Main Page | See live article | Alphabetical index Fricative consonants are produced by air flowing through a narrow channel made by placing two articulating organs close together (e.g. the tip of the tongue and the upper teeth, as in the pronunciation of English initial "th" in thick, or the back of the tongue and the soft palate, as in the case of German [x], the final consonant of Bach). Turbulent airflow produces a characteristic noise called "friction". Fricatives may be voiceless or voiced (see phonation).
