Using the Danish 'børneDAT' corpus, the current study aimed to (1) collect normative masked speech recognition data for 6-13-year-olds in conditions with and without interaural difference cues, (2) evaluate the test-retest reliability of these measurements, and (3) compare two widely used measures of binaural/spatial benefit in terms of the obtained scores. Seventy-four children and 17 young adults with normal hearing participated. Using headphone presentation, speech recognition thresholds (SRTs) were measured twice at two separate visits in four conditions. In the first two conditions, børneDAT sentences were presented in diotic stationary speech-shaped noise, with the sentences either interaurally in-phase ('N0S0') or interaurally out-of-phase ('N0S180'). In the other two conditions, børneDAT sentences were simulated to come from 0° azimuth and two running speech maskers from either 0° azimuth ('co-located') or ±90° azimuth ('spatially separated'). In relative terms, the children achieved lower SRTs in stationary noise than in competing speech, whereas the adults showed the opposite pattern. 12-13-year-old children achieved adult-like performance in all but the co-located condition. Younger children showed generally immature speech recognition abilities. Test-retest reliability was highest for the SRTs in stationary noise and lowest for the spatial benefit scores. Mean benefit was comparable for the two measures and participant groups, and the two sets of scores were not correlated with each other. Developmental effects were most pronounced in the conditions with interaural difference cues. In conclusion, reference data for the børneDAT corpus obtained under different acoustic conditions are available that can guide future research and potential clinical applications.
本研究旨在（1）在有无耳间差异线索的条件下，为 6-13 岁儿童收集规范的掩蔽语音识别数据；（2）评估这些测量的测试-重测信度；（3）比较两种广泛使用的双耳/空间优势衡量标准，以获得的分数。74 名儿童和 17 名听力正常的年轻人参加了研究。使用耳机呈现，在四个条件下，在两次单独的访问中两次测量语音识别阈值（SRT）。在前两种条件下，以同相（“N0S0”）或反相（“N0S180”）的方式在双耳呈现稳态语音噪声中的 børneDAT 句子。在另外两种条件下，将 børneDAT 句子模拟为来自 0°方位角，两个运行语音掩蔽器分别来自 0°方位角（“共定位”）或±90°方位角（“空间分离”）。相对而言，儿童在稳态噪声中的 SRT 低于竞争语音，而成年人则表现出相反的模式。12-13 岁的儿童在除共定位条件外的所有条件下都达到了成人的表现水平。年龄较小的儿童通常表现出不成熟的语音识别能力。测试-重测信度在稳态噪声中的 SRT 最高，在空间优势得分中最低。两种测量方法和参与者群体的平均优势相当，两组分数彼此之间没有相关性。在有耳间差异线索的条件下，发育效应最为明显。总之，现在可以获得不同声学条件下的 børneDAT 语料库参考数据，这些数据可以指导未来的研究和潜在的临床应用。
