Google Translate Thai to English: how accurate is it?
Updated
If you have been pasting her messages into Google Translate, you have probably had both experiences: a reply that reads perfectly, and one that makes no sense at all. Both are normal. Machine translation between Thai and English is much better than it was a few years ago, and it still has some very specific blind spots. Knowing them saves a lot of confusion, and some arguments that were never really arguments.
What it gets right
Plain, complete sentences about ordinary things. "I am going to the market with my sister." "It is raining in Pattaya today." "What time do you finish work?" Messages like these usually translate cleanly in both directions, and the more your messages look like them, the better both of you will do.
Where it goes wrong, reading her Thai
No spaces. Written Thai does not put spaces between words, only between phrases. A translator has to guess where each word ends, and on a short, casual message it sometimes guesses wrong, producing a sentence that is grammatical nonsense.
Missing pronouns. Thai leaves out "I", "you", "he" and "she" whenever they are obvious from context. A translator has no context, so it invents them. "Miss, want to see" might come back as "He misses you and wants to see" when she meant "I miss you and want to see you". If a pronoun in a translated message is strange, it was probably added by the machine.
Texting words for "I" and "you". Thai women often use words in texts that mean something else in a textbook. Kao (เค้า) is used by many young women to mean "I", but a translator reads it as "he" or "they". Tua eng (ตัวเอง), literally "yourself", is how many couples say "you". So "เค้าคิดถึงตัวเอง" is "I miss you", and a translator may give you "He misses himself". If a translated reply suddenly mentions a mysterious "he", this is very often why.
Particles. The small words at the end of a Thai sentence, ka, na, ja, carry the warmth. Translators drop them, and a friendly reply comes out curt. Read a blunt translation as friendly by default.
Nicknames. Many Thai nicknames are ordinary words. Nok is bird, Fon is rain, Dao is star, Nam is water. A translator may give you "Bird is working tonight" when Nok is her friend. The Thai nicknames guide lists common ones.
Slang and numbers. 555 is laughter (five in Thai is "ha"), and the translator may leave it as a number. Internet spellings, stretched words and playful misspellings often come out as nothing at all. The Thai texting phrases guide explains the common ones.
Isan and Lao words. Many women who work in Pattaya grew up in Isan, the north-east of Thailand, where the everyday language is close to Lao. Words like bo (not), khoi (I) and doe (a friendly ending) are common in texts from home and among friends, and standard Thai translators handle them badly or not at all.
Where it goes wrong, sending your English
It picks your voice for you. Thai uses different words for "I" depending on who is speaking. Men usually say phom. A translator often picks a neutral or feminine word instead, so your messages can arrive sounding stiff, formal, or oddly like a woman is speaking. It is not a disaster, but it is one reason translated messages feel strange to read.
Idioms and jokes. "I'm over the moon" becomes a sentence about the moon. Sarcasm reads as sincere. Keep humour to things that are funny when taken literally.
Long sentences. Every "which", "although" and "but" is another chance for the structure to fold. Two short sentences translate far better than one long one.
Abbreviations. "Gonna", "tbh", "u" and "gr8" confuse it. Write the words out.
A simple test
If you are unsure what your message will say, translate it into Thai, then translate that Thai back into English. If what comes back is not what you meant, rewrite it shorter and plainer. It takes ten seconds and catches most problems before she sees them.
Do the same with her messages when something reads badly: try translating one phrase at a time, or ask her what she meant, simply. "Sorry, I did not understand. Can you say it another way?" is always better than guessing.
Voice and camera
Google Translate can also listen and read. Voice input is handy for short phrases, though it struggles with background noise and fast speech. The camera option reads written Thai on a sign, a menu or a note, and is surprisingly good at it.
Is there a better way?
Copying and pasting every message works, but it wears thin within a couple of weeks: several taps per message, both directions, and you are doing all the checking yourself.
On this site the translation happens in the middle. You write in your own language, she reads Thai on her phone, on LINE or in her own app, and her Thai reply comes back translated. If you want to check the machine's work, you can turn on her original Thai under each reply in your Account, with a line underneath spelling out how it sounds. The advice in this guide still applies, because every translator has the same blind spots: short, plain messages get read as you meant them.
The short version
Google Translate is good with plain sentences and weak with pronouns, slang, nicknames, dialect and tone. Write short, read her replies generously, and when something sounds wrong, assume the machine before you assume her.
