This article will present the methodology, as well as the results, of a pilot study of the ‘Nihongo Speech Trainer’ aimed at helping Thai learners improve their ability to identify Japanese contrasts. The pilot study was performed on 15 participants. The tool focuses on specific contrasts that are problematic for Thai learners such as Japanese fricatives and affricates. Perceptual training uses a high-variability phonetic training method (hereafter referred to as “HVPT perceptual training”). Each training session included 90 minimal pairs in which the target contrasts were embedded in initial, medial and final positions. The training stimuli were produced by seven Japanese native speakers. The results of the pilot study showed that the use of the Nihongo Speech Trainer can lead to better perception of the trained Japanese sounds. The results of a questionnaire among the participants also showed that the system helped to improve their perception and production ability. However, despite these positive results with the use of the Nihongo Speech Trainer, there is room for improvement, which may lead to better training results.

AbstractAbsolute pitch (AP), the rare ability to name any musical note without the aid of a reference note, is thought to develop in an early critical period of development. Although recent research has shown that adults can improve AP abilities in a single training session, the best learners still did not achieve note classification performance comparable to performance of a genuine AP possessor. Here, we demonstrate that genuine AP levels of performance can be trained in eight weeks for some adults, with the best learner passing all measures of AP ability after training and retaining this knowledge for at least four months after training. Alternative explanations of these positive results, such as improving accuracy through adopting a slower, relative pitch strategy, are not supported based on joint analyses of response time and accuracy. The post-training AP assessments were extensive, totaling 204 notes taken from eight different timbres and spanning over seven octaves. These results clearly demonstrate that explicit perceptual training in some adults can lead to AP performance that is behaviorally indistinguishable from AP that results from childhood development. Implications for theories of AP acquisition are discussed.

Abstract Societies in the most developed countries have witnessed a significant ageing of the population in recent decades, which increases the demand for healthcare services and caregivers. The development of technologies to help the elderly, so that they can remain active and independent for a longer time, helps to mitigate the sustainability problem posed in care services. This article follows this new trend, proposing a multi-agent system composed of a smart camera network, centralised planning agent, a virtual coach, and robotic exercise buddy, designed to promote regular physical activity habits among the elderly. The proposed system not only persuades the users to perform exercise routines, but also guides and accompanies them during exercises in order to provide effective training and engagement to the user. The different agents are combined in the system to exploit their complementary features in the quest for an effective and engaging training system. Three variants of the system, involving either a partial set of those agents or the full proposed system, were evaluated and compared through a pilot study conducted with 12 elderly users. The results demonstrate that all variants are able to guide the user in an exercise routine, but the most complete system that includes a robotic exercise buddy was the best scored by the participants. Article Highlights Proposal of a multi-agent system to help elderly adopting regular physical activity habits. A virtual coach and a robotic exercise buddy provide both guidance and companionship during the exercise. A pilot study conducted with 12 elderly users demonstrated an effective and engaging training system.

Abstract Background The aim of this study was to present a percutaneous transhepatic biliary puncture simulator that can be used without radiation exposure and that reflects the conventional anatomy of the biliary ducts and its vicinity structures. Methods An anatomically based model of the biliary tree was developed using a cord network fixed to a wooden frame. The skin, ribs, intercostal muscles, and right lower lobe pleura were simulated using foam sponge, plastic tubes, a polystyrene foam panel, and an air pad, respectively. For the puncture, we used a 20-G Chiba needle and a wire with distal double arches; these were used to troll a cord, simulating the successful puncture of a bile duct. A camera was also placed above the model to allow the trainees to train eye-hand coordination while viewing the image on a monitor in real time. The simulator was tested with 60 radiology residents to evaluate the confidence and skills transferability of the training model. Results After receiving an introduction of the system and 5 min of training under tutor surveillance, all participants were able to troll a cord of the biliary simulator by themselves in less than 4 min. Only one participant punctured the simulated pleura. The participants’ evaluations showed positive results, with increased user confidence and skills transferability after the training session. Conclusions This proposed simulator can be an effective tool to improve a trainee’s confidence and competence while achieving procedural and non-procedural interventional radiology skills related to the liver.

Electroencephalography neurofeedback (EEG-NFB) training can induce changes in the power of targeted EEG bands. The objective of this study is to enhance and evaluate the specific changes of EEG power spectral density that the brain-machine interface (BMI) users can reliably generate for power augmentation through EEG-NFB training. First, we constructed an EEG-NFB training system for power augmentation. Then, three subjects were assigned to three NFB training stages, based on a 6-day consecutive training session as one stage. The subjects received real-time feedback from their EEG signals by a robotic arm while conducting flexion and extension movement with their elbow and shoulder joints, respectively. EEG signals were compared with each NFB training stage. The training results showed that EEG beta (12–40 Hz) power increased after the NFB training for both the elbow and the shoulder joints’ movements. EEG beta power showed sustained improvements during the 3-stage training, which revealed that even the short-term training could improve EEG signals significantly. Moreover, the training effect of the shoulder joints was more obvious than that of the elbow joints. These results suggest that NFB training can improve EEG signals and clarify the specific EEG changes during the movement. Our results may even provide insights into how the neural effects of NFB can be better applied to the BMI power augmentation system and improve the performance of healthy individuals.

