TL;DR: A novel system for pathological voice detection using convolutional neural network (CNN) as the basic architecture is presented and it will be shown that a small amount of data can be used to achieve good results in classification with this deep learning approach.
Abstract: Automatically detecting pathological voice disorders such as vocal cord paralysis or Reinke’s edema is a challenging and important medical classification problem. While deep learning techniques have achieved significant progress in the speech recognition field there has been less research work in the area of pathological voice disorders detection. A novel system for pathological voice detection using convolutional neural network (CNN) as the basic architecture is presented in this work. The novel system uses spectrograms of normal and pathological speech recordings as the input to the network. Initially Convolutional deep belief network (CDBN) are used to pre-train the weights of CNN system. This acts as a generative model to explore the structure of the input data using statistical methods. Then a CNN is trained using supervised back-propagation learning algorithm to fine tune the weights. It will be shown that a small amount of data can be used to achieve good results in classification with this deep learning approach. A performance analysis of the novel method is provided using real data from the Saarbrucken Voice database

TL;DR: In this article, a right anterior communicating artery aneurysm haemorrhage was diagnosed with acquired neurogenic foreign accent syndrome (FAS), and the authors describe perceived and spectrographically viewed changes to her speech and attempt to ascertain why EJC was perceived as foreign, stepping beyond the general path of assuming observed changes automatically explain the perceived foreignness.

TL;DR: It is demonstrated that some individuals with dysarthria have a capacity to respond positively to intervention, some months after stroke, and to maintain this improvement following 2 months of no intervention.
Abstract: Background: Dysarthria is a common post‐stroke presentation. Its management falls within the remit of the speech and language therapy profession. Little controlled evaluation of the effects of intervention for dysarthria in stroke has been reported.Aims: The study aimed to determine the effects of a period of behavioural communication intervention on communication effectiveness and intelligibility, and of the speech disorder's impact on the person with dysarthria.Methods & Procedures: Eight people with dysarthria following stroke received individually tailored intervention programmes of 16 sessions during an 8‐week period. Conversation, and reading aloud of connected speech and of single words were sampled at four points, at intervals of around 2 months: two before intervention and two after intervention. The data were perceptually evaluated by ten listeners, blind to assessment point, for the overall effectiveness of communication (conversation) and for single‐word and reading intelligibility. The impact...

TL;DR: The results showed that, as a group, there was no significant change in either speech rate or intelligibility resulting from either treatment type, however, individual speakers showed improvements in speech performance as a result of each therapy technique.
Abstract: Communication problems are a frequent symptom for people with Parkinson's disease (PD) which can have a significant impact on their quality-of-life. Deciding on the right management approach can be problematic though, as, with the exception of LSVT (R), very few studies have been published demonstrating the effectiveness of treatment techniques. The aim of this study was to compare traditional rate reduction methods with altered auditory feedback (AAF) with respect to their effectiveness to reduce speech rate and improve intelligibility in speakers with PD. Ten participants underwent both types of treatments in once weekly sessions for 6 weeks. Outcomes measures were speech rate for passage reading as well as intelligibility on both a passage reading and a monologue task. The results showed that, as a group, there was no significant change in either speech rate or intelligibility resulting from either treatment type. However, individual speakers showed improvements in speech performance as a result of each therapy technique. In most cases, these benefits persisted for at least 6 months post-treatment. Possible reasons for the variable response to treatment, as well as issues to consider when planning to use AAF devices in treatment are discussed.

TL;DR: The study of distributed systems which bring to life the vision of ubiquitous computing systems, also known as ambient intelligence, is concentrated on in this work.
Abstract: With digital equipment becoming increasingly networked, either on wired or wireless networks, for personal and professional use alike, distributed software systems have become a crucial element in information and communications technologies. The study of these systems forms the core of the ARLES' work, which is specifically concerned with defining new system software architectures, based on the use of emerging networking technologies. In this context, we concentrate on the study of distributed systems which bring to life the vision of ubiquitous computing systems, also known as ambient intelligence.

TL;DR: The Assessment of Motor and Process Skills (AMPS) is an innovative observational assessment that is used to measure the quality of a person’s performance of domestic or basic activities of daily living (ADL).
Abstract: The Assessment of Motor and Process Skills (AMPS) is an innovative observational assessment that is used to measure the quality of a person’s performance of domestic (instrumental) or basic (personal) activities of daily living (ADL). The quality of the person’s ADL performance is assessed by rating the effort, efficiency, safety, and independence of 16 ADL motor and 20 ADL process skill items. The ADL motor and ADL process skill are analogous to the goal-directed actions defined under the Activities and Participation domains of the International Classification of Functioning, Disability and Health (World Health Organization [WHO], 2001), and are thus the small units of performance that when carried out, one by one, result in the overall task being completed.
