People learn Thai for a handful of reasons: a trip to Bangkok or the islands, a move to Chiang Mai, a Thai partner and their family, or the itch to finally read the signs and menus. What counts as “best” depends on which of those is you.
The good news is that Thai grammar is simple, with no verb conjugations, no tenses, and no plurals. The real work is in the five tones and the script. I went through the Thai courses on Class Central and picked 10 for this Best Courses Guide, free and paid, with a pick for each kind of learner.
If you mostly want to talk, you can skip the alphabet for now and be conversational in weeks. If you want to read, or you’re staying in Thailand a while, learning the script early pays off, because Thai spelling tells you the tone of every syllable.
Which Thai Course Is Right for You?
In Thai, the tones aren’t a detail you can fix later
Skip them early, or lean on romanization that hides them, and you’ll build up a pile of words that Thai people can’t understand. The same syllable in another tone is a different word: “near” and “far” are a tone apart. Say it wrong and they won’t misunderstand you, they just won’t understand you. The courses I kept drill all five tones early, with a native voice to copy. Our start-here pick, Speak Thai from Day One, is the clearest example: its first lessons cover pronunciation and the tones before you build a sentence.
How We Chose
With that in mind, here’s what I looked for in every course here.
- Native-speaker audio you can copy, so the tones actually stick
- Starts with real, usable Thai like greetings, ordering, and directions, not grammar drills
- Says clearly whether you’ll stay on romanized Thai or learn the script
- Uses one consistent romanization instead of switching spellings on you
- Short enough that you actually reach the end
To rank them, I leaned on learner reviews here on Class Central, ratings on the platforms that host each course, and what people say on Reddit. Class Central has tracked online courses since 2011, and our small team has completed 400+ of them. Learn to Read Thai, Taught by an American Guy earned its spot as the highest-rated course in the guide, and it commits fully to one job: making the alphabet finally click. Not sure where to start? Open Speak Thai from Day One, learn to say hello and count, and add the script when you’re ready.
Best Beginner Thai Course for Speaking (Udemy)
Speak Thai from Day One is our start-here pick, and the one to open if you want to be talking rather than studying. It’s built for people who know zero Thai, and it puts the hard stuff first: how to pronounce every sound correctly, and how to hear and produce the tones so Thai people actually understand you.
From there you move into simple sentences, questions, counting, and everyday greetings, with just enough of the script explained so you understand how Thai words are built. At three hours it’s short, well-paced, and cheap, and its 4.63 rating across more than 800 learners is the strongest of any pure speaking course here.
Once you can hold a basic conversation and want to start reading the world around you, our top script pick Learn to Read Thai is the natural next step.

Best Thai Course for Reading the Script (Udemy)
Learn to Read Thai, Taught by an American Guy is the highest-rated course in this guide, at 4.87 across more than 650 learners, and it earns it. The whole premise is that a fellow English speaker who learned to read Thai can explain the confusing parts far more clearly than a native teacher who never had to figure them out.
Over about seven and a half hours you work from single consonants and vowels up to full sentences, including the tone rules that make Thai reading feel like a code at first. The instructor’s claim is that once you finish, you can sound out most written Thai, and the reviews back it up. Reading also quietly fixes your speaking, since Thai spelling encodes the tone that romanization leaves out.

Best All-in-One Thai Course (Udemy)
Learn Thai for Beginners: The Ultimate 105-Lesson Course is the pick if you’d rather have one structured path than stitch together free videos yourself. Across 105 short lessons it bundles the four things a beginner needs: an intro to the language, the alphabet, a full pronunciation guide that drills the tones, and the “Thai in Three Minutes” phrase series, plus listening practice to tie it together.
It’s produced by ThaiPod101, and it’s essentially the paid, organized version of their free Absolute Beginner Thai playlists, pulled into a single start-to-finish course. At 4.29 across more than 1,100 learners, it’s the most-reviewed Thai course in the guide. The tradeoff is breadth over depth: it introduces the script rather than drilling it, so pair it with a dedicated reading course if literacy is your goal.

| Duration | 6 hours 45 minutes |

Best Thai Reading and Writing Course (Udemy)
Master Reading and Writing Thai is the pick if you want full literacy, not just enough to sound out a menu. Taught by a native Thai speaker, it works methodically through the consonant classes, short and long vowels, blending, final consonants, the tone rules, consonant clusters, and the special symbols most courses skip.
At nearly 17 hours it’s the most thorough option here, and it comes with a downloadable ebook, flashcards, and practice games so you’re not just watching. Its 4.79 rating across 329 learners reflects how carefully it’s built. If that’s more than you want right now, Learn to Read Thai gets you reading most Thai in roughly half the time.

