Public Speaking Study Guide #1
1. Communication Model and all its components- encoding, decoding
The source, or sender, is the person who creates a message. The speaker transforms ideas and thoughts into
messages and sends them to a receiver, or an audience.
The speaker decides what messages are to be sent and
how they will be sent.
Organizing the message, choosing words and sentence structure, and verbalizing the
message is called encoding

problem of organization, more flexible, allows for better eye contact, and you can make spur of the moment
Cons: can easily get off track, may become repetitive and wordy.
The full text is prepared, strict time limit, creates speech in a written style. Cons: eye contact is minamalized, no
flexibility. Good use if a speaker wants to avoid being misquoted or misconstrued, or when he is comm exact
descriptions and directions.
Formal situations, written style, inflexible format, long prep time, difficult to have natural delivery.
3. Thesis and why it’s important/ performs a specific speech purpose
: The theme, or central idea, of a speech that serves to connect all the parts of the speech in a
The main points, the supporting material, and the conclusion all relate to the thesis. The point of
creating a thesis statement is to help you identify precisely what the speech is about.
