FAQ
How do I use this speaking time calculator?
Why might playback not work?
Some browsers (especially on iOS) require a user gesture before speech starts. If you still do not see voices, try desktop Chrome, check your device voice settings, and confirm your device is not muted.
Is this speaking time calculator accurate?
It measures playback duration and derives WPM from your word count. Real speaking time can vary with pauses, emphasis, audience interaction, or slides. If you are rehearsing for something important, do a practice run and adjust the Rate slider to match your natural delivery.
Do you upload or store my text?
No. Your text stays in your browser. Playback uses your device's built-in speech engine when available.
Can I change the voice and speed?
Yes. Choose a voice (if your browser provides multiple voices), then adjust rate, pitch, and volume. Total speaking time is based on playback, so rate affects the result.
