​
Common Steps

​
1. Create a Virtual Environment

To ensure your Python environment is isolated, create a virtual environment: 
python3 -m venv venv
Activate the virtual environment:
  • On Linux/Mac: 
    source venv/bin/activate
  • On Windows: 
    venv\Scripts\activate

​
2. Install Requirements

Once the virtual environment is activated, install the required dependencies: 
pip install -r requirements.txt

​
3. Sign in and Create a New Project on Livekit

Sign in here: Livekit Cloud After signing in, create a new project and copy the following tokens: 
LIVEKIT_API_KEY
LIVEKIT_API_SECRET
LIVEKIT_URL

​
4. Create a .env File

Create a .env file in the project root directory. This file should contain the following keys with appropriate values: 
LIVEKIT_API_KEY=...
LIVEKIT_API_SECRET=...
LIVEKIT_URL=...
OPENAI_API_KEY=...
DEEPGRAM_API_KEY=...
SMALLEST_API_KEY=...

​
5. Install the Plugin

To set up the Livekit plugin for smallest.ai, run the following commands: 
chmod +x install_plugin.sh
./install_plugin.sh

​
Usage

​
1. Running generate_audio.py

To generate audio using the Smallest AI plugin as a WAV file, run the following command: 
python3 generate_audio.py
You can change the parameters in the script and try out different voices, languages, and texts.

​
2. Running minimal_assistant.py

To build a minimal Livekit voice assistant using the Smallest model, run the following command: 
python3 minimal_assistant.py dev
