The document discusses two voice recording tools: Vocaroo and Voki. Vocaroo allows users to easily record voice clips with a microphone and share them by sending a link or embedding the audio. The document provides suggestions for how teachers can have students use Vocaroo to record presentations and introduce themselves. Voki allows users to create avatars and add recorded voice, making it suitable for digital storytelling. Teachers are advised to have students record stories, explanations, and presentations using Voki avatars and share them on a class wiki.
