    • 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 ...
    • 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 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 ...
    • The semi-automated creation of stratified speech corpora 

      Carel van Heerden; Marelie H. Davel; Etienne Barnard (Pattern recognition association of South Africa (PRASA), 2013)
      Smartphones provide an efficient means for the collection of speech data; however, the quality of the corpora created in this fashion is not predictable. We describe an approach that allows us to post-process and rank ...
    • A smartphone-based ASR data collection tool for under-resourced languages 

      Nic J. de Vries; Marelie H. Davel; Jaco Badenhorst; Willem D. Basson; Febe de Wet; Etienne Barnard; Alta de Waal (Elsevier, 2014)
      Acoustic data collection for automatic speech recognition (ASR) purposes is a particularly challenging task when working with under-resourced languages, many of which are found in the developing world. We provide a brief ...
