OBJECTIVE This work investigates auditory speech processing in normal listeners through measurement of brainstem responses to the synthetic vowel /a/. METHODS The vowel is presented in quiet and in continuous white noise with different signal-to-noise ratios (SNR) of +5, 0, -5, and -10 dB. RESULTS In the presence of noise, transient response waves V and(More)
OBJECTIVES This study investigated speech auditory brainstem responses (speech ABR) with variants of a synthetic vowel in quiet and in background noise. Its objectives were to study the noise robustness of the brainstem response at the fundamental frequency F0 and at the first formant F1, evaluate how the resolved/unresolved harmonics regions in speech(More)
Speech auditory brainstem responses (speech ABR) reflect activity that is phase-locked to the harmonics of the fundamental frequency (F0) up to at least the first formant (F1). Recent evidence suggests that responses at F0 in the presence of noise are more robust than responses at F1, and are also dissociated in some learning-impaired children. Peripheral(More)
