It was hypothesized that the retrieval of prosodic and phonemic information from the acoustic signal is facilitated when prosodic information is encoded by co-occurring suprasegmental cues. To test the hypothesis, two-choice speeded classification experiments were conducted, which examined processing interaction between prosodic phrase-boundary vs stop-place information in speakers of Southern British English. Results confirmed that the degree of interaction between boundary and stop-place information diminished when the pre-boundary vowel was signaled by duration and F(0), compared to when it was signaled by either duration or F(0) alone. It is argued that the relative ease of retrieval of prosodic and phonemic information arose from advantages of prosodic cue integration.
人们假设，当韵律信息由伴随的超音段线索编码时，从声学信号中检索韵律和音位信息会更加容易。为了检验这一假设，进行了两项二选一的快速分类实验，考察了在以南方英国英语为母语的说话者中韵律短语边界与塞音位置信息之间的加工相互作用。结果证实，与仅由时长或 F0 信号化相比，当前置边界元音由时长和 F0 共同信号化时，边界和塞音位置信息之间的相互作用程度降低。有人认为，韵律和音位信息检索相对容易，这是由于韵律线索整合的优势所致。
