Rules for Transcribing English Words (into Thai)

Introduction

The official governing body of the Thai language, The Royal Institute, has recognized the importance of adopting foreign words such as names and specialized scientific terms into the Thai language. Such words are spoken such that the foreign phonemes are approximated within the Thai phonetic landscape. With the aim of providing consistent spelling of these loanwords, The Royal Institute has also promulgated the following guidelines for rendering English words in Thai script, a process called (phonemic) transcription1 of English.

The comparison tables referenced in this document are available via the following links:
Comparison Table - English Vowel Sounds
Comparison Table - English Consonant Sounds

 

Explanation
¤ÓªÕéᨧ khahmM cheeH jaaengM

1.The original English word should be transcribed in a such a manner as to indicate the original form of the word as well as to allow the word to be written in a manner so that it might be easily read in Thai script. ñ.¡Ò÷ѺÈѾ·ìãËé¶Í´ÍÑ¡ÉÃã¹ÀÒÉÒà´ÔÁ¾Í¤ÇÃá¡è¡ÒÃáÊ´§·ÕèÁҢͧÃÙ»ÈѾ·ì áÅÐãËéà¢Õ¹ã¹ÃÙ»·ÕèÍèÒ¹ä´éÊдǡã¹ÀÒÉÒä·Â

2.Setting forth these conventions distinguishes and determines transcription rules for various languages.2 ò.¡ÒÃÇÒ§ËÅѡࡳ±ìä´éá¡¡Ó˹´ËÅѡࡳ±ì¡Ò÷ѺÈѾ·ìÀÒÉÒµèÒ§ æ áµèÅÐÀÒÉÒä»

3.Some transcribed words have been used (by Thais) for so long that they are considered Thai words and are already included in the Royal Institute Dictionary of the Thai Language. These transcribed forms should continue to be utilized. Such words include the Thai words for “chocolate,” “shirt,” and “gas.” ó.¤Ó·ÑºÈѾ·ì·Õèãªé¡Ñ¹ÁÒ¹Ò¹¨¹¶×Íà»ç¹ÀÒÉÒä·Â áÅлÃÒ¡¯ã¹¾¨¹Ò¹Ø¡ÃÁ©ºÑºÃÒªºÑ³±ÔµÂʶҹáÅéÇ ãËéãªé µèÍ仵ÒÁà´ÔÁ àªè¹ ªçÍ¡â¡àŵ ªçÍ¡â¡áŵ àªÔéµ ¡êÒ« á¡êÊ

4.Proper nouns whose transcriptions have a long historical usage shall continue to be utilized (even though such transcriptions may not conform to these new principles), for example: ô.¤ÓÇÔÊÒÁҹ¹ÒÁ·Õèãªé¡Ñ¹ÁÒ¹Ò¹áÅéÇ ÍÒ¨ãªéµèÍ仵ÒÁà´ÔÁ àªè¹

5.These rules may be supplemented as necessary for technical words which are used by specific communities and which are not words in general usage. õ.ÈѾ·ìÇÔªÒ¡ÒëÖè§ãªé੾ÒÐ¡ÅØèÁ äÁèãªèÈѾ·ì·ÑèÇä» ÍÒ¨à¾ÔèÁàµÔÁËÅѡࡳ±ì¢Öé¹µÒÁ¤ÇÒÁ¨Óà»ç¹

These are the principles:

1.For vowels, Thai letters used should imitate the sounds reflected in English language dictionaries using the Comparison Table - English Vowel Sounds ñ.ÊÃÐ ãËé¶Í´µÒÁ¡ÒÃÍÍ¡àÊÕ§㹾¨¹Ò¹Ø¡ÃÁÀÒÉÒÍѧ¡ÄÉ â´Âà·ÕºàÊÕ§ÊÃÐÀÒÉÒä·ÂµÒÁµÒÃÒ§à·ÕºàÊÕ§ÊÃÐÀÒÉÒÍѧ¡ÄÉ

2.For consonants, the Thai letters used should be those from the Comparison Table - English Consonant Sounds ò.¾ÂÑ­ª¹Ð ãËé¶Í´à»ç¹¾ÂÑ­ª¹ÐÀÒÉÒä·ÂµÒÁËÅѡࡳ±ìã¹µÒÃÒ§à·Õº¾ÂÑ­ª¹ÐÀÒÉÒÍѧ¡ÄÉ

