ABSTRACT:
A method and apparatus for compressing voice signals for storage and later retrieval is disclosed. The apparatus includes a microphone, a voice processor, a speaker and data storage. The apparatus forms a voice recognition template that associates a unique binary code word with each distinct syllabic sound in a particular language. When a user wishes to store voice signals using the apparatus, the user speaks into the microphone. For each syllable of the voice signal, the microphone provides the syllable to a voice processor. The voice processor formulates the frequency signature for the syllable. The frequency signal is compared to voice recognition template and the associated binary code word closest to the spoken syllable is stored within the data storage.
