Posterior-based out of vocabulary word detection in telephone speech

Stefan Kombrink, Lukáš Burget, Pavel Matějka, Martin Karafiát, Hynek Hermansky

In this paper we present an out-of-vocabulary word detector suitable for English conversational and read speech. We use an approach based on phone posteriors created by a Large Vocabulary Continuous Speech Recognition system and an additional phone recognizer, that allows detection of OOV and misrecognized words. In addition, the recognized word output can be transcribed more detailed using several classes. Reported results are on CallHome English and Wall Street Journal data.
