, etc.). Also for example, it may occasionally be difficult or impossible to conduct telephone conversations in noisy environments (e.g., at a sporting event, at a construction area, at a noisy nightclub, etc.).

Also for example, the mobile communication device may comprise characteristics of a voice-capable paging device, voice-capable portable email device, voice-capable personal digital assistant (PDA) or pocket computer with mobile communication capability, etc. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular type of mobile communication device.
The exemplary method 100 may begin executing at step 105. The exemplary method 100 may begin executing for any of a variety of reasons. For example and without limitation, the exemplary method 100 may begin executing upon power-up or reset of a mobile communication device implementing the exemplary method 100. Also for example, the exemplary method 100 may begin executing in response to a user command to begin (e.g., a command to initiate a communication or respond to a communication). Further for example, the exemplary method 100 may begin executing in response to a signal received at the mobile communication device from another communication device. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular initiating cause or condition.
The exemplary method 100 may, at step 110, comprise establishing a communication link (e.g., a wireless communication link) with a second communication device. The second communication device may comprise characteristics of any of a variety of communication devices. For example and without limitation, the second communication device may comprise characteristics of a cellular telephone, portable telephone or wired telephone. Also for example, the second communication device may comprise characteristics of a voice-capable paging device, voice-capable portable email device, voice-capable personal digital assistant (PDA) or pocket computer with mobile communication capability, etc. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular type of second communication device.
The communication link may comprise characteristics of any of a variety of types of communication links. For example and without limitation, the communication link may comprise characteristics of a cellular telephone communication link. Also for example, the communication link may comprise characteristics of any of a large variety of telecommunication and/or computer communication links. The communication link may further, for example, comprise characteristics of any of a variety of communication media (e.g., wireless RF, non-tethered optical, etc.).
The communication link may additionally, for example, be capable of communicating voice information and any of a variety of other information types. For example and without limitation, the communication link may be capable of communicating video, graphical, pictorial, data and/or textual information.
Step 110 may, for example, comprise establishing the communication link in accordance with any of a variety of communication protocols and/or standards. For example and without limitation, step 110 may comprise establishing the communication link in accordance with any of a variety of cellular telecommunication protocols and/or standards (e.g., GSM, GPRS, EDGE, HSCSD, CDMA, WCDMA, TDMA, PDC, SMS, etc.). Also for example, step 110 may comprise establishing the communication link in accordance with any of a variety of computer communication protocols and/or standards (e.g., WLAN, WiFi, IEEE 802.11, IEEE 802.15, Bluetooth, UltraWideBand, Zigbee, IP, Ethernet or IEEE 802.3, X.25, token ring or IEEE 802.5, etc.).
In general, step 110 may comprise establishing a communication link with a second communication device. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular type of second communication device, any particular type of communication link, or any particular manner of establishing a communication link.
Note that though the present discussion will generally refer to communication between the mobile communication device and a second communication device, such a one-to-one correspondence is merely illustrative. The scope of various aspects of the present invention should not be limited by any particular number of communication devices with which the mobile communication device may communicate.
The exemplary method 100 may, at step 115, comprise receiving voice communication information from the second communication device (e.g., over the communication link established at step 110). For example and without limitation, step 115 may comprise receiving voice communication information corresponding to a second person utilizing the second communication device to speak to the user of the mobile communication device.
The exemplary method 100 may, at step 117, comprise communicating at least a portion of the received voice information to the user (e.g., in a substantially silent manner from the perspective of people other than the user of the mobile communication device). For example, step 117 may comprise generating an audio output corresponding to the received voice information at an ear speaker, earphone, headset or other audio output device such that the generated audio output may be presented to a user of the mobile communication device without being audible to other people in the proximity of the mobile communication device. Such presentation of incoming voice information may provide voice information to a user of the mobile communication device without causing noise interference to others.
The exemplary method 100 may, at step 120, comprise receiving a user input (e.g., from a person utilizing the mobile communication device to communicate). The user input may comprise characteristics of any of a variety of user inputs. For example and without limitation, the user input may comprise a key press signal (e.g., associated with a key press on a numeric or alpha-numeric keypad). Also for example, the user input may comprise a signal indicative of a user touch screen selection. Further for example, the user input may comprise a signal indicative of cursor movement and/or selection (e.g., a touch pad, thumbwheel, arrow key, select button, etc.). The scope of various aspects of the present invention should not be limited by characteristics of a particular type of user input that may be received at a mobile communication device.
