How to make a voice changing app?

**zf4021** · 08-31-2011, 03:21 AM

I am a Blackberry developer fresher. And really want to make a tiny voice changing app for my girl to make her laugh. But I found seems the Blackberry OS do not have that API, and I only could make the phone record and repeat what I say, but could not change my voice to a funny style.

Could any professor help me? Is there good way or idea or code?

With all my sincere thanks!!!
