Core Feature

See Inside Every Thai Word

Thai orthography is complex: 44 consonants, vowels that can appear anywhere, and tones encoded in the script itself. We break it down visually.

Why Thai Script Seems Impossible

No Word Boundaries

"ฉันกินข้าว" looks like one unit but contains 3 words. Where does one end and another begin?

Vowels Everywhere

Vowels can appear before, after, above, or below consonants. Sometimes all at once.

Hidden Tone Rules

The same consonant sound can be written with different letters—and each has different tone implications.

How We Break It Down

Every word in Jam Kham comes with complete syllable analysis.

สวัสดี sa-wat-dee "Hello"
Onset High
Onset Low
Vowel
Coda
ดี Final Mid
ขอบคุณ khob-khun "Thank you"
Onset High

Onset Low

Why Consonant Classes Matter

Thai has 44 consonants but only 21 sounds. The "extra" letters exist to encode tone information.

High Class 11 consonants
ข, ฉ, ถ, ผ, ส, ห
Rising tone with certain marks
Mid Class 9 consonants
ก, จ, ด, ต, บ, ป
All 5 tones possible
Low Class 24 consonants
ค, ช, ท, น, พ, ม
Different tone rules

The key insight: ส (high class) and ซ (low class) make the same "s" sound, but produce different tones in the same context. Understanding consonant classes is essential for correct pronunciation.

What You Get With Every Word

Visual Consonant Classes

Every consonant is color-coded by class. See at a glance whether it's high, mid, or low—and understand tone implications immediately.

Onset/Vowel/Coda Parsing

Thai syllables break into onset (initial consonant), vowel, and coda (final consonant). We show each part clearly so you can read systematically.

Tone Determination Display

See exactly how consonant class + tone mark + syllable type combine to produce the final tone. The mystery becomes a learnable system.

IPA Transcription

Professional phonetic notation with Chao tone numbers. Know exactly how each syllable sounds, not just how it's spelled.

Why This Matters for Learning

1

Read Systematically, Not Randomly

Instead of memorizing words as opaque shapes, you learn to parse syllables. Each new word becomes readable, not just recognizable.

2

Predict Pronunciation

Once you understand how consonant class + tone mark = actual tone, you can pronounce new words correctly even without audio.

3

Build Real Literacy

You're not just learning vocabulary—you're building the skill to read Thai independently. Signs, menus, books become accessible.
