标准摘要
[中文适用范围]： 本文件规定了听力学应用语音识别测试的基本方法。 注：语音材料示例在附录A中给出。 为了保证不同测试程序（包括不同语言的语音识别测试）之间的精度和可比性的最低要求，本文件规定了语音测试材料的组成、验证和评估的要求，以及语音识别测试的实现。 由于语言的多样性，本文件没有具体说明演讲材料的内容。 此外，本文件还规定了参考值的确定、实现要求和呈现方式。 此外，所描述的语音测试的一些特征很重要，但不应被理解为必需的。 本文件规定了语音测听的程序和要求，其中记录的测试材料由听力计通过传感器呈现，例如耳机、骨振动器或用于声场测听的扬声器装置。 描述了使用噪声来掩盖非测试耳朵或作为竞争声音的方法。 某些测试对象（例如儿童）可能需要修改本文件中未指定的测试程序。 专门的测试，例如用于评估定向听力和双耳听力的测试，不属于本文件的范围。 [外文原描述]： This document specifies basic methods for speech recognition tests for audiological applications. NOTE Examples of speech materials are given in Annex A. In order to ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, this document specifies requirements for the composition, validation and evaluation of speech test materials, and the realization of speech recognition tests. This document does not specify the contents of the speech material because of the variety of languages. Furthermore, this document also specifies the determination of reference values and requirements for the realization and manner of presentation. In addition, there are features of speech tests described which are important to be specified, but which are not understood as a requirement. This document specifies procedures and requirements for speech audiometry with the recorded test material being presented by an audiometer through a transducer, e.g., an earphone, bone vibrator, or loudspeaker arrangement for sound field audiometry. Methods for using noise either for masking the non-test ear or as a competing sound are described. Some test subjects, for example children, can require modified test procedures not specified in this document. Specialized tests, such as those used for evaluating directional hearing and dichotic hearing, are outside the scope of this document.
