Computer Programs for Measuring Variations in Speech

摘要

The measurement of variations in speech is investigated. Computer programs developed to study speech patterns determine the word boundaries and spacing, the fundamental pitch and the formants of words, and classification of the speech as voiced or unvoiced. The potential use of the computer program is demonstrated using synthetic speech. A synthetic voice generator was used to generate voice patterns from a known speaker in two different voice patterns by changing pitch and breathing parameters. The patterns were digitized and processed on a VAX 11/780 computer for analysis. The computed parameters agree with those used to generate the synthetic speech. It is planned to use these programs in future investigations of the relation between work load of subjects who perform data entry tasks using automatic voice recognition systems. (KR)
