The term stiff voice describes the pronunciation of consonants with a glottal opening narrower, and the vocal cords stiffer, than what occurs in modal voice. Although there is no specific IPA diacritic for stiff voice, the voicing diacritic (a subscript wedge) may be used in conjunction with the symbol for a voiced consonant.[1]
