kinda, the def of talking changes from discipline to discipline so the law requires i say no, but I have heard this called talking to a duck, speaking out loud, I assume as an homage to nikola tesla and his fascination with pigeons, but i digress; I believe this habit is helpful. The part of the brain that connects your right and left lobe, i assume, is less than 15% of your brain's mass, so getting more brain power on a problem increases the chances of cross talk between wires/nerons. My understanding of the brain is a sparking poorly insulated conductor that just has enough insulation for some of your electrical pulses, like your heartbeat, to not regularly short circuit.
