With the renewal of educational concepts and the intense competition, higher vocational colleges, on the basis of improving students' skills, further emphasize the use of Putonghua teaching to improve students' oral expression ability, so as to better adapt to the future employment and employment environment. This paper analyzes the importance of improving higher vocational students' oral expression ability. Aiming at the current problems and causes of students' oral expression ability, it explores effectively how to improve higher vocational students' oral expression ability from improving teaching objectives, increasing class hours, making good use of teaching resources, selecting training methods and establishing evaluation principles.展开更多

The statistical results showed that there were no significant differences in VOT between the nonstutterers and stutterers either prior to or after therapy,although the mean VOT of the stutterers was slightly greater than that of the nonstutterers.The results also indicated that both the obstruction place and the subsequent syllabic final exhibited an influence to a greater extent on VOT for the stutterers.In the spectral domain,the spectral mean of the stuttering participants before therapy was significantly different from that of the normal participants, whereas the group difference became insignificant after the therapy session.The smaller spectral mean for the stutterers might be interpreted as a more posterior occlusion in the oral cavity when producing alveolars and velars.In addition,productions of the stutterers scattered with a wider range in the space of spectral moments.Furthermore,the smaller main effect of syllabic finals on the mean spectral frequency of the burst suggested that the stutterers exhibited weaker anticipatory coarticulation than the nonstutterers.展开更多

However, the specific pitch variation of prosodic words （PWs） within sentences has not been fully understood. The dialogue material used in this study was taken from the 973 telephone conversation corpus, which includes 69 dialogues, with 79 speakers involved. The read speech material was recordings of news announcement by two announcers from radio, totally 221 sentences. Top and bottom points of pitch contour and the range of prosodic words with the sentences were studied. It was found that, for both dialogue and read speech, pitch declination exists for most sentences, with minor exceptions in the first part of longer sentences for dialogue. Compared to read speech, the pitch range of prosodic words for dialogue is smaller. For dialogue, the pitch range of the last prosodic words of the sentences are relatively larger, while there is no significant difference for pitch ranges of prosodic words in most sentences of read speech. This study will be helpful for the modeling of the pitch range and register of prosodic words in sentences in speech synthesis.展开更多

However, the feature is not very reliable in the computation. A method of conversion of the zero-crosssing rate into the main period and recognition of Putonghua initials by HMM based on the main period are proposed in this paper. The study of on-line recognition of aspirate voiceless stop consonants P, T and K, unaspirate affricative consonants ZH, Z and fricative consonant H of Chinese based on the new method has been made and we obtained 78 percent of the correct recognition rate for the initials. The implementation technique of the new method and the experiment of the initial recognition are described in the paper.展开更多

The results show: 1. Most of the diatones have several sub-classes, though the scatter of some diatone samples is small. It means that an average model is not sufficient enough to represent all samples in a sub-class. 2. The differences between the diatone model are incarnated on the differences of the highest values of Fo contours, which are correlated with the stress of the first or second syllable. 3. It is a practical and effective method in modeling the diatones in Putonghua through the techniques of polynomial curve fitting and VQ.展开更多
