identify a variety of vocal strategies, including tone, pace, pitch, and volume, and use them appropriately and with sensitivity to audience needs and cultural differences (e.g., enunciate clearly, while varying tone, pace, and volume, to ensure that all members of a diverse audience will understand the message; adjust volume, pace, and pitch to suit the purpose of speaking and the size and type of audience; adapt voice to role-play the subject of a biography for a mock interview)
