This paper introduces several important features of the Chinese large vocabulary continuous speech recognition system in the NICT/ATR multi-lingual speech-to-speech translation system. The features include：（1） a flexible way to derive an information rich phoneme set based on mutual information between a text corpus and its phoneme set; （2） a hidden Markov network acoustic model and a successive state splitting algorithm to generate its model topology based on a minimum description length criterion; and （3） advanced language modeling using multi-class composite N-grams. These features allow a recognition performance of 90% character accuracy in tourism related dialogue with a real time response speed.

This paper describes the latest version of the Chinese-Japanese-English handheld speech-tospeech translation system developed by NICT/ATR, which is now ready to be deployed for travelers. With the entire speech-to-speech translation function being implemented into one terminal, it realizes real-time, location-free speech-to-speech translation. A new noise-suppression technique notably improves the speech recognition performance. Corpus-based approaches of speech recognition, machine translation, and speech synthesis enable coverage of a wide variety of topics and portability to other languages. Test results show that the character accuracy of speech recognition is 82%-94% for Chinese speech, with a bilingual evaluation understudy score of machine translation is 0.55-0.74 for Chinese-Japanese and Chinese-English

Corpus-based Speech-to-speech Translation in Travel Domain

第十三届全国人机语音通讯学术会议(NCMMSC2015)

作者： satoshi nakamura Nara Institute of Science and Technology

Spoken language technologies enable to support natural oral communication. Language barrier between different language speaking people is one of the biggest communication problems for human being. Speech-to-speech translation had been studied in order to break the language barrier. In this talk, I would like to introduce brief history of the speech-to-speech translation research and state-of-the-art speech translation system. Then I would introduce new challenges toward a simultaneous speech-to-speech translation including simultaneous incremental machine translation, joint-optimization of ASR and MT modules, Speech-to-speech translation preserving para/non-linguistic information and multimodal speech translation with a talking face. Finally I would introduce various spoken dialog research activities to overcome human-machine language barriers.

Corpus-based Speech-to-speech Translation in Travel Domain

Correlation of the nuclear accumulation of CTNNB1 and colonic tumorigenesis

第九届全国人机语音通讯学术会议

作者： satoshi nakamura

We describe a multi-lingual speech-to-speech translation （S2ST） system, which is mainly focused on translation between English and Asian languages （Japanese and Chinese）. There are three main modules of our S2ST system: large vocabulary continuous speech recognition, machine text-to-text （T2T） translation, and text-to-speech synthesis. All of them are multilingual and are designed using state-of-the-art technologies. A corpus-based statistical machine learning framework forms the basis of our system. We use a parallel multilingual database consisting of over 1,000,000 sentences that cover a broad range of travel-related conversations. Recent evaluation of the overall system showed that speech-to-speech translation quality is high, being at the level of a person having a TOEIC score of 650 out of the perfect score of 990. Additionally, field experiment results in real various places will be introduced

CTNNB1 （or beta-catenin） is regarded as a central effecter in molecules of the wingless/Wnt signalling pathway, It is cadherin mediated cell to forms a complex with a key component of the cell adhesion system and the protein product of adenomatous polyposis coil （APC）, glycogen synthase kinase 3β （GSK3β） and conductin. One mutation of APC is also responsible for activation of wingless/Wnt signalling pathway and accumulation of free beta-catenin in the cell. Beta-catenin upregulates oncogenes, such as cyclin D1 and c-myc. Beta-catenin expression in cytoplasm and nuclei was reported to increase in many cases of intestinal tumorigenesis. In addition, the hyperexpression of integrin linked kinase （ILK） in colonic polyposis has been demonstrated.

To know the relation between NaCl concentration and hydrogen sulfide (H2S) production by MY Phenomenon of Salmonella, we developed a method to control H2S production by Salmonella in this study. Desoxycholate-hydrogen sulfide-lactose (DHL) agar was used as the selective medium for Salmonella. Triple sugar iron (TSI) agar was used as the screening medium. Citric acid disks were placed on DHL agar. NaCl was added to both media. After 24 hours incubation, H2S production on DHL agar was stimulated by citric acid, whereas production was suppressed by adding NaCl. The color change in the bottom of the TSI medium was due to the low production of black FeS. The production of FeS was reduced by lower H2S production by Salmonella with an increasing concentration of NaCl from 0.5% to 3%. The inhibition of the black color meant that the color change due to glucose fermentation could be seen clearly in the bottom of the agar. The current method cannot detect glucose fermentation but the addition of more NaCl to the TSI medium allowed the visualization of glucose fermentation by Salmonella. Although H2S production of salmonella was promoted by citrate etc., being controlled by sodium chloride was proved in this study. Thus, we had developed a possibility of novel technique for the detection of Salmonella etc.

Background: The symbiotic relationship between E. coli and Salmonella was demonstrated using hydrogen sulfide production named MY phenomenon, which is a feature of Salmonella. Methods: In order to confirm the hydrogen sulfide production of Salmonella by iron sulfide formation, deoxycholate-hydrogen sulfate-lactose agar medium having both a sulfur source and an iron source was used. The case where Salmonella was cultured alone was compared with the case co-cultured with E. coli. In the case of culture with Salmonella alone, the MY phenomenon has not occurred. When Salmonella was co-cultured with E. coli, Salmonella cultured near E. coli existing place showed a black color named MY phenomenon. When E. coli was cultured alone, it turned red due to the organic acid produced. However, when E. coli was cultured in the part where Salmonella. is inoculated on the surface of the medium, the MY phenomenon appeared there. Furthermore, hydrogen sulfide production was more active in Salmonella co-existing with E. coli. Conclusion: The study shows an important relation that E. coli is a promoting factor for Salmonella culture by NY phenomenon. The relation suggests that bacterial symbiosis relation exist in bacterial flora.
