[Bug] can not generate test sample from yourtts

[alikhabazian]

Describe the bug

I add this code

import soundfile as sf
data = model.test_run(None)

for index in data["audios"].keys():
    audio_array=data["audios"][index]
    sf.write(f"{index}.wav", audio_array, SAMPLE_RATE)

instead of model.fit() in end of file train_yourtts,py
and use pretrained model to get inference but it generate trash sounds

To Reproduce

import soundfile as sf
data = model.test_run(None)

for index in data["audios"].keys():
    audio_array=data["audios"][index]
    sf.write(f"{index}.wav", audio_array, SAMPLE_RATE)
