Editing Breathy voice (section)

==Classification and terminology==
{{cn span|There is some confusion as to the nature of murmured phonation. The [[International Phonetic Alphabet]] (IPA) and authors such as [[Peter Ladefoged]] equate phonemically contrastive murmur with ''breathy voice'' in which the vocal folds are held with lower tension (and farther apart) than in modal voice, with a concomitant increase in airflow and slower vibration of the glottis. In that model, murmur is a point in a continuum of glottal aperture between modal voice and breath phonation (voicelessness). Others, such as Laver, Catford, Trask and the authors of the [[Voice Quality Symbols]] (VoQS), equate murmur with ''whispery voice'' in which the vocal folds or, at least, the anterior part of the vocal folds vibrates, as in modal voice, but the arytenoid cartilages are held apart to allow a large turbulent airflow between them. In that model, murmur is a compound phonation of approximately modal voice plus whisper. It is possible that the realization of murmur varies among individuals or languages.|date=March 2025}} The IPA uses the term "breathy voice", but VoQS uses the term "whispery voice". Both accept the term "murmur", popularised by Ladefoged.<ref>Trask (1996) "breathy voice", "murmur", "whispery voice", in ''A Dictionary of Phonetics and Phonology''.</ref>
