The impact of your voice

Reference: Abintegro                

            Most articles about improving the way presentations are delivered focus on body language and content. Body language accounts for an amazing 55% of the impact you have when talking or presenting to people; what you say or show, only 7%. The remaining 38% of your impact comes from the way you speak.
The three things you should consider when thinking about the way you speak are: • Volume • Speed • Pitch and tone
You need to make sure you’re speaking loudly enough for the people at the back to hear. A microphone may do this job for you, but if you don’t have one simply ask: “can everyone at the back hear me?” That way only the people at the back respond (or not), you get the volume right at the beginning and you won’t get distracted or interrupted once your presentation is flowing.
It’s a great ice-breaker too that will help you to relax and give you a chance to hear your own voice before you really get going.
When you want to add emphasis to a given point it’s a good idea to increase your volume slightly.
Never speak too quickly. It shows you are nervous; it will mean you are more likely to make mistakes and it is less likely the audience will understand what you are saying.
It’s always faster to other people’s ears than it is in your head – so think ‘slow’. Pause after you’ve made an important or complicated point to give your audience time to digest what you’ve said.
Avoid a monotone voice at all costs. Reading from a script increases your chances of presenting in a monotone. So try to do your presentation from notes, rather than a script. If you have to read it, practice varying your pitch in an exaggerated way as if you’re reading a scary or exciting child’s story. Don’t deliver your presentation like that, however, just get used to hearing that range in your voice.
Using either genuine or rhetorical questions will help keep the flow of your speech varied, which will keep the audience engaged.
Enunciate clearly and don’t mumble into your notes.
