The robotic speak and the likes are mainly during the course itself. The techniques I found most useful for me was hit & hold and assertive first sound (until I lost focus and felt like I was starting a fight with everyone I spoke to) and more so eye contact. I’m not gunna lie and say it will work for everyone but from my own experience, I will fully endorse it as an option to try because we’re all going through the same crap, every day with no end in sight unless like you say, brain surgery can magically make it go away
