In my experience, clicker training can very well help heighten somebody's motivations to do voice training. The reinforced amount of barks could be considered a downside tho. Also panting can be really beneficial for voice training imo. Just the airflow making sound is really nice to get feedback on larynx raising stuff and for some reason that exercise comes quite natural to some people.

its like a call, i think it might refer to group call situations like discord, but i just use it for any calls
