Abstract
Official abstract text for this publication.
System and method embodiments for dual modes pitch coding are provided. The system and method embodiments are configured to adaptively code pitch lags of a voiced speech signal using one of two pitch coding modes according to a pitch length, stability, or both. The two pitch coding modes include a first pitch coding mode with relatively high precision and reduced dynamic range, and a second pitch coding mode with relatively large dynamic range and reduced precision. The first pitch coding mode is used upon determining that the voiced speech signal has a relatively short or substantially stable pitch. The second pitch coding mode is used upon determining that the voiced speech signal has a relatively long or less stable pitch or is a substantially noisy signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for dual modes pitch coding implemented by an apparatus for speech/audio coding, the method comprising: coding pitch lags of a plurality of subframes of a frame of a voiced speech signal using one of two pitch coding modes according to a pitch length, stability, or both, wherein the two pitch coding modes include a first pitch coding mode with relatively high pitch precision and reduced dynamic range and a second pitch coding mode with relatively hi…
