Public speaking does not always have to be done in public.
In fact, if you are holding teleseminars or host a show on internet radio, you are a public speaker.
Anytime you are sharing a message or speaking to a group of people about what you know, that is a form included under the activities performed by a speaker.
You may want to teach your audience about something you already are an expert at, giving them the opportunity to learn from you.
It is a good idea to provide some kind of a handout, even if it is only a few pages long.
This is especially true if you will be talking on a topic that has words that may be difficult to spell or has definitions they may not be familiar with.
If you are including URL's to websites or blogs, it is also a good idea to have it written down.
The use of a PowerPoint presentation is always up for debate.
Many event coordinators require you to submit a PowerPoint presentation in advance, just so they can see what you will be sharing with their audience.
Some public speakers even feel more comfortable doing it this way.
If you get nervous or are likely to forget about what you are saying, it is always nice to be able to look up on the screen to find your place.
You will want to refrain from reading each slide to your audience because they could do that without you.
Instead, refer to the slide and then elaborate on each point using your own words.
Teleseminars are much more informal and can be done from your home, but you still will want to provide a study guide or other written material to your listeners.
This will give them something to refer to during your teleseminar, as well as a way to remember your name and website address.