Step 120 may comprise receiving a user input in any of a variety of manners. For example and without limitation, step 120 may comprise passively receiving an input from a user. Also for example, step 120 may comprise actively soliciting an input from a user. For example, step 120 may comprise generating a visual output (e.g., a menu) identifying a set of voice messages from which the user is to choose. Such voice messages may, for example, comprise prerecorded voice messages (e.g., characterized by a generic voice or the user's voice). For example, the prerecorded voice messages may correspond to a set of voice messages prerecorded by the user with the user's voice.
A menu of voice messages (e.g., a visual menu) may comprise characteristics of any of a variety of menu types. For example, a menu may comprise keywords or icons associated with particular words or voice messages. Also for example, a menu may comprise key letters, numbers or other symbols associated with particular words or voice messages. Such keywords, symbols, letters, numbers or other symbols may be a predefined set or may, for example, be definable (e.g., user selectable or designable).
In various non-limiting exemplary scenarios, step 120 may comprise associating one of a plurality of sets of prerecorded voice messages with a particular communication. For example, a first set of prerecorded voice messages may comprise messages recorded in a first language, and a second set of prerecorded voice messages may comprise messages recorded in a second language. In another example, a first set of prerecorded voice messages may comprise messages recorded for professional conversations, and a second set of prerecorded voice messages may comprise messages recorded for personal conversations. In yet another example, a first set of prerecorded voice messages may comprise messages recorded for conversations with a first person (or first group of people), and a second set of prerecorded voice messages may comprise messages recorded for conversations with a second person (or second group of people).
In a non-limiting exemplary scenario where there is such a plurality of sets of prerecorded voice messages, step 120 may comprise associating one of the plurality of sets of prerecorded voice messages with a particular communication in any of a variety of manners. For example and without limitation, step 120 may comprise associating a set of prerecorded voice messages with a particular communication based, at least in part, on the identity of the second communication device or a user thereof. Also for example, step 120 may comprise associating a set of prerecorded voice messages with a particular communication based, at least in part, on a user input (e.g., acquired at step 120 or another step) indicating a user selection of a particular set. Further for example, step 120 may comprise associating a set of prerecorded voice messages with a particular communication based, at least in part, on date, time, geographical location, present user of the mobile communication device, etc. In general, in various non-limiting exemplary scenarios, step 120 may comprise associating one of a plurality of sets of prerecorded voice messages with a particular communication. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular set of prerecorded voice messages or any particular manner of associating a particular set of prerecorded voice messages with a particular communication.
In general, step 120 may comprise receiving a user input. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular user input, any particular manner of receiving a user input or any particular manner of interacting with a user to receive a user input.
The exemplary method 100 may, at step 130, comprise determining, based at least in part on the user input (e.g., as received at step 120), a voice message from a plurality of voice messages (e.g., to communicate to the second communication device with which a communication link was established at step 110).
Step 130 may comprise determining a voice message in any of a variety of manners. For example and without limitation, step 130 may comprise selecting, based at least in part on a user input (e.g., as received at step 120), a voice message from a set of voice messages. Such voice messages may, for example, comprise prerecorded voice messages (e.g., recorded in a generic voice or in the user's voice). A set of prerecorded voice messages may, for example, comprise a fundamental (e.g., logically complete) set of statements with which one side of a basic two-sided conversation may be conducted. For example and without limitation, a set of prerecorded voice messages may comprise statements, such as: “yes,” “no,” “maybe,” “I can't talk now, but I'm listening,” “I will call you as soon as I can,” “I understand,” “please leave a short message, to which I can respond with short prerecorded messages,” “later,” “tomorrow,” “call someone else,” “use your best judgment,” “please hold while I move to a more appropriate location,” “I have to hang up now,” “please continue,” “hello,” “good-bye,” “thank you,” “please repeat,” “please wait while a type an answer,” etc.
Step 130 may also, for example, comprise determining a voice message by determining a voice message to be synthesized based, at least in part, on a user input (e.g., as received at step 120). For example and without limitation, step 130 may comprise determining, based at least in part on a user input, a voice message to be synthesized by performing text-to-speech or phonics-to-speech synthesis. The user may, for example at step 120, spell a word or phrase or phonetically construct a pronunciation for a word or phrase, and step 130 may then comprise determining the word or phrase to be synthesized based, at least on part, on the input spelling or phonetic representation.
