 nonnative speakers of English are slower than that of native English speakers' (Guion et al., 2000). In this study, the main factor of the slower speech rate for the Italian and Korean accented English was the durations of the vowels and sonorant consonants
Sonorant
In phonetics and phonology, a sonorant is a speech sound that is produced without turbulent airflow in the vocal tract; fricatives and plosives are not sonorants. Vowels are sonorants, as are consonants like and . Other consonants, like or , restrict the airflow enough to cause turbulence, and...

 (Guion et al., 2000). Another source of the slower speech rate in L2 speech is that L2 speakers tend to not reduce function words, such as "the" or "and," as much as native speakers (Aoyama and Guion, 2007). The generally slower speech rate in L2 speech is correlated with the degree of perceived foreign accent
