For those who are interested to understand Singlish accent, and how people speak in Singapore, this is a great video to watch.
The Singaporean girl in the video can smoothly switch between Singlish accent and "International accent". Do bear in mind that a lot of Singaporeans can only speak Singlish accent but a normal English speaker shouldn't have any issues to understand them
Btw, I always find Singlish accent very interesting and unique
Enjoy :)
