What's a Tonal Language?

In English and many other Western languages of the world, you can say a given word with many different pitches of voice, (say it to yourself: "He's cold." "Is he cold?" "I'm freakin' cold!") but it is still the same word. The pitch of your voice does impart meaning to the sentence (e.g. asking a question, being emphatic) but it does not change the meaning of the word itself.

The Thai language is tonal, meaning that when you speak a word, the pitch of your voice is an integral part of that word. If you speak with the wrong pitch, you are saying a different word.

For example, in Thai, the word that sounds (roughly) like "maa" means "to come", but the word that sounds (roughly) like "maa?" means "dog" or "horse" depending on how you say it!

Thai Has Five Tones

In total, Thai has five tones, named "mid," "low," "falling," "high," and "rising." While they're a good start, these names are nowhere near enough information to really understand what the tones sound like. Adding insult to injury is that when you ask a Thai to demonstrate a given tone for you, he or she will often exaggerate it to the point where it is no longer useful as an example!

In this document, you can listen to some real-world examples of tones, and even better, you can visualize those tones using a type of chart called a spectrogram. You can even use our Voice Viewer tool to see the spectrogram of your own voice and compare it with the model! Read on...

Spectrograms

This page uses colorful charts called spectrograms to help explain the tones of Thai.

To understand how a spectrogram works, first click the little play button at the left end of the player bar below to hear a silly sound:

If you have a slow internet connection, you may have to wait a little bit before the sound plays.

If the player is playing (the seconds are counting up and the bar is making its way to the right) but you still don't hear any sound, you need to adjust the volume on your computer. You might also need to turn up the volume on the right end of the player bar above. Or, reach under the desk and see that your headphones are actually unplugged :)

A spectrogram plots that silly sound over time like this:

Click the play button of the player bar below the spectrogram and you will hear the silly sound again. Or, you can click anywhere in the image itself or in the player bar to start playing at that point.

Notice how the vertical position of the colorful curve in the plot follows the pitch of the silly sound. Sounds that are lower in pitch are near the bottom of the chart, and sounds that are higher in pitch are near the top of the chart.

Notice the blue fuzz at the bottom: that is the very low-pitched, wind-like blowing sound you can also hear along with the whistling.

The color of the spectrogram at a given point indicates how much sound with that pitch you were making at that time. The color scale works like this:

So the red parts of the spectrogram represent the most noticeable pitches.

Voice Viewer: See Your Own Spectrogram and Compare!

Here at slice-of-thai.com, we offer:

Voice Viewer

a free software tool you can use to see the spectrogram of your own voice as you speak into a microphone.

We recommend that you get Voice Viewer and use it to compare the sounds of your own voice with the samples on this page!

Looking at the Five Tones of Thai

Ok, now we're equipped to learn about the tones.

Here is a sound clip and spectrogram of how native Thai speakers pronounce the 5 tones:

Bring up a window with Voice Viewer running and then see if you can produce these shapes with your own voice.

Remember it's the overall contour of each tone that you want to imitate. If your shapes look like these but they're just stretched out or scrunched up horizontally, then you're ok. It just means you spoke more slowly or more quickly than the picture.

If you have any trouble gettting Voice Viewer to work, or to produce pictures like these, check out our Voice Viewer troubleshooting section.

How High? How Low?

The mid tone has whatever comfortable pitch you normally use when speaking. The other tones are relative to that. So, two speakers may utter the same tones using very different pitches. For example, here's a sound clip and spectrogram of a native female speaker (stolen from the wonderful SEAsite at http://www.seasite.niu.edu) followed by me:

We are both speaking the same tones, and we both use roughly the same patterns (that is, the shape of my 5 syllables on the spectrogram roughly matches hers), but the pitches are quite different (my syllables on the spectrogram are shifted down relative to hers).

Here's another native speaker example, for comparison:

Details and Examples

Mid Tone

[bpaa, bpaa, ปา^M, bpaaM, pbah, ˈpaa, ˈpaː, pā^M, ˈbpah, paa, bpaa, pa] [ปา^M]

As mentioned above, the mid tone has whatever comfortable pitch you usually use to speak English. Textbooks will tell you that the mid tone is not supposed to rise or fall. In a native Thai speaker's normal, fluent speech, and in the mid tone examples with my voice above, the mid tone remains at a steady pitch as expected.

