How the Speaking Time Calculator works
The Speaking Time Calculator takes Script or speech text, Speaking speed (words per minute) and returns the answer instantly — no button to hunt for, no page reload. Rehearsed speakers speed up and skip lines, so add a 10% buffer for pauses and slide transitions. A 7-minute talk is roughly 900 words — the number to write to, not "about ten slides".
