What is Speechlab?
Speechlab is an AI dubbing and translation platform that enables users to transcribe, translate, caption, subtitle, and dub video and audio content in 50+ languages. Unlike black-box AI tools, Speechlab provides a full professional editor that gives users complete control to review and refine every word before shipping their localized content. The platform uses speech-to-speech AI technology to capture thought and emotion with the nuance of the human voice, bridging language barriers to make content globally accessible.
Key features include advanced transcript and translation editing with SRT import, segment operations, audio waveform editing, and automatic speaker detection. The platform offers hyper-realistic voice matching that can replicate the original speaker's voice in a new language or replace it with an authentic native voice. Segment-level dub regeneration allows users to re-dub only changed segments rather than entire projects, saving credits. Enterprise features include API integration, bulk processing for hundreds of files, and white-glove human-in-the-loop review by native linguists.
Speechlab is built for media publishers and creators dubbing documentaries, podcasts, YouTube content, audiobooks, and films. It also serves enterprise marketing and sales teams localizing product demos and brand content across markets, corporate training and L&D teams dubbing training modules and course libraries, and localization service providers who plug into existing workflows via API. The platform supports multi-speaker content with real multi-speaker support and voice cloning that preserves the original speaker's identity.
The workflow includes uploading files (drag-and-drop, YouTube link, or bulk-import), transcribing with diarized transcripts and speaker labels, generating captions, translating segment by segment, creating frame-accurate SRT subtitles, assigning voices per speaker to render dubbed audio, and exporting dubbed video, audio, subtitles, or translation text. Every capability works independently or flows into the next, allowing users to start and stop anywhere.
