Summary, etc Topographies of speech auditory brainstem response (speech ABR), a fine electrophysiological marker of speech<br/>encoding, have never been described. Yet, they could provide useful information to assess speech ABR generators and<br/>better characterize populations of interest (e.g., musicians, dyslexics). We present here a novel methodology of topographic<br/>speech ABR recording, using a 32-channel low sampling rate (5 kHz) EEG system. Quality of speech ABRs<br/>obtained with this conventional multichannel EEG system were compared to that of signals simultaneously recorded with<br/>a high sampling rate (13.3 kHz) EEG system. Correlations between speech ABRs recorded with the two systems revealed<br/>highly similar signals, without any significant difference between their signal-to-noise ratios (SNRs). Moreover, an<br/>advanced denoising method for multichannel data (denoising source separation) significantly improved SNR and allowed<br/>topography of speech ABR to be recovered.
