Statistical Machine Translation of Broadcast News from Spanish to Portuguese

  • Conference paper
Computational Processing of the Portuguese Language (PROPOR 2008)

Abstract

In this paper we describe the work carried out to develop an automatic system for translation of broadcast news from Spanish to Portuguese. Two challenging topics of speech and language processing were involved: Automatic Speech Recognition (ASR) of the Spanish News and Statistical Machine Translation (SMT) of the results to the Portuguese language. ASR of broadcast news is based on the AUDIMUS.MEDIA system, a hybrid ANN/HMM system with multiple stream decoding. A 22.08% Word Error Rate (WER) was achieved in a Spanish Broadcast News task, which is comparable to other international state of the art systems. Parallel normalized texts from European Parliament database were used to train the SMT system from Spanish to Portuguese. Preliminary non-exhaustive human evaluation showed a fluency of 3.74 and sufficiency of 4.23.
