Speechlab

Speechlab is a speech-to-speech AI platform for video and audio localization and accessibility. It turns 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. It is a globally distributed team of researchers, engineers, and product designers who align with a set of values that define its approach to work.

The platform emphasizes an editorial layer between AI generation and publish-ready output, enabling teams to localize content and make it accessible to global audiences.

Speechlab supports workflows that let users review and refine every word before it ships, with tools spanning transcription, translation, captioning, subtitling, and dubbing.
