摘要Abstract: Abstract—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 letter
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.
