该文旨在实现从藏文文本到国际音标的自动转换,在一定程度上解决获取较大规模的藏文国际音标标注文本的问题。在国际音标转换系统中,采用了基于规则和统计融合的方法,实现了文语语音词自动切分;利用辅音、元音和声调对应规则表实现了藏语音节的国际音标自动转换;利用声调变化规则、辅音和元音变化规则实现了基于语音词的声调变调、辅音和元音的变化。从自动标注的结果来看,达到了实用效果。

This paper applies rules and statistical methods to realize conversion form Tibetan texts to IPA texts. The procedures of conversion include word segmentation , and construction of mapping rules and patterns of consonants, vowels, tones and monosyllables or multi-syllables. Experimental results show the proposed system does well in IPA conversion.
