Sleep-talking or somniloquy refers to talking or making sounds during sleep and is usually found in young children.


There may not be any cause for sleep-talking or it may be due to certain conditions like:

  • Fever
  • REM sleep behavior disorder
  • Sleepwalking
  • Sleep terrors
  • Substance abuse
  • Emotional stress
  • Sleep deprivation


  • Speech or sounds during sleep
  • No memory of it on waking up


Sleep-talking is harmless and does not require treatment. In cases due to underlying medical conditions, those conditions need to be treated.


There is no specific prevention for sleep-talking.
