Third International Conference on Spoken Language Processing (ICSLP 94)
The three-channel pitch determination algorithm (PDA) presented in this paper combines a short-term analysis PDA, which derives fundamental frequency via a period- icity criterion, and two time-domain PDAs that determine the instants of glottal closure according to local signal criteria. The first of these algorithms correlates the speech signal with an estimate of the impulse response of the vocal tract; the second one applies a neural network. The reliability of these time-domain PDAs is increased by constraints on the range of Fq imposed by the short-term analysis PDA. First results show that the algorithm can be applied for both accurate pitch period determination of running speech and voice quality measurements, particularly the measurement of voice jitter.
