Why can persons who stammer sing without difficulty?
One more of the unusual facts about stammering is that even the person with the severest stammer can sing fluently without any speech blocks. This is because when we sing a song, we know exactly when to say the words and there is no ambiguity in our minds about this timing. In conversational speech however, we cannot bank on any such cues but as normally fluent speakers, most of us do not need these cues. However, without these cues, the speech of a person who stammers becomes disoriented, because of his ‘wrongly tuned’ neurological speech-timing system. He experiences difficulty in maintaining a smooth forward flow of words in feared situations.
