All are two-syllable names, and all are pronounced with the first syllable stressed (that is, spoken a bit more loudly than the second syllable).
Otherwise, they are pronounced pretty much as they are spelled.
How do you pronounce the Russian names?
1. Sonya
2. Olga
3. Anton
What about Russian pronunciation?
Is Russian pronunciation the same as English pronuncination?

These names are either written in Cyrillic script, or Roman script depending on your statement. In Russia, names such as these will be pronounced in the Russian language. In English, they will be pronounced differently.
