Guests is a plural noun referring to people who are invited to visit or stay, typically for a social event or hospitality context. The word is pronounced with a short, unstressed final -s and an initial /ɡ/ consonant sound; stress falls on the single-syllable word as a whole. In everyday speech, the final sound is a voiceless alveolar sibilant, and the vowel in the middle is reduced or neutral. Overall, it identifies attendees rather than hosts.
