Abstract

Neural responses in the auditory brainstem and midbrain are traditionally obtained with repetitions of basic stimuli such as clicks and tones. However, two different methods to measure subcortical responses to ongoing speech with non-invasive electroencephalography (EEG) have recently been published: one based on regularised linear regression (Maddox and Lee, 2018), and the other based on cross-correlation (Etard et al., 2009; Forte et al., 2017). Here, we compare these two methods using the same EEG data set. For both measures, we found prominent peaks in the response functions at latencies consistent with wave V of the auditory brainstem response (ABR; mean latency: 8.19 and 5.97 ms, respectively). The peak response latencies in individual participants were correlated between the regression approach and conventional click-evoked auditory brainstem responses (clickABRs), suggesting a common underlying neural source. However, similar correlations were not found between the two speech-based methods, nor between the correlation approach and click-ABRs. This could arise from either differences in the methodologies or from variability in the measures.
