Experimental Study On Mongolian Natural Discourse Intonation

This paper uses the speech analysis software such as Praat to quantify the natural conversational discourse of Mongolian language by using the pitch accent method proposed by Prof.Shi Feng,mainly to explore the tone of natural conversational sentences in different contexts.Trends and patterns of change.On this basis,the natural discourse accent is classified and analyzed in detail,and the effect of sentence accent on the whole sentence intonation is discussed.Based on the previous studies,the natural discourse rhythm level units are classified,and the acoustic clue parameters at the boundary,ie the pitch reset degree,the silent segment and the syllable duration before the boundary,are tested and compared to illustrate the acoustics of different prosodic hierarchical units.Characteristics,attempts to provide effective clues for the rhythm segmentation and identification of Mongolian natural discourse.Through the analysis of the pitch of natural sentences,the pitch performance of the boundary between different hierarchical relationships and semantically connected statements is examined.In order to understand the natural discourse,it attempts to provide some theoretical clues and help for the Mongolian speech synthesis work.This paper is an introduction,an introduction to the research ideas and methods,an overview of conversational structure analysis,the tonal characteristics of natural conversational sentences,the tonal characteristics of Mongolian conversational sentences,the accent acoustic representation of Mongolian natural discourse,the rhythm hierarchy of Mongolian natural discourse and The tone of the boundary,the conclusions and the remainder of the chapter are composed of six chapters and references and appendices.The research steps are as follows: firstly,the pitch analysis of the discourse of the Mongolian TV talk show is carried out,and the tonal expression in the natural discourse is described.The tone pattern of the spoken sentences in the Mongolian language is studied with reference to the predecessors’ research.Change the law.On this basis,the accent of natural discourse sentences is classified and interpreted,and the pitch performance between the acoustic representation of the Mongolian natural discourse rhythm level unit and the statements of different hierarchical relations are investigated.Studies have shown that the tone of Mongolian natural discourse in the context is highly variable and random.The main factors affecting the basic pattern of intonation are sentence stress and boundary features.The Mongolian sentence grammar accent is placed at the beginning of the sentence,and the upper arch of the pitch line is the main performance.The position of the focus accent is not traced,and the elevation of the pitch is the main performance,and the range is expanded.The bulge of the pitch line is constrained by the sentence pattern of the sentence,and the performance is different at different positions.As the boundary level increases,the associated acoustic parameters have an increasing trend.The difference between the rhythm and the rhythm small phrases is small,and the difference between the rhythm big phrases and the intonation phrases is not obvious.The difference between the rhythm small phrase and the rhythm big phrase is more obvious.Low-boundary statements are presented between statements with high hierarchical relationships,and low-level relationships are high boundaries at the boundaries.Semantic relations have no obvious influence on the boundary features of statements.
