Soft-spoken, hushed, gentle, muted, low, and tranquil are among the antonyms for the term "loud-voiced." Instead of shouting or talking loudly, these adjectives describe a more gentle or soothing voice. If a person is soft-spoken, they seldom need to raise their voice to be heard, while someone with a hushed voice speaks in a whisper that is barely audible. A gentle voice is quiet and soothing, with a calming effect. The terms muted, low, and tranquil describe a voice that is neither loud nor soft, but instead, restrained and calming to those who listen to it.
