Abstract
Official abstract text for this publication.
A hybrid instantaneous/differential encoding technique is described herein that may be used to reduce the bit rate required to encode a pitch period associated with a segment of a speech signal in a manner that will result in relatively little or no degradation of a decoded speech signal generated using the encoded pitch period. The hybrid instantaneous/differential encoding technique is advantageously applicable to any speech codec that encodes a pitch period associated with a segment of a speech signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for encoding an audio signal comprising a series of temporally ordered segments, comprising: determining, using a processing unit or an integrated circuit, if instantaneous coding or differential coding should be applied to encode a pitch period associated with a current segment of the audio signal by determining if a number of bits required to differentially encode a magnitude of a difference between the pitch period associated with the current se…
