标准范围

本文件规定了用于听力学应用的语音识别测试的基本方法。注？附件A中给出了语音材料的示例。为了确保不同测试程序（包括不同语言的语音识别测试）之间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、验证和评估以及语音识别测试的实现要求。由于语言的多样性，本文件未规定演讲材料的内容。此外，本文件还规定了参考值的确定，以及实现和呈现方式的要求。此外，还描述了一些语音测试的特征，这些特征很重要，需要具体说明，但并不被理解为一项要求。本文件规定了语音测听的程序和要求，所记录的测试材料由听力计通过换能器呈现，例如用于声场测听的耳机、骨振子或扬声器装置。描述了将噪声用于掩蔽非测试耳或作为竞争声音的方法。一些受试者，例如儿童，可能需要修改本文件中未规定的测试程序。专门测试，如用于评估定向听力和二分听力的测试，不在本文件的范围内。

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.
