The methods rely on an iterative optimization algorithm. It was found that formant parameter data derived with these methods was less prone to discontinuity errors than conventional methods. Also, experiments were conducted that demonstrated that these methods are capable of better accuracy in formant estimation than LPC, especially for the first formant. In some cases, the analytic (non-iterative) solution has been derived, making real time applications feasible. The main target that we have been pursuing is text-to-speech (TTS) conversion. These methods are being used to automatically analyze a concatenation database, without the need for a tuning phase to fix errors. In addition, they are instrumental in realizing high quality pitch tracking, and pitch epoch marking.","PeriodicalId":117113,"journal":{"name":"5th International Conference on Spoken Language Processing (ICSLP 1998)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115309172","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}

It can select the model which is most similar to a target speaker. However, this method does not consider speaker difference dependent on phoneme class. In this paper, we propose a speaker adaptation method based on speaker clustering by taking speaker difference dependent on phoneme class into account. The experimental results showed that the new method gave a better performance than the original method. Furthermore, we propose the improved method which use a tree-structure of a similar phoneme as the substitute for the phoneme which does not appear in the adaptation data. From the experimental results, the improved method gave a better performance than the method previously proposed.","PeriodicalId":117113,"journal":{"name":"5th International Conference on Spoken Language Processing (ICSLP 1998)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115383236","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 transcription, however, is tedious and expensive. In this work we describe our experiments which are aimed at training a speech recognizer without transcriptions. The experiments were carried out with TV newscasts, that were recorded using a satellite receiver and a simple MPEG coding hardware. The newscasts were automatically segmented into segments of similar acoustic background condition. This material is inexpensive and can be made available in large quantities, but there are no transcriptions available. We develop a training scheme, where a recognizer is boot-strapped using very little transcribed data and is improved using new, untranscribed speech. We show that it is neces-sary to use a con(cid:12)dence measure to judge the initial transcriptions of the recognizer before using them. Higher im-provements can be achieved if the number of parameters in the system is increased when more data becomes available. We show, that the bene(cid:12)cial e(cid:11)ect of unsupervised training is not compensated by MLLR adaptation on the hypothesis. In a (cid:12)nal experiment, the e(cid:11)ect of untranscribed data is compared with the e(cid:11)ect of transcribed speech. Using the described methods, we found that the untranscribed data gives roughly one third of the improvement of the transcribed material.","PeriodicalId":117113,"journal":{"name":"5th International Conference on Spoken Language Processing (ICSLP 1998)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115497599","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 study raises a number of issues related to methodologies for analysing interactional (typically conversational) data. Most important is the issue of the applicability of statistical sampling methods which are independent of the interactional events occurring within the talk. It concludes with suggestions for a methodology that examines long term acoustic phenomena (eg long term fundamental frequency) and relates events at the micro acoustic level to interactional events within a conversation.","PeriodicalId":117113,"journal":{"name":"5th International Conference on Spoken Language Processing (ICSLP 1998)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116635938","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 paper, local constraints are captured via the usual n-gram approach, while global constraints are taken into account through the use of latent semantic analysis. Anintegrative formulation is derivedfor the combination of these two paradigms, resulting in an en-tirely data-driven, multi-span framework for large vocabulary speech recognition. Because of the inherent comple-mentarity in the two types of constraints, the performance of the integrated language model compares favorably with the corresponding n-gram performance.

Including the neutral tone, there are 5 tones in Mandarin and these tones are syllable-level phenomena. A direct acoustic manifestation of tone is the fundamental frequency (f0). We will report on the effect of f0 on the acoustic recognition accuracy of a Mandarin recognizer. In particular, we put f0, its first derivative (f0 ¢ ), and its second derivative (f0 ¢¢ ) in separate streams of the feature vector. Stream weights are adjusted to investigate the individual effects of f0, f0 ¢ , and f0 ¢¢ to recognition accuracy. Our results show that incorporating the f0 feature negatively impacted accuracy, whereas f0’ increased accuracy and f0’’ seemed to have no effect.","PeriodicalId":117113,"journal":{"name":"5th International Conference on Spoken Language Processing (ICSLP 1998)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127252872","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}

Initially, duration characteristics are used to classify syllables as accented or not. The accented syllables are then subclassified based on fundamental frequency, F0, values. Potential F0 intonation gestures are schematized by connected line segments within a window around a given syllable. The schematizations are found using spline-basis linear regression. The regression weights on F0 points are varied in order to discount segmental effects and F0 detection errors. Parameters based on the line segments are then used to perform the subclassification. This paper presents new results in recognizing L*, L+H*, and L+!H* accents. In addition, the models presented here perform comparably (80% overall, and 74% accent type recognition) to models which do not distinguish bitonal accents.","PeriodicalId":117113,"journal":{"name":"5th International Conference on Spoken Language Processing (ICSLP 1998)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127496978","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}
