Hence the need for feedback. Preparation is key. Good morning, I have a tendency of speaking too fast. My instructor thinks the reason why I speak so fast is because I think fast. I do not want this to be a disadvantage for me when I am communicating, particularly on job interviews.
People speak rapidly for a variety of reasons.
Whatever the reason, speaking too fast is a negative and something to try to overcome. The speaker appears to be nervous whether the case or not. You will have to initially speak at a pace that feels overly slow to you. The pace you now speak at seems right to you, so you are not a good judge. Overdo it on the slow side.
