Electropalatography (EPG) has proven to be a useful clinical and research tool for measuring tongue-to-palate contact. Research has shown sensorimotor adaptation to an EPG device may be possible following a short period of speech practice. This study was developed in order to better understand how a listeners' perception of speech clarity is effected by the presence of a relatively thin artificial pseudopalate in the speakers' oral cavity. Twenty listeners rated 220 speech stimuli on a visual analog scale ranging from normal to very distorted speech clarity. The stimuli included two different American English sentences. Speech clarity ratings were looked at …
