Communication Rate
Also known as: Communication Speed
The speed at which a person can convey messages, typically measured in words per minute (WPM). For AAC users, communication rate is often significantly slower than natural speech (100-200 WPM)—unaided AAC users may achieve only 2-10 WPM with scanning systems, while more advanced systems with prediction can reach 15-25 WPM. Improving communication rate is a primary goal of AAC research, as slow rates create conversational asymmetry, listener impatience, and reduced opportunities for social participation.