You Had to Ask

However, I have found that if you ask nearly any Thai native to demonstrate the mid tone to you, their voice will start at the expected, comfortable pitch, but then it will sometimes rise a tiny bit, and then it will always fall somewhat at the end. I've watched about 30 native English speakers learn Thai, and this has confused every one of them. We easily mistake this "exaggerated" mid tone for the falling tone. Don't be confused. There are not 6 tones in Thai; they're just trying to be "clearer" by exaggerating the tone in this way. You can tell it's a mid tone because it starts at the speaker's normal comfortable pitch, as opposed to a falling tone which starts at an unusually high pitch for the speaker.

We heard one example just above (the SEAsite speaker). Notice how the spectrogram of her "mid" tone falls at the end. Here's another example, where we'll hear the "textbook" mid tone as we poor English speakers expect it, followed by the "exaggerated" mid tone we hear from native Thai speakers, followed by a real falling tone for reference:

Sample words:

มา [maa, maa, มา^M, maaM, mah, ˈmaa, ˈmaː, mā^M, ˈmah, maa, maa, ma]
ดี [dii, dii, ดี^M, deeM, dee, ˈdii, ˈdiː, dī^M, ˈdee, dii, dee, di]
ไกล [glai, glai, ไกฺล^M, glaiM, glai, ˈklay, ˈklaj, klai^M, ˈglai, klai, glai, klai]
ทาง [taang, taang, ทาง^M, thaangM, tahng, ˈthaaŋ, ˈtʰaːŋ, thāŋ^M, ˈtahng, thaang, taang, thang]

Low Tone

[bpàa, bpàa, ป่า^L, bpaaL, pbàh, ˈpàa, ˈpàː, pā^L, ˈbpàh, pàa, bpàa, pà] [ป่า^L]

This tone starts at a very low pitch. To make your speech clear, pick the lowest pitch you can comfortably make with your voice (and wish that native Thai speakers would do the same). Like the mid tone, our textbooks tell us that the low tone is not supposed to change in pitch at all. However, as seen in all the spectrograms above (the native speaker and me), your natural tendency will be to have some sort of very fast descent down to the low pitch at the beginning of your syllable. This is ok. You can tell the syllable is a low tone because it starts at or below the speaker's comfortable pitch and goes very low (lower even than the "exaggerated" mid tone).

Sample words:

ข่า [kàa, kàa, ข่า^L, khaaL, kàh, ˈkhàa, ˈkʰàː, khā^L, ˈkàh, khàa, kàa, khà]
ติ [dtì, dtì, ติ^L, dtiL, dtì, ˈtì, ˈtì, ti^L, ˈdtì, tì, dtì, tì]
เก็บ [gèp, gèp, เก็บ^L, gepL, gèp, ˈkèp, ˈkèp, kep^L, ˈgèp, kèp, gèp, kèp]
เขต [kèet, kèet, เขด^L, khaehtL, kàyt, ˈkhèet, ˈkʰèːt, khēt^L, ˈkàyt, khèht, kàyt, khèt]

Falling Tone

[bpâa, bpâa, ป้า^F, bpaaF, pbâh, ˈpâa, ˈpâː, pā^F, ˈbpâh, pâa, bpâa, pâ] [ป้า^F]

This tone should be called the "start your voice a lot higher than you normally speak and slide down to a lot lower than you normally speak" tone. Thai speakers recognize this tone because it starts very high and falls.

Sample words:

ค่า [kâa, kâa, ค่า^F, khaaF, kâh, ˈkhâa, ˈkʰâː, khā^F, ˈkâh, khâa, kâa, khâ]
บ้าน [bâan, bâan, บ้าน^F, baanF, bâhn, ˈbâan, ˈbâːn, bān^F, ˈbâhn, bâan, bâan, bân]
พูด [pûut, pûut, พูด^F, phuutF, pôot, ˈphûut, ˈpʰûːt, phūt^F, ˈpôot, phûut, pôot, phût]
ใกล้ [glâi, glâi, ไกฺล้^F, glaiF, glâi, ˈklây, ˈklâj, klai^F, ˈglâi, klâi, glâi, klâi]
มั่น [mân, mân, มั่น^F, manF, mân, ˈmân, ˈmân, man^F, ˈmûn, mân, mân, mân]
เตี้ย [dtîia, dtîa, เตี้ย^F, dtiiaF, dtêea, ˈtîa, ˈtîːa, tīa^F, ˈdtêe-a, tîa, dtîa, tîa]

High Tone

[bpáa, bpáa, ป๊า^H, bpaaH, pbáh, ˈpáa, ˈpáː, pā^H, ˈbpáh, páa, bpáa, pá] [ป๊า^H]

This tone should be called the "start your voice a lot higher than you normally speak and slide it up even a little bit higher" tone. There's one simple rule here: If you don't feel like a chipmunk while trying to speak this tone, you're doing it wrong!

