The spelling of the word "voelker" may seem confusing, but it actually follows the rules of German phonetics. In German, "oe" is a diphthong pronounced like the "ö" sound, which is similar to the "e" sound in "her." The "e" in "voelker" is pronounced separately, like the short "e" in "met." The "r" is rolled or trilled as in most German words. Therefore, the IPA phonetic transcription for "voelker" is /ˈfœlkər/.
