Frequently Asked Questions
Is dubbing a one-step process?
No. Start the job with `dub_audio`, then fetch the finished result with `get_dubbed_audio`.
Can it handle multiple speakers and timing?
Yes. It is built to preserve timing and speaker separation in the dubbed output.
Should I set the source language?
Yes, if you know it. Setting `source_lang` improves accuracy, especially for mixed or accented audio.
Can I dub only part of a file?
Yes. Use `start_time` and `end_time` when you only need a segment translated.
