Crosscorrelation-based multispeaker speech activity detection

  title={Crosscorrelation-based multispeaker speech activity detection},
  author={Kornel Laskowski and Qin Jin and Tanja Schultz},
We propose an algorithm for segmenting multispeaker meeting audio, recorded with personal channel microphones, into speech and non-speech intervals for each microphone’s wearer. An algorithm of this type turns out to be necessary prior to subsequent audio processing because, in spite of close-talking microphones, the channels exhibit a high degree of crosstalk due to unbalanced calibration and small inter-speaker distance. The proposed algorithm is based on the short-time crosscorrelation of… CONTINUE READING
