Outline of talkPrevious analyses of repairA new classification of repairA study of repair in L1 and L2 speechHow repair types relate to speech rateHow repair differs in L1 and L2 speech
Temporal & other measures of fluency Articulation rate Pause time, frequency (MLR), duration Pause distribution Repair – frequency & number of words [Coherence and cohesion]
Combined measures of fluency
Speech rate (SR)= articulation rate (AR), pause time
Pruned speech rate = AR, pause time, repair
pruned speech = speech minus repair & filled pauses
Lennon 1990Repair frequencyPruned speechRiggenbach 1991Retraced and unretraced false startsHow much rejected?Freed 1995Frequency of repetitions, reformulations,
corrections, partial repeat of word
Tavakoli, P. and Skehan, P. (2005)
Frequency of repetition, reformulation, false start, substitution.
“The repair fluency group loads together consistently, and separately from other aspects of fluency suggesting that a concern to modify utterances on-line is somewhat distinct from a capacity to organise speech in real time.”
Maclay and Osgood 1959
Repetition that non-significant semanticallyFalse starts: retraced (reformulations) and non-
retracedRepetitions of form words, before lexical word. Retraced false starts of lexical items before
lexical items
Negative correlation between SR and combined total hesitations
Olynyk, M., A. d’Anglejan and D. Sankoff (1990)
Investigation of “speech markers”: filled pauses, transitions, repetitions, repair
conversions, cut-offs
Progressives (prepositioned repair)Regressive (postpositioned, after the repair)
High fluency speakers have more repeats and transitions, low fluency speakers more repair conversions, cut-offs.

Learner Data: 17 Taiwanese university studentsWork in pairsEnglish language and literature dept.1st and 8th semestersPicture story monologue – 2 mins eachDiscussion dialogue – 4-5 mins: e.g.
prioritise qualities of friends.
Data
Native speaker data: 6 native speakers aged 19-30.Same tasks, in pairs.
Processing & AnalysisTranscriptions using ”Transcriber”. Fluency measurement.Repair tagging for each occurrence of
repair.
Fluency analysisArticulation rate, speech rate, pruned
speech ratePause frequency, pause time, mean length
of pause, mean length of runPause distribution – between clauses,
between constituents, between words.Repair: pruned speech rate, percentage of
pruned speech
ExternalBetween clausesAt beginning/ end of clauseInternalWithin clausesAfter clause has startedNumber of wordsWords rendered unnecessary by repair
Repetitionexactly the same wordsno rhetorical or emphatic effectReformulationlexis, grammar, lexis and grammarsame start, lexis or grammarFalse startnew start, new lexis and grammar
Repetition before lexical or form wordsSeach for lexis or grammare.g. lexis|so he ‘s made up his mind ::{to
#####εεε} to lose weight.
e.g. form{and they are they are} #####they are
very scared{maybe t-h-e-y} ####maybe they didn ‘t
have anything
Reformulation – change of grammar or lexis or both
Grammar = form: morphology, syntax, form words (articles, prepositions)
Lexis = meaning: content wordsExpression = new word(s), new structure(s)
Examples:Grammar but he still {keeps on keep on} kept on
walkingLexis and .......{εεε} the robber told {one of the
bank ####εε} one of the workersExpression maybe they didn ‘t have anything to εε they}
maybe they ,,,,didn ‘t have the ///right knowledge|
Repair tagging: E-3-RP-L, I-2-RF-G1. External/ Internal 2. No. of words 3-4. Repetition (RP), reformulation (RF),
false start (FS)5. Repetition followed by: lexical word (L),
form word (F), nothing (X).Reformulation of lexis (L), grammar (G) or
both: expression (E)False start ends with lexical (L) / form (F)
word.
Pearson correlations of repair measures with learners' speech rate:
All repair frequency= .56 – no. of words= .65Repetition – frequency= .20 - no. of words= .53Reformulation – frequency = .56 - no. of words= .61Mean length of repair= .32
External repair frequency= .61 -words= .65Internal repair frequency= .27 -words= .46Repetition before lexis -words= .55 before form -words= .38Reformulation of lexis - frequency= .40 -words= .60Reformulation grammar -frequency= .294 -words= .24
No reformulation of grammar
Negative correlations all repair: SR = -.26 repetition (words): SR =-.53
Internal repair correlates negatively with speech rate, but external does not correlate significantly.
Native speaker - non-native speaker repair means
% repaired words: 14.7 3.9% repeated words: 6.4 1.8% reformulated words: 6.7 1.5% false starts: 1.5 0.6
Non-native speaker repair examples:
|{εεεεε .......it is a bank}E4RFGit was a bank|
|so they could find out ....::{εεεεε who the robber is}E4RFG#######who the robbers are|
|{a-n-d he find}E2RFE ######a-n-d {h-e want ::to find a job εεε}E6RPF he want ::to ////find a jobs to do|
Examples:|and it was beginning ::to show on {his}I1RPL
{εεε} his tummy|.......|a couple of {er old lady}I2RFL older
ladies ,,,,,looking quite smart||{and it}E2RPL and {it s- e-}E3FSF the weather
{changed}I1RFL took a bit of a change for the worse|
ConclusionsFor learners, more repair correlates with slower speech rates.
For native speakers, more repair correlates with faster speech rates.
Repetition before lexical/ form words: no significant difference.
Reformulation of grammar: absent from NS, low correlation with speech rate for learners.
Conclusions
ConclusionsRepair frequency and repair extent/ no. of
words behave differently.External repetition more significant than
internal for learners.False start & reformulation of expression
could be brought together.More data & analysis required...
