Can the Android API be leveraged to modify the caller's voice during the call?

问题

I can't seem to find any documentation saying this is possible, but Google turned up a few apps that claim to be able to accomplish it.

I'd like to, ideally, be able to play an audio track and have it sent as the caller's voice.

You cannot modify the in-call audio stream, sorry.
