This study confirms previous acoustic findings that yes-no questions and declarative questions have a higher register than declarative sentences. However, our perception tests show that in the formation of Mandarin questions intonation is not as important as in French. For yes-no questions with question particles, the question particles play the main role. The subjects perceived the yes-no questions without particles and the declarative questions as showing surprise on the part of the speaker, or as surprised questions. The study suggests that in Mandarin, question intonation and surprise intonation are one and the same.
This study examines the realization of modified tones (the tones that a syllable carries in a non final position) in Min-nan by means of instrumental and statistical analyses. Previous studies reported that the modified tons 1'() and 2' () 4' () and 6' ( ended with a glottal stop), 5' () and 7' ( ended with a glottal stop) are the same tones respectively. Such fact was observable only at Fo level and duration level in the present study. Significant differences in intensity were observed, especially between modified tones 4' and 6'b.
