Phonetic recognition using peak weighted binary spectrum
Ki Chui Kim, Hwang Soo Lee, Jung Wan Cho · International Conference on Acoustics, Speech, and Signal Processing · 2003
Invariant acoustic-phonetic features conveyed simultaneously by the stable and the transient portion of the speech signal are investigated quantitatively using a relational cue. To represent the relational cue effectively, a peak-weighted binary spectrum is proposed. Prevocalic nasal recognition results show speaker independence and improved performance in comparison with dynamic time-warping methods.>
