Firstly, I am so happy to see your excitement and the fact that you chose to share it in the group to help others is truly heartwarming. This technique is indeed helpful and recommended by most speech therapists. Another popular technique similar to this is breaking down words into syllables which is similar to what you described. It’ll also be useful to not hold your breath when speaking. It happens a lot to me. I try to say everything in a single breath unconsciously and breathing really helps.
