AN ADAPTIVE EQUALIZER FOR A CODED SPEECH SIGNAL

摘要

A speech communication system provides a speech encoder [100] that generates a set of coded parameters representative of the desired speech signal characteristics. The speech communication system also provides a speech decoder [200] that receives the set of coded parameters to generate reconstructed speech. The speech decoder includes an equalizer [204] that computes a matching set of parameters from the reconstructed speech [301] generated by the speech decoder [200], undoes the set of characteristics corresponding to the computed set of parameters, and imposes the set of characteristics corresponding to the coded set of parameters, thereby producing equalized reconstructed speech [306].
