A quiet background hubbub is OK, but we don’t want additional voices that may cause a machine algorithm to identify words that are not in the written text. If you can hear distinct words apart from those of the text, the clip should be rejected. Typically this happens where the TV has been left on, or where there is a conversation going on nearby.
一定程度的噪音是可接受的，但我们不希望有太大的声音，这可能导致机器算法识别出书面文本中没有的词。如果您能听到明显的文字以外的词语，这个片段应该被驳回。这种情况常发生在电视开着，或者附近有谈话的地方。
