Methods and apparatus for altering audio output signals

TL;DR: In this paper, the authors present a system for altering an audio output to sound as if a different person had recorded it when it was played back when the audio data file was sent to the system.

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.
