Abstract
Official abstract text for this publication.
A speech enhancement system enhances transitions between speech and non-speech segments. The system includes a background noise estimator that approximates the magnitude of a background noise of an input signal that includes a speech and a non-speech segment. A slave processor is programmed to perform the specialized task of modifying a spectral tilt of the input signal to match a plurality of expected spectral shapes selected by a Codec.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a speech enhancement processor configured to receive an input signal and output a processed signal; and an encoder device coupled with the speech enhancement processor and configured to receive the processed signal from the speech enhancement processor, where the encoder device supports one or more spectral shapes to encode the processed signal for transmission over a communication channel; where the speech enhancement processor is…
