The tennis players on the WTA and ATP tour are from all over the world, each having a unique name, and a unique way of saying it too.
To me, pronouncing their names in their native language is the correct way of saying their name. It's hard for people to say the players' name, especially since the commentators themselves say them wrong 99.9 percent of the time. I had to do quite a lot of digging around and asking native speakers from the players' countries as to how to say them, but it was worth it in the end.
I made these videos myself to help others learn the correct pronunciations. It was a lot of fun learning to say them, and I hope you enjoy it as well. Perhaps one day you can add these names into a tennis conversation. Trust me, people will be quite astonished by your speaking skills.
Enjoy and thank you!
