Contributions of pitch and spectral information to cortical vowel categorization

The perception of vowels such as [a] or [i] is based on their spectral properties, i.e. resonance frequencies (formants), and on fundamental frequency (f0). Yet, it is unclear whether early neural indices of vowel processing are predominantly driven by f0 or by formant frequencies. null A candidate neural index of early acoustic processing is the N1, a negative evoked potential of the human electroencephalogram (EEG), peaking between 80 and...
