In the two previous newsletters we have explored the difference between the terms speech and language. This brings us to a discussion of communication. Communication is a complex process for exchanging information between sender and receiver that can be verbal or nonverbal.

Communication requires the process of encoding and decoding. For example, with a spoken message the speaker encodes the message by converting an idea into a stream of sounds. Through articulation, these audible segments are transmitted to the listener. The listener then decodes by converting the signal back into an idea (Owens, 1996).

Verbal communication involves both speech and language. However, speech is only a small component of the message that we send. A significant amount of information is communicated nonverbally through use of facial expressions, gestures, body language and tone of voice.  Additionally, speech is just one mode of communication. We have the ability to communicate with language in writing, reading and with use of manual signs.
