Speech Time Calculator
Paste a script, or enter the word count, and this returns how long it takes to say out loud at the speaking rate you choose. The named bands run from 100 words a minute for slow deliberate delivery, through 120 for a measured presentation and 150 for average conversational English, up to 180 for fast delivery, and there is a box for a rate you have timed yourself. A third action runs it the other way, turning a ten minute slot into a word count and a page count. Reading silently is faster than speaking, so a script always takes longer to deliver than it took to read.
