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 ... -
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; Murphy, Andrew (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 ... -
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 ... -
Pitch declination and reset as a function of utterance duration in conversational speech data
Yanushevskaya, Irena; Gobl, Christer; Murphy, Andrew (2015) -
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 ...
