We tested for an articulatory effect on perception by bimonthly recordings of monolingual English and Welsh children, from age 10.5 to 12 months. The infants were tested at 12.5 months on closely matching lists of nonword stimuli constructed to highlight one of two consonants of comparable input incidence (English /t/ vs. /s/; Welsh /b/ vs. /g/). Listening times were in inverse correlation with the children's relative frequency of use of the pair of consonants (p<.05), a novelty effect. The findings demonstrate an effect of motoric practice on infant speech perception. We speculate that production may support the establishment of more robust lexical and phonological representations.
