协调反应测量（CRM）语料库已获得广泛接受，作为一个研究工具，在背景竞争中的语音可懂度调查，并已被广泛用于信息掩蔽的研究。本研究的目的是建立CRM目标词识别在不同背景下的心理测量学特征，目标是能够确定何时适合或不适合使用CRM语料库的自适应阈值程序。目标词识别性能的自适应跟踪直接映射到单调的心理测量功能的基础上获得的两个谈话者，四谈话者，和咖啡馆噪声干扰。(C)2012年美国声学学会
The coordinate response measure (CRM) corpus has gained broad acceptance as a research tool for investigating speech intelligibility in background competition and has been widely used in studies of informational masking. The purpose of this study is to establish the psychometric characteristics of CRM target-word identification in various backgrounds with the goal of being able to determine when it is appropriate or not to use adaptive threshold procedures with the CRM corpus. Target-word identification performance based on adaptive tracking mapped directly onto the monotonic psychometric functions obtained for two-talker, four-talker, and cafeteria noise interferers.
