“…As a result, there were 11 methods including 10 proposed methods (5 places and 2 interpolation methods) and 1 baseline method in the experiments. We used the bandlimited resampling class in torchaudio 8 and the linear interpolation function of pytorch 9 as the implementations. For the WSOLA algorithm we used audiotsm 10 package as the implementation.…”

“…Since speaking rate changes speech intelligibility and accessibility, users may need different speaking rates depending on the situation. For instance, a high speaking rate may be needed by visually-impaired people [6,7] and students who take online courses [8] since they are used to listening to speech with a higher speed. Instead, people who are in an environment with high reverberation [9] or people who have aphasia [10] and elderly adults [11,12] may need a low speaking rate to understand the content of speech.…”

This paper presents a speaking-rate-controllable HiFi-GAN neural vocoder. Original HiFi-GAN is a high-fidelity, computationally efficient, and tiny-footprint neural vocoder. We attempt to incorporate a speaking rate control function into HiFi-GAN for improving the accessibility of synthetic speech. The proposed method inserts a differentiable interpolation layer into the HiFi-GAN architecture. A signal resampling method and an image scaling method are implemented in the proposed method to warp the mel-spectrograms or hidden features of the neural vocoder. We also design and open-source a Japanese speech corpus containing three kinds of speaking rates to evaluate the proposed speaking rate control method. Experimental results of comprehensive objective and subjective evaluations demonstrate that 1) the proposed method outperforms a baseline timescale modification algorithm in speech naturalness, 2) warping mel-spectrograms by image scaling obtained the best performance among all proposed methods, and 3) the proposed speaking rate control method can be incorporated into HiFi-GAN without losing computational efficiency.

The implementation of environmental education in the world is affected by the COVID-19 pandemic, so researchers must be responsive, adjust and creative strategies to survive, and think about future anticipations. The focus and concern of researchers towards the theme of environmental education and COVID-19 is highly expected, as evidenced by the research results published in reputable journals. The purpose of this systematic literature review was to review and compare investigations of research on articles published by Scopus indexed journals. We used the phrase “environmental education and COVID-19” in the disbursement menu in Scopus Database and found 1379 articles. Furthermore, only 21 articles met the criteria to be analyzed. The inclusion and exclusion model used is PRISMA. There has been a trend of increasing publications in the last four years. Environmental education issues can be approached through qualitative, quantitative, mix-method, case studies, and R&D. The authors most in the spotlight are Lowan-Trudeau, G. (reference), Aristovnik, A. (bibliographic coupling), and Mehmood, R. (co-citation). The keywords that are mostly used by the author are COVID-19, education, higher education, and sustainable development. This environmental education keyword has branches into climate change, sustainable development, and adaptation. There are 22 countries of origin of authors who published articles, dominantly from the United States and the Republic of Korea. Articles are published equally by authors from Europe, Asia, and America. It was found that there were more articles published in collaboration between universities within one country and between countries. Rarely are articles written by a single author. There are 20 institutions that provide funding for research and publications. Most publications have fulfilled one of the ethics by declaring funding status. We succeeded in formulating and discussing a description of the existence of environmental education during the COVID-19 pandemic. These findings can serve as a consideration or baseline for researchers to study environmental education and COVID-19 themes according to their respective backgrounds and objectives.

Delivering forestry courses online: experiences, lessons learned, and future of forestry online education in the Asia Pacific

et al. 2022

Innovation in forestry education is needed to address changing contexts of the positionality of forests. This is particularly significant in the Asia–Pacific region, where deforestation and degradation are high. However, the accessibility of high-quality forestry education to address changing regional and global contexts is lacking. A series of innovative sustainable forest management (SFM) open education resource (OER) courses were developed and implemented to improve the accessibility of SFM education to enhance teaching quality, curriculum, and research capacity of universities in the Asia-Pacific Region. To evaluate the SFM-OER program in terms of student experiences, this study investigated student achievement, perceived success of the pedagogical approach and instructional design, and perceived effectiveness of the learning activities in promoting active and transformative learning through the assessment of a 1,191-course feedback survey between 2018 and 2020, including the global pandemic. This study revealed that the program attracted diverse student demographics, including a higher proportion of female students majoring in forestry, ecology, and other environmental studies. Their primary motivation to participate in the courses was to gain international experience, followed by the flexibility of online learning, mandatory course requirements, and earning course credits. Students were satisfied with the Canvas learning management system. Most students spent less than 5 to 10 h of their weekly time in the course and agreed or strongly agreed that the workloads were manageable. Students reflected positively on various learning activities and assignments, such as watching lecture videos, taking quizzes, reading and summarizing, having discussions, and peer review writing. However, they did not clearly prefer specific learning activities, signifying the importance of using diverse learning activities to satisfy diverse individual learning styles in online settings. This analysis contributes to the further development of student-centered pedagogical development for online learning and provides insight into the ways forward for online higher forestry education, while repurposing existing OER courses in a post-Covid-19 era.
