About SpeechLab
FreemiumIntermediateAPI availableWeb · API
Speechlab is an AI-powered platform for transcribing, translating, captioning, subtitling, and dubbing video and audio content in 50+ languages. Unlike black-box tools that produce output you cannot refine, Speechlab provides a full editor with waveform timeline, per-segment text and timing adjustments, and speaker detection. It is designed for media publishers, enterprise marketing teams, corporate L&D departments, and localization service providers who need professional-grade output. Workflows support multi-speaker content, voice cloning that preserves the original speaker's identity, and native voice replacements. The platform works standalone per capability (e.g., transcription only) or as an end-to-end pipeline: upload → transcribe → translate → caption/subtitle → dub → export. Export options include dubbed video/audio, SRT/VTT subtitles, and plain-text transcripts. Speechlab differentiates itself with segment-level dub regeneration (change one word, re-dub only that segment), hyper-realistic voice matching, enterprise features like bulk processing, API integration, and human-in-the-loop review by native linguists. It is SOC 2 compliant and incubated at Andrew Ng’s AI Fund.
Behind the Verdict
Speechlab stands out in the AI dubbing space because it prioritizes editorial control over pure automation. The waveform timeline editor with per-segment text and timing adjustments means you can fix a mistranslation or adjust a subtitle without redoing the entire project. The segment-level dub regeneration is a standout feature: change one word in the translation and only that segment gets re-dubbed, saving credits and time. Voice cloning is another strong point — you can preserve the original speaker's voice across languages, or switch to a native voice for authenticity. For enterprise teams, Speechlab offers bulk processing, API integration, and role-based access, making it scalable for large libraries. The platform is SOC 2 compliant, which is crucial for regulated industries. However, the free tier is limited to two projects, and the Pro pricing at $0.6 per minute per language can become expensive for longer content, especially if multiple target languages are needed. Also, voice cloning availability varies by language pair, and there's no live streaming or real-time dubbing support. Compared to alternatives like HeyGen or Dubverse, Speechlab offers deeper editing capabilities but may have a steeper learning curve. For teams that prioritize output quality and control, Speechlab is a strong choice.

Where the pricing makes sense
The company stage and team size where SpeechLab's pricing actually pencils out — and where peers do it cheaper.
Speechlab's per-minute pricing ($0.6/min/language) suits teams with moderate volume who value control over cost. For high volume, negotiate volume discounts on Enterprise. Compared to HeyGen (per-minute or subscription) or Dubverse, Speechlab's editor gives more control but may cost more for short projects. Larger enterprises should compare total cost including review services.
Setup time & first value
How long it actually takes to get something useful out of SpeechLab — broken out by persona, not the marketing-page minute.
For individuals, first value in minutes: upload a video, transcribe, translate, and generate a dub in under 30 minutes for short clips. Teams with API integration can set up automated pipelines in a few hours. Enterprise onboarding including custom voice training may take 1-3 days.
Switching to or from SpeechLab

Migrating in

Migrating out
- ↗To another AI dubbing platform: Export your project's SRT subtitles and dubbed audio/video from Speechlab to upload elsewhere.
