Issue with training at 8000Hz

[athenasaurav]

Hello Everyone,

I am trying to train on 8000Hz using VITS. But the voices are not clear after 180k steps. It looks like it's mumbling.

I have my own dataset recorded at 8000Hz.

Here is the sample of original recording

Also the generated audio sound like this

Do I need to change something in training in the config? Can someone suggest what changes need to be done?
