Research direction

Start by reproducing the Korean dialogue across multiple eight-second clips in ComfyUI using a stock H3 workflow, then compare the model and workflow with the separate app’s setup. The issue does not identify relevant files or tests; first establish whether the garbling also occurs outside that app. Done means the cause is identified or the behavior is reproducible with a documented model and workflow.

Description

I’m using MiniMax H3 locally on Windows through ComfyUI, with a separate app (Gemma Studio) that prepares the prompts and submits the jobs. I wrote the dialogue in Korean and labeled each line with the speaker’s name.

In the first clip, I can clearly hear the intended line: “저는 강아지 목욕도 시켜 주고 인형을 가지고 가서 놀아주기도 할 거예요.” In the next two clips, the speech sounds very fast and I can’t understand it. All three clips are eight seconds long.

Has anyone else heard this, especially when continuing a scene across multiple clips? If you’ve seen it with a stock ComfyUI H3 workflow, which model and workflow were you using? I’m trying to find out whether others see the same behavior and whether it also happens outside my app’s workflow.
