Altered Auditory Feedback
Mumble Melody is an application that leverages Altered Auditory Feedback (AAF). During AAF, a person's speech is altered in near-real time. Mumble Melody modulates the user's voice and plays it back to them while they are speaking. Included are Unaltered (raw voice), Whisper (voiceless sound), Reverb (cathedral sound), and Harmonized (robotic sound) voice transformations.
