“…In his model, Ladefoged (1971) proposed that the size of the glottis might range from voiceless (when the vocal folds are held furthest apart), through breathy voice (where the glottis is held more open), to regular (modal voicing), to creaky (produced with a constricted glottis), and lastly to glottal closure (when the vocal folds are held closest together, hence no vibration and without phonation). According to Esposito and Khan (2020), modal phonation stands out as the most common phonation type in the majority of the world's languages that distinguish between one or both of the extremes of the continuum (i.e., voiceless sounds) and one center point (i.e., voiced sounds). However, many languages make distinctions within the voiced range of this continuum (viz., breathy, lax, tense, and creaky) in addition to modal phonation (Esposito and Khan 2020).…”
