Method and calculation
Estimate speech length from spoken-word pace plus planned pauses.
Inputs and settings
Speech Time Calculator accepts Input text; Spoken words per minute (minimum 1, maximum 1000); Extra pause time (seconds) (minimum 0).
Worked example
Speech Time Calculator example — Input text: "Hello world\nA second line\nHello world"; Spoken words per minute: 130; Extra pause time (seconds): 10. Computed output: { "words": 7, "seconds": 13.23076923076923 }
Output and limitations
A presentation includes pauses for demonstrations, audience reactions and transitions. Add those pauses separately from spoken words to estimate a rehearsal schedule. Delivery speed can be reduced for technical material or a multilingual audience; the entered pace remains a planning assumption.
