Provision of powered communication aids in the United Kingdom.

AAC service provision in the United Kingdom (UK) has evolved since the first service dedicated to the provision of communication aids opened in 1986. Within the UK, many health and care services are provided via government funding; however, the assessment and provision of AAC and specifically of speech-generating devices (SGDs) is inconsistent and inequitable. The study reported in this paper aimed to collect information on levels of current provision of powered communication aids (the term used in the study to refer to SGDs) by UK service providers in 2013 with the intention of improving future estimates for need of services. A questionnaire survey was designed and data were obtained from 98 AAC services across the UK. Service providers reported the number of individuals known to be using powered communication aids and the mean value reported was 0.0155% of the services' catchment populations. However levels of service provision reported were highly variable. Although the data reported must be treated with caution, it adds to the sparse literature on the topic, informs AAC service design and delivery in the UK, and acts as an indicative baseline measure for future service development.

Prevalence of people who could benefit from augmentative and alternative communication (AAC) in the UK: determining the need.

BACKGROUND: Commissioners and providers require information relating to the number of people requiring a service in order to ensure provision is appropriate and equitable for the population they serve. There is little epidemiological evidence available regarding the prevalence of people who could benefit from augmentative and alternative communication (AAC) in the UK. AIM: To determine the prevalence of people who could benefit from AAC in the UK. METHODS & PROCEDURES: An epidemiological approach was taken to create a new estimate of need: the prevalence of the main medical conditions and specific symptoms leading to the requirement for AAC were identified from the literature and AAC specialists were consulted to estimate the number of people who may require AAC. OUTCOMES & RESULTS: A total of 97.8% of the total number of people who could benefit from AAC have nine medical conditions: dementia, Parkinson's disease, autism, learning disability, stroke, cerebral palsy, head injury, multiple sclerosis and motor neurone disease. The total expectation is that 536 people per 100 000 of the UK population (approximately 0.5%) could benefit from AAC. CONCLUSIONS & IMPLICATIONS: To provide accurate figures on the potential need for and use of AAC, data need to be consistently and accurately recorded and regularly reviewed at a community level. The existing data suggest an urgent need for more accurate and up to date information to be captured about the need for AAC in the UK to provide better services and ensure access to AAC strategies, equipment and support.

Reconstructing the voice of an individual following laryngectomy.

This case study describes the generation of a synthetic voice resembling that of an individual before she underwent a laryngectomy. Recordings of this person (6-7 min) speaking prior to the operation were used to create the voice. Synthesis was based on statistical speech models and this method allows models pre-trained on many speakers to be adapted to resemble an individual voice. The results of a listening test in which participants were asked to judge the similarity of the synthetic voice to the pre-operation (target) voice are reported. Members of the patient's family were asked to make a similar judgment. These experiments show that, for most listeners, the voice is quite convincing despite the low quality and small quantity of adaptation data.

Can readers fully adopt the perspective of the protagonist?

Despite the centrality of the protagonist during narrative comprehension, evidence indicates that readers do not typically approach the text from the protagonist's point of view. Experiments 1a-1c demonstrated that both explicit task instructions and the first-person point of view resulted in comprehension being influenced by perspective-relevant information; this indicated that readers were adopting the perspective of the protagonist. However, Experiments 2a-3b showed that even when readers adopt the protagonist's perspective, they cannot do so to the exclusion of related perspective-irrelevant information. Results are discussed in the context of the RI-Val model of comprehension in which perspective-relevant information and perspective-irrelevant information are both available and compete for influence during comprehension.

Taking the perspective of the narrator.

Readers do not always adopt the perspective of the protagonist; however, they will under certain conditions. Experiments 1a and 1b showed that readers will take the perspective of the protagonist from the third-person point of view, but only when explicitly instructed to do so. Experiment 2 demonstrated that reading from the first-person point of view is a text-based manipulation that encourages readers to adopt the perspective of the protagonist. The results of Experiments 3a and 3b replicated the findings of Experiments 1a and 2. Experiment 4 established that simply increasing readers' attention to the text does not lead to adoption of the protagonist's perspective; moreover, this suggests that when it does occur, protagonist perspective adoption is not the result of increased attention, but strategic processing.
