Creation and Validation of Large Lexica for Speech-to-Speech Translation Purposes

This paper presents specifications and requirements for creation and validation o f large lexica that are needed in automatic Speech Recognition (ASR), Text-to-Speech (TTS) and statistical Speech-to-Speech Translation (SST) systems . The prepared language resources are created and validated within the scope o f the EU-project LC-STAR (Lexica and Corpora for Speech-toSpeech Translation Components) during years 2002-2005 . Large lexica consisting o f phonetic, suprasegmental and morphosyntactic content will be provided with well-documented specifications for 13 languages . A short summary o f the LC-STAR project itself is presented . Overview about the specification for the corpora collection and word extraction as well as the specification and format o f the lexica are presented . Particular attention is paid to the validation o f the produced lexica and the lessons learnt during pre-validation . The created and validated language resources will be available via ELRA/ELDA .
