To benchmark the corpus, which has been freely released recently, experiments on automatic recognition of continuous whispered speech were conducted. When training and test conditions are matched, the NAM microphone is found to be more robust against background noise than the close-talking microphone. In mismatched conditions (noisy data, models trained on clean speech), we found that Vector Taylor Series (VTS) compensation is particularly effective for the NAM signal.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131471966","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}

In order to discard the linguistic information effectively, in this paper, we employed the phoneme mean F-ratio method to investigate the different contributions of different frequency region from the point of view of Chinese phoneme, and apply it for speaker identification. It is found that the speaker individual information depending on the phonemes is distributed in different frequency regions of speech sound. Based on the contribution rate, we extracted the new features and combined with GMM model. The experiment for speaker identification task is conducted with a King-ASR Chinese database. Compared with the MFCC feature, the identification error rate with the proposed feature was reduced by 32.94%. The results confirmed that the efficiency of the phoneme mean F-ratio method for improving speaker recognition performance for Chinese.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121059385","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}

A new confidence measure, based on phoneme models trained on an Artificial Neural Network, is used in the verification stage to reduce false alarms. We have found that this ANN-based confidence, together with existing HMM-based confidence measures, is very effective in rejecting false alarms.

It focuses on finding sounds according to human perceptions. Thus such retrieval is more “human-centered” [1] than previous audio retrievals which intend to find homologous sounds. We make comprehensive use of various acoustic features to measure the perceptual similarity. Since some acoustic features may be redundant or even adverse to the similarity measurement, we propose to find a complementary and effective combination of acoustic features via SFFS (Sequential Floating Forward Selection) method. Experimental results show that LSP, MFCC, and PLP are the three most effective acoustic features. Moreover, the optimal combination of features can improve the accuracy of similarity classification by about 2% compared with the best performance of a single acoustic feature.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128652647","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}

However, to train HMMs of all possible contexts well is difficult, or even impossible, due to the intrinsic, insufficient training data coverage problem. As a result, thus trained models may over fit and their capability in predicting any unseen context in test is highly restricted. Recently cross-validation (CV) has been explored and applied to the decision tree-based clustering with the Maximum-Likelihood (ML) criterion and showed improved robustness in TTS synthesis. In this paper we generalize CV to decision tree clustering but with a different, Minimum Generation Error (MGE), criterion. Experimental results show that the generalization to MGE results in better TTS synthesis performance than that of the baseline systems.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129084301","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}

Simulation results show the proposed algorithm is effective in improving ASR rates in a sound field mixed with a directional interference and diffuse noise. Compared with the phase difference (PD) algorithm, the proposed method gives comparable recognition rates when facing a directional interference and much higher and more robust recognition rates when diffuse noise emerges.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127040670","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}

Fisher information distance is applied to compute distance between adjacent PDFs. Discriminant local preserving projection is used to push adjacent PDFs which belong to different classes apart to further improve the recognition accuracy.
