lottal: h - Sounds produced with the glottis (vocal cords) - the h sound is produced with open glottis; if the glottis is closed to stop the air momentarily, a glottal stop is produced: the sound represented by tt when a Beatle says "bottle", or the sound that starts each syllable if you say "uh-oh". (Corran, I think I learned somewhere also that in German any word starting with a vowel is understood to start with a glottal stop? Correct me if I'm wrong...)
