Listening to someone talk isn't at all like listening to their words played over on a machine. What you hear when you have a face before you is never what you hear when you have before you a winding tape.
For mankind, speech with a capital S is especially meaningful and committing, more than the content communicated. The outcry of the newborn and the sound of the bells are fraught with mystery more than the baby's woeful face or the venerable tower.
The world does not speak. Only we do. The world can, once we have programmed ourselves with a language, cause us to hold beliefs. But it cannot propose a language for us to speak. Only other human beings can do that.
