Systems and methods for implementing segmentation in speech recognition systems

摘要

A speech recognition system ( 105 ) includes an acoustic front end ( 115 ) and a processing unit ( 125 ). The acoustic front end ( 115 ) receives frames of acoustic data and determines cepstral coefficients for each of the received frames. The processing unit ( 125 ) determines a number of peaks in the cepstral coefficients for each of the received frames of acoustic data and compares the peaks in the cepstral coefficients of a first one of the received frames with the peaks in the cepstral coefficients of at least a second one of the received frames. The processing unit ( 125 ) then segments the received frames of acoustic data based on the comparison.
