Language and variety verification on broadcast news for Portuguese

This paper describes a language/accent verification system for Portuguese, that explores different type of properties: acoustic, phonotactic and prosodic. The two-stage system is designed to be used as a pre-processing module for the Portuguese Automatic Speech Recognition (ASR) system developed at INESC-ID. As the ASR system is applied everyday to transcribe the evening news from a Portuguese public TV channel, the presence of other languages (mainly English) and other varieties of Portuguese is very likely. In the first stage, for each automatically detected speaker, the system verifies if the spoken language is Portuguese, as opposed to nine other languages
