Read your script before you record.

Estimate spoken time, plan paragraph beats and find long sentences using your own delivery pace.

Paste the words you intend to speak and select your delivery pace. The calculator turns word counts into an estimated timeline for each paragraph. It also lists sentences over 30 words, frequent words and simple call-to-action signals. These checks help you plan a read-through; they do not judge the factual quality of your script.

Separate paragraphs with blank lines to create beats. Add [pause=2] for a two-second pause; each explicit pause can be 0–30 seconds. An optional target lets you see how far the estimate is above or below your planned duration. The range shows what happens if your speaking pace changes by 15%, rather than a statistical confidence interval.

How to use

  1. Paste the spoken script; leave out production notes you will not read aloud.
  2. Set words per minute from a short recording of your own voice.
  3. Add blank lines for beats and explicit pause markers where needed.
  4. Review the timeline and read the flagged sentences aloud.
  5. Adjust the script or pace, then run the estimate again.

How to use the result

Uses word count, selected pace and explicit pauses. The pace range is a scenario rather than an audio measurement.

  1. Read one paragraph and compare the timing.
  2. Check pauses against your actual delivery.
  3. Choose Shorts excerpts only after checking context.

Frequently Asked Questions

How accurate is the script duration estimate?

It divides the spoken word count by your selected pace and adds explicit pauses. Delivery, emphasis and unmarked silence change the real duration. Record a short sample to choose a useful pace, then verify the full script aloud.

What counts as a long sentence?

This tool flags sentences over 30 words as a reading aid. That threshold is a review prompt, not a language rule or a YouTube requirement. Keep a longer sentence when it sounds natural and is easy to follow.

Does this analyze my recording or predict retention?

No audio is analyzed. The timeline is an estimate based on the text and pace you choose. Repeated words and call-to-action signals are simple text checks; they do not establish whether viewers will keep watching.
