Pretty cool! Kindle Fire and Kindle Fire HD now have an Immersion Reading program that allows listener / readers to listen to a narrated audiobook from Audible while seeing the highlighted printed text. This is an ideal situation for improving reading.
Whispersync for Voice has also improved the integration for listening-based readers that allows them to switch between where they were in an audiobook, watching a video, etc. 15,000 Kindle and audiobooks are available for Immersive Reading.
