Understanding Thai Transliteration & Pronunciation

When starting out with Thai, almost all learners rely on transliteration — a system that uses the Roman (Latin/English) alphabet to approximate the sounds of the spoken Thai language.

Transliteration provides an immediate, low-friction bridge: it allows you to start saying greetings, ordering food, and recognizing phrases on day one without having to learn 44 Thai consonants and 32 vowels first.

Because Romanization systems are not universally standardized across Thailand, different books, teachers, and apps use slightly different spelling conventions. On Fun to Learn Thai, our transliteration system prioritizes phonetic accuracy:

Keep this convention in mind as you study our flashcards. Whenever you see gài (chicken), remember that in some other textbooks it may appear written as kài.

Thai is a tonal language. The pitch contour used when pronouncing a syllable changes its fundamental meaning. A single syllable like "mai" can mean completely different things (new, wood, burn, not, or a question marker) depending on whether it is spoken in a low, falling, high, or rising pitch!

In transliteration systems, accent marks above vowels show the pitch contour:

These diacritics are crucial. When you learn to read Thai script, the native tone classes (High, Middle, Low consonants), vowel duration (short vs. long), and tone marks (ไม้เอก, ไม้โท, etc.) guide you with complete mathematical precision.

You will frequently see the letter h added after consonants such as p, t, and k in transliterated Thai words:

Thai possesses consonant sounds that sit right between English pairs. Two of the most common and important examples are:

Writing these as bp and dt helps English speakers avoid adding an English-style burst of air (aspiration) or heavy voicing that would cause your Thai pronunciation to drift toward plain p/t or b/d.
