Multiple dimensions of language dominance, such as language proficiency and demand for language use, can be reflected in bilinguals' speech-in-speech recognition scores. This paper explores the feasibility of using a novel measure to estimate language dominance for bilinguals: relative speech-in-speech recognition thresholds (SRTs) or the within-person difference in SRTs between their two languages.
Participants were 25 Spanish/English bilingual adults ( = 30 years). SRTs for sentence recognition in a language-matched two-talker masker were measured in English and in Spanish using an adaptive, open-set task. Relative SRTs were calculated by subtracting the Spanish SRT from the English SRT. Language dominance and proficiency were assessed by established measures.
Spearman correlations were used to assess the association between measures.
Relative SRTs were correlated with dominance scores derived from both a questionnaire ( = -.80) and standardized testing ( = -.80).
We tested and validated a novel measure, relative SRTs, to predict language dominance in bilingual adults. This time-efficient method could be used by bilingual researchers interested in assessing language dominance for descriptive or experimental purposes.
Relative SRTs show promise as a valid method to assess language dominance in Spanish/English bilingual adults.
语言优势的多个维度，如语言熟练度和语言使用需求，可在双语者的语音中语音识别分数中得到体现。本文探讨了使用一种新方法来估计双语者语言优势的可行性：相对语音中语音识别阈值（SRT）或其两种语言之间SRT的个体内差异。
参与者为25名西班牙裔/英语双语成年人（平均年龄 = 30岁）。使用自适应开放集任务，在英语和西班牙语中测量在语言匹配的双说话者掩蔽器中句子识别的SRT。通过从英语SRT中减去西班牙语SRT来计算相对SRT。通过既定方法评估语言优势和熟练度。
使用斯皮尔曼相关性来评估各测量方法之间的关联。
相对SRT与来自问卷（r = -.80）和标准化测试（r = -.80）的优势分数相关。
我们测试并验证了一种新方法，即相对SRT，以预测双语成年人的语言优势。这种省时的方法可供有兴趣出于描述或实验目的评估语言优势的双语研究人员使用。
相对SRT有望成为评估西班牙裔/英语双语成年人语言优势的有效方法。
