Visual aids

Voice quality

It is, of course, important that your audience be able to hear you clearly throughout your presentation. Remember that if you turn away from your audience, for example towards the whiteboard, you need to speak a little more loudly. In general, you should try to vary your voice. Your voice will then be more interesting for your audience. You can vary your voice in at least three ways:

• speed: you can speak at normal speed, you can speak faster, you can speak more slowly - and you can stop completely! You can pause. This is a very good technique for gaining your audience's attention.
• intonation: you can change the pitch of your voice. You can speak in a high tone. You can speak in a low tone.
• volume: you can speak at normal volume, you can speak loudly and you can speak quietly. Lowering your voice and speaking quietly can again attract your audience's interest.

The important point is not to speak in the same, flat, monotonous voice throughout your presentation - this is the voice that hypnotists use to put their patients' into trance!

Of all the information that enters our brains, the vast majority of it enters through the eyes. 80% of what your audience learn during your presentation is learned visually (what they see) and only 20% is learned aurally (what they hear). The significance of this is obvious:

• visual aids are an extremely effective means of communication;
• non-native English speakers need not worry so much about spoken English - they can rely more heavily on visual aids.

It is well worth spending time in the creation of good visual aids. But it is equally important not to overload your audience's brains. Keep the information on each visual aid to a minimum, and give your audience time to look at and absorb this information. Remember, your audience has never seen these visual aids before. They need time to study and to understand them. Without understanding there is no communication.

Apart from photographs and drawings, some of the most useful visual aids are charts and graphs, like the 3-dimensional ones shown here:

Piecharts are circular in shape (like a pie).

Barcharts can be vertical (as here) or horizontal.

Graphs can rise and fall.
