- Learn the script in your first month. Romanization can't show you how Thai sounds; the script can, and it takes weeks, not years.
- Tones and vowel length change meaning, so train your ear from day one and find someone who corrects you.
- Grammar is the easy part: verbs don't change form and nouns don't change for plural. Spend your time on words, patterns and listening.
- Listen every day. Understanding fast, natural Thai is the slowest skill to build.
- There's no Duolingo course for Thai. Mix a teacher for speaking, daily review for words, and real Thai for listening.
The short answer
The order matters more in Thai than in most languages, because the script, tones and vowel length all depend on each other. Here's the path this guide follows. If you haven't chosen how many hours to put in yet, the calculator in how long it takes to learn Thai will show you what to expect.
Step 1: Learn the Thai script first
Most beginners want to skip the alphabet and read romanized Thai instead. It feels faster for about a week. The trouble is that every textbook, school and app romanizes Thai differently, and the official system (RTGS) leaves tones and vowel length out entirely: its own rules say "indications of vowel length and tone are not included". In Thai script, the spelling tells you the tone.
The Thai alphabet has 44 consonants (two of them, ฃ and ฅ, no longer used), about 32 vowel forms built from a smaller set of symbols, and 4 tone marks. That sounds like a lot, but a few patterns cover most of it:
- Consonants come in three classes, mid, high and low. The Royal Institute lists 9 mid, 11 high and 24 low letters. The class is what you need to know, more than the letter's name.
- Vowels sit around the consonant: before, after, above or below it. Many come in long and short pairs.
- The tone follows from the consonant class, the tone mark, and whether the syllable is "live" or "dead": live syllables end in a long vowel or in m, n, ng, w or y; dead ones end in a short vowel or in k, p or t.
Chulalongkorn University teaches the whole alphabet in a 30-hour course, and learners report reading slowly within a month. Learn the consonants class by class, then the common vowels, then the tone rules, reading real words from the first day.
Step 2: Train your ear for tones from day one
Thai has five tones, mid, low, falling, high and rising, and a different tone usually means a different word. So does a different vowel length. Tap any word below to hear it on its dictionary page.
| Word | Tone | Meaning |
|---|---|---|
| ข้าวkâao | falling | rice |
| ขาวkǎao | rising | white |
| เข้าkâo | falling, short vowel | to enter |
| เข่าkào | low | knee |
| เขาkǎo | rising (often high in speech) | he, she |
ข้าวkâao (rice) and เข้าkâo (to enter) have the same tone; only the vowel length differs. Mixing up ใกล้glâi (near) and ไกลglai (far) is a classic way to confuse a taxi driver.
You won't master tones in the first month, and that's fine. What matters is hearing them from the start and having someone who tells you when yours are off. On your own, record yourself saying a word, then compare it with the audio.
For all five tones with audio, the rules the script uses and a tone decoder, see Thai tones: how to hear, say and read all five.
Step 3: Learn useful words and patterns, and review them daily
Thai grammar is kind to beginners. Verbs don't change form: time is shown with words like จะjà (will) and แล้วlɛ́ɛo (already). Nouns don't change for plural, and there's no word for "the". That frees you to spend your time on words and set patterns. Start with these:
- Polite particles. Men end sentences with ครับkráp. Women use ค่ะkâ in statements and คะká after questions. You'll use them in almost every sentence.
- Question words such as อะไรà-rai (what), ที่ไหนtîi-nǎi (where) and เท่าไรtâo-rai (how much), which unlock most everyday exchanges.
- Survival phrases like ไม่เข้าใจmâi-kâo-jai (I don't understand) and อีกทีìik-tii (once more), so a conversation can keep going when you get lost.
- Words from your own life: your food, your street, your job. You'll remember what you use.
Learn words in short sentences rather than lists, and review them on a schedule. A review of research on spaced practice found that "spacing out repeated encounters with the material over time produces superior long-term learning" compared with cramming. In practice that means a short review every day, on a flashcard app or in a notebook, with older words coming back less often.
Step 4: Listen to real Thai every day
Teachers speak slowly and clearly. Thai people talking to each other don't. Understanding natural speech is the slowest skill to build, so it pays to start early, even before you understand much.
- Start with Thai made for learners. Comprehensible Thai is a free, listen-first course on YouTube, about 1,000 hours of teachers telling stories in simple Thai.
- Move on to Thai made for Thai people: YouTube channels, podcasts and dramas on topics you like, first with Thai subtitles, then without.
- Re-listen. One short clip played five times teaches you more than five new clips played once.
Step 5: Speak every week with someone who corrects you
Speaking is where most self-study stalls. Apps can check your vocabulary, but not whether your tone was falling or rising. You need a person: a teacher, a tutor, or a patient Thai friend who will tell you when you're wrong.
