摘要
本研究通过对比单词和单词片段(初始 CV 音素)中初始摩擦音的评分,探讨词性对瑞典语咝声摩擦音梯度判断的影响。研究人员从有经验的听者(语言病理学家)和无经验的听者那里获得了视觉模拟量表(VAS)判断,并使用贝叶斯混合效应贝塔回归法比较了词性的影响。总体而言,与缺乏经验的听者相比,语言病理学家在听者内部和听者之间具有更高的可靠性。与缺乏经验的听者相比,SLPs 作为一个群体对摩擦音的目标评价更高,精确度也更高。所有听者都能观察到词性的影响,但影响的程度各不相同。虽然 SLP 对瑞典儿童初始无声摩擦音的评分受词性的影响较小,但我们的研究结果表明,如果不考虑可能存在的词性偏差,以前对非词汇性 CV 音素的 VAS 评分结果不能直接应用于临床。
Exploring the effect of lexicality and listener experience on gradient ratings of Swedish sibilant fricatives.
This study explores the influence of lexicality on gradient judgments of Swedish sibilant fricatives by contrasting ratings of initial fricatives in words and word fragments (initial CV-syllables). Visual-Analogue Scale (VAS) judgments were elicited from experienced listeners (speech-language pathologists; SLPs) and inexperienced listeners, and compared with respect to the effects of lexicality using Bayesian mixed-effects beta regression. Overall, SLPs had higher intra- and interrater reliability than inexperienced listeners. SLPs as a group also rated fricatives as more target-like, with higher precision, than did inexperienced listeners. An effect of lexicality was observed for all individual listeners, though the magnitude of the effect varied. Although SLP's ratings of Swedish children's initial voiceless fricatives were less influenced by lexicality, our results indicate that previous findings concerning VAS ratings of non-lexical CV-syllables cannot be directly transferred to the clinical context, without consideration of possible lexical bias.
