许多研究对新音感知能力进行了研究，但很少有人研究新音感知能力与语音致音结构之间的相互作用。本研究考察了母语为普通话和英语的被试在四种音节类型（CCVV、CVV、VV、hums）中对泰国语低、中声调的辨别，以检验母语超音段经验和语音策略复杂性对新音辨别的相互作用。我们还测试了不熟悉的辅音簇和不熟悉的音段对起音的影响。在音节类型上，母语为普通话的参与者比母语为英语的人更能辨别音调。此外，识别能力不受音致复杂性的影响。然而，不熟悉的音节结构以非直观的方式影响母语普通话参与者的识别能力。他们在CCVV音节中辨别声调明显更好。然而，不熟悉的音段对声调辨别有负向影响。在英语中是不合法的，而在普通话中是允许的，这显著降低了辨音的准确性。对于母语为英语的参与者来说，/音调/的出现不会导致音调之间的歧视。这些结果表明，声调载体词的音致化结构与母语音致化经验相互作用，调节新声调感知能力。
Many studies have examined novel tone perception, but few have investigated the interaction between novel tone perception ability and phonotactic structure. We examined the discrimination of Thai low and mid tones by native Mandarin and native English participants across four syllable types (CCVV, CVV, VV, hums) to test the interaction between first language suprasegmental experience and phonotactic complexity on novel tone discrimination. We also tested the impact of unfamiliar consonant clusters and unfamiliar segments in the onset. Across syllable types, native Mandarin participants discriminated tones better than native English speakers. Further, discrimination ability was not impacted by phonotactic complexity. However, unfamiliar syllable structure impacted discrimination ability for native Mandarin participants in an unintuitive way. They discriminated tones significantly better in CCVV syllables. Unfamiliar segments in the onset, however, had a negative impact on tone discrimination. The presence of /ŋ/ onsets, which are illegal in English and allophonically permitted in Mandarin, significantly reduced tone discrimination accuracy. For native English participants, /ŋ/ onsets resulted in no discrimination between tones. These results suggest that the phonotactic structure of carrier words for tones interacts with L1 phonotactic experience in modulating novel tone perception ability.
