Speech Time Calculator
Estimate speech duration from the word count and speaking speed.
How to use Speech Time Calculator
1. Enter Speech Word Count, Speaking Speed WPM. 2. The entered speaking rate is assumed constant. Pauses and delivery changes are excluded; use a rehearsal to estimate actual duration. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
The entered speaking rate is assumed constant. Pauses and delivery changes are excluded; use a rehearsal to estimate actual duration.
How the calculation works
Speaking seconds = whole word count ÷ entered WPM × 60. The entered speaking rate is assumed constant. Pauses and delivery changes are excluded; use a rehearsal to estimate actual duration. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Speech Word Count = 300; Speaking Speed WPM = 150. Result: 2 min.
Practical tip
Check the input labels and assumptions against the speech time task before reusing the number.
