双语例句
- The factors concerned in his experiments include several intrinsic syllable properties, e.g. the pitch value and pitch contour contrast among the four lexicon tones, the duration and the intrinsic intensity of finals.
与其实验有关的因素包括音节的一些内在属性，比如，四种单字调在音高值和音高曲线图方面的对立，以及韵母的时长和内在强度。 - Then the speech signal is pitch adjusted according to this pitch contour, where the original signal with time varying pitch period is converted to a signal of constant pitch period.
然后根据这一轨迹对语音信号进行基音调整，将原始的、具有时变基音周期的信号转化为一个具有恒定基音周期的信号。 - A new Mandarin pitch contour estimation method MAMDF ( Modified AMDF) is proposed on the basis of the AMDF method.
在分析AMDF基音周期估计方法的基础上，提出一种新的汉语语音基音周期估计方法MAMDF（ModifiedAMDF）。 - Also the change laws of noncircular gear pitch curves contour error is obtained by using of mathematical derivation.
借助数学推导获得非圆齿轮节曲线轮廓误差的形成机理。 - A New Method Generating Pitch Contour Based on HMM and Monte-Carlo Method
基于HMM和Monte-Carlo方法的生成基频曲线的新方法 - The eigenvector extracted by this curve fitting can avoid negative effects of the error endpoints and normalize the length of the pitch contour.
使用该方法提取出的反映基频变化趋势的特征向量，在不受基频曲线两端不准确点影响的同时起到了长度归一化的作用。 - The tones are recognized by using the pitch contour information which can be expressed by fundamental frequencies.
声调可以用基音的轮廓信息进行描述。 - A pitch contour extraction algorithm-spectrum-domain prediction-time domain detection algorithm, is presented as well in this paper. This algorithm, summing up the advantages of spectrum domain algorithm and time domain algorithm, is fast and accurate.
提出了一种频域预报&时域检测的基音轮廓提取算法，该算法综合了频域法和时域法的优点，具有快速准确的特点。 - Based on meshing principle of noncircular gears, tooth location on the pitch line has been decided and curve equation of the gear contour, gear top and gear root has been deduced.
依据非圆齿轮啮合原理，确定轮齿在节曲线上的位置，并推导了轮齿的齿廓、齿顶、齿根的曲线方程。 - Different approaches of the analysis and synthesis of the speech signal lead to different approaches of the estimation of the pitch contour.
