Abstract：
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.
摘要：
使用丹麦语\'børneDAT\'语料库，当前的研究旨在（1）在有和没有耳间差异提示的情况下，收集6-13岁儿童的规范蒙面语音识别数据，(2)评估这些测量的测试-重测可靠性，和（3）比较两种广泛使用的双耳/空间效益的措施在获得的分数。74名儿童和17名听力正常的年轻人参加了比赛。使用耳机演示,在四种情况下，在两次单独的访问中测量了两次语音识别阈值（SRT）。在前两个条件下，børneDAT句子在数字固定语音形状的噪声中呈现，与句子耳间同相（\'N0S0\'）或耳间异相（\'N0S180\'）。在其他两个条件下，børneDAT句子被模拟为来自0°方位角和来自0°方位角（\'共同定位\'）或±90°方位角（\'空间分离\'）的两个运行语音掩蔽器。相对而言,孩子们在静止噪声中的SRT比在竞争语音中的SRT低，而成年人则表现出相反的模式。12-13岁的儿童在除同一地点以外的所有情况下都取得了成人般的表现。年幼的孩子通常表现出不成熟的语音识别能力。在平稳噪声中，SRT的重测可靠性最高，而在空间效益分数方面最低。两个指标和参与者组的平均获益具有可比性，两组评分不相关。在具有耳间差异线索的条件下，发育影响最为明显。总之,在不同声学条件下获得的børneDAT语料库的参考数据可用于指导未来的研究和潜在的临床应用。
