The use of phase-only representations of speech for isolated word recognition is explored. Until recently the ear was thought to be short-term phase insensitive. However, short-term phase-only reconstructed speech has been shown to retain much of the intelligibility of the original signal. Using cepstral and analytic signal processing techniques, a system for isolated word recognition is developed. The results of tests for both the speaker dependent and speaker-independent case indicate that phase may be an important feature to consider in the development of word recognition systems. Author
