本文介绍了在第二次TC-STAR评估活动中开发的用于转录英语和西班牙语的欧洲议会全体会议（EPPS）的语音识别器。语音识别器是使用多个解码通道的最先进的系统，具有针对不同转录任务训练的模型（词典、声学模型、语言模型）。与LIMSI TC-STAR 2005 EPPS系统相比，2006年开发数据的相对字错误率降低了约30%。2006年EPPS评估数据的单词错误率与LIMSI系统是8.2%的英语和7.8%的西班牙语。还描述了跨站点适应和系统组合的实验。
This paper describes the speech recognizers developed to transcribe European Parliament Plenary Sessions (EPPS) in English and Spanish in the 2nd TC-STAR Evaluation Campaign. The speech recognizers are state-of-the-art systems using multiple decoding passes with models (lexicon, acoustic models, language models) trained for the different transcription tasks. Compared to the LIMSI TC-STAR 2005 EPPS systems, relative word error rate reductions of about 30% have been achieved on the 2006 development data. The word error rates with the LIMSI systems on the 2006 EPPS evaluation data are 8.2% for English and 7.8% for Spanish. Experiments with cross-site adaptation and system combination are also described.
