This is exactly how I was able to reach fluency on a consistent basis and with long term effects. I spent over 20 years researching how the brain learns. I was able to actually rewire my brain to gain voluntary control of my Valsalva response which I strongly believe is the causal factor of stuttering. I have rarely had a relapse for the past 5-6 years. If you would like a demonstration we can connect with WhatsApp.
