Stuttering also called stammering or childhood-onset fluency disorder is a speech disorder that involves frequent and significant problems with normal fluency and flow of speech. People who stutter know what they want to say, but have difficulty saying it. For example, they may repeat or prolong a word, a syllable, or a consonant or vowel sound. Or they may pause during speech because they've reached a problematic word or sound.
