“…Instead, we interpret the outcomes of the present study in light of neurobiological models of speech perception (Ghitza, 2011;Giraud & Poeppel, 2012;Peelle & Davis, 2012) that posit a central role for endogenous theta oscillations closely following the syllabic rhythm of speech (Arnal et al, 2015;Bosker & Ghitza, 2018;Bosker & Kösem, 2017;Kösem et al, 2018). Applying these models to speech-in-noise and speech-in-speech comprehension, a range of electrophysiological studies have provided evidence that listeners' envelope-tracking response to an attended speaker is amplified compared to an ignored speaker (Dai et al, 2018;Ding & Simon, 2012;Golumbic, Cogan, et al, 2013;Lakatos et al, 2008;Mesgarani & Chang, 2012). This dynamic neural representation of the temporal structure of the attended speech stream (e.g., in a noisy environment, or with a competing speech signal) is thought to function as an amplifier and a temporal filter, aiding speech comprehension in challenging listening conditions.…”
