Speech auditory brainstem responses (s-ABRs) as a new approach for the assessment of speech sounds coding

Abstract

Abstract Background The evoked auditory brainstem response (EABR) is an objective electrophysiological test used to assess the brainstem’s auditory neural activity. Speech ABR (s-ABR) testing using verbal stimuli gives more important details about how the brainstem processes speech inputs which enables the detection of auditory processing impairments that do not manifest in click-provoked ABR. The use of speech syllables in the s-ABR reveals an important brainstem function that plays a crucial part in reading development and phonologic achievement which is an assessment of speech syllables. The syllable /da/ is often utilized in s-ABR measurement being a global syllable that can be tested in many nations with effective experimental confidence. Conclusion The speech ABR is an objective, unbiased, quick test. It can be used to differentiate between many conditions such as auditory processing disorders (APD), specific language impairment (SLI), and children with academic challenges.
