The Amazon Echo is now more capable of handling your schedule, allowing you to add items directly to your Google Calendar. While you could previously ask Alexa about your upcoming events, now you can use your voice to manage your calendar as well, using only your voice. Just say something like "Alexa, add dinner with Kathleen to my calendar for Thursday at 7:30 p.m." and that event will be added.

Alexa has also expanded her skill set, adding content to its Flash Briefing feature. Fans of NBC's The Voice singing contest can now play exclusive behind-the-scenes interviews with current contestants on the show. All you have to do is add "Inside The Voice" to your Flash Briefing in the Alexa app.

In celebration of Earth Day, Amazon has created a playlist called "The Great Outdoors" to Prime Music, which you can of course play through your Echo. You can also ask Alexa what you can do for Earth Day to get some environmentally-friendly activity ideas.
