Sure thing. I talk to all my animals...heck all animals period...all the time. Because they respond to it.
No no...they don't talk back. Yes I have mental disorders but I'm not THAT bad. But they respond in other ways.

Talking to your animals (except maybe fish) calms them, helps them to know you, and calms you as well. Animals can learn from being spoken to as well, and not just cats dogs and horses.
My snakes, of course, can't hear me per say... but they are soothed by the vibration when I talk while holding them.
My BTS on the other hand recognizes when he's being spoken to and looks over at you. He seems to have learned his name, at least, and loves hearing people talk to him.
And every cat I've ever owned has always responded to my talking. Whether they understand is a big debate I won't get into...but they DO know and respond to the voice.

Besides, who doesn't find chatting to their pet a great way to unload after a bad day, or a wonderful way to cheer up when down?
