unvoiced

/ˌˈʌnˌvɔɪst/

Anything that's never spoken out loud is unvoiced. You may go along with your friend's plan to ride an enormous, frightening roller coaster, smiling despite your unvoiced terror.

This adjective can simply mean "silent," or "not said," like at a disappointing city council meeting where the concerns of a large group of citizens remain unvoiced. It can also mean that something is implied and understood, despite never being spoken aloud. Though a reporter's questions sound respectful, her unvoiced criticism might offend the politician she's interviewing. In speech, unvoiced means "with no vocal cord vibration."
