The breathy-voiced glottal transition, commonly called a voiced glottal fricative, is a type of sound used in some spoken languages which often behaves like a consonant, but sometimes behaves more like a vowel, or is indeterminate in its behavior. The symbol in the International Phonetic Alphabet that represents this sound is ɦ, and the equivalent X-SAMPA symbol is h.

Occurrence
In Sanskrit, this sound is written "ह" in Devanāgarī and transcribed as "h" and "H" in IAST.
