The voiceless epiglottal or pharyngeal trill, or voiceless epiglottal fricative,[1] is a type of consonantal sound, used in some spoken languages.

The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʜ⟩, a small capital version of the Latin letter h, and the equivalent X-SAMPA symbol is H\.

The glyph is homoglyphic with the lowercase Cyrillic letter En (н).

Features of the voiceless epiglottal trill/fricative: Symbols to the right in a cell are voiced, to the left are voiceless.
