尽管临床医生感知处理语音产生的能力是评估和修复发音障碍的关键因素，但很少有人关注这一重要技能。这项研究探索了知觉任务的潜力，被称为提示交易，以评估具有不同临床经验的学生的知觉技能。在/r-w/对比的线索交易范式中，F2上的时间谱线索与F3上的频谱线索相平衡。结果表明，所有学生都存在交易关系。然而，与有临床经验的学生相比，没有临床经验的学生表现出对/w/和识别功能的声学线索的敏感性降低，这些功能的分离不太清楚。此外，没有实习经历的学生在功能（交易关系）之间的差异幅度明显较小：他们对/r/和/w/的语音感知比有实习经历的学生弱。初步结果表明，基于线索交易的任务可能有助于评估对发音错误/r/的声音线索的感知敏感性。
Although the ability of clinicians to perceptually process speech sound productions is a key ingredient in the evaluation and remediation of articulatory disorders, very little attention has been given to this important skill. This study explored the potential of a perceptual task, known as cue trading, to assess perceptual skill among students with varying clinical experience. A cue-trading paradigm for the /r-w/ contrast was used in which a temporal-spectral cue on F2 was balanced against a spectral cue on F3. Results indicated a trading relationship for all students. However, students without clinical experience demonstrated reduced sensitivity to the acoustic cues for /w/ and identification functions that were less clearly separated compared to students with clinical experience. Furthermore, the magnitude of the difference between functions (the trading relationship) was significantly smaller for students without practicum experience: They showed weaker phonetic percepts for /r/ and /w/ than did the students with practicum experience. Preliminary results suggest that a task based on cue trading could be useful in assessing perceptual sensitivity to the acoustic cues representative of misarticulated /r/.
