A Simple Continuous Pitch Estimation Algorithm

Recent work in text to speech synthesis has pointed to the benefit of using a continuous pitch estimate; that is, one that records pitch even when voicing is not present. Such an approach typically requires interpolation. The purpose of this paper is to show that a continuous pitch estimation is available from a combination of otherwise well known techniques. Further, in the case of an autocorrelation based estimate, the continuous requirement negates the need for other heuristics to correct for common errors. An algorithm is suggested, illustrated, and demonstrated using a parametric vocoder.