3.When to use a silencer mark:3 ó.¡ÒÃãªéà¤Ã×èͧËÁÒ·ѳ±¦Òµ
gaanM chaiH khreuuangF maayR thanM thaH khaatF
3.1.Consonants sounds (in the English word) which are not pronounced in Thai should be marked with a silencer, for example: ó.ñ.¾ÂÑ­ª¹ÐµÑÇ·ÕèäÁèÍÍ¡àÊÕ§ã¹ÀÒÉÒä·Â ãËéãÊèà¤Ã×èͧËÁÒ·ѳ±¦Òµ¡Ó¡ÑºäÇé àªè¹

Windsor ÇÔ¹´ìà«ÍÃì  /win[d]M suuhrM/
3.2.In a word or syllable which has several final consonants, one should use a silencer only on the very last consonant which is not sounded out, for example: ó.ò.¤ÓËÃ×;ÂÒ§¤ì·ÕèµÑÇÊС´ÁÕ¾ÂÑ­ª¹ÐµÒÁÁÒËÅÒµÑÇ ãËéãÊèà¤Ã×èͧËÁÒ·ѳ±¦Òµ äÇ麹¾ÂÑ­ª¹Ð·ÕèäÁèÍÍ¡àÊÕ§µÑÇÊØ´·éÒÂáµèà¾Õ§áËè§à´ÕÂÇ àªè¹

3.3.In a word or syllable which has consonants which are not pronounced, which are placed before the final consonant, and where there are consonants following, such non-pronounced consonants should be cut out and a silencer inserted over the final, non-pronounced consonant. For example: ó.ó.¤ÓËÃ×;ÂÒ§¤ì·ÕèÁÕ¾ÂÑ­ª¹ÐäÁèÍÍ¡àÊÕ§ÍÂÙè˹éÒµÑÇÊС´ ·ÕèÂѧÁÕ¾ÂÑ­ª¹ÐµÒÁËÅѧÁÒÍÕ¡ ãËéµÑ´¾ÂÑ­ª¹Ð·ÕèÍÂÙè˹éÒµÑÇÊС´ÍÍ¡ áÅÐãÊèà¤Ã×èͧËÁÒ·ѳ±¦ÒµäÇ麹¾ÂÑ­ª¹ÐµÑÇÊØ´·éÒ àªè¹

quartz ¤Ç͵«ì  /khwaawt[s]F/
Johns ¨Í¹Êì  /jaawn[s]M/

4.The short vowel marker is used in the following cases: ô.¡ÒÃãªéäÁéäµè¤Ùé ¤ÇÃãªé㹡óյèÍ仹Õé
gaanM chaiH maaiH dtaiL khuuH khuaanM chaiH naiM gaL raH neeM dtaawL bpaiM neeH
4.1.In order to differentiate the English word from an existing Thai word: ô.ñ.à¾×èÍãËéàËç¹áµ¡µèÒ§¨Ò¡¤Óä·Â àªè¹
pheuuaF haiF henR dtaaekL dtaangL jaakL khahmM thaiM chehnF
log ÅçÍ¡  /lawkH/
4.2.In order to allow the reader to correctly divide the syllables of the word. Example: ô.ò.à¾×èͪèÇÂãËé¼ÙéÍèҹ᡾ÂÒ§¤ìä´é¶Ù¡µéͧ àªè¹
pheuuaF chuayF haiF phuuF aanL yaaekF phaH yaang[k]M daiF thuukL dtaawngF chehnF
Okhotsk âͤçÍµÊ¡ì  /ohM khawtH/
5.The use of tone markers: In transcribing from English to Thai, one need not insert tone markers, except in cases in which such transcribed word replicates the sound of an existing Thai word which might create confusion for the reader. In these cases it is appropriate to use a tone marker for example: õ.¡ÒÃãªéà¤Ã×èͧËÁÒÂÇÃÃ³ÂØ¡µì ¡ÒÃà¢Õ¹¤Ó·ÑºÈѾ·ì äÁèµéͧãÊèà¤Ã×èͧËÁÒÂÇÃÃ³ÂØ¡µì ¡àÇé¹ã¹¡Ã³Õ·Õè¤Ó¹Ñé¹ÁÕàÊÕ§«éӡѺ¤Óä·Â ¨¹·ÓãËéà¡Ô´¤ÇÒÁÊѺʹ ÍÒ¨ãÊèà¤Ã×èͧËÁÒÂÇÃÃ³ÂØ¡µìä´é àªè¹

