There is some kind of disruption between our thought and our speech mechanism. So I recommend experimenting with different speaking modalities, and zooming in on the modality that allows you to express yourself better. For me these 2 things helped to the point that I'm 80-90% confdent in most speaking situations, and I've started to regularly give presentations at work: 1) Speech modality: Thinking back on times where I felt comfortable speaking, I remember speaking to people that are super chill and relaxed. With those people, I didn't feel the pressure to keep up with their vibe, and this would improve my speech significantly. I realized that I stutter when my mind is racing at 100 mph. So I needed to slow down my mind, and establish better mind-body connection. Speaking slowly, taking pauses and relaxed breath would naturally allow me to do this. So I experimented with speaking verrrrrrrry verrrrrrry slowly with strangers (clerks at grocery store, library, called up businesses asking some questions, etc.) The purpose here was NOT to permanently speak slowly, but to train my brain to slow down. Sometime the only way to influence your brain is by manipulating your body. I did this consistently for 2-3 months before I felt my internal thoughts were starting to slow down as well. These days, whenever I start stuttering, I take a pause, and take a deep breath, and tell myself "SLOWWWWW DOWWWWWWWWN" ...... this triggers the muscle memory that I've been practicing. 2) Willingness to voluntarily stutter: This works like magic, but takes some practice. I had heard about the effectiveness of voluntary stutter. So on my doctor's visit, I tried to stutter voluntarily on words that I normally stutter on. Weird thing happened - the more I stuttered voluntarily, the less I feared those words. Once you're open to 'show' your stutter to others, and not fear their judgement, 90% of resistance that we normally build up around those words go away - poof. Again, this required practice for another 3-4 months before I could comfortably start stuttering voluntarily. In high pressure situations like presenting in front of 100 people, I've openly and unabashedly stuttered on my name while introducing myself. Once I do this, I feel a sense of immense relief and freedom, You have to experience it to understand what I'm saying. Once you do, you'll start looking for opportunities to stutter openly. Try it out. And let me know if you'd like to discuss further..... good luck!
