Reading, Speaking and Audiobook Time

Estimate how long words take to read, say or listen to. Check a reading time for a manuscript or post, time your own reading speed, convert words to speech minutes, or see how much faster an audiobook finishes at 1.5x or 2x. Reading and speaking speeds come from a published study and named narration guidance, not guesses.
