Important Note #1: Going from Help to the Sections When you first download and run the app, it starts in our Help screen. To get from the Help screen to the main dictionary sections, you will need to use your Android device's Menu button then touch "Section." All devices have a Menu button. If you have any trouble finding yours, see this helpful FAQ.

Important Note #2: Works Offline Our dictionary works offline, letting you look up words and play sounds without being connected to the internet. Our app uses Google Play Licensing, which does require your device to be on the internet for a few seconds every 15+ days. For more info, see this FAQ item.

Important Note #3: LastPass/Accessiblity and Android 6.0 Marshmallow: Our app does work with Android 6 Marshmallow, but if you use both Android 6 and a third-party "Accessibility" tool like LastPass, there is a conflict and a workaround for that conflict. See this FAQ for more info.

Guarantee: Forget about Google's absurd 15 minute return window: if you are not satisfied, we will give you a full refund. Buy confidently with our risk-free Money-Back Guarantee.

NEWS FLASH: We are currently working on a massive 2.0 upgrade to the Android dictionary app that has been more than two years in the making. The free dictionary upgrade will include all the features, categories, and vocabulary of our new Thai Phrasebook app. That means you will get full-text search, thousands of complete, ready-to-use customizable phrases divided into 250+ practical categories like "Hotel," "Ordering Food," "Renting a Place," and "Price Haggling," and a Favorites feature that lets you save and organize words and phrases you are learning. Plus the 2.0 upgrade will include thousands of new Thai words suggested by dictionary users over the past two years. In this 2.0 dictionary release we also hope to finally free ourselves from Google Play Licensing, which is unreliable and inconvenient for a small percent of customers and also a support burden for us. This release will also address many device-specific Thai text drawing problems because we will no longer rely on Google's flaky and ever-changing support for Thai. We expect to release the 2.0 dictionary in early 2016.

Check out a sneak preview of our major 2.0 dictionary release!

Learn Real-World Thai Script

You've probably noticed that the Thai letters appearing on signs and menus in Thailand often look nothing like what you learned in textbooks. A unique new feature of our dictionary is that you can tap on any Thai word and see that word written in a set of real-world fonts that you are likely to see on signs, menus, documents, and even in Thai handwriting. It's an indispensable feature for getting around the country:

Pronunciation Guides

Every single Thai word is accompanied by an easy-to-read, English-like Thai Sound pronunciation guide (also known as "Transliteration" or "Phonetics"), so you can learn to speak and recognize Thai words immediately, without needing to learn Thai script. Our pronunciation guides give you the tones and everything else you need to understand and to be understood.

We even let you choose which pronunciation guide system you want to use from a list of 12 popular systems.

With a single touch in our app settings screen, all pronunciation guides throughout the app transform into your chosen system, and you can even look up Thai words by sound using your chosen system.

We Go Three Ways

This dictionary goes three ways!

Three-Way Design

Most dictionary and phrasebook apps let you look up English words, and some also let you look up Thai words using Thai script. But Paiboon's revolutionary three-way design bridges the gap for English speakers by introducing a third option where you can Search-by-Sound™: you can look up Thai words that you hear by their sound using the same easy-to-read pronunciation guide. Hear someone say "sanuk?" Type "s-a-n-u-k" to find out what it means:

Thai Sound section

Search-by-Sound™ has been a hallmark of all Paiboon dictionary and phrasebook products since Paiboon's first Thai products in 2002.

For more information on Search-by-Sound™ and why it's so useful for Thai, see this section.

Multiple Pronunciation Systems

In addition to our signature Paiboon+ pronunciation guide system, the same system used in all Thai learning materials from Paiboon Publishing, this software lets you choose from 11 other pronunciation guide systems:

Pronunciation Guide Systems

With a single touch in our app settings screen, all pronunciation guides transform into your chosen system, and you can even look up Thai words by sound using your chosen system.

Introduction to Thai

  • Speaking and Listening: Consonant Sounds, Vowel Sounds, Tones, Practice Similar Sounds, Stress, Parts of Speech, Classifiers, Word Register.

You can download our free, limited trial version to get a more detailed taste of what is covered in our comprehensive introduction.

Designed for English Speakers

Unlike typical dictionaries and phrasebooks based on free, often low-quality data meant for Thai natives, our superb Paiboon Publishing dictionary entries are hand-crafted by a team of Thai- and English-native editors with your needs in mind.

