Android Wear expands gestures and voice commands, adds speaker support

Android Wear , Google's wearable device platform, is getting endowed with a number of new input and output features as part of a firmware upgrade set to roll out "in the next few weeks."
On the input side of things, the biggest news is the expansion of gesture controls beyond the basic wrist flick.
With the expanded voice command capability, owners will be able to dictate messages to a variety of apps, including some of the most popular messaging services: Hangouts, WhatsApp, and Telegram.
And with the newly enabled speaker support, Android Wear watches can finally be used as Bluetooth speakerphones for tethered handsets.
