Advantages of wideband over narrowband channels for speaker verification employing MFCCs and LFCCs
Wideband communications permit the transmission of an extended frequency range compared to the traditional narrowband. While benefits for automatic speaker recognition can be expected, the extent of the contribution of the additional bandwidth in wideband is still unclear. This work compares the i-vector speaker verification performances employing speech signals of 0-4 kHz, 4-8 kHz, and 0-8 kHz and different sets of cepstral features extracted using linearlyand a mel-spaced filterbanks....[Show more]