Abstract Background Whole-body electromyostimulation (WB-EMS) training is used in popular and health sports to improve muscular performance. Little is known about the possible psychological effects of WB-EMS training. The aim of the study is therefore to investigate the possible psychological effects of WB-EMS training on subjective well-being, relaxation, mood, and perceived stress. Materials and Methods Twenty-five healthy subjects underwent conventional WB-EMS training and Sham training (without the application of electrical stimulation) as part of a randomized, controlled pilot study in a crossover design. Subjective well-being and subjective relaxation were assessed using visual analog scales, the current state of mood was assessed with Multidimensional Mood State Questionnaires (MDBF), and the current level of stress was assessed with Recovery–Stress Questionnaires/Erholungs-Belastungs-Fragebögen (RESTQEBF) before and after training. Results WB-EMS training has a statistically significant positive effect on subjective well-being and subjective relaxation, as well as on the awake subscale of the MDBF. No significant main effect of sequence and no interaction effects were found. Also, compared to a Sham training session, a single WB-EMS training session had no significant effect on mood, nervousness, or the current level of stress. Conclusion Besides physiological effects, WB-EMS might also have a strong psychological impact. WB-EMS could be beneficial for people who, due to their limitations, have problems training on a regular basis and with adequate training intensity.

In this article, we present a taxonomy in Robot-Assisted Training; a growing body of research in Human–Robot Interaction which focuses on how robotic agents and devices can be used to enhance user’s performance during a cognitive or physical training task. Robot-Assisted Training systems have been successfully deployed to enhance the effects of a training session in various contexts, i.e., rehabilitation systems, educational environments, vocational settings, etc. The proposed taxonomy suggests a set of categories and parameters that can be used to characterize such systems, considering the current research trends and needs for the design, development and evaluation of Robot-Assisted Training systems. To this end, we review recent works and applications in Robot-Assisted Training systems, as well as related taxonomies in Human–Robot Interaction. The goal is to identify and discuss open challenges, highlighting the different aspects of a Robot-Assisted Training system, considering both robot perception and behavior control.

Mandarin Conversation

Background and Purpose: Pinyin is required in learning Mandarin. The challenge of Romanised Pinyin is that learners must decipher the meaning of words based on the change of tone. Communication research is often conducted without accounting for the effects of the change of tone in learning a language. With the aim of avoiding miscommunication while strengthening awareness, Campus Buddies Programme was employed to provide tone practice for learners and consequently explores the effectiveness of the intervention.   Methodology: This quantitative classroom-based research gathered information through the administration of a questionnaire. The questionnaire was distributed to 32 Mandarin Level 1 learners identified through purposive sampling. The students studied five topics from the syllabus. A total of 10 native speakers who scored A in Sijil Pelajaran Malaysia (SPM) mentored the learners during the programme. The participants were instructed to answer both pre- and post-tests. Part A consists of demographic details, whereas Part B focuses on the effectiveness of questions and Part C consists of 30 questions of content learned by the respondents. The data were then analysed using SPSS 26 software.   Findings: The respondents demonstrated a positive response towards the programme and suggested further improvement ideas such as prolonging the training session and adding more topics and oral activities. The results implicated the programme as a motivator for oral fluency. Many non-native speakers can benefit from conversation with Mandarin native speakers because it is a strong indicator and sound oral mastery strategy.   Contributions: This research provides insights into the effectiveness of the current programme in motivating students’ oral learning. The outcome is essential in determining the Mandarin conversation strategy. More studies adopting different variables are proposed to explore correlations from different perspectives in order to improve students’ oral learning.   Keywords: Tonal pronunciation, native speakers, non-native speakers, foreign language instruction, Mandarin conversation.   Cite as: Chua, N.

Acoustic Measure

This pilot study provides an acoustic description of the phonation types in Fuzhou Chinese. Speech samples from 5 native speakers show that tones [21 242 24] are breathy, while [44 32 4] are mainly modal and [51] is modal-breathy. Acoustic measure HNR35 can distinguish these phonation types, while H1*-A1* can only differentiate [24] and the end of [51] from other tones.

Recurrent Word

This article reports on a pilot study into how corpus methods can be applied to the study of one type of phraseological unit, formulae, in native speaker and learner speech. Formulae, or formulaic expressions, are multi-word units performing a pragmatic and/or discourse-structuring function and have been characterised as being typically native-like. The methodology presented here is contrastive and involves the use of computerised corpora of both native and non-native speaker speech. It consists of two steps: (1) the automatic extraction of all recurrent word combinations to produce lists of potential formulae, and (2) a carefully specified manual filtering process designed to reduce these lists to lists of actual formulaic usage. The results of this process allow for the first genuine quantitative comparison of formulae in the speech of native and non-native speakers, which in turn has significant implications for SLA research. This paper focuses on methodology and does not present a full discussion of the results. However, selected example findings are presented to support the approach adopted.
