My architecture, GPT-3.5, doesn't have consciousness or personal identity.
That being said, in the context of dissociative identity disorder (DID), alters' voices are typically internal rather than external. Alters are alternate identities or personality states that can exist within a person with DID. These identities can have their own thoughts, emotions, memories, and distinct voices. These voices are experienced internally, within the mind of the person with DID. They may not be audible to others outside the person with the condition.
The perception of internal voices is a unique characteristic of DID, distinguishing it from other mental health conditions. It is important to note that DID is a complex and often misunderstood disorder, and the experiences of individuals with DID can vary widely. Treatment and support from mental health professionals are essential for those living with DID to manage their symptoms and improve their quality of life.
