This study proposed and evaluated an audio-visual teaching aid for teaching rhythm of spoken English. The teaching aid instructs stress timing of English by movements of a circle marker on PC screen. Native Japanese participants exercised English sentences with and without the teaching aid and their speech sounds were recorded before and after the exercise. The results of analyses of the speech sounds showed that the teaching aid could improve in learning the English stress timing.

This study attempted to improve the five-degrees-of-freedom sensors of the Northern Digital Incorporated's Wave electromagnetic articulography system by replacing their cables with thinner and more flexible cables to reduce interference in articulation. Measurement errors and data loss rates were compared between the original and the proposed sensors. The proposed sensors showed twofold tracking accuracy and data loss rates compared to the original sensors in an experiment using a crank-rocker mechanism. Data loss rates of the proposed sensors increased in articulatory data collection from four speakers. The proposed sensors have been made available commercially.

This paper describes a manzai robot system with scalability that is developed based on the distributed software components. Manzai is a Japanese traditional stand-up comedy that is usually performed by two comedians. The manzai robots generate their manzai scripts based on web news articles related to keywords given by audiences and the searching results on WWW automatically, and then the robots perform the manzai scripts. Each robot is controlled by distributed RT components executed on the Raspberry Pi controller. The RT components control the manzai robots synchronously. The paper focuses on the scalability of the manzai robot system. Experimental results show the feasibility of manzai performance robots with scalability of the functions of the robot systems.

Numerous studies have examined communication robots that communicate with people, but it is difficult for robots to communicate with people smoothly. We call the communication style based on dialogue between robots as "human-robot implicit communication". As described herein, we propose a Manzai-robots for which the interaction style is human-robot implicit communication based on an automatically generated scenario from web news. Our generated Manzai scenario consists of snappy patter and a misunderstanding of dialogue based on the four kinds of gap of structure of funny points. Our purpose is that people feel familiarity from smoothly human-robot communication using dialogue between robots based on a Manzai scenario. We conducted experiment of three kinds to assess (1) the effectiveness of automatic creation of Manzai scenario for the robots, (2) the effectiveness of the Manzai-robots as a media, and (3) the effectiveness of types of familiarity for Manzai-robots. Based on their results, we measured the familiarity and smooth communication of our Manzai-robots.

Today there is much information and knowledge on the internet, and many studies have examined the extraction of many kinds of knowledge from the internet. In addition, numerous studies have examined entertainment robots that communicate with people, but it is difficult for robots to communicate smoothly with people. We specifically examine communication between robots based on dialogue. Here, we create a dialogue-based scenario for the robots to undertake automatically, but it is difficult because the dialogue requires knowledge of many kinds. We consider the use of the knowledge from the web and create scenarios automatically. As described herein, we propose a system that generates dialogue scenarios automatically from web news articles in real time. We used the Manzai metaphor, which is Japanese traditional humorous comedy in our system. Our generated Manzai scenario consists of snappy patter and a misunderstanding dialogue based on the gap of our structure of funny points. We create communication robots to amuse people with our generated humorous robot dialogue scenarios.

Tongue Movement of Healthy Adults who Feel Clumsy Articulating Alveolar Flaps

Tongue movement of healthy young adults who feel clumsy articulating alveolar sounds in daily conversation was measured using the WAVE speech research system. Tongue blade movements of these speakers during repetitive production of Japanese /ra/ showed reduction of speed and movement range compared with those who feel no clumsiness, despite the absence of any organic or neurological abnormalities. Such differences may suggest underlying differences of fine and rapid motor controls required for smooth speech production which may be related to their awareness of clumsiness in articulation.

Crucial Prosodic Features in Japanese Learners' Pronunciation: Evidence from Naturalness Judgments of Synthetic Speech Reviewed

The present study reports native speakers' impressions of JFL learners' utterances before and after shadowing/repeating training. Evaluation was also done for prosodically modified synthesized stimuli in order to examine the crucial prosodic cues. The results suggest that both durational patterns and pitch patterns are important for the utterances to be heard as natural Japanese, but durational patterns may be more important. Moreover, shadowing training appears to improve mora-timed rhythm. The results of the present study could provide useful suggestions for developing pronunciation training for Japanese pronunciation and speech education.

Non-contact measurement of facial surface vibration patterns during singing by scanning laser Doppler vibrometer

This paper presents a method of measuring the vibration patterns on facial surfaces by using a scanning laser Doppler vibrometer (LDV). The surfaces of the face, neck, and body vibrate during phonation and, according to Titze (2001), these vibrations occur when aerodynamic energy is efficiently converted into acoustic energy at the glottis. A vocalist's vibration velocity patterns may therefore indicate his or her phonatory status or singing skills. LDVs enable laser-based non-contact measurement of the vibration velocity and displacement of a certain point on a vibrating object, and scanning LDVs permit multipoint measurements. The benefits of scanning LDVs originate from the facts that they do not affect the vibrations of measured objects and that they can rapidly measure the vibration patterns across planes. A case study is presented herein to demonstrate the method of measuring vibration velocity patterns with a scanning LDV. The objective of the experiment was to measure the vibration velocity differences between the modal and falsetto registers while three professional soprano singers sang sustained vowels at four pitch frequencies. The results suggest that there is a possibility that pitch frequency are correlated with vibration velocity. However, further investigations are necessary to clarify the relationships between vibration velocity patterns and phonation status and singing skills.
