With VoiceThread, people can have asynchronous group conversations around images, documents, videos and presentations they upload to the site. Once a user shares a VoiceThread, others can comment on it verbally (with a microphone or telephone), with text, by uploading an audio file or by recording a video with their webcam. Additionally, others can review the comments and see who made them.


  • People can virtually collaborate and converse about the media uploaded to VoiceThread.
  • Comments can be added several ways: voice (with a microphone or telephone); text; audio file; and video (via a webcam).
  • VoiceThreads can be shared with others so they can record comments.
  • Users can doodle while commenting, use multiple identities and pick which comments are shown through moderation.
  • VoiceThreads can be embedded to show and receive comments on other websites such as Canvas and exported to play as archival mp4s.
