Mutism

The inability to speak — from various causes.

---

Mutism refers to the full or partial inability to speak. Causes include neurological damage (brain injury, stroke), apraxia of speech (inability to coordinate the muscles required for speech), trauma, and conditions such as autism spectrum disorder — where communication difficulties can range from unusual speech modulation and repetitive language to a complete absence of spoken language. Unlike selective mutism, many forms of mutism are persistent and not limited to specific social contexts. It is never deliberate rudeness or indifference.

What they cannot do

• Produce speech — at all, or reliably across different contexts
• Use voice-to-text or text-to-speech naturally in all social situations
• Communicate at the same speed or pace as voice users
• Always make their needs or feelings immediately understood

Common misconceptions

• They can speak if they really want to
• They're deliberately ignoring everyone
• They would use voice if they actually wanted to be here
• Mutism is the same as being mute by personal choice

How to actually help

• Accept all forms of AAC (text, symbols, pre-written phrases) as equal to voice
• Never pressure them to speak or imply that text is an inferior substitute
• Allow asynchronous contribution — they may engage differently but genuinely
• Ask about their preferred communication method rather than assuming
