Abstract

While utterance fluency measures are often studied in relation to perceived L2 fluency and proficiency, the effect of creaky
voice remains ignored. However, creaky voice is frequent in a
number of languages, including Finnish, where it serves as a cue
for phrase-boundaries and turn-taking. In this study we investigate the roles of creaky voice and utterance fluency measures
in predicting fluency and proficiency ratings of spontaneous L2
Finnish (F2) speech. In so doing, 16 expert raters participated in
assessing narrative spontaneous speech samples from 160 learners of Finnish. The effect of creaky voice and utterance fluency
measures on proficiency and fluency ratings was studied using
linear regression models. The results indicate that creaky voice
can contribute to both oral proficiency and fluency alongside
utterance fluency measures. Furthermore, average duration of
composite breaks – a measure combining breakdown and repair phenomena – proved to be the most significant predictor
of fluency. Based on these findings we recommend further investigation of the effect of creaky voice to the assessment of
L2 speech as well as reconsideration of the utterance fluency
measures used in predicting L2 fluency or proficiency
