The Dynamic Lexicon.

The dynamic lexicon is one of the central knowledge sources in SmarTkom that provides the whole system with the capabability to dynamically update the vocabulary. The corresponding multilingual pronunciations, which are needed by all speech-related components, are automatically generated. Furthermore, a novel approach for generating nonnative pronunciation variants and therefore for adapting the speech recognizer to nonnative accents is presented. The capability to deal with nonnative accents is crucial for dialogue systems dealing with multimedia and therefore often with multilingual content. [ABSTRACT FROM AUTHOR]
