To each their own. My SLP says any gradual fluency will bring more fluency. She gives me the craziest techniques that she evens say I wouldn't do in front of people like rubbing my cheeks or moving my arms in a wave-like motion to relax my shoulders. In fact, I was just saying good morning to people without having to use it after doing it a couple times. Maybe use it in the morning to get the vocal chords warmed up.
