"Plausibleize" is a word that may be unfamiliar to some, but it is a valid noun that means "to make plausible or believable." This noun consists of three syllables pronounced as \ˈplɔːz.ə.baɪz\ (plaw-zuh-bahyz) in IPA phonetic transcription. The "pl" at the beginning of the word is pronounced as "pl," not "p-l." The second syllable "au" is pronounced as "aw," the "si" sounds like "z" while the "ze" sounds like "zuh," and the last syllable "ize" rhymes with "eyes."
