How to Control your speech rate
Your speech should be fluent but neither too hesitant nor too gushy. Say your words slowly enough to be understood and fast enough to sustain the audience’s interest. In speaking, this is ordinarily between 130 and 150 words per minute, and in oral reading between 150 and 175 words per minute. The discussion of light subjects and the presentation of simple narrative material and exciting ideas can be carried on at a faster rate than the presentation of complicated instructional material in unfamiliar subject-matter areas.
When a number of listeners are included in the discussion (other things being equal), the rate should be slower than when there are only one or two persons. Situations involving distraction require a slower rate than situations which are free from distraction.
Rate variation is an effective way of suggesting the nature of the thought being expressed and the relative emphasis to be given to it. The timing of the punch line, for example, is very important.
Practice to determine your most effective rate in speaking and oral reading
Your speaking rate should vary with the relative importance of the ideas, and it should never be so fast that your phrasing or emphasis suffers.
If you dependent on such excess vocalizations as “er” and have a friend listen to your speech and signal. You whenever you use one of these sounds. This will be distracting at first but it will help to break your dependence on this habit.
