The BCH message banking process, voice banking, and double dipping
(2021)Significant advances have been made in interventions to maintain communication and personhood for individuals with neurodegenerative conditions. One innovation is Message Banking, a clinical approach first developed at ... -
Controlling the voice quality dimension of prosody in synthetic speech using an acoustic glottal model
(Trinity College Dublin. School of Linguistic Speech & Comm Sci. C.L.C.S., 2021)Statistical parametric speech synthesis (SPSS) offers a means of generating synthetic speech without the need for complex and extensive rules. One way in which this approach is sometimes lacking is through the use of simple ... -
Exploring the Prosody of Affective Speech
(2022)This paper introduces a research project on voice quality and affect expression. It explores affective prosody by investigating the relationship between voice source parameter changes and perceived affect. Firstly, it ... -
HMM-based speech synthesis with an acoustic glottal source model
(2009)A major cause of degradation of speech quality in HMMbased speech synthesis is the use of a simple delta pulse signal to generate the excitation of voiced speech. This paper describes a new approach to using an ... -
Integrating a voice analysis-synthesis system with a TTS framework for controlling affect and speaker identity
(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 ... -
Phonetic feature extraction for context-sensitive glottal source processing
(2014)The effectiveness of glottal source analysis is known to be dependent on the phonetic properties of its concomitant supraglottal features. Phonetic classes like nasals and fricatives are particularly problematic. Their ... -
Rd as a control parameter to explore affective correlates of the tense-lax continuum
(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
(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 Synthetic Voice for an Assistive Conversational Agent: A Survey to Discover Italian Preferences regarding Synthetic Voice's Gender and Quality Level
(2023)Based on a previous investigation, a quantitative study aimed to identify user’ preferences towards four synthetic voices of two different quality levels (classified through the sophistication of the synthesizer: low vs. ... -
WinkTalk: A Demonstration of a Multimodal Speech Synthesis Platform Linking Facial Expressions to Expressive Synthetic Voices
(Association for Computational Linguistics, 2012)This paper describes a demonstration of the WinkTalk system, which is a speech synthesis platform using expressive synthetic voices. With the help of a webcamera and facial expression analysis, the system allows the ...
