Abstract :
An estimator algorithm for the pitch of voiced speech is presented, based on the following sequence of operations: 1) linear-prediction inverse filtering; 2) short-time spectral analysis by a bank of bandpass filters; 3) envelope extraction on the filter outputs; 4) period determination on the parallel envelopes considered as a multicomponent vector signal, using an algorithm described in a previous work. Results of a comparative evaluation indicate superior immunity to added noise and to bandlimiting with loss of the fundamental component.
