Features
What is subtitles to speech?
Subtitles to speech turns a subtitle file (.srt) into a spoken voiceover: instead of reading captions, each line is synthesized into natural AI speech and placed on a timeline that matches the subtitle timings. It's the fastest way to create a narration or dub track from subtitles you already have — upload the file, pick a voice, and download the audio.
How it works
- Upload your .srt subtitle file.
- Pick a voice (or let SaydiVoice choose) and preview a line.
- Press Generate all — we voice every line and stitch the timeline.
- Download the finished voiceover audio.
Frequently asked questions
What subtitle formats can I use?
SaydiVoice reads standard SubRip (.srt) subtitle files. Upload the file and every cue is turned into speech, kept in sync with its start and end times.
Does the audio stay in sync with the subtitles?
Yes. Each line is paced to fit its subtitle slot, so the generated voiceover tracks the original timing. You can also switch to a natural, back-to-back read if you prefer.
Is it free?
Yes. Turning subtitles into speech is 100% free and needs no account. Upload your .srt, generate, and download the audio at no cost.
Which languages are supported?
Many — including English, Vietnamese, Chinese, Japanese, Korean, Spanish, German and more, with a large library of natural voices for each.
Can I fix or re-voice a single line?
Yes. Every line can be reviewed, edited, given its own voice, or regenerated on its own — lines you already voiced are reused, so nothing is wasted.
Can I download the result?
Yes. Download the assembled voiceover as a WAV file to drop into your video editor or player.
