Google Play Books received a nice update overnight that included a Read Aloud feature, as well as pinch-to-zoom and double-tap-to-zoom gestures. The Read Aloud feature sounds really robotic — even more than Siri or other voice command prompts — but it gets the job done.
It's nowhere near as polished as something like Amazon's integration with Audible audiobooks, but it's also totally free. The zoom functions seemed a liiiiittle choppy when we tried it out on a Nexus 4, but nothing too concerning. And they're both better than the Kindle app's features. You can update the app now from the Google Play. [Google via TalkAndroid]
