English Siri is not reading Korean notification correctly

I am living in Korea so I got lots of SMS notifications of Korean. But I prefer English as language for my iPhone so I setup English version of Siri.

But, When I got message from KakaoTalk or Discord, The siri ignore most of Korean word or saying something like 'eferr' which is not reliable.

Is it possible to install Korean language support on English version of Siri?

Thanks
