Speechlab offers capable, transparently priced AI dubbing with per-speaker voice cloning and a usable editor, and every step can be bought on its own. Remember that the per-minute price applies to each target language, so multi-language projects add up, and there are no independent reviews to lean on. Its customer and usage figures are its own. A good option for educators and media teams localising regularly; test your language pairs on the free projects first.
What we found
Speechlab is an AI dubbing and localisation platform that transcribes, translates, captions, subtitles and dubs video and audio in more than 50 languages, with each step usable on its own. Its speech-to-speech dubbing can clone each speaker's voice separately or use a native-sounding voice in the target language, keeps or strips background audio, and is refined in a waveform timeline editor with segment-level re-rendering, automatic speaker detection and SRT import; voice cloning availability varies by language pair. It imports common video and audio formats and YouTube links, exports captions as SRT, VTT, TXT or JSON, handles video up to 4K, lets teams share projects for review, and offers a REST API with webhooks and batch tracking. Enterprise customers can add lip-sync, review by native linguists and custom voices. It runs on SOC 2-compliant infrastructure, and its customers include Pearson and DeepLearning.AI, according to the company.
Speechlab, Inc. is based in San Francisco and was incubated at Andrew Ng's AI Fund; press reports date it to 2022 and name Seamus McAteer, its chief executive, and Jayadev Billa as co-founders. Its site shows backing from AI Fund and Grit Capital, and Midwich Ignite says it joined an oversubscribed pre-seed round in 2024; we could not confirm the total raised from a primary source. Speechlab says it has dubbed more than 2.5 million minutes.
Pricing is simple. The free plan gives two dubbing projects with all target languages, voice matching and caption export, with no card required. Pro is pay-as-you-go at $0.60 per minute of source media for each target language, so dubbing a ten-minute video into three languages costs $18, with API access and sharing included. Enterprise pricing is custom, with volume discounts, team roles, custom integrations and invoice billing.
We found no independent reviews. Speechlab suits educators, publishers and media teams localising video into many languages.
