Abstract
To modify the temporal scale of recorded speech, relative stress and relative speaking rate terms are computed for individual sections, or frames, of the speech. These terms are then combined into a single value denoted as audio tension. For a nominal time-scale modification rate, the audio tension is employed to adjust the modification rate of the individual frames of speech in a non-uniform manner, relative to one another. With this approach, compressed speech can be reproduced at a relatively fast rate, while remaining intelligible to the listener.
