Pitch and Voicing in Speech Digitization.
Abstract
A critical element of any low or medium bit rate (< 16 kbps) speech digitization system is the pitch extraction and voicing mechanism. Any digitization system in this low to medium bit rate region will require a good pitch extraction technique as a key part of the system. In this study previous pitch extraction techniques are reviewed in the light of current pitch extraction requirements for speech digitization. Two promising new pitch extraction algorithms are suggested: the multiband pitch period estimation technique and the skip-sample recursive least squares pitch position estimation technique. The former gives only spacings between pitch pulses, while the latter gives registration of the pitch pulses with the speech waveform.
