ECMAScript Rocks - EdgeTTS. Who Needs Python?
Introduction
Edge-TTS is one of those fascinating technologies with vague license and questionable legitimacy—yet it just performs. I Presume you've used the Edge-TTS Python package. In that case, you might already understand it taps into Microsoft's Bing Text-to-Speech API—the same API powering read-aloud functionality in Microsoft Edge.
But here's the real kicker: Edge-TTS relies on a TRUSTED_CLIENT_TOKEN floating around in the wild, frankly used in numerous repositories and browser extensions. Who disseminated it? Is it lawful to use? No one is sure yet, yet it works, and that's what matters, providing it's legal. Surely someone would tell it? If not, this is also free regarding translation and making it complete, giving it English text and translating it to another language and making it speak, simple as...

Breaking It Down: How Edge-TTS Works
At its core, Edge-TTS connects to Microsoft's speech synthesis API using WebSockets, sending SSML (Speech Synthesis Markup Language) requests to generate speech dynamically. Here's what makes it tick:
- WebSockets: Establishes a real-time connection to the Bing API.
- Trusted Client Token: The magic key that allows Edge-TTS to function. No one knows who officially issued it, but it's widely used.
- Sec-MS-GEC Header: A SHA-256 hash that ensures timestamp validity.
- SSML Input: This tells the TTS engine which voice to use, pitch, speed, and pauses.
- Audio Stream Output: The API sends back real-time MP3 audio, which plays directly in the browser.
Edge-TTS in the Wild
This isn't just some obscure API locked inside Microsoft Edge. It's available as:
- A Python package (pip install edge-tts).
- A Google Chrome extension that enables text-to-speech on webpages.
- A standalone JavaScript implementation, which we're showing off today.
But… Is It Legal?
Now comes the awkward question: is using Edge-TTS outside of Microsoft Edge legal?
The edge-tts Python package and several browser extensions openly use this API. Although Microsoft has never publicly documented the API for third-party use, it remains accessible.
- No API keys beyond the likely token are needed.
- There are no official rate limits.
- No clear terms of service.
This raises a big question: Does Microsoft allow this, or have they just not caught on? Until they do, it works, so let's use it and do not let them say we have not told you so.
Here It Is, Working in JavaScript!
We've taken Edge-TTS and built a pure JavaScript solution. No Python, no dependencies—just a browser, WebSockets, and JavaScript

/*
(C) 2025 AKADATA LIMITED - 28 Feb 2025 - Andrew Smalley
Based on the Python edge-tts module and Azure EdgeTTS service.
This code demonstrates a JavaScript implementation inspired by the Python edge-tts module.
It connects to the Azure EdgeTTS service via WebSocket, sending properly formatted headers and SSML
to synthesize speech from text. The headers in the requests are critical for proper routing and
processing by the service—do not edit these headers unless you know exactly what you're doing.
How can this be improved?
- Error handling can be further refined for robustness.
- The code could be modularized further by separating concerns (e.g., a separate module for header construction).
- Additional customization of SSML parameters (e.g., voice effects) can be provided.
- Support for additional languages and voices could be integrated.

It works directly in the browser using pure JavaScript—there is no need for Python or external plugins. It connects to the same API, sends SSML requests, and plays audio instantly.
Who needs Python when JavaScript rocks? The mystery of Edge-TTS now not quite unsolved, however one thing is clear: you can get high-quality speech synthesis directly in your browser, and no backend is needed.
Want to take it further? Clone the code, experiment, and tweak the voices. Just be mindful—Microsoft might change the API at any moment. Until then, enjoy the ride!
Here are the voices you can use, and it is as simple as a change to one line
