13. A computing device that functions as a cell phone comprising: a user perceivable output device; a set of phone keys including at least a standard twelve key phone key pad; one or more processing devices; one or more memory devices readable by the processing devices; a microphone or audio input from which said telephone can receive electronic representations of sound; a speaker or audio output for enabling an electric representation of sound produced in said device to be transduced into a corresponding sound; transmitting and receiving circuitry; programming recorded in the memory including: telephone programming having instructions for performing telephone functions including making and receiving calls using said transmitting and receiving circuitry to transmit—to another telephone with which said cell phone is sharing a call—audio signals received from said microphone or audio input, and to receive audio signals transmitted from said telephone with which said cell phone is sharing a call and to supply said audio signals to said speaker or audio output; and speech recognition programming for performing large vocabulary speech recognition that responds to the electronic representations of the sound of a sequence of one or more utterances received from the microphone or audio input by producing a text output corresponding to the one or more words recognized as corresponding to the utterances; and audio recording programming for recording an electronically readable representation of said sound in one or more of said memory devices; audio playback programming for playing back said recorded sound representation and providing a corresponding audio signal to said speaker or audio output.
13. A computing device that functions as a cell phone comprising: a user perceivable output device; a set of phone keys including at least a standard twelve key phone key pad; one or more processing devices; one or more memory devices readable by the processing devices; a microphone or audio input from which said telephone can receive electronic representations of sound; a speaker or audio output for enabling an electric representation of sound produced in said device to be transduced into a corresponding sound; transmitting and receiving circuitry; programming recorded in the memory including: telephone programming having instructions for performing telephone functions including making and receiving calls using said transmitting and receiving circuitry to transmit—to another telephone with which said cell phone is sharing a call—audio signals received from said microphone or audio input, and to receive audio signals transmitted from said telephone with which said cell phone is sharing a call and to supply said audio signals to said speaker or audio output; and speech recognition programming for performing large vocabulary speech recognition that responds to the electronic representations of the sound of a sequence of one or more utterances received from the microphone or audio input by producing a text output corresponding to the one or more words recognized as corresponding to the utterances; and audio recording programming for recording an electronically readable representation of said sound in one or more of said memory devices; audio playback programming for playing back said recorded sound representation and providing a corresponding audio signal to said speaker or audio output. 18. A computing device as in claim 13 wherein the device's programming further includes instructions for enabling a user to select a sub-portion of said recorded sound representation which had not previously been recognized and to have said large vocabulary speech recognition performed upon said selected sub-portion.
