This part of ISO 8253 specifies basic methods for speech recognition tests for audiological applications. In order to assure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, this part of ISO 8253 describes requirements for the composition, validation and evaluation of speech test materials and the realisation of speech recognition tests. This part of ISO 8253 does not specify the contents of the speech material because of the variety of languages. Furthermore, this part of ISO 8253 describes how reference values shall be determined and which requirements for the realisation and manner of presentation shall be fulfilled. This part of ISO 8253 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, may require amended test procedures not specified in this part of ISO 8253. Specialized tests such as those used for evaluating directional hearing and dichotic hearing are not included in this part of ISO 8253.
