Twitch Chat TTS Bot (Offline / Edge-TTS)

Have a local TTS service read your Twitch Chat for you!
Reads all chat messages except your own and speaks them aloud using Edge-TTS (modern neural voices) or espeak-ng (retro, robot-like vibes).
You can toggle between these two by setting the flag USE_EDGE_TTS = True in the script.

Manual Prerequisites

This project relies on Python 3.8+ and the following things:

• Edge-TTS (uses Microsoft Edge neural voices, requires edge-tts Python package and ffmpeg for audio playback), or
• espeak-ng (classic, lightweight, robotic TTS engine available locally on most platforms).
• Go to Twitch Token Generator to get your client secret and client ID.

---

Installing Python

Make sure Python 3.8 or newer is installed on your system:

• Download Python
• Verify installation with:

python --version

---

Installing Edge-TTS (Might as well install everything else)

pip install twitchio requests edge-tts pycaw comtypes

• REQUIRED: Install FFMPEG to play audio output

  • Download from https://ffmpeg.org/download.html
  • Follow platform-specific installation instructions to add ffmpeg to your system PATH.

---

Installing espeak-ng

• Windows:

  • Download installer from https://github.com/espeak-ng/espeak-ng/releases (look for .exe installer)
  • Install and add to PATH if needed.

• Linux (Debian/Ubuntu):

Configuration

• USE_EDGE_TTS: Set to True to use Edge-TTS (modern neural voices). Set to False to use espeak-ng (retro, robotic voices).
• CHANNEL: Set this to your Twitch channel name.

---

Notes

• Ensure that ffmpeg is installed and accessible in your system's PATH if using Edge-TTS.
• If using espeak-ng, you can adjust the voice and language settings by modifying the espeak-ng command options in the script.
• This bot uses the Twitch IRC chat interface to read messages. Ensure your Twitch account has the necessary permissions to read chat messages.
