I have gone to Hollins! Back in 2021!. I personally do not use the techniques. I find them hard to maintain and they make me sound robotic. like with Stretched Syllable, I feel like I saw very animated, and with amplitude contour I feel like I don't sound like I have a normal tone. I found it difficult for me to remain calm and take a full breath every time I spoke to one. I believe that is because the other person expects a rapid answer rather than a full 3-5 sec pause for a breath. Since you use the techniques, do you struggle with feeling like you don't sound like yourself?
