'Voice' in the Bible

You are conscious that when you were Gentiles, in whatever way you were guided, you went after images without voice or power.

Even things without life, having a voice, such as a music-pipe or other instrument, if they do not give out different sounds, who may be certain what is being played?

There are, it may be, a number of different voices in the world, and no voice is without sense.

But if the sense of the voice is not clear to me, I am like a man from a strange country to him who is talking, and he will be the same to me.
