  • Project: An Investigation of Morphvox Pro Voice Changer

Camilla's project aimed to determine the effects that the different features of Morphvox Pro voice changer software had on the voice, and then to see if it was possible to detect the use of the software in an output sound file.

The conclusion of Camilla's work was that whilst Morphvox pro voice changer software can reliably change the gender of a voice in terms of the vowel formants and pitch, the use of the software is detectable due to irregularities that appear in the waveform that would not occur in natural speech.
