The next options allow more control. From the VoiceThread site: <https://voicethread.com/howto/setting-up-create-assignment/>
**Allow students to add slides to any VoiceThreads for this assignment:** Allow students to add slides to any VoiceThreads submitted by their classmates to this assignment. (This should generally be disabled unless students are creating a Group VoiceThread or collaborative project, for example)
**Enable threaded commenting:** Turns on the ability for your participants to start threaded conversations.
E**nable comment moderation:** Allows you and the student to preview all comments on this VoiceThread before revealing them to others. You can also choose never to reveal them. Learn more about Comment Moderation.
**Don’t allow commenters to delete their own comments:** Anyone who records a comment on a VoiceThread will be unable to delete it once it is saved. This is a powerful tool for assessment because your commenters will not be able to “retry” after they’ve recorded.
**Limit length of each comment:** By default, all audio and video comments recorded in VoiceThread can be 60 minutes long. If you’d like to set shorter time limits for your commenters, enter your desired maximum comment length here.
**When recording, automatically advance to the next slide after:** Set slides to advance automatically at pre-set intervals as users are recording. In addition, you can check the box for Pecha Kucha or Ignite beneath this option to automatically set the correct restrictions for those presentation types. Learn more about timed presentations here.
**Start playing when opened:** The comments on your VoiceThread will begin playing automatically when people first open it.
**When final comment on a slide has played, automatically advance to the next slide after \_\_ seconds:** When the VoiceThread is in play mode, it will play through all of the comments on a slide and then move to the next slide automatically. The number of seconds is the “pause” time before the slide advances.
**Allow download:** Allow students to download the central media from the VoiceThreads their classmates create.
**Allow export:** Allow students to export one another’s VoiceThreads.
**Allow students to make a copy:** Allow students to make a copy of one another’s VoiceThreads.
