    • Automatic Recognition of Code-Switched Speech in Sepedi 

      Modipa, Thipe Isaaih (2016)
      Code switching (CS) is a natural phenomenon that is often observed in multilingual speakers. These speakers use words, phrases or sentences from foreign languages and embed them in sentences in the primary language. ...

    • Automatic speech recognition for resource–scarce environments 

      Kleynhans, Neil Taylor (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 

      Heymans, Walter (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 

      Van Wyk, Lucas (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 

      De Vries, Nicolaas Johannes (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 ...

    • Efficient data selection for ASR 

      Kleynhans, Neil; Barnard, Etienne (Language Resources and Evaluation, 2015)
      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 ...

    • Efficient development of human language technology resources for resource-scarce languages 

      Puttkammer, Martin Johannes (2014)
      The development of linguistic data, especially annotated corpora, is imperative for the human language technology enablement of any language. The annotation process is, however, often time-consuming and expensive. As such, ...

    • Implementing a distributed approach for speech resource and system development 

      Molapo, Nkadimeng Raymond (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 

      Basson, Willem Diederick (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 

      De Villiers, Pieter Theunis (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 ...
