This article proposes a conceptual and measurement framework for postpubertal, L2 speech learning aptitude that is centered around domain-general auditory processing (i.e., representing spectral and temporal characteristics of sounds). To this end, we examine the construct and reliability of a battery of auditory processing tests by presenting the results of an empirical study wherein 100 participants took the tests twice. The findings showed (a) that the tasks tapped into multiple dimensions of auditory processing ability (e.g., perceptual acuity, audio-motor integration); and (b) that test-retest reliability ranged from “fair” to “excellent” (ICC (2,2) = .4–.8). Last, we introduce an offline version of the tests (deposited at L2 Speech Tools for Researchers & Teachers; http://sla-speech-tools.com/), provide a brief user manual, and invite researchers to use these tests to examine the role of auditory processing in various aspects of L2 speech learning (naturalistic vs. classroom, perception- vs. production-based practice).

领域-一般听觉处理作为第二语言语音学习能力的概念和测量框架：重测信度研究

本文提出了一个以领域一般听觉处理（即表示声音的频谱和时间特征）为中心的青春期后二语语音学习能力的概念和测量框架。为此，我们通过展示一项实证研究的结果来检查一系列听觉处理测试的结构和可靠性，其中 100 名参与者参加了两次测试。调查结果表明：(a) 这些任务利用了听觉处理能力的多个维度（例如，感知敏锐度、音频-运动整合）；(b) 重测信度从“一般”到“优秀”不等（ICC(2,2)= .4–.8)。最后，我们介绍一个离线版本的测试（存放于面向研究人员和教师的 L2 语音工具;http://sla-speech-tools.com/), 提供一份简短的用户手册，并邀请研究人员使用这些测试来检查听觉处理在二语语音学习的各个方面的作用（自然主义与课堂、感知与基于生产的实践）。
