Big trouble with Stammering, affecting corporate life. Please help Hi Folks, I am having stammering issue when I begin speaking english. I don't find stammering in my mother tongue language. I recently joined new company and my stammering has been increased a lot and embarrassed a lot. I never taken any treatment on this issue, could you please suggest on how can I overcome this problem. Thanks a lot in advance. ​
