The authors are currently engaged in a project to introduce an automatic speech recognizer over PSTN. They have developed a voice-activated telephone exchange system by combining a continuous speech recognizer and a private branch exchange system (PBX), and conducted field trials. The system has been installed in the R&D laboratories for daily use since June 1993, in order to investigate its performance in a real environment and collect man-machine dialogues. More than 5,000 man-machine dialogues have been collected, and incorrect recognitions have been analyzed and categorized into three categories such as (1) incorrect detection of speech, (2) out-of-vocabulary responses, (3) incorrect recognition with inadequate hidden Markov models of speech and noise. The authors have improved system performance by mainly attacking the issues (1) and (3). They have just developed a new version of the system, using the improved scheme obtained by analyzing the collected speech data. In order to collect more man-machine dialogues, they are planning to carry out the second phase field trial in which the new system will be installed in branch offices.<<ETX>>","PeriodicalId":435907,"journal":{"name":"Proceedings of 2nd IEEE Workshop on Interactive Voice Technology for Telecommunications Applications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122525430","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}

Complementing the collection system, the data analysis system provides the capability to study, analyze and classify the collected data, to display and listen to collected utterances, generate statistics and enter analysis results in a database. A graphical user interface enhances the analysis system providing easy access to the database, and simplifying the analysis process. Methods used in measuring field recognition performance are presented, along with field results.

They then compare the performances of two types of triphone model based speaker independent recognition systems, in which they used the corpus for training models and testing. One system uses a normal continuous mixture density HMM, and the other uses a CDHMM with a tree structure of 2,064 Gaussian distributions, which needs only one thirtieth of the Gaussian computation of a normal one. As a result, the system with the tree-structure CDHMM performed as well as 3% less than the system using the normal CDHMM. This shows that tree-structure CDHMM are useful for telephone speech recognition.<<ETX>>","PeriodicalId":435907,"journal":{"name":"Proceedings of 2nd IEEE Workshop on Interactive Voice Technology for Telecommunications Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124143892","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 paper is concerned with NYNEX's development of interactive speech and language systems for the provision of automated information services. While the long-term goal is to develop total system solutions to interact with users and assist them to search and retrieve information, progress is made in such a way that each component technology can be deployed by itself in various telecommunications applications. The authors discuss some of their findings, and draw from experience in technology development, lessons that have been learnt from service trials, and benefits that have been derived from others in the research community. The authors believe that advanced speech and language technologies can be quite acceptable to users, as long as a graceful and friendly human computer interface is also provided.<<ETX>>","PeriodicalId":435907,"journal":{"name":"Proceedings of 2nd IEEE Workshop on Interactive Voice Technology for Telecommunications Applications","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131481533","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 get the highest possible performance of the speech recognizer a number of commonly used feature extraction methods (MFCC, LPC, PLP, RASTA-PLP) and classification methods (MLP, LVQ, HMM) were tested on the same telephone speech data. All combinations of feature extraction and classification methods were computed and several parameters of both methods where changed in order to find a non-local maximum of recognition accuracy. The paper does not describe a comparison of classification but of feature extraction methods because it is clear that an HMM would outperform both LVQ and MLP. The big question is if the same feature extraction methods always lead to the best results, no matter which classifier is used!.<<ETX>>","PeriodicalId":435907,"journal":{"name":"Proceedings of 2nd IEEE Workshop on Interactive Voice Technology for Telecommunications Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131640213","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}

Several technologies will play major roles in this communications revolution, but one of the key ones will be voice processing. The authors review several voice processing technologies, discuss current capabilities and the associated applications, and try to forecast where they see progress being achieved in the next decade and what applications will become commonplace as a result of the increased capabilities. They show how progress in voice processing is accompanied and stimulated by progress in microelectronics (memory and processing power of single chip architectures), and how, by the 21st century, telecommunications will have made major advances as a result of the use of voice processing.<<ETX>>","PeriodicalId":435907,"journal":{"name":"Proceedings of 2nd IEEE Workshop on Interactive Voice Technology for Telecommunications Applications","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132334819","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}
