What is Fluency? • Broad vs. narrow definition (Lennon, 1990) • Broad: general oral proficiency • Narrow: speed and smoothness of oral delivery • The rapid, smooth, accurate, lucid, and efficient translation of thought or communicative intention into language under the temporal constraints of on-line processing (Lennon, 2000, p. 26) • Fluency is • a characteristic of the speaker’s speech: performance fluency • a characteristic of the speaker: cognitive fluency (Segalowitz, 2000)
Characteristics of a Fluent Speaker • Oral production poses greater working memory demands than written production • Fluent speech requires automatization of processes (e.g., Lennon, 2000; Segalowitz, 2000; Towell, Hawkins & Bazergui, 1996) • WM demands are also lowered by the use of prefabricated chunks of language, such as formulaic sequences (FSs): • FSs = Continuous or discontinuous sequences of words, which are, or appear to be, prefabricated (cf. Wray, 2002, p. 9)
Characteristics of Fluent Speech • There are many measures of fluency, including: • Length of fluent runs • Number of syllables between pauses • Length of pauses • Phonation/time ratio • % of time filled with speech • Articulation rate • Syllables per minute (Towell et al., 1996)
Formulaic Sequences and Fluency • Formulaicity aids the speaker’s production (Wray, 2000): • Manipulates information (e.g., mnemonics) • Buys time for processing and provides textual bulk • Creates a shorter processing route • Organizes, and signals the organization, of discourse • If FSs are chunks, they can be produced without pauses, contributing to the “smoothness” of speech (cf. Wood, 2006)
How Formulaic Sequences are Learned • Wray (2002): L1 is learned holistically, but (older) L2 learners process FSs at the word level: • Incorrect formulaic sequence use is a result of constructing the sequence from parsed speech • Towell et al. (1996): Language is proceduralized into grammatically correct chunks. If the structure of a FS is incorrect, it has not been proceduralized. • However, L2 speaker often use many idiosyncratic, ungrammatical sequences (Oppenheim, 2000) • So L2 learners need to use formulaic sequences repeatedly to be able to retrieve them as chunks.
Research Questions • Does a pretraining of formulaic sequences lead to an increase in their use in subsequent speaking activities (fluency training)? • If so, does fluency increase? • Effortless use of formulaic sequences frees up cognitive resources for sentence structure planning, which in turn may lead to an overall more fluent performance in terms of speed and pausing patterns
Participants • 34 ESL students, low and high intermediate • 16 female, 18 male • Age: average 26 years; range 18-44 • L1s: Arabic (10), Chinese (6), Korean (16), Spanish (1), Thai (1) • Enrolled in Speaking courses at the English Language Institute of a large university in the U.S.
Selection of Formulaic Sequences • From Nattinger & DeCarrico (1992) • Typical for spoken discourse • Learnability: familiar words; transparent meaning; length • Usefulness for fluency: length • Discourse function can be elicited • Not used yet; not taught
Formulaic Sequences Pretraining One 50-minute session • Listening: One-minute speech that contained the ten formulaic sequences (“common phrases”) • Three comprehension questions • Fill-in-the-blanks; blanks are words from formulaic sequences • Check answers, with focus on function words • Function: Categorizing the sequences according to meaning/function
Formulaic Sequences Pretraining (cont.) • Grammatical structure and intonation: Explanation and modeling of the relationship between grammatical structure and intonation • Speaking: One to two minutes about a given topic. Use five sequences; a partner checks off the sequences from the list. Then switch roles.
