In this paper, we describe the work of the LUPo (Portuguese Unisyn Lexicon) project to model standard and non-standard varieties of spoken Portuguese from around the globe, and: (1) deliver a free, open-source tool for the automatic generation of accent-specific pronunciation lexica within the existing online lexical knowledge base, the Portal da Lingua Portuguesa; and (2) provide the research and speech technology communities with a free, online, searchable database, the Portuguese RADbank, dedicated to the description of regional varieties of spoken Portuguese.
