20. A speech coding method responsive to an input speech signal provided by a system user, the method comprising the steps of: (a) recognizing words in the input speech signal in accordance with a speech recognition vocabulary to generate a first transcription comprising at least one phonetic token representative of the input speech signal; (b) generating a second transcription comprising at least one phonetic token representative of a word in the input speech signal that is not associated with the speech recognition vocabulary; (c) one of transmitting and storing at least one of the phonetic tokens; and (d) generating a synthesized speech signal which is representative of the input speech signal provided by the system user using at least one of a plurality of pre-enrolled phonetic tokens that substantially matches at least one of the phonetic tokens.

The speech coding method of claim 20, wherein step (d) further comprises the steps of: selecting the pre-enrolled phonetic tokens that substantially match the phonetic tokens; associating pre-stored waveforms to the pre-enrolled phonetic tokens; adjusting the pre-stored waveforms in accordance with acoustic parameters associated with voice characteristics of the system user; and linking the pre-stored waveforms to form the synthesized speech signal.
