Automated Lip Sync Animation

Hi, I am looking for an affordable way to improve my model's automated lip-sync.

I am really enjoying the Rhubarb plugin in Blender, keep using it for my YouTube channel anchor

and wrote a blog about it:

But I need to improve quality. Can you help me? Is there is a solution?
I need the best possible set up for him in Blender or any other affordable way so I could use it further for anchoring my channel.
Regards,
Max
