STUDY AND ANALYSIS OF SPEECH PARAMETERS AND BANDWIDTH COMPRESSION TECHNIQUES.
Abstract
Properties of the six stop consonants of English speech were studied with the aid of electronic gating circuitry and associated display equipment. The apparatus made possible transient-free blanking of an adjustable-duration section at adjustable location in an input test utterance recorded on a tape loop. Alternatively, a section of the utterance could be excised and heard in isolation from its context. Output gated speech was evaluated subjectively by listeners. Results provide information on the distribution in time of recognition clues to perception of the stop consonants, and on the dependence of this distribution upon such factors as clarity of enunciation. Bandwidth-compression experiments were also conducted, using a system to reconstruct speech from narrow-band transmitted analogs of zero-crossing rate, amplitude-envelope, and pitch period. Results suggest that a combination of the three analogs is preferable to previous operation without pitch. (Author)
