In many languages, [ɦ] has no place or manner of articulation. Thus, it has been described as a breathy-voiced
counterpart of the following vowel
from a phonetic point of view. However, its characteristics are also influenced by the preceding
vowels and whatever other sounds surround it. Therefore, it can be described as a segment whose only consistent feature is its breathy voice phonation
in such languages.
It may have real glottal constriction in a number of languages (such as Finnish
), making it a fricative.
