Abstract
This paper shows that web pronunciations such as those available in the Wiktionary can be used efficiently for building a pronunciation lexicon for a speech transcription system. The pronunciations of words and expressions extracted from the Wiktionary provided data that were used either directly or for training data-driven grapheme-to-phoneme conversion systems, in order to make possible the development of pronunciation lexicons. As an example, French Wiktionary pronunciations were extracted. The derived pronunciations lexicons were then used for training the acoustic models and for evaluating speech recognition performance on the French broadcast news data from the ESTER2 campaign. Moreover, the results show that combining the pronunciations delivered by two different grapheme-to-phoneme conversion systems yields significant performance improvement.

paper shows that web pronunciations such as those available in the Wiktionary can be used efficiently for building a pronunciation lexicon for a speech transcription system. The pronunciations of words and expressions extracted from the Wiktionary provided data that were used either directly or for training data-driven grapheme-to-phoneme conversion systems, in order to make possible the development of pronunciation lexicons. As an example, French Wiktionary pronunciations were extracted. The derived pronunciations lexicons were then used for training the acoustic models and for evaluating speech recognition performance on the French broadcast news data from the ESTER2 campaign. Moreover, the results show that combining the pronunciations delivered by two different grapheme-to-phoneme conversion systems yields significant performance improvement.</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Nancy</li></settlement><orgName><li>Institut national polytechnique de Lorraine</li><li>Université Nancy 2</li><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Jouvet, Denis" sort="Jouvet, Denis" uniqKey="Jouvet D" first="Denis" last="Jouvet">Denis Jouvet</name></region><name sortKey="Fohr, Dominique" sort="Fohr, Dominique" uniqKey="Fohr D" first="Dominique" last="Fohr">Dominique Fohr</name><name sortKey="Illina, Irina" sort="Illina, Irina" uniqKey="Illina I" first="Irina" last="Illina">Irina Illina</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
