October marked alternative and augmentative communication (AAC) awareness month. AAC includes all means of communication that a person may use besides talking. Low-tech methods include means of interaction like hand gestures, facial movements, or pointing, while more high-tech tools might include a speech generating device accessed through pointing or a joystick, eye-tracking, or even a brain-computer interface.
British physicist Stephen Hawking was long the most famous person associated with AAC, using an advanced computer system to generate sentences and speech. American actor Val Kilmer is another well-known person who has used AAC. Kilmer suffered irreparable damage to his voice due to throat cancer. However, in the latest installment of the Top Gun film franchise, artificial intelligence was used to “clone” the actor’s voice.
