Automatic speech recognition for resource–scarce environments
(North-West University, 2013)Automatic speech recognition (ASR) technology has matured over the past few decades and has made significant impacts in a variety of fields, from assistive technologies to commercial products. However, ASR system development ... -
Automatic speech recognition of poor quality audio using generative adversarial networks
(North-West University (South Africa)., 2022)In this study, we investigate the use of generative adversarial networks (GANs) to improve speech recognition performance of poor quality audio obtained from a real-world source. A GAN is developed to transform acoustic ... -
Domain adaptation for speaker diarisation in low-resource environments
(North-West University (South Africa)., 2022)Speaker diarisation systems aim to answer the question \who spoke when?" and are useful in providing valuable metadata to downstream applications, such as automatic speech recognition systems. However, speaker diarisation ... -
Effective automatic speech recognition data collection for under–resourced languages
(North-West University, 2011)As building transcribed speech corpora for under–resourced languages plays a pivotal role in developing automatic speech recognition (ASR) technologies for such languages, a key step in developing these technologies is the ... -
Implementing a distributed approach for speech resource and system development
(2014)The range of applications for high-quality automatic speech recognition (ASR) systems has grown dramatically with the advent of smart phones, in which speech recognition can greatly enhance the user experience. Currently, ... -
Improving Grapheme–based speech recognition through P2G transliteration
(North-West University, 2014)Grapheme-based speech recognition systems are faster to develop, but typically do not reach the same level of performance as phoneme-based systems. Using Afrikaans speech recognition as a case study, we first analyse the ... -
Lecture transcription systems in resource–scarce environments
(North-West University, 2014)Classroom note taking is a fundamental task performed by learners on a daily basis. These notes provide learners with valuable offline study material, especially in the case of more difficult subjects. The use of class ...