In a non-limiting exemplary scenario, step 130 may comprise generating an audio output indicative of the determined voice message. For example, step 130 may comprise presenting such an audio output to a user of the mobile communication device through an ear speaker, earpiece, headset or other audio output device such that people in the proximity of the mobile communication device will not hear the audio output, or in a manner that will be minimally affected by external sound noise at the user's locale. A user may thus hear the determined voice message. For example and without limitation, step 130 may comprise generating an audio output corresponding to the determined voice message and providing the user an opportunity to confirm the determined voice message or specify that an alternative voice message be determined prior to the determined voice message being communicated to the second communication device (e.g., at step 140, discussed below). Also for example, step 130 may comprise generating an audio output corresponding to the determined voice message concurrently with the communication of the determined voice message to the second communication device. In an exemplary scenario where the determined voice message is output to the user, step 130 may comprise mixing the determined voice message with other audio that may be provided to the user (e.g., audio associated with an incoming voice signal from the second communication device).
In general, step 130 may comprise determining a voice message from a plurality of voice messages based, at least in part, on a user input (e.g., as received at step 120). Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular manner of determining a voice message (e.g., selecting from a set or determining a voice message to be synthesized) or any particular manner of providing feedback to a user to notify the user of a determined voice message.
The exemplary method 100 may, at step 140, comprise communicating the determined voice message (e.g., as determined at step 130) to the second communication device over a communication link (e.g., as established at step 110). Step 140 may comprise communicating the determined voice message to the second communication device in any of a variety of manners (e.g., depending on the nature of the second communication device and/or the communication link established with the second communication device). As discussed previously with regard to step 110, the second communication device may comprise characteristics of any of a variety of communication device types, and the communication link may comprise characteristics of any of a large variety of types of communication links. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular manner of communicating a voice message.
Step 140 may for example and without limitation, comprise generating an audio signal corresponding to the determined voice message. Step 140 may, for example, comprise performing such generating in any of a plurality of manners. For example and without limitation, step 140 may comprise retrieving voice message information (e.g., digitally sampled voice message information) corresponding to a determined voice message from memory and processing such retrieved voice message information to generate an audio signal. Also for example, step 140 may comprise performing any of a variety of voice synthesis techniques (e.g., text or phonics based voice synthesis techniques) to generate an audio signal. The scope of various aspects of the present invention should not be limited by characteristics of any particular manner of generating an audio signal.
Step 140 may, for example and without limitation, comprise selecting between a voice signal originated at a microphone of the mobile communication device and a generated voice signal (e.g., corresponding to the voice message determined at step 130) and transmitting the selected voice signal. Step 140 may alternatively, for example, comprise mixing a voice signal originated at a microphone of the mobile communication device and a generated voice signal (e.g., corresponding to the voice message determined at step 130) and transmitting the selected voice signal. In general, step 140 may comprise communicating the determined voice message (e.g., as determined at step 130) to at least the second communication device. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular manner of communicating the determined voice message.
The exemplary method 100 may, at step 150, comprise performing continued processing activities. Step 150 may comprise performing any of a large variety of processing activities. Such processing activities may, for example and without limitation, comprise those generally associated with mobile communication.
For example, step 150 (or another step) may comprise interfacing with a user to define a set of voice messages. Such interfacing may, for example, comprise interfacing with a user to record one or more prerecorded voice messages. Also for example, such interfacing may comprise defining visible indicia (e.g., text, icons, numbers, etc.) to represent various prerecorded voice messages on an output display of the mobile communication device.
Also for example, in a non-limiting exemplary scenario including a plurality of sets of prerecorded voice messages, step 150 (or another step) may comprise interfacing with a user to define a plurality of sets of voice messages. Such interfacing may, for example, comprise interfacing with a user to associate a particular set of voice messages with one or more particular selection characteristics (e.g., user input, communication device ID, caller ID, user ID, language, date, time, location, etc.). Such an association may then, for example, be utilized to associate a particular set of voice messages with a particular communication.
Note that various portions of such interfacing may be performed by the mobile communication device or may be performed by another device (e.g., a personal computer) that may be coupled to the mobile communication device.
Step 150 may also, for example, comprise receiving a user input (e.g., a “mode” input) associated with setting or changing operation of the mobile communication device between a silent communication mode (e.g., communicating in accordance with steps 115-140) and a non-silent communication mode (e.g., where the user speaks normally into the mobile communication device) and vice-versa. Step 150 may then, for example, comprise switching between a silent and non-silent communication mode based on such a received user input. In a non-limiting exemplary scenario, such switching may comprise communicating a message to another communication device indicating that such a mode switch has occurred.
