This page shows example videos illustrating how the tongue moves when Irish speakers produce slender (palatalized) vs. broad (velarized) consonants. Click on any example word below to see a) the ultrasound video, b) an animation based on the ultrasound videos, and c) a slowed down version of the animation.
If you read through the descriptions below, you’ll see a pattern. In the case of broad (or velarized) consonants, the tongue body needs to be relatively back (and sometimes high) in the mouth; for slender (or palatalized) consonants, the tongue body needs to be relatively forward (as well as high) in the mouth.
Most languages don’t have a broad vs. slender distinction in their consonants. (Russian is another language that does, however.)
