Virtual Reality Technology and Speech Analysis for People Who Stutter

Virtual reality (VR) technology provides an interactive computer-generated experience that artificially simulates real-life situations by creating a virtual environment that looks real and stimulates the user’s feelings. During the past few years, the use of VR technology in clinical interventions for assessment, rehabilitation and treatment have received increased attention. Accordingly, many clinical studies and applications have been proposed in the field of mental health, including anxiety disorders. Stuttering is a speech disorder in which affected individuals have a problem with the flow of speech. This can manifest in the repetition and prolongation of words or phrases, as well as in involuntary silent pauses or blocks during which the individual is unable to produce sounds. Stuttering is often accompanied by a social anxiety disorder as a secondary symptom, which requires separate treatment. In this study, we evaluated the effectiveness of using a VR environment as a medium for presenting speech training tasks. In addition, we evaluated the accuracy of a speech analyzer module in detecting stuttering events.

Peningkatan Rasa Percaya Diri Melaui Pelatihan Public Speaking pada Siswa SMK N I Selo Boyolali

Public speaking is a public speaking skill that can be trained. By continuing to do the practice of speaking in public effectively, a person can grow his self-confidence when speaking in front of many people. The importance of public speaking in one's life is to increase self-confidence. For this reason, this public speaking training activity is carried out to achieve these goals for the students of SMKN 1 Selo Boyolali. This training activity includes material presentation about public speaking, discussion sessions, training to become an MC, speech training, storytelling sessions, and game sessions. This activity is expected to provide benefits for students of SMKN 1 Selo Boyolali in increasing self-confidence.

Synchronising speech segments with musical beats in Mandarin and English singing

Generating synthesised singing voice with models trained on speech data has many advantages due to the models' flexibility and controllability. However, since the information about the temporal relationship between segments and beats are lacking in speech training data, the synthesised singing may sound off-beat at times. Therefore, the availability of the information on the temporal relationship between speech segments and music beats is crucial. The current study investigated the segment-beat synchronisation in singing data, with hypotheses formed based on the linguistics theories of P-centre and sonority hierarchy. A Mandarin corpus and an English corpus of professional singing data were manually annotated and analysed. The results showed that the presence of musical beats was more dependent on segment duration than sonority. However, the sonority hierarchy and the P-centre theory were highly related to the location of beats. Mandarin and English demonstrated cross-linguistic variations despite exhibiting common patterns.

JustSpeak: Automated, User-Configurable, Interactive Agents for Speech Tutoring

Conversational agents are widely used in many situations, especially for speech tutoring. However, their contents and functions are often pre-defined and not customizable for people without technical backgrounds, thus significantly limiting their flexibility and usability. Besides, conventional agents often cannot provide feedback in the middle of training sessions because they lack technical approaches to evaluate users' speech dynamically. We propose JustSpeak: automated and interactive speech tutoring agents with various configurable feedback mechanisms, using any speech recordings with its transcription text as the template for speech training. In JustSpeak, we developed an automated procedure to generate customized tutoring agents from user-inputted templates. Moreover, we created a set of methods to dynamically synchronize speech recognizers' behavior with the agent's tutoring progress, making it possible to detect various speech mistakes dynamically such as being stuck, mispronunciation, and rhythm deviations. Furthermore, we identified the design primitives in JustSpeak to create different novel feedback mechanisms, such as adaptive playback, follow-on training, and passive adaptation. They can be combined to create customized tutoring agents, which we demonstrate with an example for language learning. We believe JustSpeak can create more personalized speech learning opportunities by enabling tutoring agents that are customizable, always available, and easy-to-use.

Cognitive Technologies in Pedagogical and Natural Science Training for Future Psychologists in Post-Pandemic Education

In conditions of post-pandemic reality, the creation of optimal psychological and pedagogical conditions for the formation of future specialists, raising the level of their professional training, socialization and adaptation to work in the work collective requires appropriate psychological support, the development of cognitive and psychological support technologies for the constructive implementation of practical social psychological assistance in the pedagogical process, as well as the use of modern cognitive-psychological approaches by teachers, the development of psychological recommendations on the style of pedagogical impact and the like.The article highlights the important socio-psychological conditions for preparing a future teacher for socio-pedagogical activity in the context of post-pandemic realities. The necessity of using cognitive psychology technologies in the process of forming professionally speaking competencies of future psychologists and their speech culture in the process of professional speech training is substantiated. The technologies and conditions for the organization of the pedagogical process for the preparation of future practical psychologists who have undergone changes as a result of recent events related to the implementation of the educational process in a remote mode are described. The structure of the seminar on the basics of speech competence of a psychologist is presented as a result of using a dialogical approach in the system of professional training at a university.In our opinion, the materials in this article will be of interest to educators, practical psychologists, and social educators of the vocational education system, since they will help not only better understand the psychological characteristics of the professional and personal development of future specialists, but also constructively solve the urgent problems of their professional training.
