This is a simple Rust project that implements a Telegram bot integrated with OpenAI. In addition, this project enables customization of OpenAI responses with a Text-to-Speech (TTS) API capable of generating voice messages.

For the TTS functionality, you can use a self-hosted TTS engine, which is demonstrated in my project python-silero-http-api. This project using silero-models, although other TTS services can be used as well.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
sudo apt install libssl-dev
sudo apt install libsqlite3-dev

cargo watch -x run

cargo build --release

Program using SQLite database.

Once the bot is launched for the first time, a database file named 'database.db' will be created. Please add your Telegram username to the list of authorized names in users table (without the first '@' symbol)

Schema:

• users (authorized users)
• chat_history (history messages for GPT conversation)

Setup .env file based on .env.example

GPT_KEY=<OpenAI token>
TELEGRAM_TOKEN=<Bot token>
SENTRY_DSN=<optional sentry dsn>
TTS_PATH=<optional tts path> (example: http://localhost:10000/)

• /help - print help
• /new - start new conversation with new history
• /text - text responses
• /voice - voice responses
