Longest pause
The longest silence inside your recording, what it usually means when it grows, and why our figure tends to be conservative.
The longest single silence between words in your recording.
Short pauses are normal and good — everyone breathes and thinks. What matters is the long one, because a long pause is almost always the same thing: you stopped to plan.
Under a second is nothing. Two or three seconds is the moment a listener starts to wonder whether you are finished.
Silence at the end counts
If you run out of things to say with fifteen seconds left, that counts as a pause. It has to: it is exactly the failure worth showing you. Measuring only the silences that get closed by more speech would hide the most common one.
Our number is probably an undercount
Worth knowing so you can read it fairly. We calculate pauses from the timestamps of the transcription, and transcription tends to stretch words to fill the gaps around them. The effect is that our figure comes out lower than what a microphone would have measured on the same audio.
Use it to compare your own takes against each other. Do not read it as an absolute measurement of your silence.
