Stiff voice

From Wikipedia, the free encyclopedia
Stiff voice

The term stiff voice describes the pronunciation of consonants or vowels with a glottal opening narrower, and the vocal folds stiffer, than 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][page needed] In Bru, for example, stiff-voiced vowels have tenseness in the glottis and pharynx without going so far as to be creaky voiced, whereas slack-voiced vowels are lax in the glottis without going so far as to be breathy voice.[2]

One language with stiff voice is Thai:[1]

phonation Thai IPA trans. Thai IPA translation

tenuis ป้า [pâː] aunt ตา [t̪āː] eye
aspirated ผ้า [pʰâː] cloth ท่า [t̪ʰâː] landing place

Javanese contrasts stiff and slack voiced bilabial, dental, retroflex, and velar stops:[1]

phonation IPA trans. IPA trans. IPA translation IPA trans. IPA trans.

slack voice [b̥aku] standard [d̥amu] blow [d̥z̥arit] (type of women's clothing) [ɖ̥isiʔ] first [ɡ̊ali] dig

Mpi (Loloish) contrasts modals and stiff voice in its vowels. This is not register: for each of the six Mpi tones, a word may have either a modal or stiff-voiced vowel. For example, low tone contrasts /sì/ 'blood' and /sì̬/ 'seven'.[1]
