The app is amazing, but I do have one question about a feature that is not working; voice synthesis. I have uploaded 15 seconds of the preferred voice in the WAV format, but it won't speak and when using the synthesis test it tells me "error saving voice settings." I have tried restarting the app, resizing the file, stopping and starting the pocket tts, and just about everything under the sun. Has anyone else encountered this problem, and or managed to fix it?
