The character changes the sounds that creatures or objects make. The character can create sounds where none exist, deaden sounds, or transform sounds into other sounds. All affected creatures or objects must be transmuted in the same way. Once the transmutation is made, the character cannot change it.
The character can change the qualities of sounds but cannot create words with which the character is unfamiliar.
A spellcaster whose voice is changed dramatically is unable to cast spells with verbal components.
