Does Hypnotherapy works with stammering ?

Does Hypnotherapy works with stammering ? Hello Everyone, I'm 25y/o Male and since the age of 5 i had severe stammering. For the past couple of years i joined speech therapy because of that my speech improved a lot. But now i've reached a point where no matter how much practice or speech methods i use nothing is getting me better. When i talk to someone i stammer but when i do reading its almost fluent. I also have low self-esteem and low confidence issues. So, recently i read about hypnotherapy for stammering and for me it looks promising. Does anyone else tried hypnotherapy for their stammering/stuttering here ?? *Btw english is not my first language*
