    • Abstract
  • Based on wavelet transform, this paper submits a new approach to overlapping speech pitch extraction and tone recognition. Taking advantage of retractility and time-delay characteristics of wavelet, it can detect each pitch in overlapping speech effectively and implement tone recognition by multiscale wavelet transform on overlapping speech. Results of experiment showed the approach is efficient.
