Speech Prosody 2004
Early perceptual processing capabilities are likely to contribute to the categorization of lexical vs. grammatical words by newborns. This lexical categorization could be performed by detecting differences in the prosodic structure of these word categories. We demonstrated that this lexical categorization could be performed using many prosodic cues (duration, F0, energy and formants) automatically extracted for 10 different speakers.
