Transliteration of Proper Names in Cross-Lingual Information Retrieval

We address the problem of transliterating English names using Chinese orthography in support of cross-lingual speech and text processing applications. We demonstrate the application of statistical machine translation techniques to "translate" the phonemic representation of an English name, obtained by using an automatic text-to-speech system, to a sequence of initials and finals, commonly used sub-word units of pronunciation for Chinese. We then use another statistical translation model to map the initial/final sequence to Chinese characters. We also present an evaluation of this module in retrieval of Mandarin spoken documents from the TDT corpus using English text queries.
