Neural encoding of voice pitch and formant structure at birth as revealed by frequency-following responses

Abstract Detailed neural encoding of voice pitch and formant structure plays a crucial role in speech perception, and is of key importance for an appropriate acquisition of the phonetic repertoire in infants since birth. However, the extent to what newborns are capable of extracting pitch and forman...
