This chapter provides a computational analysis of the variation in the pronunciation of some Tibetan numbers. In Tibetan, the names for numbers greater than ten are formed by concatenating the word for a number less than ten with the word that means ‘ten.’ We refer to these combinations as “compound numerals.” In particular, numbers from eleven to nineteen are formed by prefixing [ > dZu] ‘ten’...