Best Short Thai Speaking Course (Udemy)
Thai Language: Learn to Speak Thai With Confidence is a quick, topic-by-topic speaking course for people who want practical phrases and nothing extra. In under two hours it walks through greetings and introductions, counting, dates and time, colors, weather, directions, food, travel, shopping, and health, so you leave with a usable kit for everyday situations.
It’s the shortest paid pick here, and its 4.69 rating is strong, though from a smaller pool of 178 learners. For a little more depth at a slightly lower price, our start-here Speak Thai from Day One covers similar ground and spends more time on tones and pronunciation.
| Provider | Udemy |
| Duration | 1 hour 53 minutes |
| Level | Beginner |
| Rating | 4.69 / 5.0 on Udemy (178 ratings) |
| Cost | Paid ($44) |
| Certificate | Yes (certificate of completion) |
Best Audio-Only Thai Course (Pimsleur)
Pimsleur Thai is the pick if you learn best by ear, in the car, on a walk, or anywhere you can’t look at a screen. The method is famous for a reason: short daily audio lessons that keep prompting you to recall and say things just before you’d forget them, which builds real spoken recall rather than passive recognition. For a tonal language that is an advantage in itself, since you pick up the tones by copying a native speaker instead of reading them off a page.
The Thai course runs about 16 hours and focuses on speaking and listening in Standard (Central) Thai, with some reading introduced along the way. It’s app-based and paid, either through a subscription or a one-off course purchase, and the apps rate 4.7 on the App Store and 4.3 on Google Play. If you’d rather not pay, Absolute Beginner Thai on YouTube builds spoken Thai for free, just without Pimsleur’s structured recall system.
| Provider | Pimsleur |
| Format | Audio course (app, self-paced) |

| Level | Beginner |
| Rating | 4.7 App Store / 4.3 Google Play (app) |

Best Free University Thai Course (University of Malaya)
Let’s Learn Thai Language is the best free, university-built way to get your first spoken Thai, taught by a native speaker from the University of Malaya. Over two short weeks it focuses on the basics you’ll use immediately: how to pronounce Thai like a local, the difference between formal and informal greetings, and enough conversation to introduce yourself.
It’s aimed squarely at complete beginners and travelers, and more than 5,000 people have taken it. The course is free to audit; a certificate is a paid FutureLearn upgrade, so treat this as a confidence-builder rather than a credential. When you finish, Chulalongkorn’s free Survival Thai is a natural next step for more everyday situations.

Best Free Survival Thai Course (Chulalongkorn University)
Survival Thai is a free, structured course from Chulalongkorn University, Thailand’s most prestigious school, aimed at getting you through real situations. It opens with the Thai sound system, tones and all, then moves through introducing yourself, ordering food, telling the time, making appointments, asking directions, and handling everyday needs like weather, colors, and health.
It’s genuinely free, self-paced, and focused on listening and speaking, which makes it a strong companion to the speaking picks above. There’s no certificate, and it hasn’t gathered ratings yet, so lean on it for the teaching rather than a credential. For more everyday phrases to drill alongside it, ThaiPod101’s free Absolute Beginner Thai playlists pair well.

Best Free Thai Video Lessons (ThaiPod101)
Absolute Beginner Thai for Every Day is the free video library to dip into whenever you have a spare ten minutes. It’s a large ThaiPod101 playlist, roughly nine hours in total, covering must-know phrases, verbs, adjectives, travel and restaurant vocabulary, and how to survive common situations, all with native-speaker audio.
Because it’s a set of topic videos rather than a linear course, it’s better as a supplement than a sole path: watch what’s relevant to you and let it build your vocabulary over time. If you want the same ThaiPod101 teaching in a structured, start-to-finish format, their paid Learn Thai for Beginners: 105-Lesson Course pulls it into one path.

Best Free Intro to the Thai Script (ThaiPod101)

In about 30 minutes, this short ThaiPod101 series introduces a batch of consonants and vowels, shows the correct stroke order, and gives you a first taste of the tone rules that reading depends on.
It won’t make you literate on its own, but it’s the perfect thirty-minute test before you commit to a longer course. If it clicks and you want to actually read Thai, our top script pick Learn to Read Thai takes you the rest of the way.