At all times, your voice should be unusually high for your normal speech. You must start high because otherwise a Thai person will think you're speaking a rising tone.

Sample words:

ท้าย [táai, táai, ท้าย^H, thaaiH, táai, ˈtháay, ˈtʰáːj, thāi^H, ˈtái, thái, táai, thái]
คิด [kít, kít, คิด^H, khitH, kít, ˈkhít, ˈkʰít, khit^H, ˈkít, khít, kít, khít]
รั้ว [rúua, rúa, รั้ว^H, ruaaH, róoa, ˈrúa, ˈrúːa, rūa^H, ˈróo-a, rúa, rúa, rúa]
เล็ก [lék, lék, เล็ก^H, lekH, lék, ˈlék, ˈlék, lek^H, ˈlék, lék, lék, lék]
น้อย [nɔ́ɔi, nɔ́ɔi, น้อย^H, naawyH, náwy, ˈnɔ́ɔy, ˈnɔ́ːj, nǭi^H, ˈnói, náwy, nói, nói]

Rising Tone

[bpǎa, bpǎa, ป๋า^R, bpaaR, pbǎh, ˈpǎa, ˈpǎː, pā^R, ˈbpǎh, pǎa, bpǎa, pǎ] [ป๋า^R]

This tone should be called the "start your voice a lot lower than you normally speak and slide it up higher than you normally speak" tone. It can be similar to what English speakers do when we ask a yes/no question, as in the word "Thai" in "Is he a Thai?"

I have found that many Thai speakers really draw out their rising tones even in normal, fluent speech, which suggests it's important to do so to distinguish the rising tone from the high tone.

Sample words:

หมา [mǎa, mǎa, หฺมา^R, maaR, mǎh, ˈmǎa, ˈmǎː, mā^R, ˈmǎh, mǎa, mǎa, mǎ]
ขา [kǎa, kǎa, ขา^R, khaaR, kǎh, ˈkhǎa, ˈkʰǎː, khā^R, ˈkǎh, khǎa, kǎa, khǎ]
หาว [hǎao, hǎao, หาว^R, haaoR, hǎo, ˈhǎaw, ˈhǎːw, hāo^R, ˈhǎo, hǎo, hǎao, hǎo]
หญิง [yǐng, yǐng, หฺยิง^R, yingR, yǐng, ˈyǐŋ, ˈjǐŋ, yiŋ^R, ˈyǐng, yǐng, yǐng, yǐng]
ตั๋ว [dtǔua, dtǔa, ตั๋ว^R, dtuaaR, dtǒoa, ˈtǔa, ˈtǔːa, tūa^R, ˈdtǒo-a, tǔa, dtǔa, tǔa]
ผิว [pǐu, pǐu, ผิว^R, phiuR, pěw, ˈphǐw, ˈpʰǐu, phiu^R, ˈpěe-oo, phǐu, pǐw, phǐo]
แจ๋ว [jɛ̌o, jɛ̌o, แจ๋ว^I^S^R, jaeoR, jǎeo, ˈcɛ̌w, ˈtɕɛ̌w, čhæo^R, ˈjǎir-o, jǎew, jǎew, chǎeo]

Disappearing Tones

Although few Thais will admit it, you will find that sometimes all evidence of tones completely disappears for certain syllables in fluent Thai speech. This is particularly the case for common words. For example, when it's time for breakfast, few Thais will order the sensible sounding dish on the left. Instead, they will compress it into the morsel on the right:

The vowel [aao, aao, อาว^M, aaoM, ao, ˈʔaaw, ˈʔaːw, ʿāo^M, ˈao, ao, aao, ao] has virtually disappeared, along with the highly useful falling tone that we non-native speakers use to distinguish the many words which sound like [kaao, kaao, คาว^M, khaaoM, kao, ˈkhaaw, ˈkʰaːw, khāo^M, ˈkao, khao, kaao, khao]. Interestingly, the [dtôm, dtôm, ต้ม^F, dtohmF, dtôm, ˈtôm, ˈtôm, tom^F, ˈdtôm, tôm, dtôm, tôm] remains undamaged. I have seen that this shortening often happens to all but the last syllable of words.

