摘要： The purpose of this study was to investigate how vocal attack time (VAT) varies when young adults articulate the three vertex vowels in Mandarin Chinese at five linguistically unconstrained pitch levels. Sound pressure (SP) and electroglottographic (EGG) signals were recorded simultaneously from fifty-three male and fifty-three female subjects saying sustained /A/, /i/ and /u/ at five equally spaced pitch heights, each being higher than the preceding one. Then analyses of means, variance and correlation were performed to explore the relationships of VAT/pitch levels and VAT/vowels. Findings were: As mean STs (semitone) increase linearly from levels one to five, mean VATs decrease nonlinearly in a big group of subjects but increase nonlinearly in a small group of them. Based on the body-cover model of F0 control, data here lead to the guess that different people incline to use different strategies in increasing pitch height. When males, females and males plus females are considered as a whole, average STs and VATs tend to be positively correlated among the three vertex vowels.

摘要： This paper presents the data on the anticipatory coarticulation of C2 and V2 on V1 in V1#C2V2 sequences in Standard Chinese. Electropalatographic measures and F2 trajectory were obtained to define the articulatory and F2 targets for V1 as well as the displacement for articulatory and F2 transition of V1. Results show that the articulatory target is affected only by C2 place, while C2 place, C2 manner, and V2 show combined effect on the articulatory and F2 displacement of V1. Lip rounding associated with V2 is found to affect the F2 target and F2 transition of V1.

摘要： This paper presents an electropalatographic (EPG) and acoustic study of prosodic boundaries effect on the domain-initial segments in Standard Chinese.1 Two speech sounds, namely, the voiceless unaspirated alveolar stop /t/ and the high front vowel /i/, were studied to examine the domain-initial strengthening in both spatial and temporal dimensions. The articulatory and acoustic parameters of the speech sounds were compared in initial positions of five prosodic constituents in Standard Chinese, namely, a Syllable, a Foot, an Immediate Phrase, an Intonational Phrase, and an Utterance. The results show that: (1) the production of the domain-initial consonantal gesture was prosodically encoded. The linguopalatal contact and the seal duration varied as a function of the prosodic boundary strength. The linguopalatal contact was dependent on the seal duration in a nonlinear fashion. Of the acoustic properties of the domain-initial stop, the total voiceless interval and voicing during closure were found to be reliable acoustic correlates that mark the hierarchical structure of the prosody. (2) At the release moment of the domain-initial stop, no consistent pattern was found to support the domain-initial strengthening. The linguopalatal contact of the vowel immediately following the domain-initial consonant did not show a clear trend of domain-initial strengthening; however, the phonatory features of vowels were indicative of pitch reset at major prosodic boundaries. These indicate that the domain-initial strengthening is restricted on the segment immediately following the boundary. In conclusion Standard Chinese strengthens the phonetic features of the domain-initial segments as a function of boundary strength, which serves as an important way to mark prosodic structure in Standard Chinese.

摘要： This research studies the features of chest and abdominal breathing between reciting and chanting Chinese poems of different styles. Eight participants were recruited to recite and chant 85 modern style poems (近體詩) and 39 Song poems(宋詞). The chest and abdominal breathing signals as well as speech signal were recorded simultaneously. Programs for breathing analysis have been written to extract parameters such as breathing reset amplitude, time of inhale phase, and slope of exhale phase. The results show that the poem chanting has a larger depth of breathing and amount of breath, and more frequent exhalations compared with the poem reciting. In both poem reciting and chanting, the pause and declination of chest breathing is closely correlated with the prosodic boundaries. The major function of chest breathing in speaking is to keep the extended state of the chest and provide enough breath for articulation and chest resonance. And the function of abdominal breathing is to provide stable sub-glottal pressure through contraction of abdominal muscle and diaphragm, controlling continuous airflow to produce continuous sound.

摘要： The purpose of this research was to investigate the association of vocal attack time (VAT) and tones in speakers of Mandarin Chinese, and to explore how tones initiated at different pitch levels affected VAT. SP and EGG signals were synchronously re corded from 72 young undergraduates or postgraduates (42 females and 30 males) while they were reading aloud a wordlist of 50 disyllabic words at their most comfortable pitch, loudness and rate. VAT measures revealed three findings . (1) Vocal attack time s hows no significant difference between the common yangping and the yangping derived from shangsheng . This, from a physiological perspective, supports the argument that the tone sequence 3 3 in Mandarin is indeed converted into 2 3, nothing else. (2) The to nes of Mandarin Chinese that start from low pitch levels (35, 21) tend to present significantly different VAT values from those that start from high pitch levels (55, 51), with mean VATs of the former being much longer than those of the latter. This embodi es the nonlinear contra variant relationship between VAT and F0 at vowel onsets. (3) There are deviations or individual differences: a small number of people do not follow this pattern.

摘要： 本文在汉语音高相关研究的基础上，通过呼吸带传感器所记录的呼吸节奏变化，来分析呼吸节奏与音高（基频）之间的关系。本文按照大、中、小呼吸单元（一、二、三级呼吸）来对语料进行统计分析。一般情况下一个自然段为一个大呼吸单元，自然段里的复句对应中级呼吸单元，分句或句子成分对应小呼吸单元。我们依据呼吸重置研究了基频重置的情况，总体而言：1）呼吸重置和基频重置是规律对应的；2）在三个级别的呼吸节奏中，呼吸的重置（截距）相对比较稳定；3）一级呼吸重置中的基频重置并不大于二、三级呼吸重置的基频重置；4）基频的斜率和时长成正比；5）基频的斜率和截距成反比。
