Thai Tone Frequency and Syllable Length

One aspect of the Thai Alphabet cards which we chose to display a tone frequency and syllable duration marker as a colored line across a two dimensional grid.

Method of Tone Frequency and Syllable Length Display

First, we used the Tone Shape and Approximate Frequency adapted from Naksakul (1977:106) found on page 7 of Elementary Thai for Foreigners, authors Somsonge Burusphat, Sujaritlak Deepadung, Sukhuma-Vadee khamhiran, Mahidol University, 1991.

Relative Length of Long and Short Syllables

Second, we added relative lengths to the short and long syllables, which added information. In Naksakul (1977) we are provided with a mapping of tone frequencies relative to their duration. However, (and here generally speaking, but not precisely) there are at least both short and long syllables. It appears that each tone can be both long or short, which gives 10 possible tone/length combinations.

Our modification of the frequency displays was merely to shorten the tone at the 50% mark, that is, to compress the frequency shape into half the time. This is clearly a simplification but is most helpful in terms of visually seeing and learning long and short syllables, something that is especially difficult for Native English speakers, along with the tones themselves.

Modification of Mid-Tone Short Syllable

One adaptation we made was to the short mid-tone. It appeared visually as if it had a slight downward trajectory, but upon listening to native speakers that is not accurate. We decided that the tone frequency was being truncated before finishing. We revised this image by segmenting at the 75% mark of the long tone, and then shortening the tone length as we had done with all other short tones.

Pronunciation – Thai Low Consonants – Set 3

There are Twenty-four Low consonants in Thai. Some are less common than others but all are used in some words. In a few cases the letters are common in place names and Thai names and nicknames. It is common to learn Low consonants in sets (we choose to do 3 sets of 8 consonants, in alphabetical order), and to start the Low consonants after the first set of 7 common Mid consonants.

The third set of 8 Low Consonants

  • #32 - ภอ สำเภา - pau sam pao
  • #33 - มอ ท้า - mau maa
  • #34 - ยอ ยักษ์ - yau yag
  • #35 - รอ เรือ - rau ru-ah
    • Note: this is a rolling "r" such as found in Spanish, and not pronounced like an "r" in English
  • #36 - ลอ ลิง - lau ling
  • #37 - วอ แหวน - wau waayn
  • #42 - ฬอ จุฬา - lau ju laa
  • #44 - ฮอ นกฮูก - hau nog hoog

Pronunciation Practice – Thai Low Consonants – Set 1

There are Twenty-four Low consonants in Thai. Some are less common than others but all are used in some words. In a few cases the letters are common in place names and Thai names and nicknames. It is common to learn Low consonants in sets (we choose to do 3 sets of 8 consonants, in alphabetical order), and to start the Low consonants after the first set of 7 common Mid consonants.

The first set of 8 Low Consonants

  • #4 - คอ ควาย - kau kwaai
  • #5 - ฅอ ฅน - kau khon (change from "kon")
  • #6 - ฆอ ระฆัง - kau ra kang
  • #7 - งอ งู - ngau ngoo
  • #10 - ชอ ช้าง - shau shaang
    • Note: Thai people do not make the same sound as an English "ch" or "sh". The way the sound is produced (place and manner of articulation) is different. We will discuss this more in full in a future article.
  • #11 - ซอ โซ่ - sau soh
  • #12 - ฌอ เฌอ - shau shuhh (chang from "shuh")
  • #13 - ญอ หญิง - yau ying

Pronunciation Practice – First Set of Mid-Consonants

The First Set of Consonants to Learn

It is common to begin learning the Thai consonants in groups rather than in a linear fashion. The first set of consonants learned is generally the common mid-consonants. Seven of the nine Mid-Consonants are common, while two are uncommon and rarely used. Those are left for later. The idea is to learn consonants which can be built upon in terms of using vowels and creating words.

  • Purchase the Thai Alphabet Flash Cards

  • 1 Gau Gai - กอ ไก่

  • #8 Jau Jaan - จอ จาน
  • #20 Dau Deg - ดอ เด็ก
  • #21 Dtau Dtao - ตอ เต่า
  • #26 Bau Bai Mai - บอ ใบไมั
  • #27 Bpau Bplaa - ปอ ปสา
  • #43 Au Aang - ออ อ่าง

We use the Lanna Innovation Thai Consonant cards for this practice.

Thai Consonant Tone and Pronunciation Practice

The first set of Thai Alphabet Cards is the 44 Thai Consonants. Below we have simple pronunciation drills for each of the cards, divided into four videos of around 3 minutes each.

01 - Gau Gai - Thai Alphabet Consonants - How to Learn Thai

Pronunciation Practice Drills

Each video has a female speaker who pronounces a consonant three times, and then a male speaker. Each of the speakers is a Thai native speaker who is using standard Thai pronunciation.

Each video is available in HD so click on the HD button at the bottom of the player and size for a full-screen view to be able to read all details on the Thai consonant flash cards.

Tones and Syllable Length

Two key factors beyond making the correct sound (place and manner of articulation of the mouth and larynx), it is helpful to track the tones against the graphical tone indicators (the lines underneath the English phonetic transcription). These show the relative frequency of tone as well as the duration (length of the line).

Thai Consonants 1-11

Thai Consonants 12-23

Thai Consonants 24-34

Thai Consonants 35-44
