In phonetics, a glottal consonant is a [[consonant sound]] produced by restricting the airflow in the glottis, which is the space between the vocal cords. The most common glottal consonant in English is the "h" sound, as in "hat" or "happy". Glottal consonants can be used to distinguish between words in some languages, and they are also used as a feature of certain accents or dialects.
