Speech-to-text and voice AI provider offering real-time transcription and live captioning APIs.
DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.

It supports features such as multi-speaker handling and broad language coverage, and the company emphasizes security and compliance certifications. Speechmatics is aimed at developers, product teams, media organizations, and enterprises that need to add accurate transcription, subtitles, or live captions to their own workflows and applications rather than use a packaged consumer note-taker.
