Siri confusing users

My wife and I both have iPhone 4s running OS 6 and use the same Apple ID to coordinate or calenders, contacts, messages, email. reminders,etc. Siri gets us mixed up name-wise. Is there a way when she asks Siri a question on her iPhone that Siri uses her name and when I ask Siri a question on my iPhone Siri uses my name or, alternatively, no name at all?
