I’ll try to explain how. Sorry for my English. This word is pronounced like this ['lyu-byat]
We stress the first syllable "лю" and pronounce it clearly [lyu]. It sounds like the first syllable in "Luminary".
The second syllable "бят" is unstressed and we pronounce it faster. It sounds like [byat]
But If you pronounce "любят" very quickly like here it will be difficult to understand if it's "любят" or "любит". But you can always understand it by the sentence. In this sentence "любит" doesn't work.
