'Voice' in the Bible

For the dream comes through much effort, and the voice of the fool through many words.

Do not allow your speech to cause you to sin, and do not say before the messenger (priest) of God that it was a mistake. Why should God be angry because of your voice (words) and destroy the work of your hands?

Moreover, do not curse the king, even in your bedroom, and in your sleeping rooms do not curse the rich, for a bird of the air will carry the sound and a winged creature will make the matter known.

when the doors (lips) are shut in the streets and the sound of the grinding [of the teeth] is low, and one rises at the sound of a bird and the crowing of a rooster, and all the daughters of music (voice, ears) sing softly.
