You amplify your voice so that it can be heard loudly and clearly by all listeners within 500 feet, even if other ambient noise would otherwise block the sound, and without becoming jarring or distracting. This doesn't increase the range or area of other auditory or linguistic effects, and physical barriers such as walls and doors still block or muffle your voice as normal. You gain a +1 status bonus to checks to Coerce and to auditory Performance checks to Perform at a large venue. You can Dismiss the spell.
