The previous work on word alignment mainly focuses on the training process to get the word mapping relation between the source sentences and target sentences. However, the word alignment for combination of SMT system outputs is also important, which aims to find the word correspondence between alternative translation hypotheses of a source language sentence. Unfortunately, it does not attract so much attention in SMT research. In this paper, we propose a novel word alignment approach to effectively address the word alignment between sentences with different valid word orders, which changes the order of the word sequences (called word reordering) of the output hypotheses to make the word order more exactly match the alignment reference. We present experimental results on the IWSLT'2008 challenge tasks with the combination of four state-of-the-art SMT systems outputs. The results show that our approach significantly improves the performance of the system combination.","PeriodicalId":291958,"journal":{"name":"2008 6th International Symposium on Chinese Spoken Language Processing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133712499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transform orders for FrFT are adaptively set according to the intraframe pitch change rate. This method is motivated by the fact that the speech is not stationary even in a short period of time, and the idea is shown using an AM-FM speech model and some spectrograms of an artificial periodic signal. Experiments were conducted on the intervocalic English consonants provided by Interspeech 2008 Consonant Challenge and a Mandarin connected digits corpus. The performance of the proposed method is compared with the MFCC baseline system. Experimental results show that the proposed features get a slightly better recognition rate than MFCCs presumably because they can better track the dynamic characteristics of the speech harmonics.","PeriodicalId":291958,"journal":{"name":"2008 6th International Symposium on Chinese Spoken Language Processing","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133521453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The syllable FO contour model considers three major affecting factors, including lexical tone, syllable position in a word and inter-syllable coarticulation effect; while both the duration and energy models additionally consider one more affecting factor of base syllable type. Experimental results on a large single-speaker database showed that the method performed very well. Based on the prosodic model, a learning system for Mandarin word prosody pronunciation is designed and implemented for normative speakers.","PeriodicalId":291958,"journal":{"name":"2008 6th International Symposium on Chinese Spoken Language Processing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125092058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RESW establishes multiple eigen-MLLR subspaces as the set of a priori knowledge according to certain affecting factors, such as noise type, SNR, male and female. It then projects an input test utterance simultaneously into the set of eigen-subspaces and optimally synthesizes out a set of suitable HMMs. The proposed RESW was evaluated on Aurora 2 multi- condition training task. Experimental results showed that average word error rate (WER) of 6.11% was achieved. RESW not only outperformed the multi-condition training baseline (Multi-Con., 13.72%) but also the blind ETSI advanced DSR front-end (ETSI-Adv., 8.65%) and the histogram equalization (HEQ, 8.66%) and the non-blind reference model weighting (RMW, 7.29%) and Eigen-MLLR (6.14%) approaches.","PeriodicalId":291958,"journal":{"name":"2008 6th International Symposium on Chinese Spoken Language Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125878491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, there are two kinds of statistical representation for token sequences, N-gram language model (PR-LM) and support vector machines (PR- SVM) to perform language classification. In this paper we focus on PR-SVM method. One problem of the PR-SVM is that the statistical representation based on utterance is sparse and inaccurate. To tackle this issue, the adaptation schemes in PR-SVM framework are proposed in this paper. There are two schemes to be used: 1) Adaptation from the Universal N-gram Language Model (UNLM) trained on all languages; 2) Adaptation from the Low-Order N-gram Language Model (LONLM). The experimental results on 2007 NIST LRE tasks show that our method achieves significant gains over the unadapted model.","PeriodicalId":291958,"journal":{"name":"2008 6th International Symposium on Chinese Spoken Language Processing","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123172380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
