Abstract
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.
Claims9
A method of recognizing patterns in acoustic data, comprising:
- receiving frames of acoustic data;
- determining first cepstral coefficients corresponding to the received frames of acoustic data;
- determining second cepstral coefficients corresponding to the received frames of acoustic data;
- determining a first number of peaks in the first cepstral coefficients and a second number of peaks in the second cepstral coefficients;
- determining at least one weighting parameter based on the determined second number of peaks;
- and
- recognizing patterns in the received frames of acoustic data using the at least one weighting parameter.
A speech recognition system, comprising:
- means for receiving frames of acoustic data;
- means for determining a first number of peaks of cepstral coefficients corresponding to the received frames of acoustic data;
- means for determining a second number of peaks of cepstral coefficients corresponding to the received frames of acoustic data;
- means for determining at least one weighting parameter based on the determined second number of peaks;
- and
- means for recognizing patterns in the frames of acoustic data using the at least one weighting parameter.