Step 150 may also, for example, comprise receiving a signal (e.g., a “mode” signal) from another communication device associated with setting or changing operation of the mobile communication device between a silent communication mode (e.g., communicating in accordance with steps 120-140) and a non-silent communication mode (e.g., where the user speaks normally into the mobile communication device). Step 150 may then, for example, comprise switching between a silent and non-silent communication mode based on such a received signal.
Step 150 may further, for example, comprise communicating various information, in addition to voice information, between the mobile communication device and the second communication device. For example and without limitation, step 150 may comprise communicating video information and/or textual information between the mobile communication device and the second communication device. For example, step 150 may comprise interfacing with the user to enter an operating mode in which the user may utilize the mobile communication device to communicate alphanumeric characteristics (or audible representations thereof) with the second communication device. Further for example, step 150 may comprise communicating data information (e.g., file information) with the second communication device.
Step 150 may additionally, for example, comprise receiving a second user input and, in response to the second user input, abort communicating the determined voice message to another communication device at step 140. In a non-limiting exemplary scenario, a user may determine that an incorrect or unnecessarily long message is being communicated at step 140 and enter the second user input to discontinue transmission of the errant or unnecessarily long message. Execution of the exemplary method 100 may, for example, return to step 120 to receive additional user input.
In general, step 150 may comprise performing any of a large variety of continued processing activities. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular type of continued processing.
The exemplary method 100 was presented to provide specific illustrations of various generally broader aspects of the present invention. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of the exemplary method 100.

In general, the first communication interface module 212 may be adapted to establish a communication link with at least a second communication device. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular type of second communication device, any particular type of communication link, or any particular manner of, or mechanism for, establishing a communication link.
Note that though the present discussion will, at times, generally refer to communication between the exemplary mobile communication device 200 and a second communication device, such a one-to-one correspondence is merely illustrative. The scope of various aspects of the present invention should not be limited by any particular number of communication devices with which the mobile communication device 200 may communicate.
The general communication control module 222, which will discussed below may, for example, utilize the first communication interface module 212 to receive voice communication information from the second communication device (e.g., over an established communication link). For example and without limitation, the general communication control module 222 may utilize the first communication interface module 212 to receive voice communication information corresponding to a second person utilizing the second communication device to speak to the user of the mobile communication device 200.
Also for example, the general communication control module 222 may, for example, utilize the user interface module(s) 230, which will be discussed below, to communicate at least a portion of the received voice information to the user (e.g., in a substantially silent manner from the perspective of people other than the user of the mobile communication device).

Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular user input, any particular manner of (or mechanism for) receiving a user input or any particular manner of (or mechanism for) interacting with a user to receive a user input.
As discussed previously, the mobile communication device 200 may comprise a voice message generator module 224. The voice message generator module 224 may be adapted to determine and/or generate a voice message based, at least in part, on a user input (e.g., as received by the user interface module(s) 230). The voice message generator module 224 may, for example and without limitation, share various functional characteristics with steps 130 and 140 of the exemplary method 100 illustrated in FIG. 1 and discussed previously.
The voice message generator module 224 may be adapted to determine and/or generate a voice message in any of a variety of manners. For example and without limitation, the voice message generator module 224 may be adapted to select, based at least in part on a user input (e.g., as received by the user interface module(s) 230), a voice message from a set of voice messages (e.g., as might be stored in the memory 240). Such voice messages may, for example, comprise prerecorded voice messages (e.g., recorded in a generic voice or in the user's voice). As discussed previously with regard to step 130 of the exemplary method 100, a set of prerecorded voice messages may, for example, comprise a fundamental set of statements with which one side of a basic two-sided conversation may be conducted. For example and without limitation, a set of prerecorded voice messages may comprise statements, such as: “yes,” “no,” “maybe,” “I can't talk now, but I'm listening,” “I will call you as soon as I can,” “I understand,” “please leave a short message, to which I can respond with short prerecorded messages,” “later,” “tomorrow,” “call someone else,” “use your best judgment,” “please hold while I move to a more appropriate location,” “I have to hang up now,” “please continue,” “hello,” “good-bye,” “thank you,” “please repeat,” “please wait while a type an answer,” etc.
