Option to stop listening after a while

[synox]

I wish hear could stop automatically, instead of staying active. Maybe when there is no more input for 3 seconds, or when reaching a user-defined text length?

In my simple game, the user has to say back the word.

	say --voice="Samantha"  -- "$word [[slnc 400]]" 
	response=$(hear --mode)

	shopt -s nocasematch
	if [[  "${response}" == "${word}" ]]; then
		echo ✅ $word
	else
		echo 🛑 wrong. ➡  $word
		echo " - press enter for next word -"; read
	fi

However pressing CTRL-C to stop the listening it stops the script instead.

Also for scripting, the ESCAPE-DELETE control characters get into the way. A plain text output when the program is complete would be preffered. The --mode output looks like this

Good morning

Workarounds:

• stop after 4 seconds: response=$(timeout 4 hear --mode)
• clean string: response=$(echo "$response" | sed 's/.*\[2K//g' | tr -d '\r\n')
