1. A method for creating a compressed data representation of a human speech utterance which includes voiced sounds and unvoiced sounds, said method comprising the steps of: detecting each occurrence of a voiced sound within said human speech utterance, analyzing each detected occurrence of a voiced sound within said human speech utterance to determine a duration thereof and a single representative data frame which when utilized repetitively most nearly approximates said voiced sound; detecting each occurrence of an unvoiced sound within said human speech utterance; analyzing each detected occurrence of an unvoiced sound within said human speech utterance to determine a spectral content thereof and amplitude variations therein; creating a preliminary compressed data representation of said human speech utterance which includes an encoded representation of duration and a single representative data frame representative of each detected occurrence of a voiced sound and an encoded representation of a spectral content and amplitude variations representative of each detected occurrence of an unvoiced sound; comparing portions of said preliminary compressed data representation of said human speech utterance with portions of previously created compressed data representations of human speech utterances which are stored at identified locations to determine if similarities exist; and creating a final compressed data representation of said human speech utterance which includes an identification of locations of similar portions of previously created compressed data representations of human speech utterances; an encoded representation of duration and a single representative data frame representative of each detected occurrence of a voiced sound which is not similar to a portion of a previously created compressed data representation of a human speech utterance; and, an encoded representation of a spectral content and amplitude variations representative of each detected occurrence of an unvoiced sound which is not similar to a portion of a previously created compressed data representation of a human speech utterance.

The method for creating a compressed data representation of a human speech utterance according to claim 1, wherein said human speech utterance includes periods of silence and wherein said method further includes the step of detecting each occurrence of a period of silence within said human speech utterance.
