I've not tried any but I do use some of the techniques such as taking deep breaths before uttering the difficult words or using some of our comfort words to make it easier for us to speak or get the next word. Like I had mentioned earlier, the breathing technique is draining me completely and what do I do when the words are just refusing to come out of my mouth even if I try to or want to speak, adding to my frustrations. Anyway, I'll check that program out. Thanks for sharing it with me ❤️
