Automated Lip Sync Animation

Hi, I am new on Blenderartists.
I am really enjoying the Rhubarb plugin, keep using it for my YouTube channel Hero

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 so I could use it further for anchoring my channel.
Regards,
Max
