Resumo(s)
In this paper we report on the acquisition and content of a new database
intended for developing audio-visual speech recognition systems. This database
supports a speaker dependent continuous speech recognition task, based on a small
vocabulary, and was captured in the European Portuguese language. Along with
the collected multi-modal speech materials, the respective orthographic transcription
and time-alignment files are supplied. The package also includes data on stochastic
language models and the generative grammar associated to the collected spoken
sentences. The application addressed by this database, which consists of voice control
of a basic scientific calculator, has the particularity of being designed for a person
with a specific motor impairment, namely muscular dystrophy. This specificity is a
remarkable characteristic, given the lack of such kind of data resources for developing
assistive systems based on audio-visual speech recognition technology.
