Effective public speaking can be developed by joining a club such Rostrum, Toastmasters International, Association of Speakers Clubs (ASC) or International Training in Communication (ISC) in which members are assigned exercises to improve their speaking skills. Members learn by observation and practice, and hone their skills by listening to constructive suggestions followed by new public speaking exercises. These include:
Oratory
The use of gestures
Control of the voice
Choice of vocabulary
Speaking notes
Using humour
Developing a relationship with the audience
International Federation of Professional Speakers affilates (often called National Speakers Association) offer a similar service for those whose occupation is a professional speaker.
