| 摘要 |
A method and apparatus for robust speech activity detection is disclosed. The method may include calculating autocorrelations by filtering input signals using order statistic filtering, averaging the autocorrelations over a time period, obtaining a voiced speech feature from the averaged autocorrelations, classifying the input signal as one of speech and non-speech based on the obtained voiced speech feature, and outputting only the classified speech signals or the input signals along with the speech/non-speech classification information, to an automated speech recognizer.
