Why do some stream translation tools only work on Chrome?

Tools like VOXO and Stream CC use Chrome's built-in Web Speech API for free speech recognition, which locks them to Chrome.

Which stream translation tool works on any browser?

StreamTranslate works on Chrome, Firefox, Edge, Safari, and any modern browser because it processes speech in the cloud via Deepgram.

Does Chrome-only mean worse accuracy?

Yes. Chrome's Web Speech API is general-purpose, not purpose-built for streaming. Dedicated cloud APIs like Deepgram Nova-2 are significantly more accurate.

Why Chrome-Only Stream Translation Is a Problem

Tools like VOXO and Stream CC are locked to Chrome. Here is why that is a problem — and what to use instead.

Why Are Some Stream Translation Tools Chrome-Only?

Several stream translation tools — VOXO.live, Stream CC — display a warning: "This service only works on PC Chrome browser." These tools use Chrome Web Speech API, a browser feature built by Google that provides free speech recognition. Because it is tied to Chrome, these tools are permanently locked to that browser.

The Real Problems with Chrome-Only Translation

Mac users on Safari: Cannot use Chrome-only tools. A significant portion of streamers — especially VTubers — use Macs.
Firefox users: Second most popular desktop browser globally. Chrome-only tools do not work.
Edge users: Even though Edge is Chromium-based, Web Speech API implementation may differ.
Linux streamers: Often use Firefox or custom browsers. Chrome-only tools fail.
Google API dependency: If Google limits the Web Speech API, Chrome-only tools break.
Accuracy ceiling: Web Speech API was built for dictation, not streaming with gaming audio and accents.

The Alternative: Cloud-Based Speech Recognition

StreamTranslate sends audio to Deepgram Nova-2 in the cloud. Transcription happens server-side, and the result is delivered back to your OBS browser source as subtitles.

Because there is no browser API involved, StreamTranslate works identically on Chrome, Firefox, Edge, Safari, and any browser. The browser is just a display layer.
