mutism

[mu´tizm]

inability or refusal to speak, most often because deafness has prevented the person from hearing the spoken word. speech is learned by imitating the speech of others. The child who is born with normal hearing and then loses it may lose part or all of the power of speech through loss of contact with the speech of others.

In other cases loss of speech may be psychogenic in nature. Called also aphonia.
