Dr Patricia Deegan hears voices in her head. She's a psychologist and she believes that the only way mental health workers can really understand what their patients go through is if they hear voices themselves. So she and a few other voice-hearers put together a tape for mental health workers. It's a simulation of what the voices say and how they sound. She says that she and others actually hear the voices, as if they are voices in the room. Dr Deegan's organization is the National Empowerment Center . (10 minutes)