The voice message generator module 224 may also, for example, be adapted to determine and/or generate a voice message by determining a voice message (or characteristics of a voice message) to synthesize based, at least in part, on a user input (e.g., as received by the user interface module(s) 230) and then synthesizing the determined voice message based. For example and without limitation, the voice message generator module 224 may be adapted to perform text-to-speech or phonics-to-speech synthesis, based on the user input. The user may, for example utilizing the user interface module(s) 230, spell a word or phrase or phonetically construct a pronunciation for a word or phrase, and the voice message generator module 224 may then be adapted to synthesize the word or phrase based, at least on part, on the input spelling or phonetic representation.
In a non-limiting exemplary scenario, the voice message generator module 224 may be adapted to generate an audio output (e.g., utilizing the user interface module(s) 230) indicative of the determined voice message. For example, the voice message generator module 224 may be adapted to present such an audio output to a user of the mobile communication device 200 through an ear speaker, earpiece, headset or other audio output device such that people in the proximity of the mobile communication device 200 will not hear the audio output, or in a manner that will be minimally affected by external sound noise at the user's locale. A user may thus hear the determined voice message. For example and without limitation, the voice message generator module 224 may be adapted to utilize the user interface module(s) 230 to generate an audio output corresponding to the determined voice message and provide the user an opportunity to affirm the determined voice message or specify that an alternative voice message be determined prior to the determined voice message being transmitted to the second communication device (e.g., by the first communication interface module 212, as discussed below). Also for example, the voice message generator module 224 may be adapted to generate an audio output of the determined voice message (e.g., utilizing the user interface module(s) 230) concurrently with the communication of the determined voice message (e.g., utilizing the first communication interface module 212) to the second communication device. In an exemplary scenario where the determined voice message is output to the user, the voice message generator module 224 may be adapted to mix the determined voice message with other audio that may be provided to the user by the user interface module 230 (e.g., audio associated with an incoming voice signal from the second communication device).
In general, the voice message generator module 224 may be adapted to determine and/or generate a voice message based, at least in part, on a user input (e.g., as received by the user interface module(s) 230). Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular manner of (or mechanism for) determining or generating a voice message (e.g., selecting or synthesizing a voice message) or any particular manner of (or mechanism for) providing feedback to a user to notify the user of a determined voice message.

Also for example, the general communication control module 222 may be adapted to utilize the first communication interface module 212 to communicate voice information (and/or other information) to and from another communication device.
For example, the general communication control module 222 may be adapted to utilize the first communication interface module 212 to communicate a determined voice message (e.g., as determined and/or generated by the voice message generator module 224) to the second communication device over an established communication link (e.g., as established by the first communication interface module 212). The general communication control module 222 may be adapted to utilize the first communication interface module 212 to communicate determined voice messages to the second communication device in any of a variety of manners (e.g., depending on the nature of the second communication device and/or the communication link established with the second communication device). As discussed previously, the second communication device may comprise characteristics of any of a variety of communication device types, and the communication link may comprise characteristics of any of a large variety of types of communication links. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular manner of communicating a voice message.
As mentioned previously, the exemplary mobile communication device 200 may (e.g., optionally) comprise a second communication interface module 214 and additional communication interface modules, depending on the device configuration. Such a second communication interface module 214 may be identical to the first communication interface module 212 or may be different (e.g., adapted to communicate in a different manner). In a non-limiting exemplary scenario, the first communication interface module 212 may be adapted to communicate with another communication device over a telecommunication network, and the second communication interface module 214 may be adapted to communicate over a computer network. The scope of various aspects of the present invention should not be limited by the existence or non-existence of such a second communication interface module 214 or by characteristics of any particular type of communication interface module.
Also as mentioned previously, the exemplary mobile communication device 200 may comprise a memory 240. The memory 240 may, for example, be adapted to store prerecorded voice message information (e.g., information related to digital voice message sampling or information related to voice synthesis processing). The memory 240 may also, for example, be adapted to store software instructions, which may be executed by a processor of the mobile communication device 200. The memory 240 may comprise characteristics of any of a variety of memory types. Accordingly, the scope of various aspects of the present invention should not be limited by characteristics of any particular type of memory.
Additionally, for example and without limitation, the operational control module(s) 220 may be adapted to, in response to a particular user input, abort communicating a determined voice message to the second communication device. In a non-limiting exemplary scenario, a user may determine that an incorrect or unnecessarily long message is being communicated to another communication device and enter the particular user input to discontinue transmission of the errant or unnecessarily long message.
