Temporal information processing in speech perception.
For a set of formal rules for the phonetic interpretation of speech during its perception one should have data concerning a possible structure and parameters of a subjective mechanism for processing temporal information, from segmenting the speech signal to making phonetic decisions. At present such data cannot be found in the literature. An attempt has been made to find out more about some parts of the subjective mechanism of duration measurement and comparison by studying the perception of tempo changes in short sound sequences. Running or 'momentary' tempo is shown to be the feature of tempo change perception, and possible procedures for its detection have been tested. A computational technique for getting the quantitative parameters of the mechanism is briefly described.
