Editing Whistled language (section)

==== Non-tonal whistle languages ====

In a non-tonal language, segments may be differentiated as follows:

:Vowels are replaced by a set of relative pitch ranges generally tracking the f<sub>2</sub> [[formant]] of spoken language.

:Stress is expressed by higher pitch or increased length

:Consonants are produced by pitch transitions of different lengths and height, plus the presence or absence of [[Occlusive|occlusion]]. ("Labial [[stop consonant|stops]] are replaced by [[diaphragm (anatomy)|diaphragm]] or [[glottalization|glottal]] occlusions.")
