双语例句
- A speech sound made with the vocal tract open.
声道敞开发出的语音。 - The FSVQ-CEC scheme is applied to an analysis-synthesis adaptive predictive speech encoding system so as to exploit the redundancy between vocal tract codevectors and excitational codevectors.
将该方案实际应用于分析合成自适应预测语音编码系统，它有效地利用了声道参数码矢和激励参数码矢之间的冗余信息。 - However, because of the differences between normal and whispered speech in source and vocal tract transfer function, it is difficult to reconstruct whispers to normal speech with the ordinary synthesis method.
由于耳语发音和正常音在激励源和声道传递函数上存在差异，所以一般的语音合成方法不再适用。 - The phoneme at the end of syllable is always voiced speech in Chinese, while voiced speech can be regarded as an output for quasi-periodic sequence of pulses acting on vocal tract.
汉语的音节末尾的音素基本都是浊音。在声学处理上浊音可以理解为准周期的脉冲串对声道激励所产生的输出。 - The pitch period shows the periodicity of lung-airflow in the process of phonation. And the spectral envelope of speech reflects on the resonance-filter property of the vocal tract model, which carries the semantic and personalized information of human.
基音周期体现了发声过程肺部气流的周期性，而语音频谱包络是人的声道共振滤波特性在频域中的表现。 - After studying the differences between speech and cough, we found the LPCC which is based on the vocal tract models is not appreciating for the cough classification. So we use the MFCC as the character parameters.
本文经过对咳嗽和语音的特点分析，发现基于声道模型的LPCC并不适合用于咳嗽分类，因此采用基于听觉特性的MFCC特征参数。 - Based on analysis to the basic model of speech production and voice transformation, vocal tract parameters and statistics of speech signals are extracted. Sensitive features are selected as classifying features by support vector machine recursive feature elimination method.
该算法提取语音信号的声道参数以及相关的信号统计量，并通过支持向量机递归特征消除法，选择对语音变换比较敏感的特征进行语音变换检测。
