An alternative front-end for the AT&T WATSON LV-CSR system


In previously published work, we have proposed a novel feature extraction algorithm, based on the Teager-Kaiser energy estimates, that approximates human auditory characteristics and that is more robust to sub-band noise than the mean-square estimates of standard MFCCs. We refer to the novel features as Teager energy cepstrum coefficients (TECC). Herein, we… (More)
