Vaani

Vaani is a tool for creators, brands, and studios that automatically dubs video content into multiple languages. You upload a video, and Vaani translates the spoken words, generates a new voice track, and synchronizes it with the speaker's lip movements. The core promise is that the translation keeps the original speaker's unique cadence, warmth, and timing, so the result feels like the real person speaking another language, not a generic synthetic voice.

It works through a proprietary four-stage pipeline. First, it isolates the speaker's voice from background music. Then, it transcribes the speech with precise word-level timestamps. Next, an in-house 'transcreation' engine translates the script while aiming to preserve emotional tone. Finally, it mixes the new audio to broadcast standards, normalizing loudness and ensuring the lip-sync is accurate. The tool offers two interfaces: 'Studio' for detailed, timeline-based editing of single videos, and 'Glot' for batch-processing many videos into multiple languages in parallel.

This tool is a clear fit for video creators, educators, and businesses looking to expand their audience globally without the cost and time of traditional dubbing studios. A YouTuber could dub a popular tutorial into Hindi and Spanish. A company could localize training videos for international teams. It turns a video meant for one language into an asset ready for a worldwide audience.
