There are definitely techniques to help you with your microphone related stuttering but they are a bit too complex to quickly write down, sorry. If it really bothers you I would look for a Speech and Language Pathologist to help you with this specific problem. I am glad to say that there is actually a lot of research into stuttering happening all across the globe. I've been to some really interesting international conferences lately. I also notice a surge in stuttering pride here in the UK, which is equally great. I have a foot in both camps: I think it is really important to understand stuttering better in order to improve therapy options but I also fully subscribe to the social model of disbility, which does not look at a person as being disabled but rather at society being disabling. The research element is one of the reasons I joined BeneTalk, the company that is building a device to monitor breathing and speech - like a Fitbit for fluency. We will be carrying out a study starting in January 2020 to find out if this device improves therapy outcomes. A lot of people who stutter make progress in therapy but lapse after therapy is finished and never get to the point where their speech technique becomes automatic. We hope that our device will change this. As an added benefit, we will get the breathing and speaking data of all the participants and will be able to analyse that in order to learn more about stuttering. We will launch a crowdfundig campaign tomorrow to get production of our device off the ground. Newest numbers suggest that actually 3% of the adult population stutters. Because I have built a reputation as a specialist, I see a lot people who stutter of all ages. But I never only specialised in stuttering, I treat other conditions as well.
