标准范围

ISO 8253-3:2012规定了用于听力学应用的语音识别测试的基本方法。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，ISO 8253-3:2012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，ISO 8253-3:2012未规定演讲材料的内容。此外，ISO 8253-3:2012还规定了参考值的确定以及实现和呈现方式的满足要求。ISO 8253-3:2012规定了语音测听的程序和要求，记录的测试材料通过耳机的空气传导或声场测听的扬声器呈现。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ISO 8253-3:2012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ISO 8253-3:2012的范围内。

ISO 8253-3:2012 specifies basic methods for speech recognition tests for audiological applications.In order to ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, ISO 8253-3:2012 specifies requirements for the composition, validation and evaluation of speech test materials, and the realization of speech recognition tests. ISO 8253-3:2012 does not specify the contents of the speech material because of the variety of languages.Furthermore, ISO 8253-3:2012 also specifies the determination of reference values and fulfilment requirements for the realization and manner of presentation.ISO 8253-3:2012 specifies procedures and requirements for speech audiometry with the recorded test material being presented by air conduction through an earphone, or from a loudspeaker 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 amended test procedures not specified in ISO 8253-3:2012.Specialized tests such as those used for evaluating directional hearing and dichotic hearing are outside the scope of ISO 8253-3:2012.