- Online tutors on Preply or italki mostly charge about US$10–30 an hour. One or two hours a week is enough to start.
- Language exchange apps such as HelloTalk and Tandem connect you with Thai speakers learning your language. They're free, but partners rarely correct tones.
- In Thailand, do one errand a week in Thai: order food, buy a SIM, ask for directions. Use ช้าๆcháa cháa (slowly) when people speak too fast.
School, tutor or self-study?
Every setup can work. They differ in cost, flexibility and how much correction you get. Many learners combine two.
| Setup | What you get | Cost | Suits |
|---|---|---|---|
| Language school | Structure, daily classes, a teacher who corrects you, and often an ED visa. | About ฿120–295 an hour in groups | People in Thailand with time on weekdays |
| Private tutor | Lessons at your pace and schedule, with correction on every sentence. | About US$10–30 an hour online; ฿500–600 in person | Busy schedules; anyone studying mainly alone |
| Self-study | Flexibility and the lowest cost, but nobody checks your tones. | Free to about US$150 for a course | Disciplined learners, alongside a tutor hour |
| Apps | Daily review and practice in spare minutes. | Free to a few dollars a month | Everyone, as the daily habit between lessons |

What a week of Thai looks like
Pick the plan that fits a normal week, not your most motivated one. A small amount every day beats a lot once a week.
- 15 minutes of review on your phone, every day
- 15 minutes of listening, every day
- Weeks 1–4: swap the listening for script practice
- One hour-long tutor lesson for speaking and tone correction
- 20 minutes of review every day
- 20 minutes of listening on most days
- One errand a week done in Thai
- 3–4 hours of class on weekdays
- An hour of homework and review after class
- Listening on the commute
- Weekends: use it, from markets to a trip outside the city
To see where each plan gets you and when, try the study-time calculator.
Mistakes that cost learners months
- Staying on romanization. It hides tones and vowel length, and you'll have to relearn words later.
- Ignoring tones because people "understand anyway". Teachers and friends adapt; strangers switch to English.
- Only using apps. They're great for review, but they can't hold a conversation with you or correct your tones.
- Only listening, or only studying. Input without speaking, or speaking without input, both stall.
- Long breaks. A month off costs more than a month; keep a few minutes of review going while you travel.
- Waiting to be ready. Your first real conversations will be short and clumsy. Have them anyway.
Review a little every day.

FAQ
What is the best way to learn Thai?
Learn the script in your first month, train your ear for tones from day one, review useful words every day, listen to real Thai daily, and speak every week with someone who corrects you. A school or a tutor for speaking plus an app for daily review works for most people.
Should I learn the Thai alphabet first?
Yes, in the first few weeks. Romanization isn't standardised, and the official system doesn't mark tones or vowel length, so it can't tell you how a word sounds. The script does. Chula teaches the whole alphabet in a 30-hour course.
How many letters are in the Thai alphabet?
44 consonants, two of which (ฃ and ฅ) are no longer used, about 32 vowel forms built from a smaller set of symbols, and 4 tone marks. Consonants fall into three classes (mid, high and low), which with the tone marks decide each syllable's tone.
How many tones does Thai have?
Five: mid, low, falling, high and rising. Changing the tone changes the word, so มา (maa, mid) means come, ม้า (máa, high) means horse and หมา (mǎa, rising) means dog.
Can I learn Thai by myself?
You can learn to read, build vocabulary and train your listening alone. Speaking and tones are harder without feedback, because nobody tells you when a tone is wrong. Most self-learners add a tutor for an hour or two a week.
Is there a Duolingo course for Thai?
Not for English speakers, as of October 2026. Duolingo teaches English to Thai speakers, but has no Thai course. Other apps, textbooks, online courses and tutors cover Thai.
What is the best app to learn Thai?
No single app teaches you to speak Thai. Use an app for what apps do best, daily spaced review of words and sentences, and pair it with listening practice and a person who corrects your speaking.
How much does a Thai tutor cost?
Online, most Thai tutors charge about US$10–30 an hour; Preply's average for native speakers is about US$18. In Thailand, private lessons cost about ฿500–600 an hour.
Is Thai grammar hard?
Thai grammar is one of the easier parts. Verbs don't change form, time is shown with words like จะ (will) and แล้ว (already), nouns don't change for plural, and there's no word for "the". The hard parts are tones, vowel length and understanding fast speech.
How long does it take to learn Thai?
The US Foreign Service Institute estimates about 44 weeks of full-time study (1,012 class hours plus self-study) to professional proficiency. Reading the script takes weeks, and everyday conversation takes roughly 300 class hours.
Should I learn Thai in Thailand or at home?
Both work. In Thailand you get schools, ED visas and daily practice, but many people get by in English for years. At home you rely on online tutors and listening practice. What matters is the hours you study and how much you use the language.
