AUDIMUS.MEDIA: A Broadcast News Speech Recognition System for the European Portuguese Language

摘要

Many applications such as media monitoring are experiencing a large expansion as a consequence of the different emerging media sources and can benefit dramatically by using automatic transcription of audio data. In this paper, we describe the development of a speech recognition engine, AUDIMUS.MEDIA used in the Broadcast News domain. Additionally we describe recent improvements that permitted a relative recognition error decrease of more than 20% and a 4x speed-up.
