Pitch Characteristics And Durational Characteristics Of The Prosodic Word In Mandarin Chinese

This paper mainly focuses on two prosodic words located in sentences,and analyzes the pitch and duration characteristics of the two prosodic words in the focus and non-focus positions in the sentence.In the pitch part,we discuss the characteristics of different tone syllables in different positions of focus prosodic words and non-focus prosodic words in high-pitched points,subwoofed points and tonal regions.Secondly,we observe the pitch performance of focus rhythm words and non-focus prosody words in different tone combinations,and find out the causes of their differences while comparing the pitch,subwoofing point and pitch range of non-focus prosody words.In the length part,we compare and analyze the length,syllable length,vowel length of the prosodic and non-focus prosodic words,as well as the boundary of the prosodic word and the character of the inner syllable boundary of the prosodic word.While describing its acoustic performance,the causes of the difference and the influence of different factors on the duration of prosodic words are found out.In the pitch study,it is found that focus usually leads to higher pitch points of syllables;does not reduce the bass points of all syllables;and that some combinations of tones are not affected by focus.Not all the position of tone syllables in prosodic words will affect their pitch.In the length part of the study found: 1.The duration of each component of a focus rhythm word is extended,the most extended is the vowel of the first syllable,and the least is the vowel of the syllable at the end of the word.2.The position of the syllable affects the duration of the syllable and the vowel,and the focus increases the effect.3.Focus prolongs the length of the boundary,and the prolongation of the first vowel of the syllable boundary in the focus prosody is very significant.
