Envelope and periodicity cues may provide redundant, additive, or synergistic benefits to speech recognition. The contributions of these cues may change under different listening conditions and may differ for younger and older adults. To address these questions, younger and older adults with normal hearing listened to interrupted sentences containing different combinations of envelope and periodicity cues in quiet and with a competing talker. Envelope and periodicity cues improved speech recognition for both groups, and their benefits were additive when both cues were available. Envelope cues were particularly important for older adults and for sentences with a competing talker.
包络和周期性提示可能为语音识别提供冗余、附加或协同的益处。这些提示的贡献可能会在不同的听力条件下发生变化，并且对于年轻人和老年人可能有所不同。为了解决这些问题，具有正常听力的年轻人和老年人在安静和有竞争说话者的情况下，聆听包含不同包络和周期性提示组合的中断句子。包络和周期性提示都改善了两组人的语音识别，并且当两个提示都可用时，它们的益处是附加的。对于老年人和有竞争说话者的句子，包络提示特别重要。