Experiment: Procedures • Pretest • Pretraining formulaic sequences • Control condition: regular classes • Fluency training • 4/3/2 task: Speak about a topic for 4, 3, and 2 minutes • Three times over 2 weeks: Session A, B, C • Posttest (4-7 days later) • Delayed posttest (31-35 days later) • Computer lab
Results:Use of Formulaic Sequences • Most students attempted to use at least one formulaic sequence (max. 20 students) • Session A total: 12 students (avg. 5.7 attempts) • Session B total: 15 students (avg. 7.3 attempts) • And one student in the No Pretraining condition had one attempt • Session C total: 15 students (avg. 4.9 attempts) • Four out of five students who did not use any trained formulaic sequences, did use more untrained sequences
Results:Formulaic Sequences and Fluency Results from Session B only: most FSs per speech • Students who used more trained formulaic sequences tended to have longer pauses: • 2-min. speech: r = .315, p = .074 (trend) • Lower fluency • However, their fluent runs were longer (but only for FSs with grammatical errors) • 2-min. speech: r = .408, p = .018 • 3-min. speech: r = .414, p = .015 • Higher fluency • The trained formulaic sequences seem not to be used automatically; students need to pause to use them
Results:Post-tests • Students used hardly any formulaic sequences in the immediate and delayed posttests • Both groups: no trained sequences • Pretraining group: 0.24 and 0.29 untrained sequences per student • No Pretraining group: 0.21 and 0 untrained sequences per student • However, the teachers reported the students did use the sequences in class
Results:Untrained Sequences • Untrained sequences were included in the analysis only if: • they were used by at least fivestudents, each in at least two speeches • they had a function in the text, e.g., fluency device, exemplifier • Untrained formulaic sequences: • In my opinion – First of all • For example
Results:Untrained Sequences • In general, students in the Pretraining condition used more untrained sequences than students in the No Pretraining condition • More students used untrained sequences • These students used a greater number of untrained sequences • Effect on the use of formulaic sequences and discourse organizers in general
Results:Formulaic Sequences and Fluency (2) • Again, results from Session B only • Correlations between # of untrained sequences and mean length of fluent runs: • 3-min. speech: r = .356, p = .039 • 2-min. speech: r = .468, p = .006 • Correlations between # of untrained sequences and phonation/time ratio: • 3-min. speech: r = .380, p = .027 • 2-min. speech: r = .369, p = .035 • No correlations found in 4-min. speech • Due to length of speech? Higher fluency Higher fluency
Results:Correct and Incorrect Form • Trained formulaic sequences were often used incorrectly (form errors) • E.g., I give you an example, What I'm trying to say that, Seems to me • Accuracy: • Session A: 39%; B: 23%; C: 25% • But high standard deviations: 41, 27, 35 resp. • Untrained formulaic sequences were mostly used correctly
Results: Summary • Most students attempted to use some trained formulaic sequences • Mixed effects on fluency • Often with grammatical errors • Pretrained students also used more untrained sequences • Some effect on fluency • Very few sequences used on post-tests
Discussion • RQ1: Yes, the pretraining led to an increase in the use of formulaic sequences in speaking activities • However, students often used them incorrectly • Some students used them more than others • There was little transfer to other speaking tasks • RQ2: Mixed effect on fluency. The use of trained formulaic sequences led to longer fluent runs (=fluency) but also longer pauses (=dysfluency) • The trained formulaic sequences were probably not stored as chunks, and retrieval was not automatized • Role of frequency (Ellis, Simpson-Vlach & Maynard, 2008)
Discussion • Raising awareness of formulaic sequences led to an overall increase in their use • Even without training, students used some basic formulaic sequences with high accuracy • It seems that the use of formulaic sequences was not effortless, and had a mixed effect on fluency • The form errors suggest that the students had learned formulaic sequences at the word level, and did not store and retrieve them as chunks (cf. Towell et al., 1996; Wray, 2002)
Future Research • Students used few formulaic sequences. Can we find better ways to teach formulaic sequences? • To improve fluency • To improve accuracy • To improve long-term effects • Analyze the correct use of the sequences (so far, only analyzed form) • Function in the text • Why were some sequences were “more popular” than others?

Characteristics of fluent speech • There are many different ways in which fluency has been measured: • Length, number, position of pauses • Articulation rate (words/syllables per minute) • Length of fluent runs (number of words/syllables between pauses) • Phonation/time ratio (% of time filled with speech) • Number of hesitations (I like to to to run) • And more…
Characteristics of Fluent Speech • There are many measures of fluency, including: • Length of fluent runs • Number of syllables between pauses • Length of pauses • Phonation/time ratio • % of time filled with speech • Articulation rate • Syllables per minute • Increase in A without a trade-off with B and C indicates procedularization (automatization) of knowledge (Towell et al., 1996) • D is a measure of speed, not proceduralization
