Acoustic Phonetic Decoding Oriented to Multilingual Speech Recognition in the Basque Context

The development of Large Vocabulary Continuous Speech Recognition systems involves issues as: Acoustic Phonetic Decoding, Language Modelling or the development of appropriated Language Resources. In the state of the art, new techniques for reusing Language Resources of more resourced related languages is becoming of great interest, and there is also a growing interest on Multilingual systems. This paper describes the initial experiments on multilingual recognition and cross-lingual adaptation carried out in order to create a robust Multilingual Speech Recognition system for the Basque context. The interest on Multilingual Systems arouses because there are three official languages in the Basque Country (Basque, Spanish, and French), and there is much linguistic interaction among them, even if Basque has very different roots than the other two languages.
