This function converts Thai text into phonetic code.

:Options for engine:
* *udom83* (default) - Thai soundex algorithm proposed
by Vichit Lorchirachoonkul [#udom83]_
* *lk82* - Thai soundex algorithm proposed by
Wannee Udompanich [#lk82]_
* *metasound* - Thai soundex algorithm based on a combination
of Metaphone and Soundex proposed by Snae & Brückner [#metasound]_
* *prayut_and_somchaip* - Thai-English Cross-Language Transliterated
Word Retrieval using Soundex Technique [#prayut_and_somchaip]_
