### Parse interval
Without ``--allow-padding``, whispering just performs VAD for the period,
and when it is predicted as "silence", it will not be passed to whisper.
If you want to change the VAD interval, change ``-n``.
By default, whispering performs VAD for every 3.75 second.
This interval is determined by the value of ``-n`` and its default is ``20``.
When an interval is predicted as "silence", it will not be passed to whisper.
If you want to disable VAD, please use ``--no-vad`` option.
If you want quick response, set small ``-n`` and add ``--allow-padding``.
However, this may sacrifice the accuracy.
By default, Whisper does not perform analysis until the total length of the segments determined by VAD to have speech exceeds 30 seconds.
This is because Whisper is trained to make predictions for 30-second intervals.
Nevertheless, if you want to force Whisper to perform analysis even if a segment is less than 30 seconds, please use ``--allow-padding`` option like this.
```bash
whispering --language en --model tiny -n 20 --allow-padding
```
This forces Whisper to analyze every 3.75 seconds speech segment.
Using ``--allow-padding`` may sacrifice the accuracy, while you can get quick response.
The smaller value of ``-n`` with ``--allow-padding`` is, the worse the accuracy becomes.
