PELECAN is created primarily for collecting pronunciation errors from Thai learners of English in order to develop a more suitable pronunciation assessment tool for Thais. A 2-phase data collection process is used to balance between recording effort and the coverage of interested acoustic phenomena. The data collected from the first phase contains 1.5 hours of speech from 30 Thai learners reading 2 English passages that cover all English phones. Recorded speech was annotated with 2 types of error annotation: phonetic transcription of incorrect pronunciation and level of correctness of each phone. A contrastive list was used to guide the error analysis process. We found that many pronunciation errors are influenced by L1 (Thai), e.g. incorrect pronunciations of suffixes and the deletion of /l/ and /r/ in consonant clusters. However, there are some errors that may not be predictable from contrastive analysis alone such as the case of schwa. Hence, the data driven approach could help identify errors that may not be foreseen from only a linguistic point of view.","PeriodicalId":269402,"journal":{"name":"2011 International Conference on Speech Database and Assessments (Oriental COCOSDA)","volume":"1905 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133121719","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}

Meaning of a speech sample changes when it is uttered with different emotions. The present paper gives a description of different types of studies conducted to analyze, perceive and recognize commonly occurring emotions in Hindi speech. These have been classified as anger, happiness, fear, sadness, surprise in addition to neutral. Intonation, intensity and duration patterns changes due to changes in sentence types as well as due to changes in emotions. A relationship among the measured acoustic parameters and the patterns has been used to classify them. Experiments have been conducted to study and recognise emotions based on phonetic as well as prosodic parameters in the speech samples due to changes in emotions. These parameters include MFCC & their derivatives and prosodic parameters as the F0, A0 and Duration. In one of the experiment vowel segments taken from continuously spoken sentences and in another experiment Hindi digits were used as speech samples for machine recognition of emotions using the Neural Net classifiers. Human perception experiments have been conducted at all levels of experiments and compared the results with machine recognition performance. In most cases it has been found that machine recognition was found to be better compared to human performance. Both Phonetic as well as prosodic parameters play role in identification of emotions.","PeriodicalId":269402,"journal":{"name":"2011 International Conference on Speech Database and Assessments (Oriental COCOSDA)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124673006","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}

Our scheme consists of two-stage annotation, in which RTs are first identified and classified according to their forms and then further sub-classified based on their sequential positions. Six forms are included in our class of RTs: i) responsive interjections, ii) expressive interjections, iii) lexical reactive expressions, iv) repetitions, v) completions, and vi) assessments. Some of them bear an additional tag according to their sequential position in the discourse: i) first pair parts, ii) second pair parts, iii) sequence-closing thirds, iv) other responding turns, and v) unclassifiable positions. We apply our scheme to annotate a Japanese three-party conversation corpus, and present the results of a preliminary analysis on the distribution of RTs in the corpus.","PeriodicalId":269402,"journal":{"name":"2011 International Conference on Speech Database and Assessments (Oriental COCOSDA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128476955","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 systems first select a question example which is the most similar to the recognition result for the input voice from the database. An answer sentence which is then paired with the selected question example is output to the user. Many systems have a large database to enable a more appropriate answer to be output. However, when such a database is used, the waiting time increases because the system needs to find the most appropriate question example from a vast number of question examples. We propose a method of classifying the queries in the QADB. By classifying question examples into some clusters using pLSA, an appropriate question example can be found more quickly than when using the conventional method. We evaluated the validity of our proposed method by changing various parameters.","PeriodicalId":269402,"journal":{"name":"2011 International Conference on Speech Database and Assessments (Oriental COCOSDA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126715513","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}

We have found following facts regarding Uigur vowels: vowel acoustic space is closely related with duration, which is affected by syllabic position, number and type. For vowel in word-initial CV and V syllable, vowel duration is decreased with increasing of number of syllable. But, the difference of vowel duration between monosyllabic and disyllabic words is huge, reaching 2–4 times in most cases. In addition, vowel /ε/, /o/ have longer durations and /i/, /u/ (high vowels) have shorter durations. Vowel /u/ has wider variance of duration.","PeriodicalId":269402,"journal":{"name":"2011 International Conference on Speech Database and Assessments (Oriental COCOSDA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115865278","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}

Acoustic segment models (ASMs) are a set of hidden Markov models (HMM) that are obtained in an unsupervised manner without using any transcription information. The training of ASMs follows an iterative procedure, which consists of the steps of initial segmentation, segments labeling, and HMM parameter estimation. The ASMs are incorporated into a template-matching framework for query-by-example STD. Both the spoken query examples and the test utterances are represented by frame-level ASM posteriorgrams. Segmental dynamic time warping (DTW) is applied to match the query with the test utterance and locate the possible occurrences. The performance of the proposed approach is evaluated with different DTW local distance measures on the TIMIT and the Fisher Corpora respectively. Experimental results show that the use of ASM posteriorgrams leads to consistently better performance of detection than the conventional GMM posteriorgrams.","PeriodicalId":269402,"journal":{"name":"2011 International Conference on Speech Database and Assessments (Oriental COCOSDA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128461605","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}
