Voiceless glottal fricative

• abstract: The voiceless glottal transition, commonly called a "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 ⟨⟩, and the equivalent X-SAMPA symbol is h.
