How Can I Record Text-To-Speech Output Android has a Text-To-Speech engine called PicoTTS.  

Is there any way to have it read a file and save the output to an audio file (instead of routing the audio to the headset or speakers) without programming a custom app myself?



UPDATE: The OS has a synthesizeToFile() method ... I'm just looking for an app that uses it instead of developing one on my own.
Make sure your default Text-to-Speech engine is PicoTTS (from settings). Install and start a sound recording app (there are many in Play Store). Send it to background and use Speaking Pad.
