After using Slidecast I decided to check out VoiceThread.
Originally, I had planned on syncing my audio recording with my Google Docs presentation using Voice Thread, but I soon became frustrated and moved onto Slidecast. After taking a second look at Voice Thread, some of my frustrations have been sorted out, but my conclusions are similar.
Within my experience (but please, try them both out yourself!)…
I find that Slidecast has straightforward audio syncing capabilities. Voice Thread seems simpler, but the audio must be ready to go when you upload. Slidecast made me feel assured that I have some control over the syncing process. Voice Thread allows audio, video, and textual commenting right on its page. So maybe if I’m so squeemish, I ought to just record straight onto Voice Thread.
Slidecast was neat to learn, even if I didn’t record my commentary from its page. I could edit my audio with Audacity (which I’ m now using to record my ukulele song sketches: ) and then sync to my choosing with Slidecast. I would recommend introducing both systems into the classroom.
