Speech Misperception (IMAGE) Society for Neuroscience Caption Misperception of speech results from a weak representation of the difference between what we expect to hear and what is actually said, according to a human neuroimaging study published in JNeurosci. The research provides new evidence for how the brain creates perceptual illusions when speech is degraded at cocktail parties, in song lyrics or for older listeners.
