Initial Consonant Phones
In Thai, there are twenty-one consonant sounds which may occur at the beginning of a syllable. Any one of the forty-four Thai consonant graphemes can be used in syllable-initial position. The 21 sounds can be divided into three types according to their phonetic characterics: sonorant, plain, and aspirate. As you can see in the following table, doing so will help you remember the consonant class of each consonant grapheme. This information is required for applying the Thai tone rules.
