With the exception of relatively sophisticated methods such as cepstrum analysis, the problem of reliable pitch-period extraction has remained largely unsolved. This paper examines the feasibility of pitch-period extraction by means of the nonstationary error process resulting from adaptive-predictive quantization of speech. A real-time hard-ware system that may be realized at low cost is described.
