Abstract:
A new tool for speech analysis is presented, operating in real-time and incorporating the analysing power of a contemporary auditory model to produce the familiar display of the speech spectrograph. This "auditory spectrograph" is used to analyse English consonant sounds and the results are compared with conventional wide and narrow band spectrograms. The auditory analyses are found to attach more visual weight to the acoustic cues associated with speech production and perception, and features that are either difficult or impossible to distinguish on conventional spectrograms are clarified.
