Abstract

Pitch shifting finds applications in voice morphing and other speech related applications. We have used complex wavelet transform to obtain and manipulate pitch of the signal. The novelty of our model is extraction of wavelet 'pitch-scale' values, which correspond to average pitch value of signal's voiced frame. The phase matrix corresponding to this scale is altered keeping modulus unchanged. The pitch has been measured using autocorrelation in wavelet domain, both for unaltered frame and for modified frame. The results obtained indeed display altering of pitch as desired
基于复连续小波变换的语音基音变换
音高变换在语音变形和其他语音相关应用中得到应用。我们使用复小波变换来获取和处理信号的基音。该模型的新颖之处在于提取小波“音高尺度”值,该值对应于信号的浊音帧的平均音高值。在保持模量不变的情况下,改变与该尺度相对应的相矩阵。利用小波域的自相关测量了不变帧和修改帧的基音。所得到的结果确实显示了所期望的音调变化
