glass · grass How to hear the difference

What's different

Unlike p or k, g is voiced, so the L or R after it isn't whispered: the voice is already on, and you can hear the tongue move. In glass, the tongue tip touches the ridge behind the top teeth and lets go, and the vowel starts bright. In grass, the tongue touches nothing and the lips round, so the vowel starts darker, almost with a quick w.

The vowel itself is the same in both words, though it changes with the accent: American voices say the a of cat, most others the longer a of father. Either way it can't help you, so compare only the moment after the g, and switch to Slow, where the l and r are stretched.