coke â¤é¡  /khohkH/
coma â¤ÁèÒ  /khohM maaF/
6.Double-letters: For English words which have double letters as finals, if such word is a common noun, one of the double letters is removed, for example: ö.¾ÂÑ­ª¹Ð«é͹ ¤Ó·ÕèÁÕ¾ÂÑ­ª¹Ð«é͹à»ç¹µÑÇÊС´ ¶éÒà»ç¹ÈѾ·ì·ÑèÇä»ãËéµÑ´ÍÍ¡µÑÇ˹Öè§ àªè¹

football ¿ØµºÍÅ  /footH baawnM/
However, if such word is a technical term or is a proper noun, the double letters are retained and a silencer is placed over the second letter, for example: áµè¶éÒà»ç¹ÈѾ·ì·Ò§ÇÔªÒ¡ÒÃËÃ×ÍÇÔÊÒÁҹ¹ÒÁãËéà¡çºäÇé·Ñé§ ò µÑÇ â´ÂãÊèà¤Ã×èͧËÁÒ·ѳ±¦ÒµäÇé·ÕèµÑÇ·éÒ àªè¹

cell à«ÅÅì  /saehn[l]M/
James Watt à¨ÁÊì Çѵµì  /jaehm[s]M wat[d]H/
If the double letters occur in the middle of the word, the rules are: the first letter of the double is the last consonant of the prior syllable and the second consonant is the initial of the next syllable. Therefore, the expression of the first and second letters of the double will differ according to the rules set forth in the Consonant Table, for example: ¶éÒ¾ÂÑ­ª¹Ð«é͹ÍÂÙè¡ÅÒ§ÈѾ·ìãËé¶×ÍÇèÒ ¾ÂÑ­ª¹Ð«é͹µÑÇááà»ç¹µÑÇÊС´¢Í§¾ÂÒ§¤ì˹éÒ áÅоÂÑ­ª¹Ð«é͹µÑÇËÅѧà»ç¹¾ÂÑ­ª¹Ðµé¹¢Í§¾ÂÒ§¤ìµèÍä» ©Ð¹Ñé¹ ¡ÒÃãªé¾ÂÑ­ª¹ÐµÑÇÊС´áÅоÂÑ­ª¹Ðµé¹ ¨ÐµèÒ§¡Ñ¹µÒÁËÅѡࡳ±ì¡ÒÃà·Õº¾ÂÑ­ª¹Ðã¹µÒÃÒ§¢éÒ§·éÒ àªè¹

7.In a word in which the final consonant of a syllable also serves to sound out of the subsequent syllable, the following rules apply: ÷.¤Ó·ÕèµÑÇÊС´¢Í§¾ÂÒ§¤ì˹éÒÍÍ¡àÊÕ§à»ç¹¾ÂÑ­ª¹Ðµé¹¢Í§¾ÂÒ§¤ìµÑǵèÍä»´éÇ ãËé¶×ÍËÅѡࡳ±ì´Ñ§¹Õé

7.1.If the vowel associated with the first syllable is an /-a-/ sound which uses the "stick turning in air" vowel in the transcription, one should double the transcribed consonant for use again as the initial consonant in the subsequent syllable, for example: ÷.ñ.¶éÒÊÃТͧ¾ÂÒ§¤ì˹éÒà»ç¹àÊÕ§ÊÃÐÍÐ «Öè§àÁ×èͷѺÈѾ·ìµéͧãªéÃÙ»äÁéËѹÍÒ¡ÒÈ ãËé«é͹¾ÂÑ­ª¹ÐµÑÇÊС´¢Í§¾ÂÒ§¤ì˹éÒà¢éÒÍÕ¡µÑÇ˹Öè§à¾×èÍà»ç¹¾ÂÑ­ª¹Ðµé¹¢Í§¾ÂÒ§¤ìµèÍä» àªè¹

