Abstract:
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 configured to modify a spectral tilt of the input signal, based on a spectral tilt associated with at least one of the one or more spectral shapes supported by the encoder device, to generate the processed signal; and where the speech enhancement processor is configured to modify the spectral tilt of the input signal in response to a determination that an input noise tilt of the input signal surpasses a maximum tilt limitation that is based on one or more spectral shapes available at the encoder device.
