The classic approaches for fundamental frequencies smoothing , such as linear smoothing , median smoothing and linear interpolation , can not work well in the case of that fundamental frequency is not detected correctly and several continulus frames 傳統(tǒng)基音的平滑方法:線性平滑、中值平滑和一般的線性插值方法都不能很好地處理連續(xù)的基音頻率有隨機(jī)錯(cuò)誤點(diǎn)的情況。
