Google Translation goes Thai…

The good news is that Google Translate can translate Thai-English and English-Thai. The bad news is that it’s not terribly good. Not shockingly bad. Not frightfully awful. Just not terribly good.

But you can make it better.

From Rikker: Notice that after you paste text to be translated, there’s a link on the bottom right of the results page inviting you to “Suggest a better translation.” This is great, because it harvests human knowledge to augment the machine translation.

You can do even more by checking out Google’s Translation Tools.

  • Add the Translate gadget to your webpage
  • Add the Google Thai button to your browser’s toolbar

There’s also:

You can even create your own mini-dictionary with Google’s Spreadsheet Translator.

And further into the future there might even be Google Translation Bots for Thai.

Other online Thai dictionaries and translators…

Thai – English Dictionary Online. – Dictionary
The cream of’s Thai dictionary has got to be the extra goodies. The one I use is the Reverse Phonemic Transcription. When I’ll find a mysterious transliterated Thai word I paste it in. Sometimes it works. Sometimes not.

Thai to English dictionary & transliteration
This is the one I use most often as it’s user-friendly. There’s also a Thai2english Dictionary Download. Just like Google Translation, you can paste whole sentences. Unlike Google Translation, you scroll over individual words to get the translation.

Apparently mine is คัตทรีน, pronounced Khat Sin. I’m not saying that my mother would agree, but Sin is marginally better than Mao.

  1. TITLE: Thai-English Dictionary พจนานุกรม ไทย-อังกฤษ (ฉบับ New Age)
    AUTHOR: (Huang Yaobao)
    PUBLISHER: Thaiways Publications Co. LTD.
    ISBN: 974-94107-5-0

    Compiled by a 75yo Chinese guy that emigrated to Thailand in 1948. This guy is a master of both languages! He’s been compiling dictionaries for the past 50 years! He is the author of “English by Example” which can be used in reverse to learn Thai.

    There are 2 editions, one for Thais and one for Farang.
    Dont’ bother with the Farang edition (over 1000 THB),the Thai edition is a bargain at 480 THB. 1000pp.
    Pronunciation is indicated with roman letters and a tone number.

    1=low, 2=falling, 3=high, 4=rising.

  2. Glad to do it! There are more online dictionaries around but I only picked those that worked without much hassle.

    And if anyone has any others, please feel free to add them here. The more, the merrier.

  3. You did a fantastic job of getting together so many resources. I had no idea there were that many for Thai. Thank you!

  4. Thanks Mike. There are decent Thai language learning resources out there (although not as many as for Western languages such as English or French). Wading through them all to cull out the best (as well as the dead links) can be time-consuming, so I’m hoping to make a useful contribution to the Thai learning community on WLT.

    And soon I’m going to need another bookcase, as after discovering them, I just HAVE to see what the books and courses look like for real!
