How AI localization and dubbing works with Speechlab

Every capability works on its own — or flows into the next. Start anywhere. Stop anywhere. Pick up where you left off. All of it works on spoken content: video, audio, podcasts, audiobooks.

Upload. Drag and drop a file, paste a YouTube link, or bulk-import your content, for video, audio, podcasts, audiobooks.

Transcribe. ASR produces a diarized transcript with timestamps and speaker labels. Edit inline.

Caption. Generate captions from the transcription. Speaker-labeled, editable, and accessibility-ready.

Translate. Select a target language. AI translates the spoken content segment by segment. Edit every line.

Subtitle. Create SRT subtitles from the translation. Frame-accurate, validated, broadcast-ready.

Generate dub.
Assign a voice per speaker then render the dubbed audio. Preview in the editor alongside the source.

Export.
Dubbed video, dubbed audio, SRT subtitles, translation text — whatever the deliverable needs.

Frequently asked questions

What is Speechlab?
Speechlab is an AI dubbing and translation platform that lets you transcribe, translate, caption, subtitle, and dub video and audio in 50+ languages. Unlike black-box tools, Speechlab gives you a full editor — so you can review and refine every word before it ships.

What file formats does Speechlab support?
Video (MP4, MOV, MKV, WebM), audio (MP3, WAV, M4A, FLAC), and direct YouTube link import. Export options include dubbed video, dubbed audio, SRT/VTT subtitles, and plain-text transcripts.

How many languages does Speechlab support?
50+ languages for transcription, translation, and dubbing — including major European, Asian, Middle Eastern, and African languages. Each language has native-voice options; voice cloning availability varies by language pair.

Can I clone the original speaker's voice in another language?
Yes. Source-clone mode captures the original speaker's voice characteristics and synthesizes them in the target language. For multi-speaker content, each speaker can be cloned independently.

What if I only need transcription or subtitles, not dubbing?
Every product works standalone. You can use Speechlab purely for transcription, captions, or SRT export without ever generating a dub. You only pay for what you use.

How does pricing work?
Credit-based, per-minute pricing. Each language you add costs credits based on the source media duration. Start with 2 free projects, no card required.

Can I edit the output after it's generated?
Yes. Speechlab includes a waveform timeline editor with per-segment text editing, timing adjustment, and segment-level re-rendering. Change one sentence without re-processing the whole file.

Does Speechlab offer an API?
Yes. Pro and Enterprise plans include RESTful API access with per-project endpoints, webhook callbacks, and batch job tracking. Integrate Speechlab into your existing media asset management or translation management pipeline.

What enterprise features are available?
Enterprise accounts include bulk processing, API integration, linguist-reviewed outputs, custom voice creation, role-based team access, invoice billing, and lip-sync.
