Use of Language
If you’re giving a speech to friends or colleagues, a familiar or informal speech is the way to go! This type of language is usually used in a more casual setting, i.e. teaching a lesson that you want to sound as simple as possible or everyday communication.
There are often filler words, jargin, and some unclear pronounciation as the general message is focused on more than all the parts of the speech. See an example on the left!
Formal speeches are typically the ones we prep for. The language in formal speeches is articulate and, in a good formal speech, the speaker is well spoken.
Clear pronounication as well as a wide vocabulary are always well taken, but make sure not to flood the speech with words you found in a Thesauras. Watch President Obama use an educated vocabulary while keeping the speech easy to understand.
Know Your Audience
The most important indicator of whether to use formal or informal language (or a mix of both) is to know your audience and your message.
How familiar are you with your audience? Are you speaking about a topic that is funny and lighthearted or rather serious?
A great rule of thumb is how you would discuss the topic with one of your audience members is how you ought portray it in your speech.
