Electrophysiological analysis of brainstem encoding of speech: Speech Auditory Brainstem Response.
n this PhD work, we have setup an speech-ABR stimulation and recording chain. Firstly, we have verified the validity and authenticity of speech-ABR recording (Akhoun et al., 2008b). Then, we have studied the link between the acoustic features of speech stimuli and the speech-ABR signal. We have found that speech-ABR reflects the stimulus temporal envelope (Akhoun et al., 2008a), but it appeared that this fact was rather due to the presence of high-frequency harmonics rather than the temporal envelope itself (Akhoun et al., 2010)
