    • Predicting utterance pitch targets in Yoruba for tone realisation in speech synthesis 

      Van Niekerk, Daniel R.; Barnard, Etienne (Elsevier, 2014)
      Pitch is a fundamental acoustic feature of speech and as such needs to be determined during the process of speech synthesis. While a range of communicative functions are attributed to pitch variation in speech of all ...
    • 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 ...
    • Tone realisation in a Yorùbá speech recognition corpus 

      Van Niekerk, Daniël R.; Barnard, Etienne (SLTU, 2012)
      We investigate the acoustic realisation of tone in short continuous utterances in Yorùbá. Fundamental frequency (F0) contours are extracted for automatically aligned syllables from a speech corpus of 33 speakers collected ...
