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 ... -
Contribution of the glottal flow residual in affect related voice transformation
Gobl, Christer (2022)This paper explores the contribution of the glottal flow residual in affect-related voice transformation. This signal, which is defined as the difference between the output of the inverse filter estimating the glottal flow ... -
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 ... -
GlóRí - the glottal research instrument
Yanushevskaya, Irena; Gobl, Christer; Ní Chasaide, Ailbhe; Kane, John; Dalton, John (2014)This papers presents GlóRí - the glottal research instrument. GlóRí is a speech analysis interface which offers a flexibility and multiplicity of approaches to voice analysis. The system allows for fully automatic processing, ... -
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 ... -
Language matters in the perception of affect from voice
Yanushevskaya, Irena; Ni Chasaide, Ailbhe; Gobl, Christer (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 ... -
The LF Model in the Frequency Domain for Glottal Airflow Modelling without Aliasing Distortion
Gobl, Christer (2021)Many of the commonly used voice source models are based on piecewise elementary functions defined in the time domain. The discrete-time implementation of such models generally causes aliasing distortion, ... -
Mapping Voice to Affect: Japanese listeners
Ni Chasaide, Ailbhe; Gobl, Christer; Yanushevskaya, Irena (ISCA, 2006)This paper reports the results of perception tests administered to speakers of Japanese as part of a cross-language investigation of how voice quality and f0 combine in the signalling of affect. Three types of synthesised ... -
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 ... -
The perceptual effects of aliasing distortion in glottal flow modelling
Gobl, Christer; Wang, Zihan (2023)When modelling the glottal flow signal in a discrete- time system, the aliasing distortion that is produced is typically ignored. The assumption is that the percep- tual effects are negligible if the sampling frequency ... -
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) -
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 ...