double ´ÑºàºÔÅ  /dapL beernM/
7.2.If the vowel associated with the first syllable is any vowel other than /-a-/, the consonant should be transcribed using the English consonant itself without doubling up the consonant, for example: ÷.ò.¶éÒÊÃТͧ¾ÂÒ§¤ì˹éÒà»ç¹ÊÃÐÍ×è¹·ÕèäÁèãªèÊÃÐÍÐ ãËé·ÑºÈѾ·ìµÒÁÃÙ»¾ÂÑ­ª¹ÐÀÒÉÒÍѧ¡ÄÉâ´ÂäÁèµéͧ«é͹¾ÂÑ­ª¹Ð àªè¹

California á¤ÅÔ¿ÍÃìà¹Õ  /khaaeM liH faaw[r]M niiaM/
general à¨à¹ÍÃÑÅ  /jaehM nuuhrM ranM/
7.3.If the word is one which arises from the use of a suffix such as -er, -ing, -ic, or –y and the use of rule 7.2 above results in a sound significantly at variance with the original English word, one should double the final consonant in order to be able to recognize the source of the original word, for example: ÷.ó.¶éÒà»ç¹¤Ó·Õèà¡Ô´¨Ò¡¡ÒÃàµÔÁ»Ñ¨¨Ñ àªè¹ -er, -ing, -ic, or –y áÅСÒ÷ѺÈѾ·ìµÒÁÃÙ»¾ÂÑ­ª¹ÐÀÒÉÒÍѧ¡Äɴѧ¢éÍ ÷.ò ÍÒ¨·ÓãËéÍÍ¡àÊÕ§¼Ô´ä»¨Ò¡ÀÒÉÒà´ÔÁÁÒ¡ ãËé«é͹¾ÂÑ­ª¹ÐµÑÇÊС´¢Í§¾ÂÒ§¤ìµé¹Íա˹Öè§à¾×èÍãËéàËç¹à¤éÒ¤Óà´ÔÁ àªè¹

8.One should transcribe hyphenated words as one continuous word, for example: ø.¤Ó»ÃÐÊÁ·ÕèÁÕà¤Ã×èͧËÁÒÂÂѵÔÀѧ¤ì ãËé·ÑºÈѾ·ìâ´Âà¢Õ¹µÔ´µèÍ¡Ñ¹ä» àªè¹

9.Compound words which in English are written as separate words should be transcribed as a single word which need not be separated by a space, for example: ù.¤Ó»ÃÐÊÁ«Öè§ã¹ÀÒÉÒÍѧ¡ÄÉà¢Õ¹á¡¡Ñ¹ àÁ×èͷѺÈѾ·ìãËéà¢Õ¹µÔ´¡Ñ¹ä» äÁèµéͧᡤӵÒÁÀÒÉÒà´ÔÁ àªè¹

10.For adjectives derived from nouns which present difficulty as to whether they should be transcribed as nouns or adjectives, one should use the following rules: ñð.¤Ó¤Ø³ÈѾ·ì·ÕèÁÒ¨Ò¡¤Ó¹ÒÁ «Öè§ÁջѭËÒÇèҨзѺÈѾ·ìã¹ÃÙ»¤Ó¹ÒÁËÃ×ͤӤسÈѾ·ì¹Ñé¹ ãËé¶×ÍËÅѡࡳ±ì´Ñ§¹Õé

10.1.If the adjective has the same meaning as the associated noun, or carries the meaning of “is an element of” or “is about” the noun, the adjective should be transcribed in the same form as the noun, for example: ñð.ñ.¶éҤӤسÈѾ·ì¹Ñé¹ÁÕ¤ÇÒÁËÁÒÂàËÁ×͹¤Ó¹ÒÁ ËÃ×ÍËÁÒ¤ÇÒÁÇèÒ "à»ç¹¢Í§" ËÃ×Í "à»ç¹àÃ×èͧ¢Í§" ¤Ó¹ÒÁ¹Ñé¹ ãËé·ÑºÈѾ·ìã¹ÃÙ»¤Ó¹ÒÁ àªè¹
