Lateral bracing of the tongue during the onset phase of alveolar stops: An EPG study.

This study examined the dynamics of lateral bracing during the onset of alveolar stops /t/, /d/, /n/ produced by15 typical English-speaking adults using electropalatography. Percent tongue palate contact in the lateral regions over a 150-ms period from the preceding schwa to stop closure was measured. Rapid rising of the sides of the tongue from the back towards the front during the 50-ms period before closure was observed, with oral stops showing significantly more contact than nasal stops. This feature corresponds to well-documented formant transitions detectable from acoustic analysis. Possible explanations for increased contact for oral stops and clinical implications are discussed.
