Each tool is a single step. When you need the whole pipeline — transcribe, translate, dub, check, publish — the [platform pages](https://www.vitra.ai/platform) cover how those steps chain together, and [agentic workflows](https://www.vitra.ai/features/agentic-workflows) covers how to automate them. Working with whole assets rather than single files? Start from [video dubbing](https://www.vitra.ai/features/video-dubbing), [document translation](https://www.vitra.ai/features/document-translation), or [website translation](https://www.vitra.ai/features/website-translation). FAQ ## Questions people ask How many voices and languages are available? + Over 12,000 voices across 178 language and regional variants. That includes low-resource and Indic languages served by Vitra's own voice models where no commercial coverage exists. How much audio do I need to clone a voice? + A short, clean sample is enough for an instant clone. Better source audio produces a better replica, and Vitra can also train a fully custom voice model from a larger dataset for demanding cases. What do I need to run lip-sync? + A video with a visible speaker and an audio track. If you do not have the audio yet, generate it in the same session with text to speech or a cloned voice. How is this different from standard lip-sync? + Standard lip-sync aligns one video to one audio track. Personalization generates a different audio track and a different sync for every recipient, from a single base recording. Does transcription identify different speakers? + Yes. Speaker diarization detects each voice and labels its segments, which is what makes multi-speaker recordings usable without manual cleanup. Which subtitle formats can I export? + SRT and VTT as sidecar files, or captions burned directly into the video in any of the built-in animated styles. --- ## Structured data ```json { "@context": "https://schema.org", "@type": "CollectionPage", "name": "Vitra Universe Tools", "description": "Individual AI tools for speech, video, and file translation — each one a playground inside Vitra Universe.", "url": "https://www.vitra.ai/tools", "isPartOf": { "@id": "https://www.vitra.ai/#organization" }, "mainEntity": { "@type": "ItemList", "numberOfItems": 11, "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Text to Speech", "description": "Generate natural AI speech from text in 75+ languages with 12,000+ voices.
