Abstract
Recent research shows that infants listen preferentially to synthesized vowels that specify an infant source and resonance properties over vowels that simulate a adult female (Masapollo et al., 2015). Infants also preferred vowels with infant resonances over vowels with adult vocal resonances when f0 values were matched (210–240 Hz) across resonance types, suggesting that infant resonance is sufficient to elicit this preference. In this study, we investigate whether infants maintain a preference for infant vocal resonances when f0 values are modulated. In experiment 1, infants listened longer to vowels with infant formants and high f0 values (400–450 Hz) than vowels with adult formants and lower f0 (315–360 Hz). In experiment 2, the same preference emerged when f0 values were reversed; infants listened longer to vowels with infant formants and lower f0 values (315–360 Hz) than to vowels with adult formants and higher f0 (400–450 Hz). These findings show that infant resonance is sufficient to elicit this p...
