In spoken language analysis, an utterance is the smallest unit of speech. It is a continuous piece of speech beginning and ending with a clear pause. In the case of oral languages, it is generally but not always bounded by silence. Utterances do not exist in written language, only their representations do. They can be represented and delineated in written language in many ways. In spoken language analysis, an utterance is the smallest unit of speech.

Utterances do not exist in written language, only their representations do. They can be represented and delineated in written language in many ways. In oral/spoken language utterances have several features including 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/un-voiced pauses (like 'umm'), tag questions, and false starts when someone begins their utterances again to correct themselves. Other features include: fillers ('and stuff'); accent/dialect; deictic expressions, which are utterances like 'over there!' which need further explanation to be understood; simple conjunctions ('and,' 'but,' etc.); and colloquial lexis which are everyday informal words. Utterances that are portrayed in writing are planned, in contrast to utterances in improvised spoken language. In written language there are frameworks that are used to portray this type of language. Discourse structure (which can also be found in spoken language) is how the conversation is organized, in which adjacency pairs - an utterance and the answer to that utterance - are used. Discourse markers are used to organize conversation ('first,' 'secondly,' etc.). Lexis denotes the words being used in a text or spoken; these words can create a semantic field. For example, a semantic field of love can be created with lexical choices such as adore, admire, and care. Grammar/syntax is another feature of language in general but also utterances, and pragmatics means that when utterances are spoken or written the meaning is not literal, as in sarcasm. An utterance which is found in spoken and written language as in a script has several characteristics. These include paralinguistic features which is a feature of communication that doesn't involve words but is added around an utterance to give meaning. Examples of paralinguistic features include facial expressions, laughter, eye contact, and gestures. Prosodic features refer to the sound of someone's voice as they speak: pitch, intonation and stress. Ellipsis can be used in either written or spoken language, when an utterance is conveyed and the speaker omits words because they are already understood in the situation. For example: A: Juice? B: Please. A: Room temperature? B: Cold. Non-fluency features also occur when producing utterances. As people think about what to say to while speaking, there are errors and corrections in speech. For example, voiced/un-voiced pauses which are 'umm,' 'erm,' etc. in voiced pauses and in transcripts un-voiced pauses are denoted as (.) or (1) relating to the amount of time of the pause. Tag questions are also a part of non-fluency features; these are used by the speaker to check if the listener understands what the speaker is saying. An example is 'Do you know what I mean?' False alerts occur when the speaker is voicing an utterance but stops and starts again, usually to correct themselves. Fillers usually give the speaker time to think and gather their thoughts in order to continue their utterance; these include lexis such as, 'like,' 'and stuff,' Accent/dialect is also a characteristic included in utterances which is the way the words are voiced, the pronunciation and the different types of lexis used in different parts of the world. Deictic expressions are utterances that need more explanation in order to be understood, like: 'Wow! Look over there!' Simple conjunctions in speech are words that connect other words like 'and,' 'but,' etc. Colloquial lexis is a type of speech that is casual in which the utterance is usually more relaxed. The development of utterances in children is facilitated by parents, adults, or any other guardian the child has growing up. Studies have indicated that this development of utterances is affected by the parent, adult, or guardian's socioeconomic status (SES). It has been shown that children have larger vocabularies and learn new words more quickly during early childhood from parents with a high education and higher SES status, while children with less educated parents and lower SES status have a smaller vocabulary and a slower growth in their vocabulary skills (Arriaga, Fenson, Cronan & Pethick, 1998; Hart & Risley, 1995; Hoff, Laursen & Tardif, 2002; Hoff-Ginsberg, 1991; Lawrence & Shipley, 1996; Ninio, 1980). This correlation is due to the fact that more educated parents use more lexis when speaking to their children as opposed to parents that are less educated (Hart & Risley, 1995; Hoff, 2003 a; Huttenlocher, Vasilyeva, Waterfall, Vevea & Hedges, in press). Hoff conducted an analysis that shows support for this correlation in 2003 which shows that the mean length of utterance and vocabulary of mothers who talk to their children is related to their SES status and thus child vocabulary development. High-SES mothers use longer utterances when talking to their children and a wider variety of words. They also spend more time talking to their children. Low-SES mothers use shorter utterances and a smaller vocabulary. As a result, children with more educated parents have larger vocabularies (Hoff, 2003). In child-directed speech, utterances have several additional features. For example, the phonology in child-directed speech is different: Utterances are spoken more slowly, with longer pauses in between utterances, higher pitches, etc. The lexis and semantics differ, and a speaker uses words suited for children, 'doggie' instead of 'dog,' for example. The grammar is simpler, repetitive, with less use of verbs and adjectives. There is a greater use of one word utterances and the pragmatics uses supportive language like expansions and re-casting.
