<br/>   abstract  = {Rhythmic characteristics of speech vary between native and non-native
speakers. Studies comparing the rhythmic properties of L1 and L2 speech based on
rhythm metrics have shown that this relationship is far from straightforward. It seems
evidently the case that the difference between native and non-native speech is a
complex interaction of a variety of rhythmic cues (duration, F0 and intensity). In this
study we extended the durational domain by F0 and tested whether metrics
combining duration and F0 (henceforth combined measures) could better account for
the rhythmic differences between L1 and L2 speech. To test this, 5 native Mandarin
speakers and 5 Italian learners of Mandarin recorded The North Wind and the Sun in
Mandarin. Besides, each Italian speaker also recorded the same text in Italian. Each
sentence in L1-L2 Chinese and in L1 Italian was segmented into syllables. We
calculated duration- and F0-based metrics (Δsyllable duration/F0; r-PVI syllable
duration/F0; Varco syllable duration/F0; nPVI syllable duration/F0), as well as
combined metrics (Δcombined, Varco combined, rPVI combined and nPVI
combined). Results show that measures taking syllable duration and F0 separately do
not differentiate consistently between L1 and L2 Chinese, while combined metrics
reflect more systematically the variability pattern between L1 and L2 Chinese speech
rhythm. More research is, however, needed to explore the significance of combined
metrics as opposed to duration- and F0-based measures for the perceived rhythmic
differences between L1 and L2 speech.},
