With Voices, students use English as a tool for global communication, encouraging them to celebrate the connections between people from diverse cultures and backgrounds. Carefully structured activities with real-world content fully prepare students for interaction and guide them in developing their English voice. Voices is an integrated, seven-level skills program for adults and young adults, empowering instructors to confidently teach in all classrooms. Supported by a logical lesson sequence and The Voices Professional Development Video Collection, we provide teachers with the learning resources they need to deliver engaging courses, both online and in person. Students develop their English voice by: listening to and watching National Geographic Explorers share their real-life experiences for interesting and relatable examples of people contributing to the global English-speaking community; responding to the question "What would I do?" in various cultural and hypothetical situations to practice the mediation skills needed for social interactions in English; and developing fluency using a practical pronunciation program focused on clarity and comprehension.
