Through a systematic literature review, this paper evaluates the clinical applicability of speech-evoked auditory brainstem responses (ABRs). The survey was done on five databases, with the following key words: speech ABR; ABR-speech; speech auditory brainstem response; auditory evoked potential to speech; speech-evoked brainstem response; complex sounds; and cABR. The search generated a list of 1288 items published between 2005 and 2015. After applying pre-established criteria of inclusion and exclusion, 21 publications remained. The collected data show that: (i) research on speech ABR has been done on diverse age groups, although teenagers and adolescents have been less studied; (ii) the speech ABR procedure has been shown to be a reliable and effective tool in evaluating the coding of speech sounds in the brainstem, and can also be applied to young children; and (iii) speech ABR has been shown to be effective in the differential diagnosis of diseases with similar features and symptoms.
