About ThaiLetters.com
ThaiLetters.com (อักษรไทย, “Thai letters”) is a free, browser-based flashcard trainer for the Thai writing system — all 44 consonants, the vowel signs, and the Thai numerals. It is built and maintained by Genext Information Systems, an independent software studio based in Thailand that makes small, focused web tools. This page explains who is behind the site, why it exists, and how the learning content is put together, so you can judge for yourself whether to trust it.
Why we built this
Most people who decide to learn Thai hit the same wall on day one: the script. The 44 consonants look unfamiliar, several of them sound nearly identical to an English speaker, and the consonant-class system that drives tone feels impossible to hold in your head. The usual advice is to “just memorise them,” which is slow and discouraging.
We wanted a tool that does one thing well: get a complete beginner from “these are just shapes” to confident recognition of every Thai letter, without an account, a download, a paywall, or a 40-minute video. Spaced, shuffled flashcards with an honest self-grade are one of the most effective ways to build that recognition, so that is exactly what the trainer is — nothing more, nothing less.
Who is behind the site
The site is operated by Genext Information Systems, a small independent developer based in Thailand. We build lightweight reference and learning tools, and we use the Thai language and writing system in daily life — which is what prompted this project in the first place. That day-to-day, on-the-ground familiarity is why the letter names, example words, and “sounds like” clues are chosen the way they are: to match how the letters are actually taught and used, not just how a textbook lists them.
We are software makers, not a language school, and we are upfront about that. Where the content is a simplification, we say so.
How the content is put together
Every flashcard pairs a letter with four things: its traditional name (for example ก ไก่, “gor gai”), a plain-English pronunciation clue, its consonant class where relevant, and optional spoken audio. A few principles guide how we build that:
- Traditional names first. Thai children learn each consonant by its classic name-word (the “ก ไก่ — gor gai (chicken)” pattern). We use the same standard set, because it is what every Thai speaker recognises and what teachers use.
- Pronunciation clues are approximations. The “sounds like” hints map Thai sounds onto English reference points. They are deliberately simple learning aids for absolute beginners, not a precise phonetic transcription. Thai has sounds and tones that English does not, so a clue can only get you close.
- Consonant classes are flagged (high, mid, low) because the class of the initial consonant, combined with vowel length and tone marks, decides a syllable’s tone. Getting comfortable with classes early pays off when you start reading words.
- Audio uses your device’s built-in voices. When you press “Hear it,” playback relies on the speech voices already installed on your phone or computer. A Thai-language voice gives the most accurate result; we do not host our own recordings.
We review the letter set, names, and example words against standard references and correct anything that is wrong or unclear. If you spot an error, we genuinely want to hear about it — see the contact page.
What this site is — and isn’t
ThaiLetters.com is a recognition trainer. It is a strong first step for reading Thai, and it pairs well with a proper course, a tutor, or a textbook. It is not a full Thai course, and the pronunciation clues are not a substitute for hearing the language from native speakers and a qualified teacher. For a broader overview of the writing system, a reference such as the Thai script article on Wikipedia is a reasonable next stop.
