Rate
Rate of speaking refers to how fast or slow you speak. If you speak too fast, your audience will not be able to absorb the information you present. If you speak too slowly, the audience may lose interest. The key is to vary your rate of speaking in a middle range, staying away from either extreme, in order to keep your audience engaged. In general, a higher rate of speaking signals that a speaker is enthusiastic about his or her topic. Speaking slowly may lead the audience to infer that the speaker is uninterested, uninformed, or unprepared to present his or her own topic. These negative assumptions, whether they are true or not, are likely to hurt the credibility of the speaker. Having evaluated thousands of speeches, I can say that, in terms of rate, the issue speakers face is speaking too fast. The goal is to speak at a rate that will interest the audience and will effectively convey your information. Speaking at a slow rate throughout a speech would likely bore an audience, but that is not a common occurrence.
Some people naturally speak faster than others, which is fine, but we can all alter our rate of speaking with practice. If you find that you are a naturally fast speaker, make sure that you do not “speed talk” through your speech when practicing it. Even if you try to hold back when actually delivering your speech, you may fall back into your practice routine and speak too fast. You can also include reminders to “slow down” on your speaking outline.
