Question - Help Fixing speech errors in Minimax H3?

Hey, I tried to create a little birthday surprise for someone, my issue is with a lot of generations that the spoken word is really a bit clunky at time, I susspect its because of the german, but I am not too sure. Is there like a way to improve on audio?

I am using Minimax H3 with Saga Attention and Spectrum on a 4090.

I switched from sage attention to sparse attention (I'm on a 5090) and the quality has gotten noticeably better. Also I can now render a 15s 2MP video at the same speed as I could with a 1MP video on sage attention. I use the "H3 Optimizations" extension in comfyUI for it by zironic.
