I can't hear the part "they haven't been touched". It sounds like "they haven't touched". How is it pronounced?
While the speaker here does pronounce "been" properly, she does not pronounce a hard "t" when she says "haven't", and she says "been" quietly in a low voice. That is why this part is difficult to understand. In most cases, native English speakers would pronounce "haven't been" more clearly than she does.
