The present study investigates the intonational tune of syntactically unmarked polar question in Tianjin Mandarin. A production study was conducted to examine the phonological features of the syntactically unmarked polar question (a.k.a intonational yes/no question) tune by comparing against the statement tune. The results show a significant register lift HR and a high floating boundary tone H̥I. The tone shape and tone register played a significant role in how the tunes vary. A tune identification task then further verifies whether the two prosodic features concluded from the production are used in perception. The results showed that both the register difference and the boundary tone made a difference in native speakers' perception in discriminating questions from statements.
Speech fluency affects the effectiveness of speech communications. Previous research has been mostly looking at the fluency performances in L2 and in atypical population. This paper investigates the fluency pattern in news anchor’s natural interview speech, which represents the upper limit of native language fluency, and examines the effect of gender on fluency. We collected a gender-balanced corpus of audio clips of publicly accessible news programs by six native Mandarin speaking news anchors and six native American English news anchors. The total length of interview used in the analysis was 20 min for each language. This study examined six temporal and non-temporal measurements of fluency: temporal measures included speech rate, mean length of run (MLR), mean length of utterance (MLU), and mean length of pauses (MLP); non-temporal disfluency measures included syllable count and disfluency rate. The results showed that male Mandarin speakers had significantly lower MLR, lower MLU, and higher disfluency rates than female Mandarin speakers; no significant gender difference was found in MLP. The English data did not show any gender difference in any measurement. The results indicated that female Mandarin speakers spoke more fluently than male Mandarin speakers, while male English speakers and female speakers were equally fluent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
