The word "strumiprivous" is a non-existent word and it is not found in any dictionary. However, if we were to break the word down phonetically, it may be spelled as /ˌstruːmis̃ˈpraɪvəs/. The sound "stru-" is followed by a nasal vowel "s̃", possibly similar to the "-ing" ending in "singing". The middle part "-ipi-" is a bit tricky as it is pronounced as a voiced bilabial fricative combined with a schwa sound. Lastly, "vous" is pronounced like "vus" and "s" is silent at the end.
