Abstract
Distant sample or pitch prediction is an important aspect in predictive speech coders. The pitch predictor greatly enhances the efficiency of these coders by regenerating the periodicity in the decoded speech. This paper provides a review of the research done in pitch prediction. The significant issues considered are filter formulation, determination of the pitch parameters, stability, implementation as part of a speech coder and bit rate for transmission of the pitch parameters
