    Generating fundamental frequency contours for speech synthesis in Yorùbá 

    Van Niekerk, Daniel R.; Barnard, Etienne (International Speech Communication Association ( ISCA ), 2013)
    We present methods for modelling and synthesising fundamental frequency (F0) contours suitable for application in text-to-speech (TTS) synthesis of Yorùbá (an African tone language). These methods are discussed and compared ...

    A target Approximation Intonation Model for Yorùbá TTS 

    van Niekerk, Daniël R.; Barnard, Etienne (ISCA, 2014)
    A complete intonation model based on quantitative target approximation is described for Yorùbá text-to-speech (TTS) synthesis. This model is evaluated analytically and perceptually and compared to a fundamental frequency ...

    Towards lecture transcription in resource-scarce environments 

    De Villiers, Pieter; Jooste, Petri; Van Heerden, Carel J.; Barnard, Etienne (Pattern recognition association of South Africa (PRASA), 2012)
    We present progress towards automated Lecture Transcription (LT) in resource scarce environments. Our development has focused on the transcription of lectures in Afrikaans from two faculties at North-West University. A ...

    A distributed approach to speech resource collection 

    Molapo, Raymond; Barnard, Etienne; De Wet, Febe (Pattern recognition association of South Africa (PRASA), 2013)
    We describe the integration of several tools to enable the end-to-end development of an Automatic Speech Recognition system in a typical under-resourced language. Google App Engine is employed as the core environment for ...

    A discourse model of affect for text-to-speech synthesis 

    Schlunz, Georg I.; Barnard, Etienne (Pattern recognition association of South Africa (PRASA), 2013)
    This paper introduces a model of affect to improve prosody in text-to-speech synthesis. It operates on the discourse level of text to predict the underlying linguistic factors that contribute towards emotional appraisal, ...

    A voice service for user feedback on school meals 

    Aditi Sharma, Grover; Calteaux, Caren; Barnard, Etienne; Van Huyssteen, Gerhard (ACM, 2012)
    Research using voice-based services as a technology platform for providing information access and services within developing world regions has shown much promise. The results for design and deployment of such voice-based ...

    The semi-automated creation of stratified speech corpora 

    Van Heerden, Carel; Barnard, Etienne; Davel, Marelie H. (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 ...
