Abstract

The development of speech processing technologies requires the use of audio and text corpus. Despite these resources have been researched during years for several languages, there is not enough research made for Brazilian Portuguese language. This article describes the progress of the initiative of corpus creation and validation for Brazilian Portuguese, using Hidden Markov Models (HMM) based acustic models and statistical language models for large vocabulary continuous speech recognition.
