issue about speaker embedding

Hello, thanks for your great work.

https://github.com/svc-develop-team/so-vits-svc/blob/4078cb71a4400ecb158165aa64610269c1a654ec/models.py#L437

I am confused about why not add speaker embedding for z_p prediction. Because the z has used the speaker embedding and z_p should also include this information. May I know why ?
