Post Description

Cloudflare's recent voice agents release provides a free daily tier for Deepgram STT, TTS use.

So I created a Voice AI Agent pipeline that runs on Cloudflare workers with Durable Objects and it interfaces with an Arduino ESP32. This lets you bring any LLM to power your Voice AI Toys and Desk companions with STT + TTS handled natively.
