A Computer-Assisted Communication Device (CACD) was developed for patients paralysed by botulinum neurotoxin (BoNT) who are unable to speak due to toxin-induced dysphonia or obstruction from an endotracheal tube for assisted ventilation. The system uses pre-programmed menus and synthetic speech to allow for patient-initiated communication. The CACD was designed to meet the needs of patients who possess normal cognition and hearing, but impaired vision, and who are extensively paralysed but still able to press a switch to make menu choices. The CACD will allow patients to interact more effectively with their health care providers which should aid in their recovery.
