Sound

Five tones, and the rules that decide them

Tone is not decoration in Thai, it is part of the word. มา maa is come and ม้า maa with a high tone is horse. Nothing changed but the pitch.

The five

Five example words, one for each tone. Play them in order first, then try saying each one back before you move on.

1
สามัญ saman

Mid

กา gaa crow
Level pitch in the middle of your voice
2
เอก eek

Low

ป่า bpàa forest
Low, flat pitch - slightly below normal speech
3
โท thoo

Falling

ข้าว khâo rice
Starts high and falls sharply
4
ตรี trii

High

ม้า máa horse
High pitch - sounds tense and emphatic
5
จัตวา chattawaa

Rising

ขา khǎa leg
Starts low, dips, then rises

Two things decide the tone before any mark does

The class of the first consonant, and whether the syllable is live or dead.

Consonant class

Mid (9 letters), high (11) and low (24). The consonant index groups all 44 this way.

Live syllable

Ends in a long vowel or in m, n, ng, w, y. The sound can be held. มา maa, กิน kin.

Dead syllable

Ends in a short vowel or in a stop: k, t, p. It cuts off. จะ ja, รัก rak.

Put those two together with the tone mark and you can read the tone of a word you have never seen. Here is how.

Play them back to back

The difference stops being theoretical about four plays in. Open two tones at once and go down them in turn, rather than trying to hold one in your head.

Hearing them is a separate job from knowing them

The Sabai Thai game hub, listing Falling Words, Tone Tap, Word Match Rush, Tone Boss with five guardians one per tone, and Thai Mystery.

You can learn the five contours off this page in an afternoon. Telling them apart at speaking speed is ear training, and ear training is repetition, which is unbearable unless something makes it bearable.

So two of the app's five games are about nothing else. Tone Boss is one boss per tone and you beat it by hearing which one you were given. Tone Tap is the same job against a clock.

Both are available to explore on this website for free. The rest of what it does.
