  • The ABAIR Initiative: Bringing Spoken Irish into the Digital Space 

    Ni Chiarain, Neasa; Gobl, Christer; Ni Chasaide, Ailbhe; Murphy, Andrew (2017)
    The processes of language demise take hold when a language ceases to belong to the mainstream of life’s activities. Digital communication technology increasingly pervades all aspects of modern life. Languages not digitally ...
  • Affect Expression: Global and Local Control of Voice Source Parameters 

    Yanushevskaya, Irena; Gobl, Christer; Murphy, Andrew; Ni Chasaide, Ailbhe (2022)
    This paper explores how the acoustic characteristics of the voice signal affect. It considers the proposition that the cueing of affect relies on variations in voice source parameters (includ- ing f0) that involve both ...
  • Comparison of time and frequency domain measures of the voice source 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe; Murphy, Andrew (2019)
    Voice source modulation is of fundamental importance in speech communication. Many parameters have been proposed to capture the characteristics of the voice, but it is not always clear how the different kinds of parameters ...
  • Cross-language differences in how voice quality and f0 contours map to affect 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe (2018)
    The relationship between prosody and perceived affect involves multiple variables. This paper explores the interplay of three: voice quality, f0 contour, and the hearer's language background. Perception tests were conducted ...
  • Exploiting time and frequency domain measures for precise voice source parameterisation 

    Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (2012)
    Much of our research has focused on the role of the voice source in the prosody of spoken language, including its linguis- tic and expressive dimensions. However, as automatic methods, both for deriving the voice source ...
  • An exploration of voice source correlates of focus 

    Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (2010)
    This pilot study explores how the voice source parameters vary in focally accented syllables. It examines the dynamics of the voice source parameters in an all-voiced short declarative utterance in which the focus placement ...
  • Global waveshape parameter Rd in signaling focal prominence: Perceptual salience in the absence of f0 variation 

    Yanushevskaya, Irena; Murphy, Andrew; Gobl, Christer; Ni Chasaide, Ailbhe (2022)
    This paper explores perceptual salience of voice source parameter manipulation in signaling prominence in the absence of f0 variation. Synthetic stimuli were generated based on an inverse filtered all-voiced utterance “We ...
  • Integrating a voice analysis-synthesis system with a TTS framework for controlling affect and speaker identity 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe (2021)
    This paper reports an experiment exploring how a voice analysis-synthesis system, GlórCáil, can be used to add expressiveness to the synthetic voice in text-to-speech (TTS) systems. This implementation focuses on the Irish ...
  • Language matters in the perception of affect from voice 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe (Ivanovo State University of Technology, 2012)
  • Leveraging Phonetic and Speech Research for Irish Language Revitalisation and Maintenance 

    Ni Chiarain, Neasa; Gobl, Christer; Ni Chasaide, Ailbhe; Barnes, Emily (2019)
    The ABAIR initiative illustrates how phonetic research can drive innovative applications that provide endangered-language communities with powerful tools and resources for language maintenance and revitalisation. ABAIR ...
  • Perceived loudness and voice quality in affect cueing 

    Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (2009)
    The paper describes an auditory experiment aimed at testing whether the intrinsic loudness of a stimulus with a given voice quality influences the way in which it signals affect. Synthesised voice quality stimuli in which ...
  • Perceptual salience of voice source parameters in signaling focal prominence 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe; Murphy, Andrew (2016)
    paper describes listening tests investigating the perceptual role of voice source parameters (other than F0) in signaling focal prominence. Synthesized stimuli were constructed on the basis of an inverse filtered utterance ...
  • Prosody of voice: declination, sentence mode and interaction with prominence 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe (2015)
    This paper looks at voice source correlates of decli- nation. This follows a line of research that proposes that prosody is primarily signalled by the temporal modulation of the voice source, and not just F0. In- verse ...
  • Rd as a control parameter to explore affective correlates of the tense-lax continuum 

    Yanushevskaya, Irena; Gobl, Christer; Ni Chasaide, Ailbhe; Murphy, Andrew (2017)
    This study uses the Rd glottal waveshape parameter to simulate the phonatory tense-lax continuum and to explore its affective correlates in terms of activation and valence. Based on a natural utterance which was inverse ...
  • 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 ...
  • An Sc?ala?: autonomous learners harnessing speech and language technologies 

    Ni Chiarain, Neasa; Ni Chasaide, Ailbhe (ISCA, 2019)
    This paper presents an autonomous language learning platform which has speech and language technology at its core. An Scealaí ('the Storyteller') is a web-based interactive iCALL system that allows learners to compose ...
  • Time- and amplitude-based voice source correlates of emotional portrayals 

    Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (Springer, 2007)
