Such observers commonly include a mute person’s family members, caregivers, teachers, and health professionals like doctors or speech and language pathologists. Muteness may not be a permanent condition, depending upon etiology (cause).

Can a mute person scream? Yes, they can. It usually doesn’t sound the same as when someone with full hearing screams, but they can and do.

However, they do get those good belly chuckles that everyone gets when something is funny and they will make the same movements and facial expressions of anyone else laughing, just no sound or vocalization if they are completely mute.

The technology includes giving people the ability to talk again as long as they are able to imagine mouthing the words. Signals from the brain are fed into a neural network computer linked to a voice synthesiser, similar to that used by the late Stephen Hawking – but far quicker.

Physiological mutes can still usually whisper because it takes place almost entirely in the mouth. So the easy answer is that a mute baby is almost always going to have some sort of birth defect causing it and they will not make the high pitched cries when crying, though they will still cry (not silently, but quietly).

Very often, these children show signs of anxiety, such as difficulty separating from parents, moodiness, clinging behavior, inflexibility, sleep problems, frequent tantrums and crying, and extreme shyness starting in infancy.

5 Speech Development Warning Signs

• Your newborn doesn’t startle at sounds.
• Your baby doesn’t follow you with her eyes when you speak.
• Your baby is not babbling by 7 months.
• Your baby hasn’t said any words by 19 months.
• Your child is not using two words together by age 2 1/2.

A person can be born mute, or become mute later in life due to injury or disease.

It depends on the reason for their mutism, and the structures of the neck. In most cases, yes, people who do not speak but who have a structurally complete and functional neck/ larynx do make noise when they cough, sneeze, laugh, etc.
