AI Transcription and Subtitle Translation

DynTube StreamAI can generate a transcript from spoken audio and translate completed subtitle content into additional languages. You can also upload existing subtitle files when you already have approved captions. Both paths produce tracks that should be reviewed before publication.

Choose automatic generation or upload

Use StreamAI when captions do not exist and you want DynTube to process the audio. Use manual upload when a captioner, translator, or existing workflow has already produced the subtitle file. DynTube accepts supported subtitle uploads, with SRT converted to WebVTT for delivery.

Automatic subtitle workflow

1. Choose the video and its spoken source language.
2. Request transcription and wait for the job to complete.
3. Review names, specialist terms, punctuation, timing, and speaker changes.
4. Request each target-language translation from the reviewed source track.
5. Review translated meaning and timing, then publish and test the player labels.

How usage is measured

StreamAI usage is based on processed audio minutes per language pass. Transcribing a source is one pass; translating that duration into each additional language adds another. Use the current StreamAI pricing page and account balance for the rate and volume that apply to your account.

Quality and accessibility checks

• Correct product names, people, acronyms, and domain-specific vocabulary.
• Check reading speed, line breaks, and synchronization against the audio.
• Verify that each language label matches the delivered text.
• Include meaningful non-speech information where accessibility requirements call for it.
• Test desktop and mobile player controls before sharing the video.
