Definition of formulaic sequences
According to ''The Canadian Modern Language Review'', formulaic sequences are "fixed combinations ofMorphology and phonology
''Filled pauses'' Filled pauses consist of repetitions of syllables and words, reformulation or false starts where speakers rephrase their speech to fit the representation they best perceive, grammatical repairs, and partial repeats that often involve searching for the right words in one's lexicon to carry across an intended meaning. There are basically three distinct forms for filled pauses: (i) an elongated central vowel only; (ii) a nasal murmur only; and (iii) a central vowel followed by a nasal murmur. Although a schwa-like quality �: appears to be the most commonly used, some speakers consistently using the neutral vowel �:instead, and others use both vowels in the same sentence, depending on the quality of the previous word last vowel. Filled pauses vocalizations may be built around central vowels and speakers may differ in their preferences, but that they do not appear to behave as other words in the language. The lengthening of words ending in a coronal fricative, for instance, could be obtained by prolonging the entire rhyme and/or the fricative only. Most of the time, however, the neutral vowel �:is appended to achieve the desired effect. ''Prolonged pauses'' Similarly to filled pauses, single occurrences of prolonged pauses occurring between stretches of fluent speech, may be preceded and followed by silent pauses, as they most often occur on function words with a CV or V structure. Even though they are not always central, the vowels of such syllables may be as long as the ones observed for filled pauses. ''Retraced and unretraced restarts'' Riggenbach's 1991 study of fluency development in Chinese learners of English had an analysis of repair phenomena, which included retraced restarts and unretraced restarts.Riggenbach, H. (1991)Semantics and pragmatics
The semantics of formulaic language have often been debated on, and to date, there lacks a consensus on whether or not filler words are intentional in speech and whether or not they should be considered as words or if they are simply side effects of difficulties in the planning process of speech by speakers. Bailey & Ferriera's (2007) paper found that there is little evidence to suggest that the use of filler words are intentional in speech and that they should not be considered as words in the conventional sense. Filler words consist of "Non-lexical fillers" and "Lexical fillers". "Non-lexical fillers" are recognized as fillers that are not words and "Lexical fillers" are recognized as fillers that are words and both types of fillers are thought to contain little or no semantic information. However, some filler words are used to express certain speech acts. "Yeah", a "Lexical filler", is used to give affirmation, introduce a new topic, shows speaker's perception and understanding, and occurs after a speech management problem when the speakers does not how to continue their speech. Fillers like "Mmmm", a "Non-lexical filler", and "Well", a "Lexical filler", are also said to signal listener's understanding of the information provided. Research has shown that people were less likely to use formulaic language in general topics and domains they were more well-versed in, because they were more adept at selecting the appropriate terms. To date, there is insufficient research done to say if fillers are a part of integral meaning, or if they are aspect of performance, but we can say that they are useful in facilitating information for the listener.Syntax
Formulaic language is more likely to occur at the beginning of utterance or phrase and the reason is because it is presumed that there is a greater demand on planning processes at these junctures.Schnadt, M. J., and M. Corley. submitted. Buying time in spontaneous speech: How speakers accommodate lexical difficulty. Features of formulaic language, like filled pauses or repetitions, are most likely to occur immediately prior to the onset of a complex syntactic constituent. Filled pauses are also likely after the initial word in a complex constituent, especially after function words. Therefore, listeners might be able to use the presence of a recent filled pause to predict that an ambiguous structure, and this trait is in favor of a more complex analysis . There are several different types of formulaic language. One type is relatively universal, often transcending differences in language and to some degree culture. Simple fillers like "Uhm", "Uh", or "Er" are used by many different people in many different settings. For the most part, these types of fillers are considered innocuous, and are often overlooked by listeners, as long as they are not utilized so often that they overshadow the remainder of the conversation. Other forms of formulaic language are ingrained within specific cultures, and in fact are sometimes considered an identifying characteristic of people who share a particular religion, or live in a specific geographical region. Along with accents, formulaic language of this type is sometimes considered colorful and somewhat entertaining. Writers often make use of this type of speech to give the characters in their writings additional personality, helping to make them unique. ''Fluency'' The study conducted by Dechert (1980) that investigated the speech performance of a German student of English revealed that there is a tendency for speech pauses to be situated at breaks that are consistent with "episodic units".[Dechert, HW. (1980). Pauses and intonation as indicators of verbal planning in second-language speech productions: Two examples from a case study. In Dechert, HW & Raupach, M. (Eds.), Temporal variables in speech (pp. 271-285).] Dechert (1980) found that the more fluent utterances exhibited more pauses at those junctures and lesser within the "episodic units", leading him to posit that the study subject was able to use the narrative structure to pace his own speech with natural breaks in order for him to scout for the words and phrases that are to follow subsequently. Through the comparison of the story retelling utterances collated of second language learners, Lennon (1984) discovered notable disparities in the distribution of pauses between recounting in the research subjects' first and second languages respectively. ennon, P. (1984). Retelling a story in English. In HW, Dechert, D. Mehle, 8c M. Raupauch (Eds.), Second Language Productions (pp. 50-68). Turbingen: Gunter Narr Verlag./ref> The study found that all of the pauses were found to be located either at clause breaks or following nonintegral components of the clause, without pauses within the clauses. On the other hand, the narrators who spoke using their second language exhibited different patterns, with a higher frequency of pauses occurring within the clauses, leading to the conclusion posited by Lennon to be that the speakers seem to be "planning within clauses as well as in suprasegmental units", and hence, the occurrence of pauses within clauses and not at the intersection of clauses could well be an indicator distinguishing fluent and confluent speech.Discourse features
