Electropalatographic data collected with and without a face mask

This study investigates the extent to which the use of a face mask conveys linguopalatal contact changes during speech production. Electropalatographic data from five Catalan speakers were collected for different consonants, i.e., the alveolar stop [n], the alveolopalatal stop [n] and the palatal approximant [j], in the sequences [iCi] and [aCe]. Results for [n] indicate more closure retraction in the mask versus nonmask condition occurring presumably when the mask is pressed forcefully against the face in front of the mouth. The use of the mask for [n] and [j] causes an increase in dorsopalatal contact, which reflects most likely a strategy of articulatory and/or perceptual compensation.
