For those who wish to stay short term in Thailand and wish to learn conversational thai, i would encourage you to take up live learning, direct from thai people. With today’s internet, you can learnt thai over Skype. You can see the teacher. You will use a common thai conversation book. Two adult students can learn and speak and listen together. You will be corrected if you pronnounce wrong.
These is a great way to learn from your own desktop or even mobile. Right from Singapore from Central Thailand. Good Thai schools charge about 30,000 for one-one coaching. But I think we can get teachers for less than 50% on a twin sharing.
As part of my ongoing plan to encourage retirement in Thailand, i encourage you to start learning thai now.
I look forward to have some Singapore friends in Thailand when I retire. Especially when you have some thai language skills.
Let me know if you wish to learn thai. BTW, another way is to have a thai boyfriend or girlfriend or to go for slow thai karaoke.
