A person who cannot speak or hear?

A person who cannot speak or hear is referred to as deaf-mute or deaf and mute. However, it's important to note that these terms are considered outdated and potentially offensive by many individuals in the Deaf community.

Here's why:

* "Mute" is an outdated and inaccurate term. It implies that someone is incapable of making any sound, which is not always the case. Deaf people can make sounds, and many use their voices to communicate, sing, or express themselves.

* "Deaf-mute" combines two separate conditions and suggests they are always linked, which is not accurate. Someone can be deaf without being mute, and vice versa.

More respectful and accurate terms include:

* Deaf and mute (when appropriate)

* Deaf (if the person has no hearing)

* Hard of hearing (if the person has some hearing loss)

* Deafblind (if the person has both hearing and vision loss)

* D/deaf (used by some Deaf people to distinguish themselves from the medicalized "deaf" term)

It's always best to ask an individual how they prefer to be addressed. This shows respect and understanding of their identity and experiences.
