I don't do the exercises but I subconsciously use the techniques all the time,almost automatically. I still fully use the techniques in situations like where I have to say my name in public or, the worst thing, someone asks me to repeat what I said! these last couple of years have seen me make numerous telephone calls to. insurance and doctors where I am always having to give out information... stuff I cannot change like my name, dob and policy number. the techniques have helped me there. actually, sometimes I do perform exercises before I make some phone calls! like taking some time to breath and get my chest moving. it still helps. you may feel that you come off the course with a strange new voice, and might not like it. I remember thinking on day 1 that I don't want to speak like a robot. but after a few months you will become more natural at incorporating the techniques into everyday speech.
