Speech enhancement and recognition with generative adversarial network

While taking foreign language tests, people may record responses with different environments and equipment. sometimes the recording may not be very clear. The low-quality audios can lead to unusual results in speech recognition and scoring by the scoring systems. Audios with a higher resolution (sample rates) contain richer information since greater frequency ranges can be represented in the data, capturing greater level of detail and texture to produce high-quality audio, such as sibilants and fricatives.

Speech enhancement and recognition with generative adversarial network

While taking foreign language tests, people may record responses with different background noises. The contaminated audios can lead to unusual results in speech recognition and scoring by the scoring systems. Pearson would like to develop a more robust system for the automated speech recognition machine to work with clean and noisy records. Audio files are typically from 5 to 90 seconds long. There are popular softwares which are built to address these problems, but their results need to be tested with the particular kinds of inputs that is obtained as test responses.

How Teachers Understand Self-Regulation: Connecting the Canadian Self-Regulation Initiative with Pearson Canada Inc

The notion of ‘self-regulation’ in the development of children and young people and the health of adults has taken on considerable importance, especially in education, as the science investigating this feature has made significant advances over the last decade. One nationwide initiative, the Canadian Self-Regulation Initiative (CSRI), has been working since 2012 to support educators’ understanding about self-regulation and their ability to integrate these ideas into their practice.

Manitoba Mathematics Action Research Project

Recently PLS has signed a contract with the Ministry of Education in Manitoba. The province has been experiencing declining math scores across the province in both international tests such as PISA and in their provincial standardized tests. Manitoba is deeply committed to improving students mathematical achievement and as a result has hired PLS to develop an evidence based professional learning model that will help deepen teachers understanding of math and pedagogy, and to measure the impact of this professional learning on student achievement.

PeerScholar in the K-12 Educational System

This project explored the effectiveness of an educational technology called peerScholar, which is an online peer-assessment tool used to enhance student learning. To date, all of the findings on peerScholar have focused on the development of critical thinking skills at the University level. However, given that learning begins earlier, the proposed research will examine the effectiveness of peer-assessment, via peerScholar, throughout Grades 9 to 12. The goal Is to replicate, and to extend, the peer-assessment findings with younger students.
