Multifeature paradigms record fast Mismatch Negativity (MMN) ERP responses and investigate the central auditory processing. Our speech multifeature paradigm included changes in vowel, consonant, word stress, frequency and intensity. We investigated adults’ involuntary discrimination of speech sound features which are phonetically or acoustically altered. Participants watched a film without sound while pseudowords were presented through headphones. The deviants elicited MMN responses with different amplitudes. The vowel and consonant elicited the largest MMNs, while the intensity and pitch deviants the smallest. Word stress deviants elicited a double negativity. This multifeature paradigm could be utilized to record MMN, and allows to apply the MMN as assessment tool for profiling the central auditory processing of speech sounds.
