Why ตัดสิน sounds the way it does

Thai tone isn't random — it's produced by four things working together in each syllable: the initial consonant's class, the vowel's length, whether the syllable ends live or dead, and any tone mark. Read the row, get the tone.

Syllable	Class	Vowel	Ending	Mark	Tone
ตัด	MID	SHORT	DEAD	—	LOW
สิน	HIGH	SHORT	LIVE	—	RISING

Common questions

How do you say to decide in Thai?

To decide in Thai is ตัดสิน, pronounced dtàt-sǐn. Play the audio above to hear it spoken by a premium Thai voice — the tones are the part that spelling can't teach you.

What tones does ตัดสิน use?

ตัดสิน has 2 syllables: ตัด (dtàt) is low tone, สิน (sǐn) is rising tone.

Is the romanization dtàt-sǐn enough to pronounce it?

No — and this is the trap most learners fall into. Romanization shows you the letters, not the pitch shape your voice has to make. Thai speakers hear the tone first. Use the spelling to recognize the word, and use the audio to learn it.

The short version

ตัดสิน (dtàt-sǐn) means to decide.
It has 2 syllables, carrying the low, rising tones.
Its tone comes from the consonant class, vowel length, live/dead ending and tone mark — not from memorizing it word by word.
Reading the romanization is not the same as hearing it. Play the clip until you can say it back without looking.
