Formation of Standard Tibetan Syllables and Comparison as well as Analysis of the Statistical Results

Considering how best it can be designed and realized through computer, the combination of all types of letters as well as its prefix, root, superscript, subscript, vowel, suffix, and farther suffix that are contained in a syllable will be transcribed by Latin after carefully identifying the attributes of Tibetan word in the statistical form. All these component parts of a syllable keep to the rules that have to be followed in the process of combining all types of letters, thereby theoretically producing normative syllables that consist of one, two, three and four letters. Normative syllables that are made up of respectively one, two, three and four characters can be found in the following numbers separately 445, 4985, 7212, 2250 and these syllables amount to 14,982 when all put together. Statistical results of Tibetan normative syllables in language databank with a size of 50 megabyte appear in these following numbers respectively: 415 single-character syllables, 2475 double-character syllables, 2423 triple-character syllables, 524 quadruple-character syllables and in total there are 5837 syllables. The findings in the experiments indicate that these syllables will turn up inconsistently across various language databases, but the most frequently occurring syllables are stably distributed while the non-frequent ones will differ in their level of presence, according to the size of database being referred to; and there is slight change in the frequency of the medium syllables. And statistical results that come up from the experiments seem to be contradictory to the number of theoretically normative Tibetan syllables available in Tibetan language, syllables in actual use only account for 39.2% of theoretically normative syllables. And syllables present in more than 90% of the texts only account for 12% of the syllables in actual use.
