Three kinds of filler, treated differently
Pure hesitation (“um”, “uh”, “er”, and their stretched forms) is almost never meant, so it is ticked by default.
Hesitation phrases like “I mean” and “you know” are ticked only when the surrounding speech says they are padding.
Context-dependent words (“like”, “actually”, “basically”, “literally”) are listed but never ticked for you. Removing “like” from “it looked like a bug” produces nonsense, and no confidence score is worth that risk.
