What a confusing audio bite. :) "Lower", meaning "look angry", otherwise "lower". The first pronunciation means "to look angry"; You pronounce the "low-" the same as the sound in "loud". This is a very obscure word, so don't worry about it. What you need is the final pronunciation, meaning "less high". The "low-" is the same as in "hello"
