【摘要】：本文主要是通過語音實驗，著重分析漢語雙音節(jié)詞的音強和譜加重這兩個聲學特征，詳細探究了正常格詞語和輕聲詞的音強和譜加重，具體到聲韻母的音強和譜加重，前后音節(jié)的音強和譜加重，旨在探究漢語雙音節(jié)詞的音強和譜加重模式，并為語音合成的建模提供一定的數據支持。 通過實驗我們發(fā)現(xiàn)，，音強方面，對于正常格詞語而言，在焦點前和在焦點后的實驗結果有相似之處：韻母音強均大于聲母；不論是否為焦點，第二個音節(jié)的聲母的音強大于第一個音節(jié)，第一個音節(jié)的韻母的音強大于第二個音節(jié)。音強增加程度方面，韻母的增幅大于聲母，第二個音節(jié)大于第一個音節(jié)。輕聲詞的實驗結果與正常格類似，其特殊表現(xiàn)在于焦點對音強的影響在重讀音節(jié)的韻母上表現(xiàn)最為明顯。譜加重方面，對于正常格詞語的譜加重，在焦點前和在焦點后的實驗結論幾乎完全相同。輕聲詞的譜加重實驗結論與正常格類似，特別之處在于焦點對譜加重的影響在重讀音節(jié)的韻母上表現(xiàn)最突出。本實驗證實了焦點對音強和譜加重都有明顯的影響，并且焦點在聲學上的表現(xiàn)為音強和譜加重的增強，因此我們認為音強和譜加重是預測焦點的有效參數。由于譜加重所受的音節(jié)位置的影響更小，我們認為其能更好地預測焦點，這對于語音合成有重要的應用價值。
[Abstract]:This paper mainly analyzes the acoustic characteristics of Chinese disyllabic words by phonetic experiments, and probes into the sound intensity and spectral aggravation of normal words and softly spoken words in detail, including the tone intensity and spectral aggravation of the consonant. The purpose of this paper is to explore the pattern of sound intensity and spectral aggravation of Chinese disyllabic words and to provide some data support for the modeling of speech synthesis. In terms of sound intensity, we find that the results of the experiments before and after the focus are similar to those of the normal words: the vowel intensity is greater than that of the consonant, whether or not it is the focus. The consonant of the second syllable is stronger than the first syllable, and the vowel of the first syllable is stronger than the second syllable. The increase of vowel is greater than that of consonant, and the second syllable is larger than the first syllable. The experimental results of softly spoken words are similar to those of normal ones, and their special performance is that the influence of focus on sound intensity is most obvious in the vowels of accented syllables. In terms of spectral aggravation, the experimental results before and after the focus are almost identical for the normal case word spectrum aggravation. The experimental results of spectral aggravation of softly spoken words are similar to those of normal cases. The special point is that the influence of focus on spectral aggravation is most prominent in the vowels of stressed syllables. This experiment proves that focus has obvious influence on tone intensity and spectral aggravation, and the focus in acoustics is enhanced by sound intensity and spectral aggravation. Therefore, we think that tone intensity and spectral aggravation are effective parameters to predict focus. Since spectral aggravation is less affected by syllable position, we think that spectral aggravation can better predict the focus, which has important application value for speech synthesis.
