【摘要】：呼吸对人类生存和言语交流起着至关重要的作用,目前,言语生理的研究已成为语音学研究的一个重要方面。本文以藏语拉萨话新闻为研究对象,用呼吸带、麦克风和喉头仪采集男女各20篇新闻朗读的语音信号和胸腹呼吸信号,通过MATLAB编写“言语呼吸韵律分析平台”并进行参数设置、标注和提取,最后进行数据的统计和分析。主要用到的语音韵律参数有：静音段时长,语音段时长：句子、韵律短语、韵律词和音节时长；呼吸参数有：呼吸周期时长,吸气相时长,吸气相幅度,吸气相斜率,呼气相时长,呼气相幅度,呼气相斜率。研究内容主要分为新闻朗读的韵律特征、新闻朗读的呼吸特征以及新闻朗读的呼吸和韵律关系三大部分。对1007个呼吸周期和13940个韵律单元的各项参数进行研究,得到以下结论： (1)男声韵律单元时长集中且稳定性好,男声朗读中韵律处理比女声稍显细腻。韵律短语和韵律词包含音节的跨度比汉语的研究结果略大,韵律等级越高,包含韵律数量越不稳定。 (2)根据胸呼吸参数将呼吸类型分为十六种,并进行各个参数分析；根据胸呼吸周期的标注,将腹呼吸也标出1007个周期,并根据腹呼吸的走势将其分为四种趋势,最终将胸腹呼吸关系归纳为49种,并对胸腹呼吸关系从参数上进行统计分析。 (3)呼吸周期包含的韵律单元级别越高,数据变化越少,也越稳定。由于新闻和藏语本身的特点,有些情况下会造成呼吸周期包含的音节数较多,在不同位置的呼吸周期中,包含的韵律单元的语音韵律和呼吸参数都会有不同的特点。
[Abstract]:Respiration plays an important role in human survival and speech communication. At present, the study of speech physiology has become an important aspect of phonetics. This paper takes Tibetan Lhasa dialect news as the research object, collects the speech signals and chest and abdominal respiratory signals of 20 articles of news reading by men and women with respiratory tape, microphone and laryngometer, and compiles "speech breath prosody analysis platform" through MATLAB and sets the parameters. Label and extract, and finally carry on the statistics and analysis of the data. The main phonetic prosodic parameters are: the duration of the mute segment, the duration of the speech segment: sentences, prosodic phrases, prosodic words and syllable duration; The respiratory parameters are: duration of respiratory cycle, amplitude of inspiratory phase, slope of inspiratory phase, duration of expiratory phase, amplitude of expiratory phase, slope of expiratory phase. The research contents are divided into three parts: prosodic characteristics of news reading, breathing characteristics of news reading and relationship between breathing and prosody of news reading. The parameters of 1007 breathing cycles and 13940 prosodic units were studied. The conclusions are as follows: (1) the prosody unit of male voice is concentrated and stable, and the prosodic processing of male voice is slightly more delicate than that of female voice. The span of syllable in prosodic phrases and prosodic words is slightly larger than that in Chinese, and the higher the prosodic grade is, the more unstable the quantity of included prosody is. (2) 16 types of respiration were classified according to the parameters of chest respiration, and each parameter was analyzed. According to the label of chest breathing cycle, 1007 cycles of abdominal and abdominal respiration were marked, and they were divided into four trends according to the trend of abdominal respiration. Finally, the relationship between chest and abdomen was classified into 49 kinds, and the relationship between chest and abdomen was statistically analyzed in terms of parameters. (3) the higher the level of prosodic unit included in respiratory cycle, the less change and stability of the data. Because of the characteristics of news and Tibetan language, in some cases the breathing cycle contains more syllable, and in different positions, the phonetic prosody and the breathing parameters of the included prosodic unit will have different characteristics.
