“…Interventions with people with aphasia (PWA) harness technology in increasingly diverse ways to deliver individualized impairment based programs (see for example Nouwens et al, 2013; Des Roches et al, 2015; Palmer et al, 2015), rehabilitate functional communication (Bilda, 2011; Marshall et al, 2013), promote social participation (Wilson et al, 2015), provide education (Rose et al, 2010) and enable remote delivery and continued rehabilitation in the context of limited resource (van de Sandt-Koenderman, 2011; Woolf et al, 2016). …”

Conversation therapies employing video for feedback and to facilitate outcome measurement are increasingly used with people with post-stroke aphasia and their conversation partners; however the evidence base for change in everyday interaction remains limited. We investigated the effect of Better Conversations with Aphasia (BCA), an intervention that is freely available online at https://extend.ucl.ac.uk/. Eight people with chronic agrammatic aphasia, and their regular conversation partners participated in the tailored 8 week program involving significant video feedback. We explored changes in: (i) conversation facilitators (such as multi-modal turns by people with aphasia); and (ii) conversation barriers (such as use of test questions by conversation partners). The outcome of intervention was evaluated directly by measuring change in video-recorded everyday conversations. The study employed a pre-post design with multiple 5 minute samples of conversation before and after intervention, scored by trained raters blind to the point of data collection. Group level analysis showed no significant increase in conversation facilitators. There was, however, a significant reduction in the number of conversation barriers. The case series data revealed variability in conversation behaviors across occasions for the same dyad and between different dyads. Specifically, post-intervention there was a significant increase in facilitator behaviors for two dyads, a decrease for one and no significant change for five dyads. There was a significant decrease in barrier behaviors for five dyads and no significant change for three dyads. The reduction in barrier behaviors was considerable; on average change from over eight to fewer than three barrier behaviors in 5 minutes of conversation. The pre-post design has the limitation of no comparison group. However, change occurs in targeted conversational behaviors and in people with chronic aphasia and their partners. The findings suggest change can occur after eight therapy sessions and have implications for clinical practice. A reduction in barrier behaviors may be easier to obtain, although the controlled case series results demonstrate a significant increase in conversation facilitators is also possible. The rehabilitation tool is available online and video technology was central to delivering intervention and evaluating change.

“…Kohonen neural networks have also been used to classify the correct/incorrect pronunciations of some phonemes [5]. As regards language therapy, some authors have worked on aphasia treatment using different techniques, like semantic analysis of features with mobile application and web services [6], computer applications for self-management of therapy exercises [7] or gesture recognition for people suffering from severe aphasia [8]. Most of the aforementioned proposals are centered on specific problems, like diagnosis support or speech production.…”

This paper presents an approach to automatically generate personalized plans for Speech and Language Therapy on children, based on five speech and language areas: linguistic formulation, oral structure and function, receptive language, expressive language and hearing. The approach relies on an implementation of the Partition Around Medoids (PAM) algorithm, which takes into account the profile of each child, and generates multi-level (hierarchical) clusters based on several distance measures. The new plans are created as per a K-Nearest Neighbors (KNN) criterion, combining elements from the five areas. This approach has been used in the assessment of 53 children with different disabilities, with promising results verified by expert therapists.

“…The increased understanding of aphasia and of how people with aphasia can and cannot access technology was immensely valuable for the software developer and HCI researchers and led to them taking informed design decisions outside of the workshop settings. A follow-up trial of GeST with 9 participants who had severe aphasia provided evidence of its accessibility (Marshall et al, 2013); a similar study is ongoing for EVA Park.…”
