Voicesmith

Free real-time voice changer and Altered Auditory Feedback (DAF + FAF) app

Voicesmith app records an audio signal from the built-in microphone, processes it in some way and plays it back through the earphones in real-time. You need to plug in wired earphones or connect the Bluetooth headset to hear the sound.

IMPORTANT! If the app crashes on your smartphone, please be nice -- write me an email and describe what happens. Some of the Android OS releases and smartphone hardwares have their specific nuances. I can only help you, if I receive a detailed error report from you (see below). Just giving a bad rating is useless!

There are some of the classical Phase Vocoder effects available. Raise or lower your voice pitch up to 12 semitones, make it sound like a robot, make it detuned or hoarse. Feel free to experiment with this app. Just try to alter your own voice or of somebody else.

Voicesmith can also be used to perform the Delayed Auditory Feedback (DAF) and Frequency-Shifted Auditory Feedback (FAF). The altered auditory feedback is successfully applied in stuttering therapy, to help people speak more fluently. Please ask your therapist to find out more.

You should also know:

* The lowest possible feedback delay can vary from smartphone to smartphone.

* The lowest possible delay on Android based smartphones is unfortunately bigger than on special hardware devices.

* You could also try to switch the default sample rate to 22050 Hz or 11025 Hz in order to reduce CPU usage.

* This software is provided "as is", without warranty of any kind.
