Closed - This job posting has been filled.

Job Description

I have an Android app that allows calling through VOIP. It is finished, however, it is supposed to manipulate the user's voice into a range of different voices. The coder has only been able to manipulate the pitch. I need a coder who is able to manipulator a user's voice by more than just pitch, so that the voice can become the following:
