Determination of instants of significant excitation in speech using group delay function

  title={Determination of instants of significant excitation in speech using group delay function},
  author={R. Smits and Bayya Yegnanarayana},
  journal={IEEE Trans. Speech and Audio Processing},
A new method for determining the instants of significant excitation in speech signals is proposed. Here, significant excitation refers primarily to the instant of glottal closure within a pitch period in voiced speech. The method is based on the global phase characteristics of minimum phase signals. The average slope of the unwrapped phase of the short-time Fourier transform of linear prediction residual is calculated as a function of time. Instants where the phase slope function makes a… CONTINUE READING