These shortening patterns can be utterly confounding for a person trying to learn and understand Thai. Fortunately, there are not very many of them, and you will learn them by trial and error.

Another very common pattern is the shortening of the negative [mâi, mâi, ไม่^F, maiF, mâi, ˈmây, ˈmâj, mai^F, ˈmâi, mâi, mâi, mâi]:

In this case, the vowel is very much still there, but it has changed from [mâi, mâi, ไม่^F, maiF, mâi, ˈmây, ˈmâj, mai^F, ˈmâi, mâi, mâi, mâi] to a short [mé, mé, เมะ^H, mehH, mé, ˈmé, ˈmé, me^H, ˈmé, mé, mé, mé]. Since it's so short, its tone has effectively been changed into a high tone (and you really won't get any Thais to admit that!). The negative [mâi, mâi, ไม่^F, maiF, mâi, ˈmây, ˈmâj, mai^F, ˈmâi, mâi, mâi, mâi] is not always shortened in this way. It seems to depend on the word which follows (perhaps on the initial consonant of the word which follows). For example, [mâi-dii, mâi-dii, ไม่^F-ดี^M, maiF-deeM, mâi-dee, ˈmây ˈdii, ˈmâj ˈdiː, mai^F-dī^M, ˈmâi ˈdee, mâi-dii, mâi-dee, mâi-di] (not good) doesn't seem to be shortened in the same way as often.

Unstressed Tones

Syllable stress is another factor that can make the actual tones you hear differ from what you expect. Even though Thai is tonal, it still has stressed and unstressed syllables like English does. Stressed syllables generally sound like the tone that is written, but (as in English) unstressed syllables tend to get slurred in normal, everyday, fluent speech. In particular, Thais tend to say unstressed syllables with a mid, tone rather than the tone that is written.

For example, the first syllable of these two words is unstressed, and so Thais generally say it with a mid tone rather than the tone you'd expect from the spelling:

หนังสือ [nǎng~sʉ̌ʉ, nǎng~sʉ̌ʉ, หฺนัง^R~สือ^R, nangR~seuuR, nǎng~sǔe, nǎŋ ˈsʉ̌ʉ, nǎŋ ˈsɯ̌ː, naŋ^R~sư̄^R, nǔng ˈsěu, nǎng~sěu, nǎng~sěu, nǎng~sǔe] (n. book) → [nang-sʉ̌ʉ, nang-sʉ̌ʉ, นัง^M-สือ^R, nangM-seuuR, nang-sǔe, ˈnaŋ ˈsʉ̌ʉ, ˈnaŋ ˈsɯ̌ː, naŋ^M-sư̄^R, ˈnung ˈsěu, nang-sěu, nang-sěu, nang-sǔe]
กระเทียม [grà~tiiam, grà~tiam, กฺระ^L~เทียม^M, graL~thiiamM, grà~teeam, krà ˈthiam, krà ˈtʰiːam, kra^L~thīam^M, grà ˈtee-am, krà~thiam, grà~tiam, krà~thiam] (n. garlic) → [grə-tiiam, grə-tiam, เกฺรอะ^I^M-เทียม^M, gruhM-thiiamM, grer-teeam, ˈkrə ˈthiam, ˈkrə ˈtʰiːam, krœ^M-thīam^M, ˈgrer ˈtee-am, kroe-thiam, gruh-tiam, kroe-thiam]
ฝรั่ง [fà~ràng, fà~ràng, ฝะ^L~หฺรั่ง^L, faL~rangL, fà~ràng, fà ˈràŋ, fà ˈràŋ, fa^L~raŋ^L, fà ˈrùng, fà~ràng, fà~ràng, fà~ràng] (n. non-Asian foreigner) → [fə-ràng, fə-ràng, เฟอะ^I^M-หฺรั่ง^L, fuhM-rangL, fer-ràng, ˈfə ˈràŋ, ˈfə ˈràŋ, fœ^M-raŋ^L, ˈfer ˈrùng, foe-ràng, fuh-ràng, foe-ràng]

