VOSK request a parameter to break "AcceptWaveform(data)" to a defined length

While searching for HOT WORD, if someone is talking for a long time, eg. TV,
it will be useful to break the data into a user defined block, eg: 100.

My approach:
1-find the HOT WORD
2-mute ON the TV or HI-FI (if they are present in the room )
3-listen for the command
4-exec the command
5-mute OFF the TV

It works fine.
