Arthur Birling is described as a "heavy looking man, rather portentous man in his middle-fifities, with fairly easy manners but rather provincial in his speech". He speaks in a British accent and is mostly calm, but he does get a bit loud and aggressive sometimes, especially in the end. He has a deep voice, and his facial expression is serious most of the time, except when he gets angry. He almost never laughs and many times he has a confused and frustrated look. He speaks a bit fast, and he speaks faster when he gets nervous or angry. He sounds very powerful and speaks with pride.
