Toward an interpretive framework of two-dimensional speech-signal processing
Traditional representations of speech are derived from short-time segments of the signal and result in time-frequency distributions of energy such as the short-time Fourier transform and spectrogram. Speech-signal models of such representations have had utility in a variety of applications such as …

Articulatory Speech Synthesis and Speech Production Modelling
… work, we carefully argue that the articulatory speech production model has the potential to flexibly synthesize natural-quality speech sounds and to provide a compact computational model for speech production that can be beneficial to a wide range of areas in speech signal processing.

On speech processing
… important ways of communication between humans. Speech processing refers to the technology of speech signal transformations for more efficient storage and transmission, for enhanced intelligibility and ease of assimilation. According to the different purpose as above, technologies on speech …

Aspiration noise during phonation : synthesis, analysis, and pitch-scale modification
… Based on the linear source-filter model of speech production, we implement a vowel synthesizer in which the aspiration noise source is temporally modulated by the periodic source waveform. Modulations in the noise source waveform and their synchrony with the periodic source are shown to be …

Foundations of Cognitive, Affective, and Communicative Systems for Neurodiverse Individuals
… of remote data acquisition and individualized speech signal processing that seeks to characterize how individuals with few spoken words communicate using non-speech vocalizations. This research aims to build the foundation for a transdisciplinary center for the study and advancement of these …

Single-Microphone Speech Dereverberation: Modulation Domain Processing and Quality Assessment
In a reverberant enclosure, acoustic speech signals are degraded by reflections from walls, ceilings, and objects. Restoring speech quality and intelligibility from reverberated speech has received increasing interest over the past few years. Although multiple channel dereverberation methods …

A sensorimotor basis of speech communication
… of constructing a language-agnostic model of speech communication. Insights from major theories in speech science and linguistics are used to develop a conceptual framework for sensorimotor primitives in the context of control and information theory. Within this conceptual framework, …

Autoregressive hidden Markov models and the speech signal
… (HMM) and demonstrates its application to the speech signal. This new variant of the HMM is built upon the mathematical structure of the HMM and linear prediction analysis of speech signals. By incorporating these two methods into one inference algorithm, linguistic structures are inferred from …
