Patent ID: 8249861

Claim:
A speech system that improves the intelligibility and quality of a processed speech, comprising: a first spectral compressor that compresses a first pre-selected high frequency band and maps the first compressed high frequency band to a first band limited lower frequency range; an acoustic echo canceller coupled with an output of the first spectral compressor to receive a first sound signal modified by the first spectral compressor, where the acoustic echo canceller dampens repetitive sounds in the first sound signal created by a reflection from a surface; and a second spectral compressor coupled with an output of the acoustic echo canceller to receive a second sound signal modified by the acoustic echo canceller, where the second spectral compressor compresses a second pre-selected high frequency band of the second sound signal and maps the second compressed high frequency band to a second lower band limited frequency range, and where the second spectral compressor comprises circuitry or a computer-readable storage medium that stores instructions executable by a processor.
