Phonation threshold pressure values reported in the literature have largely been determined with use of one of three consonant-vowel sequences, /pi/, /pae/, and /pa/; however, it is not currently known if vowel choice influences phonation threshold pressure values. Based on the evidence that describes velopharyngeal closure variations between vowels, this ...
