Gilbertha is not a commonly known word, but it is likely pronounced as /ɡɪl'bɜrθə/ (gil-ber-tha) based on its spelling. The IPA transcription of this word includes a hard "g" followed by "i," which gives it the "gil" sound, and the "er" in the middle makes a schwa sound, giving it the "ber" sound. The "th" in the end is pronounced as "thuh," creating the "tha" sound. Unlike other common names, Gilbertha does not have a standard spelling in different languages.
