Speech production difficulties are apparent in people who stutter (PWS). PWS also have difficulties in speech perception compared to controls. It is unclear whether the speech perception difficulties in PWS are independent of, or related to, their speech production difficulties. To investigate this issue, functional MRI data were collected on 13 PWS and 13 controls whilst the participants perfo...

According to the source-filter model of speech production, speech can be represented by passing the excitation signal through the vocal tract filter. The epoch or instant of maximum excitation corresponds to the glottal closure instant. Several speech processing applications require robust epoch detection but this can be a difficult task. Although state-of-the-art epoch estimation methods can p...

BACKGROUND Hearing ability is essential for normal speech development, however the precise mechanisms linking auditory input and the improvement of speaking ability remain poorly understood. Auditory feedback during speech production is believed to play a critical role by providing the nervous system with information about speech outcomes that is used to learn and subsequently fine-tune speech ...

Research into how speech production and perception are related has a long history. Proponents of the motor theory of speech perception argued in the sixties that speech sounds are perceived in terms of the articulatory features or gestures required to produce those sounds (Liberman et al., 1967; Liberman, 1996). The prediction was that infants, who do not yet produce speech sounds, would have d...

This paper studies algorithmic strategies to effectively reduce the number of infections in susceptible-infected-recovered (SIR) epidemic models. We consider a Markov chain SIR model and its two instantiations deterministic (D-SIR) independent cascade (IC-SIR) model. investigate problem minimizing by restricting contacts under realistic constraints. Under moderate assumptions on reproduction nu...
