ElevenLabs lets you build high-quality realtime voice agents and bring your custom voices to Elato. To use ElevenLabs on your ESP32, set your ELEVENLABS_API_KEY in the .env file in your Deno server. When bringing a character from Eleven Labs, add a character name and Agent Id (with prefix agent_*) from Eleven Labs’ Agents Platform. Head to Create > + Eleven Labs Agent: Eleven Labs Create
Make sure your TTS output frequency is 24KHz in the Voice tab of your newly created agent’s dashboard. This will match with the output frequency your ESP32 expects.
