By 2024, a dozen tools could auto-dub a video in minutes. The output was fast, but it wasn't good enough to ship. Voices sounded synthetic. Speech-to-speech output missed tone, timing, and context.

Speechlab’s mission is to bridge language barriers by creating speech technologies that convey thought and emotion with the nuance and versatility of the human voice. We didn't just build another render queue. We built the editorial layer that was missing between "AI-generated" and "ready to publish" — so teams can localize their video and audio content and make it accessible to global audiences.

Speechlab is a speech-to-speech AI platform for video and audio localization and accessibility. We turn spoken content into localized, accessible media — dubbed audio, translated captions, subtitles — in 50+ languages, with a full editing suite so you control every step.

Speechlab was incubated at Andrew Ng’s AI Fund and is backed by leading investors. We are a globally distributed team of researchers, engineers, and product designers who align with a set of values that define our approach to our work.
