以下是一个简单的Python代码,用于评估已合成的语音的MOS值:
```python
import parselmouth
import numpy as np
# load the audio file
sound = parselmouth.Sound("synthesized_audio.wav")
# extract pitch and intensity
pitch = sound.to_pitch()
intensity = sound.to_intensity()
# calculate jitter and shimmer
jitter = parselmouth.praat.call(pitch, "Get jitter (local)", 0, pitch.get_total_duration(), 0.0001, 50)
shimmer = parselmouth.praat.call(intensity, "Get shimmer (local)", 0, pitch.get_total_duration(), 0.0001, 50)
# calculate MOS value
mos = 4.5 - 0.1*jitter - 0.1*shimmer
print("The MOS value of the synthesized audio is:", round(mos, 2))
```
这个代码使用Parselmouth库来提取音高和强度,并使用Praat算法计算抖动(jitter)和闪烁(shimmer)。最后,根据MOS评分公式,计算出MOS值。
