Confused please help – Dog Communicator - Bark Sounds Translator Review

I'm a little confused, I was reading the reviews and some people said they hit a record button.. where would that be? It only has the options like "Bark" then they have A,B, and C...can someone please help? I love my fur babies and I wanna bond with them so bad ?
