The name "Sondja" is commonly spelled as such, with the IPA phonetic transcription being "/ˈsɑːndʒə/". The vowel sound in the first syllable is pronounced as "ah", the "n" sound is soft and nasal, and the final syllable is pronounced with a "j" sound, similar to the "y" sound in "yes". This is a somewhat unique spelling, as names like "Sonya" or "Sonia" are more common, but it still follows common English phonetic patterns.
