You’re walking down the street or sitting in a quiet library when you hear it. A low mumble. A rhythmic, intense conversation held with an invisible partner. When a schizophrenic is talking to someone you can't see, your first instinct might be fear or perhaps a profound sense of confusion. It looks erratic. It feels "other." But for the person living through that moment, it isn't random. It’s a physiological response to a brain that is misfiring signals, turning internal thoughts into external realities.
It’s loud in there.
Honestly, the way pop culture depicts this is a mess. Movies love the "madman" trope, but the clinical reality of auditory verbal hallucinations (AVHs) is far more complex and, frankly, exhausting. When someone with schizophrenia is talking to themselves, they aren't necessarily "lost." They are often just responding to a sensory experience that is as real to them as the sound of your own voice is to you.
The Science of Why a Schizophrenic Is Talking Out Loud
Why does this happen? We used to think it was just "imagination gone wrong." We were way off. Modern neuroimaging, specifically fMRI scans, has shown us something wild. When a person with schizophrenia experiences an auditory hallucination, the Broca’s area of the brain—the part responsible for speech production—lights up.
It’s active.
But here is the kicker: the brain’s "monitoring" system, which usually tells us "Hey, I’m the one who just thought that," is essentially offline. This is what researchers call a failure of self-monitoring or "inner speech" attribution. Essentially, the brain creates a thought, but it forgets to tag that thought as "Internal." Because the tag is missing, the brain processes the thought as an external sound coming from the outside world.
Imagine if every time you had a song stuck in your head, it sounded like it was blasting from a speaker in the corner of the room. You’d probably start talking back to it eventually, too.
Dr. Chris Frith, a pioneer in this research, argued decades ago that this is a breakdown in "forward modeling." Usually, when you move your arm or speak a word, your brain sends a "cancel" signal to your sensory cortex so you aren't surprised by your own actions. In schizophrenia, that signal doesn't work. The person's own "inner voice" catches them by surprise. It sounds like a stranger.

It Isn't Always Words
Sometimes, the "talking" isn't even a conversation. It can be a running commentary. Imagine a voice narrating your every move: He is picking up the coffee. He is sitting down. He looks tired. This is known as third-person narration, and it’s one of the hallmark diagnostic criteria in the DSM-5.
Other times, it’s "command hallucinations." These are the dangerous ones, though they are less common than the media suggests. This is when the voice tells the person to do something. But mostly? Mostly, it's just noise. It’s a crowded room where you can’t find the exit.
The Physicality of the Conversation
When you see a schizophrenic is talking to themselves, you might notice their lips moving without sound. This is called "subvocal speech."
Interestingly, researchers have found that the muscles in the throat and tongue often twitch in sync with the hallucinations. The body is literally trying to speak the words the brain is hearing. It’s a closed loop. The brain hears a voice, the body prepares to respond, and the cycle continues until the episode passes or medication kicks in.
It's not just "in their head." It's in their muscles. It's in their nerves.
The Role of Stress
You’ve probably noticed that these "conversations" get more intense in high-pressure environments. Stress is like gasoline for schizophrenia. When the nervous system is flooded with cortisol, the brain’s ability to filter out "background noise" disintegrates.
- Crowded subways.
- Loud family arguments.
- The pressure of a job interview.
In these moments, the voices get louder, more insistent, and the person is more likely to talk back to them as a defense mechanism or a way to seek clarity.

Breaking the Stigma of the "Internal Monologue"
We all talk to ourselves. You do it. I do it. You probably did it this morning when you couldn't find your keys. "Where did I put those?" you might have muttered.
The difference is the source attribution. You know it’s you. When a schizophrenic is talking, they are often trying to negotiate with a perceived external entity. They might be arguing, pleading, or simply answering a question.
Why do they look angry?
Often, the voices aren't nice. Research suggests that the "tone" of hallucinations is frequently influenced by culture. A famous study by Stanford anthropologist Tanya Luhrmann found that people with schizophrenia in the U.S. tended to hear voices that were violent or hateful. In contrast, patients in India and Ghana often reported voices that were playful or even helpful, like a family member offering advice.
This suggests that the "talking" we see is a reflection of the person's social environment. If society treats you like a threat, your voices might start sounding like threats.
How to React When Someone Is Talking to Themselves
If you encounter someone in public who is clearly deep in a hallucinatory conversation, the best thing you can do is... nothing. Unless they are in immediate physical danger or posing a threat to others (which is statistically rare), they are just navigating a very difficult sensory moment.
- Maintain space. Don't crowd them.
- Avoid staring. It can increase their paranoia.
- Don't argue with the voices. If you are a caregiver, don't say "There's nobody there." To them, there is someone there. Instead, focus on the feeling. "I can see you're feeling frustrated right now. Do you want to sit down?"
Real Treatments That Work
We’ve moved past the era of just "locking people up." Modern treatment for when a schizophrenic is talking involves a multi-pronged approach.
Antipsychotic medications like Clozapine or Risperidone are the heavy hitters. They work primarily by blocking dopamine receptors in the brain, which seems to "turn down the volume" on the hallucinations. It doesn't always make them go away completely, but it makes them manageable. Like a radio station that’s finally been tuned correctly.

Then there’s CBTp—Cognitive Behavioral Therapy for psychosis. This is a game-changer. It teaches people to recognize the "triggers" for their voices and helps them develop strategies to talk back to the voices in a way that reduces power. Instead of being a victim of the "talk," they become an active participant who can say, "I hear you, but I’m busy right now."
The Avatar Method
There’s some incredible new tech being used in the UK and North America. It’s called Avatar Therapy. A patient works with a therapist to create a digital avatar that looks and sounds like the voice in their head. The therapist then voices the avatar, starting out as mean or demanding, and gradually becoming more supportive as the patient learns to stand up to it.
It sounds like science fiction, but the results are promising. It gives the patient a sense of agency. It turns the invisible enemy into something they can look in the eye.
Navigating the Reality of Schizophrenia
It’s easy to judge what we don’t understand. When we see the outward signs of this illness, we see the "talking," the "muttering," the "gesturing." But we don't see the bravery it takes to live in a world where your own senses betray you.
People with schizophrenia are often incredibly resilient. They are processing two worlds at once: the one we all share, and the one their brain is forcing them to inhabit.
Practical Steps for Support
If you are a friend or family member of someone dealing with this, your role isn't to "fix" the brain chemistry. You can't. Your role is to provide a tether to reality.
- Establish a routine. Predictability lowers stress, which lowers the frequency of hallucinations.
- Encourage "grounding." Sometimes physical sensations—holding an ice cube, listening to actual music with headphones, or gardening—can help drown out the internal noise.
- Focus on the "Small Wins." If they managed to ignore a voice for ten minutes, that’s a victory.
Next Steps for Information and Action
If you or someone you know is experiencing persistent auditory hallucinations, start with a medical evaluation to rule out other causes like sleep deprivation, extreme stress, or neurological issues. Contact a mental health professional who specializes in "First Episode Psychosis" (FEP) programs, as early intervention significantly improves long-term outcomes. For immediate support, organizations like NAMI (National Alliance on Mental Illness) provide peer-led support groups that help demystify the experience of hearing voices and reduce the isolation that often accompanies the diagnosis. Focus on reducing environmental stressors and establishing a consistent medication schedule as directed by a psychiatrist to help stabilize the brain's signaling.
