The 5.96" Nexus 6 looks like a pretty serious, and very large phone. It's made by Motorola and has very impressive specs. It runs Android 5.0 Lollipop.

The 8.9" Nexus 9 is a new Nexus tablet made by HTC. This one runs Lollipop, too.

The Nexus Player is Google's new Apple TV, Amazon Fire TV and Roku competitor that runs Android TV. Voice search looks just like the Fire TV, and should work great. Google excels at voice recognition technology.
