Yes!  If you are in Live View and can see your pet, you may speak through the camera to them.  Here are the 4 easy steps:

1. If the Live View tool icons are not showing at the bottom, tap anywhere on the screen to bring them up.
2. Tap on the microphone icon (Talk) on the bottom tool bar.
3. Speak to your pet.
4. De-select the microphone icon so you can listen to your pet’s reply. If the speaker icon (Mute) in the highlighted, denoting it’s muted, tap on it to hear what’s coming through your camera.

Note you will have to select and de-select the microphone for conversations.  The audio will go through only one source at a time (either through the camera or through the app on your phone).  It’s sort of like a walkie-talkie function, but cooler.
