Speech analysis system |
摘要 |
Speech analysis system in which segments of speech are analyzed. For the voiced/unvoiced decision use is made of the average magnitude or waveform intensity of successive speech segments. Basically a voiced decision is made when the waveform intensity increases monotonically over several segments by more than a given factor. An unvoiced decision is made if the waveform intensity drops below a given fraction of the maximum waveform intensity in the current voiced period. Refinements in the decisions are made by the use of fixed and adaptive thresholds.
