  • Method and system for compensating speech signals using vector quantization codebook adaptation
    Patent number: 5745872
    Abstract: The present invention is a speech processing system and method which includes a codebook generator (26) for generating a reference vector quantization codebook which describes a reference environment and for generating at least one secondary vector quantization codebook which describes at least one secondary environment. The secondary vector quantization codebooks are generated using the reference vector quantization codebook. A speech recognizer (38), which is trained using the reference vector quantization codebook, is also included. A pre-processor (32) accepts as input speech collected from an unknown environment and pre-processes that speech, before input to the speech recognizer (38), using the reference vector quantization codebook and an adaptation of the secondary vector quantization codebooks.
