You never can overcome stuttering fully its caused by the brain and most i read abt has talked abt that theirs improved the stutter is still there Marilyn Monroe stuttered in a interview got told to stop as she dont stutter she learned to have it barely be heard she learned to avoid it stuttering has no cure! If you once were a stutterer you always are a stutterer its a speech disability an speech impediment there is multiple proves of this theres treatments that may make it appear less but stuttering is always there wether you wish it or not its an neurological disability