How The Tones are Written

In the pronunciation guide systems, the tones are written with funny marks above the first vowel letter of each syllable, or after the last letter of each syllable, like so:

Guide System	Mid	Low	Falling	High	Rising
Paiboon+	[aa]	[àa]	[âa]	[áa]	[ǎa]
Paiboon	[aa]	[àa]	[âa]	[áa]	[ǎa]
Easy Thai	[อา^M]	[อ่า^L]	[อ้า^F]	[อ๊า^H]	[อ๋า^R]
TLC	[aaM]	[aaL]	[aaF]	[aaH]	[aaR]
Tiger	[ah]	[àh]	[âh]	[áh]	[ǎh]
Haas	[ˈʔaa]	[ˈʔàa]	[ˈʔâa]	[ˈʔáa]	[ˈʔǎa]
IPA	[ˈʔaː]	[ˈʔàː]	[ˈʔâː]	[ˈʔáː]	[ˈʔǎː]
ALA-LC	[ʿā^M]	[ʿā^L]	[ʿā^F]	[ʿā^H]	[ʿā^R]
TYT	[ˈah]	[ˈàh]	[ˈâh]	[ˈáh]	[ˈǎh]
LP	[aa]	[àa]	[âa]	[áa]	[ǎa]
T2E	[aa]	[àa]	[âa]	[áa]	[ǎa]
Thai Govt+	[a]	[à]	[â]	[á]	[ǎ]

The tone marks used for Paiboon, Paiboon+, Tiger, LP, Thai Govt+, and IPA systems are identical. If there is no mark (as in [aa], or an optional flat bar [ˈʔaː] for IPA only), then it is a "mid" tone: you speak at your normal pitch and do not rise or fall. Here is a cool memory aid for the other marks, from the venerable 1979 Chiang Mai AUA Reading Workbook (J. Marvin Brown, printed at least up until 1998 and possibly still in print; table reformatted and reordered from original typewritten manuscript):

The logic behind the use of the tonal markers is this: the first line of the symbol is like an arrow telling you where to start, and the second tells you what to do (if there is no second line, then you simply stay where you are):
Mark Memory Aid Tone
[àa] tells you to start low and stay there Low
[âa] tells you to start high and then to go low Falling
[áa] tells you to start high and stay there High
[ǎa] tells you to start low and then go to high Rising

Mark	Memory Aid	Tone
[àa]	tells you to start low and stay there	Low
[âa]	tells you to start high and then to go low	Falling
[áa]	tells you to start high and stay there	High
[ǎa]	tells you to start low and then go to high	Rising

For full Thai script (and the Easy Thai pronunciation guide), it's a little bit more complex. Here we'll show you the easy case. For middle consonants such as ก [gɔɔ-gài, gɔɔ-gài, กอ^M-ไก่^L, gaawM-gaiL, gaw-gài, ˈkɔɔ ˈkày, ˈkɔː ˈkàj, kǭ^M-kai^L, ˈgor ˈgài, kaw-kài, gor-gài, ko-kài] or อ [ɔɔ-àang, ɔɔ-àang, ออ^M-อ่าง^L, aawM-aangL, aw-àhng, ˈʔɔɔ ˈʔàaŋ, ˈʔɔː ˈʔàːŋ, ʿǭ^M-ʿāŋ^L, ˈor ˈàhng, aw-àang, or-àang, o-àng] with a long vowel and no final consonant, you use the following marks to get the five tones (in this case, no mark gives you a mid tone):

Mid Low Falling High Rising
อา อ่า อ้า อ๊า อ๋า

Mid	Low	Falling	High	Rising
อา	อ่า	อ้า	อ๊า	อ๋า

What about Thai syllables with other class initial consonants, short vowels, and/or final consonants?

For starters, be aware that having no mark doesn't always imply a mid tone, and that that the marks above imply different tones for syllables beginning with other classes of initial consonants.

Evolving Tones

In reality, the tones of Thai and all other languages are slowly evolving and changing over generations. For some recent research on this and some more detailed tone charts showing cross-generational differences in Bangkok, see this paper by Kanjana Thepboriruk.
