In this paper, we discuss automatic prosodic break detection and feature analysis. The contributions of the paper are two aspects. One is that we use classifier combination method to detect Mandarin and English prosodic break using acoustic, lexical and syntactic evidence. Our proposed method achieves better performance on both the Mandarin prosodic annotation corpus Annotated Speech Corpus of Chinese Discourse and the English prosodic annotation corpus -- Boston University Radio News Corpus when compared with the baseline system and other researches＇ experimental results. The other is the feature analysis for prosodic break detection. The functions of different features, such as duration, pitch, energy, and intensity, are analyzed and compared in Mandarin and English prosodic break detection. Based on the feature analysis, we also verify some linguistic conclusions.展开更多

By revising a modular acoustic model by Tseng＇s hierarchical prosodic phrase grouping framework and examining the much varied prosodic phrase （PPh） boundary B3 within speech paragraph, we show that statistical accounts of layered contributions reveal distinct contrasts between boundary immediate duration and intensity patterns irrespective of pause duration. Contrasts of FO contour patterns were also observed in these locations. Evidence was also obtained to illustrate how PPh boundary states are specified more by higher level discourse information than by lower level prosodic word construction. These combined results suggest that contrastive neighboring prosodic states are more significant cues to PPh boundaries than boundary pause duration. The results also help explain why in fluent speech between-phrase pause durations vary greatly, and can be applied to automatic speech segmentation.展开更多
英语逗号永远用在句子的中间,从不用在旬尾.该用它而不用,必会导致意义上的混乱.例如:Mary the hairdresser is here.要是不在这句话中加上逗号,读者就搞不清Mary是什么人,也不知道怎样读这句话.假如我们用上一个逗号:Mary, the hairdre...英语逗号永远用在句子的中间,从不用在旬尾.该用它而不用,必会导致意义上的混乱.例如:Mary the hairdresser is here.要是不在这句话中加上逗号,读者就搞不清Mary是什么人,也不知道怎样读这句话.假如我们用上一个逗号:Mary, the hairdresser is here.这样一来意思就清楚了,Mary和hairdresser是两个人.某人在对Mary讲话,告诉她hairdresser已经来了.展开更多
