The Valsalva response has to do with your vocal cords. The fluent speaker’s brain tells the vocal cords to open during speech whereas the stuttering brain tells the vocal cords to close during speech resulting in stuttering. I discovered that my brain was wired differently than a fluent brain after years of researching the brain to find an answer. I found the answer and I am hoping to help others to find the answer. I do have to say that fluency has been a life changing experience. I am doing this for free. Depending upon where you live we can connect with WhatsApp or zoom. Let me know if you want to connect.
