Voice Disabilities

Conditions that partially or completely impair a person's ability to produce speech using their natural voice. Voice disabilities range from mild hoarseness or reduced volume to complete inability to vocalise (aphonia). Causes include laryngeal conditions, neurological disorders such as cerebral palsy, ALS, or stroke, surgical procedures such as laryngectomy, traumatic injury, and developmental conditions. Voice disabilities create significant barriers to telephone and VoIP communication, which are inherently voice-based, and to face-to-face conversation in noisy or group settings. Assistive technologies for voice disabilities include speech generating devices, text-to-speech systems integrated with communication platforms, and augmentative and alternative communication (AAC) tools.