Entries are richly annotated for native English speakers so you know the exact meaning of each Thai word and phrase you use (for example, the entry for "glass" clarifies "drinking glass" vs "pane of glass," which translate differently in Thai) including slang and formal variants.

Designed for English Speakers

No more Google Translate gibberish!


Classifiers are a critical part of Thai grammar, needed for even basic usage. Our dictionary provides crucial classifiers for more than 15,000 noun entries—a first in the industry. Our language introduction tells you how and when to use them.

Convenient Navigation

As you are reading any dictionary entry, you can tap on any Thai or English word in that entry to search for that word. This can be a great way to explore different shades of meaning and learn new, related words.

Also, you can tap on any part of speech or other symbol to go directly to the relevant section of our language guide to learn more.

As you look up words, help pages, or use the other special features of our app, you can always touch the back button to get back where you were, just like a web browser.

Convenient Navigation

Customize Keyboards

When typing English or Thai Sound pronunciation with our dictionary, you can choose either your standard system keyboard (or any other third-party keyboard that is available to other apps on your device) or you can choose the built-in specialized, custom Paiboon keyboard, which is exclusive to our app. The Paiboon Keyboard features large, readable key labels and only presents the keys you need for searching in the dictionary.

Our Paiboon Thai Script keyboard's large, clear labels are a dream come true:

Thai Script keyboard

The Paiboon keyboard frees you from typical Thai keyboards that have tiny labels that are nearly impossible for non-Thais to read, and include several obsolete "decoy" letters not used for any word in modern Thai (especially ฃ ฅ ๅ) that look almost exactly like common letters (ข ช ซ ค ด ต า) and often lead to failed searches (for more see this FAQ item).

Our app even supports external Bluetooth keyboards.

Customize Layout

In addition to making the text as big as you want and choosing your own keyboard, you can also choose from multiple different English and Thai fonts and configure other aspects of definition layout in our Settings screen.

For those who prefer to fit the most information possible on-screen, we even offer an alternate compact layout. Here is an example with the compact layout and customized fonts:

Search-by-Sound™ is what puts Paiboon Publishing's dictionaries and phrasebooks so far ahead of the competition, and now this indispensable capability is available on your device.

The Problem

As you may know, Thai has its own alphabet which is nothing like English and takes a long time to learn. And even if you know the Thai alphabet, there are multiple ways of writing the same sound. For example, there are 4 letters that sound like an "s," 5 letters that sound like a "k," and 6 letters that sound like a "t"! So, looking up a Thai word that you hear is difficult even for a seasoned scholar.

The Solution: Search-by-Sound™

What if you could simply look up what you hear? Search-by-Sound™, a hallmark of all Paiboon dictionaries and phrasebooks since Paiboon's first Thai product in 2002, lets you do just this.

It all starts with pronunciation guide systems. Paiboon Publishing has developed an easy-to-use pronunciation guide system called "Paiboon+," which spells out Thai words using English-like letters. With Paiboon+, there is just one simple way to write each sound. There are other pronunciation guide systems too, and if you're already familiar with another system, our app lets you choose from amongst 12 different systems in use today.

Every Thai word in our dictionary is written with the Thai alphabet and also with your chosen pronunciation guide systems. But Search-by-Sound™ takes that one step further: you can look up a Thai word by its pronunciation guide.

For example, if you hear someone say "sanuk," you just type "s-a-n-u-k":


The app provides you with the exact pronunciation, the word written using Thai script, the definition, and you can even touch to hear a high quality sound recording of a native Thai speaking that word.

Conquer Those Terrible Tones

Thai is a tonal language: in addition to having particular vowels and consonants, each syllable has a particular pitch contour (middle, low, falling, high, or rising). When you listen, you must recognize those tones to fully understand. When you speak, you must use the tones to be understood. Needless to say, this is often hard for native English speakers.

Search-by-Sound™ makes this much easier by allowing you to search for a word without needing to know its tones. You can then look at all the possibilities and choose the correct meaning from context.

Throughout our app, Thai words are always shown in both Thai script and using a pronunciation guide. So, if you look up an English word, you can rely on the pronunciation guide to help you pronounce the word correctly and be understood.
