Abstract
Despite the availability of several speech corpora that can be used to build automatic speech recognition systems, there are only a few corpora for the Brazilian Portuguese (BP) language. This lack of corpora does not allow an extensive and deep research on continuous speech recognition systems for BP. In this work, we present a baseline system for continuous speech recognition for BP and its results using the West Point Brazilian Portuguese Corpus. In addition to the results, the resources developed to build the system are made available for continuing the research on such systems for BP.