Cognitive load
Speech rate
Formulaic phrases are uttered more quickly than comparable non-formulaic phrases. Speech rate is closely related to cognitive load. Depending on the cognitive load, the rates of a speaker's utterances are produced either faster or slower, in comparison to a fixed speaking rate which happens usually. For example, speech rate becomes slower when having to make choices that are not anticipated, and tend to accelerate when words are being repeated. In fast conditions, cognitive processes that result in a phonetic plan, fail to keep up with articulation, and thus, the articulation of the existing plan is restarted, resulting in the repetition of words which is more likely to happen but no more likely than fillers.Frequency of words
In Beattie and Butterworth's (1979) study, low frequency content words and those rated as contextually improbable were preceded by hesitations such as fillers. Speakers, when choosing to use low frequency words in their speech, are aware, and are more likely to be disfluent. This is further supported by Schnadt and Corley where they found that prolongations and fillers increased in words just before multiple-named or low frequency items.Domain (addressor vs. addressee)
Humans are found to be more disfluent overall when addressing other humans than when addressing machines. More instances of formulaic language is found in dialogues than in monologues. The different roles the addresser played (such as a sister, a daughter or a mother) greatly influences the numbers of disfluencies, particularly, fillers produced, regardless of length or complexity.Functions
Comprehension cues
There is a common agreement that disfluencies are accompanied by important modifications both at the segmental and prosodic levels and that speakers and listeners use such cues systematically and meaningfully. Thus they appear as linguistic universal devices that are similar to other devices and are controlled by the speaker and regulated by language specific constraints. In addition, speech disfluencies such as fillers can help listeners to identify upcoming words. While formulaic language can serve as a useful cue that more is to come, some people do develop an unconscious dependence on these filler words. When this is the case, it is necessary to correct the problem by making the speaker be aware of their over-reliance on formulaic language production and by training the person to make more efficient use of other verbal strategies. As the individual gains confidence and is less apt to have a need for filler words, the predilection toward formulaic language is then able to gradually diminish. A study done by Foxtree (2001) showed that both English and Dutch listeners were faster to identify words in a carrier sentence when it was preceded with an "Uh" instead of without an "Uh", which suggested that different fillers have different effects as they might be conveying different information. Fischer and Brandt-Pook also found out that discourse particles mark thematic breaks, signal the relatedness between the preceding and following utterance, indicate if the speaker has understood the content communicated, and support the formulation process by signalling possible problems in speech management. While fillers might give listeners cues about the information being conveyed, Bailey & Ferreira's study made a distinction between "Good Cues" and "Bad Cues" in facilitating listener's comprehension. A "Good Cue" leads the listener to correctly predict the onset of a new constituent (Noun Phrase, Verb Phrase), whereas a "Bad Cue" leads the listener to incorrectly predict the onset of a new constituent. "Good Cue" make it easier for listeners to process the information they have been presented while "Bad Cue" make it harder for listeners process the relevant information. There is strong empirical evidence that speakers use formulaic language in similar ways across languages and that formulaic language plays a fundamental role in the structuring of spontaneous speech, as they are used to achieve a better synchronization between interlocutors by announcing upcoming topic changes, delays related to planning load or preparedness problems, as well as speaker's intentions to take/give the floor or to revise/abandon an expression he/she had already presented.Communicative goals
A study conducted by Clark and Foxtree (2002) mentioned that parts of formulaic language, such as fillers, serve a communicative function and are considered integral to the information the speaker tries to convey, although they do not add to the propositional content or the primary message. Instead, they are considered part of a collateral message where the speaker is commenting on her performance. Speakers produce filled pauses (e.g. "Uh" or "Um") for a variety of reasons, including the intention to discourage interruptions or to gain additional time to plan utterances. Another communicative goal includes the attention-impelling function, which explores another purpose of hesitation forms as being to dissociate oneself slightly from the harsh reality of what is to follow. With the use of a beat of time filled with a meaningless interjection, uncommitted people who are "into distancing" make use of such formulaic language to create a little distance between themselves and their words, as if it might lessen the impact of their words. However, not all forms of formulaic language are considered appropriate or harmless. There are examples of formulaic language production that lean towards being offensive, for instance, the use of anything considered to beNeurological basis
