Useful now / no app required
Small voice tools with visible limits.
Measure a dictation sample, estimate a script’s speaking time, or format prepared text into a starter subtitle file. The entered text stays in the browser and each result explains what it cannot prove.
Free speaking time calculator
Estimate how long a script, speech, narration, or dictation will take at a pace you control.
- Result
- Estimated delivery time at a chosen pace
- Boundary
- Real pauses, emphasis, interaction, and accessibility needs change timing.
Free transcript to SRT formatter
Turn prepared transcript text into a starter SRT cue sheet locally in your browser, then review timing against the media.
- Result
- A downloadable starter SRT cue sheet
- Boundary
- Approximate cue timing must be checked against the source media.
Free subtitle timing shifter for SRT and VTT
Shift every cue in an SRT or VTT subtitle file earlier or later in your browser to fix out-of-sync subtitles, then download the corrected file.
- Result
- A resynced SRT or VTT file
- Boundary
- Corrects a constant early-or-late offset, not timing that drifts or a wrong frame rate.
Free SRT to VTT and VTT to SRT converter
Convert subtitle files between SRT and WebVTT in your browser while keeping cue timing intact, then download the converted file.
- Result
- The same cues rewritten as SRT or VTT
- Boundary
- Changes the format only; it does not restyle positioned or karaoke captions.
Free subtitle reading speed and line length checker
Check an SRT or VTT file in your browser for cues that read too fast or run past a chosen line length, so captions stay comfortable to read.
- Result
- A list of cues that read too fast or run too long
- Boundary
- Flags readability against your limits; it cannot see the video or judge accuracy.
Privacy boundary
Local input, optional page measurement.
The calculations and file creation run in page JavaScript. The tools do not send entered text to the Voice Typing Aid contact endpoint or a transcription service. They do not use a microphone and cannot measure speech-recognition accuracy by themselves.
If optional analytics is accepted, the site can measure ordinary page and conversion events; it does not include the text-field contents. Choose Necessary only to keep those providers unloaded, or replace a prior choice from the footer.
