About this tool

Planning voiceovers, podcasts, or presentations requires knowing how long text takes to read. Our Text to Speech Calculator estimates audio duration based on word count and speaking speed.

Average speaking speeds: Slow (100-120 WPM), Normal (130-160 WPM), Fast (160-200 WPM). The calculator accounts for natural pauses and punctuation.

Usage examples

Podcast Script

1,000 words at normal speed

1,000 words ÷ 150 WPM = 6 minutes 40 seconds

Presentation

500 words at slower pace

500 words ÷ 110 WPM = 4 minutes 32 seconds

How to use

  1. Paste your text into the input field.
  2. Select the "Speaking Speed" (slow, normal, fast).
  3. Click "Calculate" to get estimated audio duration.
  4. View duration in minutes and seconds.

FAQs

What is the average speaking speed?

Average conversational speech is 130-160 words per minute (WPM). Slower speech (presentations, teaching) is 100-120 WPM. Fast speech (auctioneers, radio ads) is 160-200 WPM.

How accurate is this calculator?

This provides estimates based on word count and standard speaking speeds. Actual duration varies with pauses, emphasis, punctuation, and individual speaking style. Add 10-15% buffer time for natural delivery.

What speed should I use for YouTube videos?

For YouTube explainer videos and tutorials, use 130-150 WPM for clarity. For fast-paced content (gaming, reactions), 160-180 WPM works. Educational content benefits from slower 110-130 WPM pace.

How do I calculate words per minute?

Record yourself reading a passage, count the words, and divide by the time in minutes. For example: 300 words in 2 minutes = 150 WPM. Practice to adjust your pace.

Does punctuation affect speaking duration?

Yes, punctuation adds pauses: commas add 0.2-0.3 seconds, periods add 0.5-1 second, paragraph breaks add 1-2 seconds. Our calculator includes standard pause time in WPM estimates.

What is the ideal podcast episode length?

Most successful podcasts are 20-40 minutes (3,000-6,000 words). Interview podcasts can run 45-90 minutes. Match length to content depth and audience attention span. Consistency matters more than length.
