That is correct, but I noticed all the "tricks/hammer tools/helpfull methods" are almost eveywhere the same. In Belgium we have also a method named BLS ( bewust leren spreken=mindfull speaking). I followed this course and it is also about intonation, stretching word, listen to yourself when speaking, try to speak in short sentence etc. I read a lot of books, articles, followed several speech therapy. And at the end it is all about yourself and how hard you want to work.
