Computer Models for Speech Signal Representation
A signal may be represented and described in many different ways. Traditionally, the FOURIER resolution of a signal into sinusoidal components has dominated our ideas about analysis and dictated the design of a majority of our measuring equipment. In many cases, however, this approach is inferior to one using base functions directly related to the signal being studied. A best representation for speech signals for example, is one which describes the information in the signal with the fewest possible parameters. This paper will investigate research models of the speech process which provide simple expressions for the spectral waveforms of speech sounds in terms of a set of orthogonal base functions. Synthesized speech based on one of these models will be described.
