In spoken language analysis, an utterance is a continuous piece of speech, by one person, before or after which there is silence on the part of the person. In the case of spoken languages, it is generally, but not always, bounded by silence. In written language, utterances only exist indirectly, through their representations or portrayals. They can be represented and delineated in written language in many ways.
In spoken language, utterances have several characteristics such as paralinguistic features, which are aspects of speech such as facial expression, gesture, and posture. Prosodic features include stress, intonation, and tone of voice, as well as ellipsis, which are words that the listener inserts in spoken language to fill gaps. Moreover, other aspects of utterances found in spoken languages are non-fluency features including: voiced or unvoiced pauses (e.g. "umm"), tag questions, and false starts, or when someone begins uttering again to correct themselves. Other features include fillers (e.g. "and stuff"), accent/dialect, deictic expressions (utterances such as "over there!" that need further explanation to be understood), simple conjunctions ("and", "but", etc.), and colloquial lexis (everyday informal words).
