Speech Translator

Speech Translator is a Chrome extension for real-time transcription and translation of spoken content from almost any source in your browser. It listens to audio from a browser tab, your desktop or a microphone, converts speech to text with recognition powered by Google or Microsoft, and then translates that text using the translation service you prefer. The result appears as captions and transcripts you can read, save or broadcast.

The extension is designed for people who work with spoken content across languages. Livestreamers use the compact subtitle view as an OBS overlay so viewers can follow along; language learners dictate their own speech and read the translation to practise pronunciation; meeting and call participants capture transcripts for later reference; and people with hearing impairments get readable captions. Version 1.1 added a profanity filter with multi-language dictionaries, read-aloud for microphone input, enterprise and education provisioning, and automatic language detection inside a transcript.

The core experience is free with no registration and runs locally in the browser or through secure Google APIs. Premium upgrades unlock advanced options such as desktop capture, offline speech recognition and premium translation engines. It supports 21 interface languages, has over 100,000 users and is rated around 3.9 out of 5 by more than 400 reviewers on the Chrome Web Store.
