1. A system for generating base forms for non-native language in a speech-based system trained for processing a native language, the system comprising:

  • a text processing system configured to receive input textual data containing both native language and non-native language words, the text processing system configured to identify the native language and non-native language words within the textual data, to generate a native phonetic transcription of the native language word using phonetic units of the native language, and to generate a non-native phonetic transcription of the non-native language word using phonetic units of the non-native language;

    a pronunciation generator configured to generate a native pronunciation of the non-native language word using phonetic units of the native language by mapping the phonetic units of the non-native phonetic transcription to acoustically similar phonetic units of the native language; and

    a memory configured to store the input textual data with the corresponding native phonetic transcription of the native language word and the mapped native pronunciation of the non-native language word in a native phonetic lexicon.
