Speechlab

Speechlab is an AI dubbing and localization platform for translating spoken video and audio content into other languages while keeping control over the final output. Rather than a fully automated black-box pipeline, it gives users a full editor to review transcripts, translations, and dubbed segments before publishing, including a waveform timeline, speaker detection, and the ability to re-dub individual segments without reprocessing the whole project. It supports more than 50 languages for transcription, translation, captioning, subtitling, and dubbing. A key feature is voice matching: the platform can clone a speaker's original voice or select the closest-matching voice from its library, so dubbed content still sounds like the original speaker instead of a generic narrator. It accepts common video formats (MP4, MOV, MKV) and audio formats (MP3, WAV, M4A), as well as YouTube links, and exports dubbed media, SRT subtitles, or plain transcripts. Speechlab targets media publishers, enterprise marketing and sales teams, corporate training departments, and localization service providers who need to adapt content across languages at scale. It is a web-based platform with credit-based, per-minute pricing: a free tier includes two projects with no card required, a Pro plan is billed per minute of processed media and includes API access, and Enterprise adds volume pricing, white-labeling, and human linguist review. The company's founding year is not stated on the site.
