The idea of i-vectors is to represent the characteristics of speakers in the factors of a factor analyzer. Because the factor loading matrix defines the possible speaker and channel-variability of i-vectors, it is important to suppress the unwanted channel variability. Linear discriminant analysis (LDA), within-class covariance normalization (WCCN), and probabilistic LDA are commonly used for such purpose. These methods, however, require training data comprising many speakers each providing sufficient recording sessions for good performance. Performance will suffer when the number of speakers and/or number of sessions per speaker are too small. This paper compares four approaches to addressing this small sample-size problem: (1) preprocessing the i-vectors by PCA before applying LDA (PCA+LDA), (2) replacing the matrix inverse in LDA by pseudo-inverse, (3) applying multi-way LDA by exploiting the microphone and speaker labels of the training data, and (4) increasing the matrix rank in LDA by generating more i-vectors using utterance partitioning. Results based on NIST 2010 SRE suggests that utterance partitioning performs the best, followed by multi-way LDA and PCA+LDA.","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":"127683899","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}

Firstly, a set of texts are synthesized by the baseline unit selection synthesis system. Each prosodic word within the synthetic speech is then evaluated as a natural one or an unnatural one by listeners. In our proposed method, these natural synthetic segments are treated as virtual candidate units to extend the original speech corpus for unit selection. A new speech synthesis system is constructed using this extended speech corpus. A synthetic error detector based on SVM classifier is also built using the natural and unnatural synthetic speech. At synthesis time, the input text is synthesized using the baseline system and the extended system simultaneously. The two unit selection results are evaluated by the trained synthetic error detector to determine the optimal one. Experimental results prove the effectiveness of our proposed method in improving the naturalness of synthetic speech on a task of synthesizing place names.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"69 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":"130753248","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 two experiments, we examined the listeners' use of pitch height and the position of turning point as cues of tone identity. The result showed that, in isolated syllables, Chinese perceived these two tones in categorical fashion. Pitch height was more important than the turning point as a cue. Within a certain range of pitch height, there was a complementary relationship between these two variables. The perceptual result of Japanese subjects did not show apparent categorical pattern. In disyllables, for Chinese subjects, the contextual influence on the boundary position in Tone 2-half Tone 3 continuum was not significant, but the boundary position in pitch height and turning point Tone 2-Tone 3 continuum shifted significantly in different tonal context. Comparing to Chinese subjects, Japanese subjects' perceptual ranges of Tone 3 in isolated syllables and disyllables were narrower, and it's more difficult for them to identify these two tones in disyllables.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"57 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":"133378858","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, no research so far has examined the effect of the listeners' exposure and training in a second language (L2) on their understanding of L2-accented native language (L1). This paper aims to address this issue with subjects whose L1 is English, L2 is Mandarin. Characteristics of Mandarin-accented English include the devoicing of word-final consonants, and the insufficient distinction of the vowel pairs /i:/ - /i/ and /ε/ - /æ/. These features could negatively affect listeners' understanding of contrastive word pairs. In this study, 9 native Mandarin listeners, 9 monolingual English listeners and 9 English-Mandarin bilinguals were asked to listen to recordings of Mandarin-accented English and identify minimal pairs involving the above consonant and vowel contrasts. Results show that among all three groups of subjects, native Mandarin listeners scored the highest accuracy, but English listeners with training in Mandarin and monolingual English speakers had similar scores. These findings support the existence of ISIB for Mandarin, and call for further study on bilingual L2 learners.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"2 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":"127199293","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 this framework, a hierarchical prosodic unit based on Fujisaki model is used to take local pitch contour variation and global intonation of utterance into account. Furthermore, novel ways of integrating pitch contour pattern of prosodic units in the prosodic model are invents in order to improve the selection mechanism of the appropriate pitch contour. A novel prosodic unit selection method is proposed based on sentence retrieval, which not only uses the traditional linguistic cue as selection criterion, but also the shape of the pitch contour. Also, the codewords of pitch patterns in the training corpus and synthesized corpus were constructed by the proposed method and were used to map the relation between training codeword and synthesized corpus. Finally, the language model of pitch pattern is adopted to find the proper pitch pattern sequence of input text. The evaluation results demonstrate that the proposed prosodic model substantially improves naturalness of the intonation of the synthesized speech compared to that of model-based method.","PeriodicalId":186099,"journal":{"name":"2012 8th International Symposium on Chinese Spoken Language Processing","volume":"17 6 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":"125733164","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}
