Representing frequencies in speech
نویسندگان
چکیده
Cepstral features derived from power spectrum are widely used for automatic speech recognition. Very little work, if any, has been done in speech research to explore phasebased representations. In this paper, an attempt is made to investigate the use of phase function in the analytic signal of critical-band filtered speech for deriving a representation of frequencies present in the speech signal. Results are presented which show the validity of this approach.
