Verify Subs — fix before you pay
Click "Verify Subs" to scan your file. The system flags overlapping timestamps, missing cues, encoding issues, and overly long lines. Fix problems before converting — saves characters and avoids re-work.
Convert & download as MP3, WAV, or OGG
Hit "Convert Subtitles to Speech" — the AI matches each line to its SRT timestamp. Choose from 5,000+ voices in 146 languages. Download or use the API for batch processing. First 1,000 characters free, no sign-up.
How SRT Becomes Audio
Each subtitle line maps to a voice segment. Timestamps stay intact — the AI speaks exactly when your subtitles say to.
How Subtitle Dubbing Works with Neural Networks
Upload a subtitle file in SRT, SUB, or VTT format. Select the language, voice, speed, and pitch. Click "Convert Subtitles to Speech" — the neural network converts your SRT to speech, voicing each segment according to its timestamp.
Each subtitle's timing (e.g. 00:00:00,000 --> 00:00:02,500) defines when text is voiced. If text is too long, speech accelerates up to 3×. Beyond that — the validator warns you. Common with translated subs or longer languages.
SRT requires a comma before milliseconds — 00:00:02,500 not 02500. Google Translate can strip it — check after translation. Line breaks within a timing block = one sentence. Add periods where sentences end. For plain text, use the standard TTS page.
#
Place # at the start of a subtitle line — SpeechGen voices text at any speed to fit the timing, ignoring the 3× limit. Distribute acceleration across intervals for best quality.
[ ]
Wrap text in square brackets [ like this ] — SpeechGen skips it but preserves timing. Useful for omitting dialogue lines without losing pace in the output audio.
SRT format precision
A misplaced comma or missing line break will break timing. Timecode anatomy:
- Each cue starts with a sequence number (1, 2, 3…) — must increment without gaps
- Milliseconds use a comma, not a dot —
00:00:03,500not00:00:03.500 - The arrow is exactly
-->with one space on each side - End every subtitle line with punctuation (period, ?, !) — without it, the voice drops mid-phrase
- A blank line separates cues — missing it merges two cues into one
