Recent advances in SRI''S IraqComm™ Iraqi Arabic-English speech-to-speech translation system

摘要

We summarize recent progress on SRI's IraqCommtrade Iraqi Arabic-English two-way speech-to-speech translation system. In the past year we made substantial developments in our speech recognition and machine translation technology, leading to significant improvements in both accuracy and speed of the IraqComm system. On the 2008 NIST-evaluation dataset our twoway speech-to-text (S2T) system achieved 6% to 8% absolute improvement in BLEU in both directions, compared to our previous year system.
