Voiced Glottal Fricative

The breathy-voiced glottal transition, commonly called a voiced glottal fricative, is a type of sound used in some spoken languages which patterns like a fricative or approximant consonant phonologically, but often lacks the usual phonetic characteristics of a consonant. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɦ⟩, and the equivalent X-SAMPA symbol is h\.

In many languages, has no place or manner of articulation. For this reason, 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, so 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.
