    • Reshaping the transformed LF model: generating the glottal source from the waveshape parameter Rd 

      Gobl, Christer (2017)
      Precise specification of the voice source would facilitate better modelling of expressive nuances in human spoken interaction. This paper focuses on the transformed version of the widely used LF voice source model, and ...

    • The role of voice quality in the perception of prominence in synthetic speech 

      Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe; Murphy, Andrew (2019)
      This paper explores how prominence can be modelled in speech synthesis through voice quality variation. Synthetic utterances varying in voice quality (breathy, modal, tense) were generated using a glottal source model ...

    • A system for generating voice source signals that implements the transformed LF-model parameter control 

      Wang, Zihan; Gobl, Christer (2023)
      This paper describes a system which fully implements the transformed LF glottal flow model, incorporating also the often-overlooked k-factors. A problem with the original proposal is that the global waveshape parameter ...

    • Time- and amplitude-based voice source correlates of emotional portrayals 

      Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (Springer, 2007)
      A detailed analysis of glottal source parameters is presented for emotional portrayals which included both low and high activation states: neutral, bored, sad, and happy, surprised, angry. Time- and amplitude-based glottal ...

    • Universal and language-specific perception of affect from voice 

      Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (2011)
      This paper outlines the general results of a cross-language study of perception of affect from voice. The study aims to clarify how variations in voice quality (in synthesized stimuli) can evoke different affective coloring ...

    • Voice parameter dynamics in portrayed emotions 

      Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (Firenze University Press, 2009)
      This paper is concerned with voice source variation associated with different emotional portrayals of an utterance: bored, sad, happy, surprised, angry and neutral. The source analyses involved pulse-by-pulse inverse ...

    • Voice source dynamics in intonation 

      Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (2011)
      A qualitative analysis of voice source dynamics is presented for utterances varying in focal place- ment, with falling (F) and rising (R) pitch. Source parameters, F0, EE, UP, RG, OQ and RD were obtained by manual ...
