In this paper, we start from the energy point of view, use AM-FM modulation model and formant frequency, to remove the vocalic interference which vast majority of energy in the useful speech. 本文从能量角度入手,利用调频-调幅模型和共振峰特征,滤除混叠在有用语音中的含绝大部分能量的元音干扰。
Algorithm of piecewise linear predictive coding for speech formant frequency estimation 语音信号共振峰频率估计的分段线性预测算法
The formant frequency formula can be adapted to the virtual instrument system after being corrected through experiment. 用实验的方法,对改进的狭缝共振吸声结构的共振频率公式进行修正,使其适合该虚拟仪器系统。
The transformation of the formant central frequency and bandwidth is the main causation cause the Helium speech. 结论表明,语音共振峰中心频率和带宽的变化是引起氦语音现象的主要原因。
The different pitch and the different formant frequency decide the different pitch-scale. 不同的语音音调主要体现在语音的基音周期和共振峰频率的差别上。
So an algorithm based on LPC is discussed in detail at first in this paper, in which the formant central frequency and bandwidth can be controlled independently by direct operation on the poles of all poles model of vocal tract filter. 在此基础上,介绍了基于线性预测(LPC)的增强算法,使共振峰的中心频率和带宽,可以通过对声道滤波器全极点模型极点的操作进行独立调节,从而实现对氦语音的矫正。

When monosyllables are connected to two-syllable words in Chinese speech synthesis, Many parameters, such as F0. formant frequency, length and amplitude of syllable change. 汉语语音合成中,在将单音节连接成二字词时,音节的很多音段、韵律特征参数,如基频、共振峰频率、音节时长、幅度等都发生了变化。
Objective To analyze the formant frequency of vowels in the sequence therapy of patient with cleft palate. 目的了解腭裂术后患者语音矫治后元音发音的改变,明确语音矫治对腭裂患者语音改善的重要性。
Besides extracting the spectral envelope, PLPC could be used to estimate the formant frequency and detect the pitch period. 除了提取语音频谱包络,PLPC算法还可用于估计共振峰频率以及检测基音周期。
