Abstract

A study showing an articulatory study of North American English productions of one typically developing child is presented. The current study uses ultrasound imaging to investigate the articulations of one typically-developing North American English-speaking monolingual child, aged 4:3. The experiment was conducted in a soundproof booth and consisted of one 45-minute session that included four short recordings, each approximately five minutes in length. The participant was seated on her mother's lap during recording and a hand-held transducer was placed gently under her chin to capture mid-sagitial views of the tongue during speech. Video recorded with a USB video camera, and UltraSpeech software was used to capture ultrasound and video images, at a rate of 30 fps. The participant accurately named all target items with the exception of 'crow,' which was identified as 'bird' and included as a syllabic token.
