The Use of Spoken Language in the Evaluation of Assistive Listening Devices

The primary objective of modern approaches to selecting a hearing aid or other assistive listening device for a person is to optimize speech intelligibility. To achieve this objective, researchers and clinicians are required to make certain assumptions about the nature of the speech signal and how speech can and should be used to evaluate hearing aid processing. This paper addresses three aspects of this issue: (1) alternative definitions of "the speech signal" as they are applied to establish amplification targets for hearing aid prescription; (2) measurement of the electroacoustic effects of hearing aid processing on speech; and (3) prediction and measurement of the intelligibility of hearing aid processed speech.
