llm_convo

Use ChatGPT over Twilio to create an AI phone agent (works for incoming or outgoing calls).

How it works

Twilio Webhook -> Flask app -> Twilio Media Stream (websocket) -> Whisper -> ChatGPT API -> Google TTS -> Twilio Play Audio

Setup

  1. pip install git+https://github.com/sshh12/llm_convo
  2. Environment Variables
OPENAI_API_KEY=
TWILIO_ACCOUNT_SID=
TWILIO_AUTH_TOKEN=
TWILIO_PHONE_NUMBER=

Demo

Basic Text Chat

Try python examples\keyboard_chat_with_gpt.py to chat with GPT through terminal.

Twilio Helpline

Try python examples\twilio_ngrok_ml_rhyme_hotline.py --preload_whisper --start_ngrok. This requires whisper installed locally.

This will create an ngrok tunnel and provide a webhook URL to point to in Twilio settings for a purchased phone number.

Twilio Pizza Order

Try python examples\twilio_ngrok_pizza_order.py --preload_whisper --start_ngrok --phone_number "+1..........". This requires whisper installed locally.

This will create an ngrok tunnel and provide a webhook URL to point to in Twilio settings for a purchased phone number. Once the webhook is updated, it will start an outgoing call to the provided phone number.

Code Snippets

Setup a Haiku hotline with Twilio that can be called like any other phone number.
