Text to Speech with Cloudflare Workers AI
Build a lightning-fast text-to-speech app using Cloudflare Workers AI. Transform any text into natural-sounding audio in milliseconds.
What if you could turn any text into speech instantly? Not just robotic-sounding audio, but natural, human-like voices that bring your words to life.
I built exactly that using Cloudflare Workers AI — a text-to-speech app that converts written words into audio in under 3 seconds, running entirely at the edge of the internet.
How It Works
The app uses a simple but powerful architecture:
Key Features
Smart Input Design — Siri inspired input morphing UI design
Local Storage — All recordings are saved locally with metadata for easy management
{
"id": "b19bace8-5833-435e-8aca-a06760a217fa",
"text": "Your text here",
"latency": 2803,
"createdAt": "2025-10-19T13:54:07.029Z"
