Many state-of-the-art techniques for estimating glottal closure instants (GCIs) use linear prediction residual (LPR) in one way or another. In this paper, subband analysis of LPR is proposed to estimate the GCIs. A composite signal is derived as the sum of the envelopes of the subband components of the LPR signal. Appropriately chosen peaks of the composite(More)
