Your Vocal Power – volume, inflection and rate of speaking combined – can significantly impact your audience’s attention, interest in your message … and positive impression of you.
In our culture, we tend to interpret a soft-spoken voice as coming from a speaker lacking in confidence or credibility. Not good reactions for your audience to have about you. Even on a microphone, the soft-spoken voice delivers that weak impression loud and clear. It doesn’t matter if these reactions are valid or not – remember the Perception is Reality demon. If you sound weak to the audience – you are!
