【摘要】：本文主要是通过语音实验，着重分析汉语双音节词的音强和谱加重这两个声学特征，详细探究了正常格词语和轻声词的音强和谱加重，具体到声韵母的音强和谱加重，前后音节的音强和谱加重，旨在探究汉语双音节词的音强和谱加重模式，并为语音合成的建模提供一定的数据支持。通过实验我们发现，，音强方面，对于正常格词语而言，在焦点前和在焦点后的实验结果有相似之处：韵母音强均大于声母；不论是否为焦点，第二个音节的声母的音强大于第一个音节，第一个音节的韵母的音强大于第二个音节。音强增加程度方面，韵母的增幅大于声母，第二个音节大于第一个音节。轻声词的实验结果与正常格类似，其特殊表现在于焦点对音强的影响在重读音节的韵母上表现最为明显。谱加重方面，对于正常格词语的谱加重，在焦点前和在焦点后的实验结论几乎完全相同。轻声词的谱加重实验结论与正常格类似，特别之处在于焦点对谱加重的影响在重读音节的韵母上表现最突出。本实验证实了焦点对音强和谱加重都有明显的影响，并且焦点在声学上的表现为音强和谱加重的增强，因此我们认为音强和谱加重是预测焦点的有效参数。由于谱加重所受的音节位置的影响更小，我们认为其能更好地预测焦点，这对于语音合成有重要的应用价值。
[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.
