Background: The increasing need for speech therapy due to our ageing population raises the demand on therapeutical resources. To meet this demand, innovative delivery of speech training is required. eHealth applications may provide a solution, as intensified and prolonged training is only possible and affordable in patients' home environment. Aim...

We investigated speech intelligibility in dysarthric and non-dysarthric speakers as measured by two commonly used metrics, ratings through the Visual Analogue Scale (VAS) and word accuracy (AcW) through orthographic transcriptions. To gain a better understanding of how acoustic-phonetic correlates could be employed to obtain more objective measures...

The majority of patients with neurological impairment like Parkinson's Disease (PD) or stroke are affected by dysarthria. Dysarthria is a motor speech impairment which negatively affects speech dimensions such as articulation and loudness. This leads to reduced intelligibility, often hindering daily life communication. Intensive and prolonged speec...

A potential consequence of the ageing population is an increased incidence of neurological diseases that cause communicative disorders. In turn, this may lead to an increasing demand of intensive and costly speech therapy. To alleviate this problem, multimedia applications in the area of telerehabilitation and web-based speech training have been de...

The demand for intensive and costly speech therapy to patients impaired by communicative disorders can potentially be alleviated by developing computer-based systems that provide au-tomatized speech therapy in the patient's home environment. In this paper we report on research aimed at developing such a system that combines serious gaming with auto...

Measuring the intelligibility of disordered speech is a common practice in both clinical and research contexts. Over the years various methods have been proposed and studied, including methods relying on subjective ratings by human judges, and objective methods based on speech technology. Many of these methods measure speech intelligibility at the...

A Show & Tell presentation in ICASSP 2016

This paper presents research on the topic of glove based ges-ture recognition. Human Computer Interaction keeps mov-ing toward interfaces which are more natural and intuitive to use, in comparison to traditional keyboard and mouse. In this paper how gestures can be recognized when using the dataglove as means of input is researched. The field of ge...
