DiscordNPC

DiscordNPC lets you interact with ChatGPT through a Discord voice channel, enabling a natural conversation.

Entirely stateless, and the bot will start a new conversation when it is removed from the call and placed back in.

It also includes a simple Discord command for asking questions.

Powered by google-speech, acheong08/ChatGPT, and py-cord.

Issues

There are many sources of latency, mainly the ChatGPT "API" and the AssemblyAI real-time transcription API. This leads to some long waiting times, but it works.

Additionally, ChatGPT has very low rate limits and will return a 429 error if you send too many requests. This is not handled by the bot, so you will have to wait for the rate limit to reset.

I implemented a rate limiter in the bot, but it is not very effective. It just says "I lost my train of thought. Give me a minute to get back on track..." right now.

Installation

All manual baby! This project is a proof of content and does not currently include a Dockerfile.

Install with poetry install --no-root --without dev and you will be good to go.

Some project dependencies have native dependencies:

• SoX
  • Debian package: sox
  • MacOS brew: brew install sox
  • Windows download: https://sourceforge.net/projects/sox/files/sox/14.4.2/
• SoX MP3 Support
  • Debian package: libsox-fmt-mp3
  • MacOS brew: brew install sox --with-lame
  • It is hard to find Windows DLLs, so I included a /bin folder in the repository with the DLLs I found to work.
• ffmpeg

Configuration

Environment Variables

• CHATGPT_*: Configuration for acheong08/ChatGPT. Arguments are analogous to the config.json format defined in this wiki page for the ChatGPT python wrapper.
  • i.e.: CHATGPT_SESSION_TOKEN is analogous to session_token in the config.json file.
• DNPC_TOKEN: Discord bot token. Can be created in the Discord Developer Portal.
• DNPC_WEBHOOK: Discord webhook to log with. Designed for "production" use, not required.
• DNPC_ASSEMBLY_TOKEN: AssemblyAI token for speech-to-text. Required for speech-to-text functionality. Can be obtained on the app dashboard.
  • You'll need to have a paid account to use the real-time transcription.
  • If you know an alternative to AssemblyAI that is free, tell me on Discord: @regulad#7959

Execution

After setting the required environment variables, run poetry run python -m discordnpc to start the bot.

Usage
