Here is a screenshot of what you will find when you click to the left of the message box in the Messenger App. The screenshot is of an Android version.

Lots of big pictures from us but an even bigger development from Facebook as it gives voice options to its mobile users that they may have gone outside of Facebook to use in the past.
Honestly not sure how much I would use this. What about you?
