Abstract :
By analyzing a new model for short-time complex cepstrum of voiced speech, this paper proposes a new method for homomorphic deconvolution to recover the vocal tract impulse response; The experimental results are given and the effects of pitch period on the recovery of vocal tract impulse response are discussed in the paper.
