FAQ
What people usually ask before they run it
How does subtitle to speech work?
Upload a VTT subtitle file, review the subtitle lines and timestamps, choose an AI voice, then generate audio. Each subtitle cue is turned into speech and assembled into the final track for download.
What does strict mode do?
Strict mode forces the generated speech to fit the subtitle timestamps more closely. It is useful when timing accuracy matters, but the voice can sound slightly less natural in tight subtitle windows.
Can I upload scripts or documents instead of VTT?
Yes. You can upload text-based files such as TXT, MD, PDF, DOC, DOCX, and PPTX. VTT is the best option when you need timestamp-aware subtitle timing.
Should I use subtitle to speech or text to speech?
Use subtitle to speech when you have VTT subtitle timing and want cue-by-cue control. Use text to speech for plain text, articles, and long documents that do not need subtitle timing.
How much does it cost?
4 credits per minute of generated audio.
