Audio is the major void in the space. We can use Aviary's Myna to capture and store audio, and give a link or embed code. But I think you need a desktop computer to use that tool. I wonder if Aviary is planning an App? The Aviary tools are now available as a menu in my Firefox browser and can be embedded into GoogleApps. Of course, if the software is based on Flash, it won't work on an iPad. I have AudioBoo on my iPhone (but haven't used it yet... maybe that is the solution?).
Here is are two common situations with a need for easy audio recording and embedding:
- ESL students need to be able to capture speaking samples, to compare their progress over time. When my daughter was teaching English at a High School in Budapest, we used their mobile phones and MP3 players to capture their speaking samples, but never went the whole way and create an ePortfolio that stored all of those speaking samples. I worked with a university in Mexico that was having students use Audacity to record their speaking samples, uploading them to a free storage site, and used Blogger to organize the links and reflections (it was an awkward process).
- Early readers need to capture their oral reading skills. Here is a 2006 Apple paper (PDF) on Language Acquisition with the iPod. Here is Wes Fryer's 2009 blog entry on Kathy Shirley's project on Transforming Reading and Language Acquisition using iPods.
