Abstract: Methods, systems and computer readable media for altering an audio output are provided. In some embodiments, the system may change the original frequency content of an audio data file to a second frequency content so that a recorded audio track will sound as if a different person had recorded it when it is played back. In other embodiments, the system may receive an audio data file and a voice signature, and it may apply the voice signature to the audio data file to alter the audio output of the audio data file. In that instance, the audio data file may be a textual representation of a recorded audio data file.

Audible electronic exercise monitor
Arthur H. Kaufman
- 26 Jun 2001
TL;DR: In this article, an electronic activity monitor for monitoring the performance of an activity such as an exercise comprises an activity detector responsive to motion associated with the activity to output a corresponding signal, a processor for receiving the signal and determining a starting address at which a block of corresponding sound data is stored, a memory for storing sound data corresponding to a plurality of values associated with monitored activity, the sound data preferably comprising data representing a voice representation of the values, and a speech generator for generating a naturally sounding human voice or reproducing a pre-stored version of an actual human voice.
