Speech disfluency
（重定向自Speech disfluencies）
A speech disfluency, also spelled speech dysfluency, is any of various breaks, irregularities (within the English language, similar speech dysfluency occurs in different forms in other languages), or non-lexical vocables that occurs within the flow of otherwise fluent speech. These include false starts, i.e. words and sentences that are cut off mid-utterance, phrases that are restarted or repeated and repeated syllables, fillers i.e. grunts or non-lexical utterances such as "huh", "uh", "erm", "um", "well" and "like", and repaired utterances, i.e. instances of speakers correcting their own slips of the tongue or mispronunciations (before anyone else gets a chance to). "Huh" is claimed to be a universal syllable.
