Thai Tone Calculator: Enter Words for Automatic Tone Analysis

Are Thai tone rules too complex? Can't remember consonant classifications? Unsure about a word's tone? StudyThai.ai's Tone Calculator helps you solve these problems – enter any Thai word, and it will automatically analyze consonant class, syllable type, tone mark, and calculate the correct tone.

This is an essential tool for learning Thai pronunciation, completely free!

Why Do You Need a Tone Calculator?

Tone Rules Are Complex

Thai tone calculation involves three factors:

Factor	Description	Possible Values
Consonant Class	Initial consonant is high/mid/low class	3 types
Syllable Type	Live or dead syllable	2 types
Tone Mark	Presence/absence of tone mark, which mark	5 types

Combinations: 3 × 2 × 5 = 30 possible combinations, each corresponding to different tone rules!

Manual Calculation Is Prone to Errors

To calculate a word's tone, you need to:

Determine if the initial consonant is high/mid/low class (requires memorizing classifications for 44 consonants)
Determine if it's a live or dead syllable (requires analyzing the vowel and final consonant)
Identify the presence/absence of a tone mark
Look up the tone in a rule table

Beginners find it difficult to complete these steps quickly and accurately.
