Frequency-related Repres
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 phase-based 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.

متن کاملEffect of Changing Technology on Hospital Costs
For many years the hospital industry has been introducing new and improved medical services. The introduction of these services has been responsible for a large part of the increase in hospital care costs. Such services arise largely from the availability of the new medical technology, procedures, and techniques. A simple example is the use of new and expensive drugs and medications. A more dra...
