Yes, yes they have to.

How does an AAC device work?

Like a regular communication system, the AAC system also had an input and output stream. The only difference is, however, that the input fed in is not a speech signal. The input fed is usually in the form of symbols, hand movements or gestures, eye pointing and blinks, vocalization or facial expressions. Based on user commands, the corresponding output is taken into account.

Some users may require one while others may need a combination of two or more AAC devices to perform the required tasks. These devices can either be voice-activated or keyboard-controlled.
