The LIUM-AVS Database : A Corpus to Test Lip Segmentation and Speechreading Systems in Natural Conditions

Philippe Daubias, Paul Deleglise

Universite du Maine, France

We present here a new freely available audio-visual speech database. Contrary to other existing corpora, the LIUM-AVS corpus was recorded in conditions we qualify as natural, which are, according to us, much closer to real application conditions than other databases. This database was recorded without artificial lighting using an analog camcorder in camera mode. Images were stored digitally with no compression to keep the highest possible image quality. The LIUM-AVS database comprises two parts: (*) series PBS Phonetically Balanced Sentences in French (*) series LET Spelled letters (also in French) These two parts contain sequences with both natural and blue lips. The whole database is released mainly to test and compare lip segmentation approaches on natural images, but speech recognition experiments may also be carried using this corpus. For information on obtaining the LIUM-AVS database, please contact us through our webpage (http://www-lium.univlemans. fr/lium/avs-database).
