Title: Who owns Japanese language?[JP]

日本語は誰のものか? −日本語教育が育成すべき日本語能力と教師の役割を考える−

日本語教育が育成すべきなのはどのような日本語能力か。教師や教室はそのためにど のような役割を担えるか。本講演では、この問いについて言語とコミュニケーションの観 点から考える。「日本人みたいに話せるようになりたい」「日本人のように日本語が上手だ」といっ た発言を聞くことがある。もちろんこのような発言は,「日本語が上手になりたい」とい う思いや相手の日本語力を誉める気持ちから来ているのだろう。しかしながら、そこから は「日本人みたいな話し方」といったものが存在するという誤解が窺える。そこには日本 語の特徴が影響している可能性がある。この誤解を乗り越え次に進むためには、「社会と は何か」「そこに言語の使い手としての「私」がどう位置づけられるのか」を考える必要 がある。それらの議論を踏まえて、日本語教育が育成するべき日本語能力、日本語教師に求め られる文法教育力について述べるとともに、教育実践の事例を紹介したい。

Title: Perceptual and structural analysis of pronunciation diversity of World Englishes[EN]

English is the only language available for global communication but its form is altered easily and variously depending on the language background of speakers. If we take two users of English, their pronunciation will show different characteristics, called accents. Today, we often hear the term of World Englishes (WE), where it is claimed that there is no standard pronunciation of English. English is a very useful tool but it is true that, in international context, accents often cause miscommunications. In this talk, the lecturer will show recent results obtained in two on-going projects related to the diversity of pronunciation of WE.

In the first project, his research team objectively measured the intelligibility of Japanese accented English (JE) spoken to American listeners with almost no prior exposure to JE. 100 male and 100 female university students repeated reading given sentences until they thought they could read adequately. Their “adequate” readings were recorded and presented on a telephone line to American listeners who had seen Japanese only on television. The task was just to repeat what they heard and their responses were transcribed word by word. In this experiment, as reference, native utterances were also used and in total, 800 utterances of JE and 100 utterances of American English (AE) were presented to 173 American listeners. On average, one utterance was heard by 21 listeners. Word-based correct perception rates were 89.2% for AE but only 50.0% for JE. It should be noted that all the utterances used were “adequate” for the Japanese speakers. Using these data, we’re developing a technique that takes an English manuscript as input and displays which parts of the manuscript will be unintelligible to American listeners if it is read with a Japanese accent.

Do Japanese have to learn the American accent more or do Americans have to adapt themselves to the Japanese accent more? The lecturer considers that one should be more aware of how diverse WE pronunciation is and where his/her pronunciation is located in the diversity. Currently, we can find a good online resource of WE such as TED talk archive. In the second project, the lecturer’s team is developing a technology that can cluster WE pronunciations by the unit of individual, with which, a global but individual-basis pronunciation map of WE and an accent-based browser of TED talks will be possible. In the experiment, by using the Speech Accent Archive (SAA), the accent gap between any two SAA speakers was defined quantitatively by using their IPA transcripts. After that, the accent gaps were predicted automatically only by using speech signals of those speakers. Results showed that the correlation between IPA-based gaps and predicted gaps is 0.77, which is comparable to the correlation between IPA-based gaps and phoneme-based gaps. In the lecture, some future directions are also indicated.

Nobuaki Minematsu obtained the Doctor of Engineering degree from Graduate School of Engineering, the University of Tokyo in 1995 and is currently a full professor there. He has a very wide interest in speech communication covering from science to engineering. He has published more than 400 scientific and technical papers including conference papers. They are related to speech analysis, speech perception, speech recognition, speech synthesis, speech applications especially related to CALL, etc. He received paper awards from RISP, JSAI, ICIST, and O-COCOSDA in 2005, 2007, 2011, and 2014 and received an encouragement award from PSJ in 2014. Recently, he gave tutorial seminars on CALL at APSIPA2011 and INTERSPEECH2012 and more than fifty OJAD tutorial workshops all over the world. He also gave invited talks or keynote talks at ICIST2014, PAAL2014, and O-COCOSDA2014. From 2015, he is a distinguished lecturer of APSIPA. He is a member of IEEE, ISCA, IPA, SLaTE, APSIPA, IEICE, ASJ, etc.
