Hello @Ansen Jiang
Thanks for reaching out to us, I think you are working on installing the speech container. You must request and get approval to use a Speech container.
Have you already done that? According to the document , I don't see there is a docker with version 1.28.0 currently, could you please provide more information about how you install it? Please share any document or guidance for us to reproduce your issue.

I am happy to help further and looking forward to hearing back from you.
Regards,
Yutong
