A small tool that redirect tts output to audio input. Based on edge-tts.

Prerequisites

You will need some audio cable device to do the redirection. I test it on Virtual Audio Cable. But I suppose it would work on other choices.

I tested it on python 3.11 and it works. It does not seem to work with 3.8. Anywhere between them is untested.

Usage

If you are using a different audio cable device, you may need to change the device name in utils.py.

Just run python main.py and it will start accept tts input. Set your voice chat application input to audio cable output and it's done.

Known issues

1. It seems not all audio API is usable. WASAPI complains about sample rate but DirectSound is OK.
2. There's significant delay between tts input and audio output.
