利用线性预测谱估计方法分析前响元音的共振峰，通过得到共振峰F1和F2的值，与前响元音的的两个音素单独发音时的F1和F2作比较，最终做出五个前响元音与组成音素的声位图。-Use of linear prediction spectral estimation to analyze the formant of the vowel sound before, and the formants F1 and F2 values, and the vowel of the former ring when the separate pronunciation of two phonemes F1 and F2 for comparison, and ultimately to make five The front ring vowel with the sound of the constituent phonemes of the bitmap.
