Wrong pronunciation of 'their'

Malaysian students will usually pronounce the pronoun 'their' as 'di ar'. When I had not delved deeper into English, I also pronounced it the same way.

However, my exposure to BBC audio files and my reference to the correct pronunciation in the Oxford and Cambridge dictionaries show that the word 'their' should be pronounced exactly like the word 'there'.

The next time you see the sentence 'It's all their own doing.', you should pronounce it as if it is written 'It's all there own doing.'

Happy studying English.
