Re-voicing an existing training video in another Indian language

An induction session or an equipment walkthrough recorded once is transcribed, translated and re-voiced with synthetic speech timed against the original, so a single recording serves sites that do not share a working language. Somebody who speaks the target language signs the cut off before it is published.

Tools named for this

  • Speech recognition covering the languages scheduled in the Constitution of India
  • An open translation model that spans the same set of languages
  • A speech synthesiser with a neutral voice that is not built to imitate the original presenter
  • A named reviewer for each target language, with authority to block publication

What to check before you ship it in India

  • The IT Rules as amended in February 2026 keep outside 'synthetically generated information' any use of a computer resource solely for improving accessibility, clarity, quality, translation, description, searchability or discoverability, without generating, altering or manipulating any material part of the underlying material. A straight translated voice-over can sit inside that proviso. Re-timing the speaker's lips to the new audio, or generating a voice meant to be taken for the original presenter's, alters a material part and puts the output back inside the definition.
  • A presenter's face and voice are their personal data. Where the presenter is a current employee the likely basis is the section 7(i) legitimate use for employment purposes rather than consent; either way the processing stays bound to the specified purpose, so a recording made for one induction video is not a licence to synthesise that person saying something they never said — least of all once they have left the organisation.
  • Nobody downstream can be assumed able to tell. The research community that works on separating genuine speech from synthetic speech runs its evaluations without matched training data precisely because, in its organisers' own framing, the nature of such speech can never be anticipated with confidence.
