I think its safe to say that I have finally cured my speech impediment. Me personally I had a mixture of **stammering, stuttering, mumbling and rapid speech.** I do sometimes talk very rapid when im nervous and occasionaly mumbling but in due time those impediments will soon start to fade. The above method was definitely one of the leading reasons why my speech improved so rapidly. I have taught myself to speak very slowly and follow a rhythym with my speech which I have turned into a habit by watching and talking over these scenes continously. **The trick is to immitate exactly how the actors are speaking. Copy the emotion, facial expressions and volume of the actors as if youre the one acting the scene out. Only then will you start to see improvements.** I would definitely recommend trying the above method and if you have any questions or anything please let me know :)
