Hearing voices—technically known as auditory verbal hallucinations (AVH)—is the experience of hearing speech when no actual external speaker is present.
While often associated with mental health conditions such as Schizophrenia, hearing voices can also occur in many other situations.
These include:
- Extreme stress
- Trauma
- Sleep deprivation
- Hearing loss
👉 This means hearing voices is not always a sign of illness.
🧠 How the Brain Processes Voices
Our brain constantly creates a mental model of the world.
It helps us tell the difference between:
- External sounds (someone speaking to you)
- Internal thoughts (your inner voice or memories)
Reality Monitoring
This process is called reality monitoring.
- It allows us to recognise what is real (outside)
- And what comes from our own mind (inside)
👉 When this system has a “glitch”, the brain may:
- Mistake a thought or memory
- For an external voice
What Brain Scans Show
Brain imaging studies show that when people hear voices:
- Areas involved in real speech processing become active
- Especially the left temporal lobe
👉 This suggests the brain is processing the voice as if it is real speech
🌍 Common Causes and Contexts
Hearing voices is more common than many people think and can happen in different contexts.
Mental Health Conditions
