Bandwidth efficient digital voice communication system and method
First Claim
1. A bandwidth efficient digital voice communication system, comprising:
- a speech-to-text converter for converting a voice signal to a text representation;
a speech parameter extractor for extracting user identifiable parameters from the voice signal, wherein the speech-to-text converter includes a voice parameter manager that synthesizes the text representation and the user identifiable parameters; and
a text-to-speech converter for converting in real time the text representation and the user identifiable parameters into the user'"'"'s voice signal.

Abstract
A bandwidth efficient digital voice communication system (10) can include a speech-to-text converter (22) for converting a voice signal to a text representation, a speech parameter extractor (28) for extracting user identifiable parameters from a voice signal, and a text-to-speech converter (44) for converting the text representation and the user identifiable parameters from the voice signal in real time. The user identifiable parameters can be among pitch rate, gain, fundamental frequency, and formats. The speech-to-text converter can further include a text to phoneme segmentation module (24) providing flags to indicate a plurality of phoneme boundaries, an automatic phonetic segmentation module (26) coupled to the text to phoneme segmentation module and the speech parameter extractor, and a voice parameter manager (29) for receiving the text representation, the flags indicative of the plurality of phoneme boundaries, and the user identifiable parameters from the voice signal.

10. A mobile phone device, comprising:
-
a transceiver coupled to a microphone and an audio output device; and at least one processor coupled to the transceiver, wherein the processor is programmed to; receive a voice input signal from a user; convert the voice input signal to a users text representation; extract speech parameters from the voice input signal; and synthesize speech using the user'"'"'s text representation of the voice input signal and speech parameters from the caller to provide a real time synthesized voice signal substantially preserving an identity parameters of the caller. - View Dependent Claims (11, 12, 13, 14)
