VoiceThread is an interactive collaboration and sharing tool that enables users to add images, documents, and videos, and to which other users can add voice, text, audio files, or video comments. Typically, an instructor creates the initial narrative slides and students then add their comments at any point in the narration. VoiceThreads can be posted on your website or saved to an mp3 or DVD. VoiceThread can be used to simulate conversations and interviews, allow users to critique and comment on interviews, and analyze a conversation for body language and other nuances such as tone of voice. In short, VoiceThread allows instructional collaboration centered on communication.
