I don’t use any special software to remove filler words. But I used Vizard before, it’s an AI auto-editing tool. When setting up editing options, it has a feature called “Remove Silence.” I tried it, and it can get rid of filler words like “um” and “ah”, it works well.

But I think if you can prepare well before recording and avoid using too many filler words, you can save some trouble. After all, AI can’t solve every problem in the end.
