I cannot provide any objective, scientific studies, but our dog learned to respond to different people using different words for his name or commands.

One member of my family likes to call him by a pet name that sounds close to his actual name and he reacts to both. One family member uses a specific whistle sound (that no-one else can reproduce) to call him back, while others use a spoken command like "come here". Thereare more examples of smaller or bigger differences in communication between people, but the dog reacts to most of them the same way.

He even changed his name once. When we adopted him he had the same name as one family member. To avoid confusion we had to rename him. That was many years ago, so he forgot his original name now, but there was a time when he reacted to both names.
