The purpose of the A1 speech is simply to allow you to make a start on your speaking journey. This speech will help you to overcome the initial nerves of public speaking and get you used to delivering a prepared speech to an audience. To be successful at public speaking you need to do more than just read books on the subject, you actually need to practice it and this speech allows you to start that.
The best subject for this speech is yourself, or something you know well. It allows other members of the club to get to know you and also what your work is, your hobbies are or find out a bit about your family life.
As part of the development process, the speech will be evaluated by another member of the club using these headings as a framework.
