【摘要】：为得到更加精确的声道共鸣特性,人们越来越关心说话时声道的结构及其形状变化。该文从MRI 3-D图像数据中提取了汉语普通话7个单元音[a]、[o]、[酇]、[i]、[u]、[y]、[e]的声道边缘、中线和矢量半径数据,并沿着声道中线从唇到声门等间距截取声道的36个截面,对于每个截面,根据矢量半径的大小使同一个位置的截面形状作线性过渡,从而建立用矢量半径驱动的汉语普通话立体声道模型。计算模型的共振峰并合成语音样本,在与自然语音对比的听辨实验中,该模型取得了较好的语音合成效果。
[Abstract]:In order to obtain more accurate acoustic resonance, people pay more and more attention to the structure and shape change of the channel. In this paper, the data of channel edge, midline and vector radius of 7 unit sounds [a], [o], [Hu], [I], [u], [y], [e] of Chinese mandarin are extracted from MRI 3-D image data. At the same time, 36 sections of the vocal channel are intercepted along the midline of the channel from lip to glottis. For each section, the shape of the section at the same position is linearly transitioned according to the size of the vector radius. Thus, a stereo channel model driven by vector radius is established. The resonance peak of the model is calculated and the speech samples are synthesized. In the audiological experiment compared with the natural speech, the model achieves a good effect of speech synthesis.
