VoiceThread is a cloud-based media tool that allows users to collaborate on and communicate around media presentations. These VoiceThread presentations include images, video, and documents, and they provide the opportunity for teams of people to annotate using drawing tools, voice comments, written comments or video responses. They can be used to provide feedback, co-author, narrate, lecture, and even host asynchronous meetings. All of the of the collaboration, interaction and discussion is asynchronous. No scheduling is required, which makes VoiceThreading as efficient as email but as rich as web conferencing and live classroom formats.
