An audio-visual corpus for speech perception and automatic speech recognition (L)

An audio-visual corpus has been collected to support the use of common material in speech perception and automatic speech recognition studies. The corpus consists of high-quality audio and video recordings of 1000 sentences spoken by each of 34 talkers. Sentences are simple, syntactically identical phrases such as "place green at B 4 now." Intelligibility tests using the audio signals suggest that the-material is easily identifiable in quiet and low levels of stationary noise. The annotated corpus is available on the web for research use. (c) 2006 Acoustical Society of America.
