You amplify the voice of a creature you touch, allowing it to reach a vast audience. Every creature in a radius of up to 1 mile around the target hears its spoken words at the same volume it would if the target stood within 10 feet of it, regardless of distance or obstacles between the target and the listener. You or the target can use an action to adjust this radius, or suppress the effects of this spell and allow the target to speak at a normal volume (no action required), and the target can use an action to end this spell.
