| Summary: | The perceptual consequence of change in parameters of vocoded speech for various reverberation
conditions has been examined. The three controlled variables were: number of
bands, instantaneous frequency changes rate and reverberation conditions. The effects were
quantified in terms of: (a) non-words’ recognition scores for young normal-hearing listeners,
(b) “ease of listening” based on the time of reaction (response delay) and (c) the subjective
measure of difficulty (ten-degree scale). The results have shown that the fine structure information
is a relevant cue in speech perception in reverberation conditions. It has also been
observed that only the slow variations of instantaneous frequency are critical in perception.
A good correlation between all subjective measures considered was found in this study. |
