Hacky Steam Chat -> Discord Voice channel TTS Bot

This works if you are me or have a fair bit of know-how.

Requirements

• .NET 10 SDK (Windows, x64)
• A Discord bot account with a valid token
• A Steam account for message bridging
• ffmpeg (for Coqui TTS audio conversion, optional)
• Native dependencies for NetCord voice support (DAVE protocol): libdave.dll, opus.dll, libopus.dll, libsodium.dll — see NetCord: Installing Native Dependencies

Setup

1. Rename App.config.example to App.config
2. Edit the values within:
   • BotToken — your Discord bot token
   • SteamUser / SteamPass — Steam credentials (required for Steam→Discord TTS bridge)
   • TTS engine settings (optional, for Coqui TTS)
3. Build and run:

dotnet build
dotnet run
