ENHANCEMENT OF TEMPORAL INFORMATION

摘要

A Method of operating an audio processing device To Improve a user's perception tospeech sound, The method comprising: Splitting an audio signal into a plurality of frequency bands, applying amplitude modulation for said frequency bands with a rate of modulation that Is differ corresponding to the frequencies at which peaks of acoustic energy occur In speech wave (e.g. Formants) or constant for each frequency band; in a way that lower amplitude part of modulation lie below threshold of hearing.
