A stutter, also known as stammering, is a speech disorder characterized by disruptions in the flow of speech. These disruptions can include repetitions of sounds, syllables, or words, as well as prolonged sounds. Stuttering can affect people of all ages, but it often begins in childhood. The exact cause is not fully understood, but it may involve genetic, neurological, and environmental factors. People who stutter may experience anxiety or frustration when speaking, which can impact their communication and social interactions. Treatment options include speech therapy, which focuses on improving fluency and confidence, and support groups that provide encouragement and understanding. Early intervention can be beneficial for those affected by stuttering.
