Abstract
The disclosed method and apparatus controls the rate of playback of audio data corresponding to a stream of speech. Using speech recognition, the rate of speech of the audio data is determined. The determined rate of speech is compared to a target rate. Based on the comparison, the playback rate is adjusted, i.e. increased or decreased, to match the target rate.
Claims24
A method for controlling rate of playback of audio data corresponding to a stream of speech, comprising the computer implemented steps of:
- using speech recognition, calculating rate of speech in the stream of speech;
- receiving the calculated rate of speech at a playback rate adjustment unit;
- using the playback rate adjustment unit, determining difference between the calculated rate of speech and a target playback rate;
- and
- based on said determining adjusting rate at which the audio data is played back to match the target playback rate.
Apparatus for controlling rate of playback of audio-data corresponding to a stream of speech, comprising
- a calculation unit for calculating rate of speech in the stream of speech using speech recognition;
- and
- a playback rate adjustment unit coupled to receive from the calculation unit the calculated rate of speech, the playback rate adjustment unit determining difference between the calculated rate of speech and a target playback rate, and based on said determined difference, the playback rate adjustment unit, adjusting rate at which the audio data is played back to match the target playback rate.
