Compare Devanagari and Roman captions on the same synthetic Hindi source, with downloadable output, phrase timings and clear limitations.
Inspect the result
- We wrote the source script and synthesized each sentence locally with eSpeak NG.
- We measured sentence durations and supplied phrase-timed captions to the local renderer.
- TheMomentra rendered the original landscape frame and captions into a vertical MP4. The saved file is the one you can play and download.

What this example does not prove
- Synthetic voice and scripted source: this is a rendering example, not a customer recording.
- Phrase timings and Roman spellings were supplied for the example; automatic transcription, word alignment and speaker tracking were not evaluated.
- Real speech, accents, noise and names need review. This example does not establish an accuracy rate.
Script and caption timings
This is the script used to synthesize the source, with the supplied phrase timings. It was not recovered by an automatic speech recognizer.
