“…Before proceeding with the case description, we will describe the general process of vocabulary selection and issues related to selection of messages in the clinical setting. Finally, messages selected for our case using this vocabulary selection process will be compared with a number of standard vocabulary lists (Yorkston, Dowden, Honsinger, Marriner, & Smith, 1988) and implications for the future development of more efficient vocabulary selection procedures will be described.…”

In this article, the process of vocabulary selection is described for a nonreading, severely physically disabled adult for whom an initial expressive communication approach was being developed. The process included use of environmental inventories, communication diaries, and review of standard vocabulary lists as a means of message selection. A comparison of this user's vocabulary list with 11 standard vocabulary lists indicated that even the largest of these vocabulary lists do not contain all the words considered important by the user. Thus, review of standard vocabulary lists may be considered a necessary but not sufficient aspect of vocabulary selection.

“…An individual using a communication aid that has a fixed set of words (vocabulary) may not have access to the very personalised, low-frequency, or context-specific words required to adapt their communication 35 . For those using alphabetic typing, non-adaptive word prediction may result in a more static use of language and may poorly predict fringe vocabulary 36 .…”

Use of voice output communication aids (VOCAs) can be a very effective strategy to assist people with speech impairments in communicating. Despite this, people who use communication aids often express frustration with VOCAs -desiring devices that are simpler, quicker and more effective to use.Whilst it is not possible to resolve all these issues with technology, we argue that significant progress can be made. The use of contextual information is one development that could improve the simplicity and effectiveness of communication aid design. Individuals using a VOCA also face constraints related to the selection of these items.Those using text representation will need to select around 27-40 items (unless using an ambiguous keyboard 5 ), whereas those using graphic symbols may need to select from as many as 4000 items. To navigate this number of items the user is required to make a series of selections Individuals use a range of strategies to select items on a VOCA -some may be able to press directly onto a screen or keyboard (known as direct access), whereas others may have difficulties with co-ordination or control and require alternative access devices. These devices can include alternative keyboards (for example those with key 'guards'), alternative mice (for example, eye gaze or head movement selection), or other controls such as switches. Switches are binary (non-latched) 'buttons' that come in a range of types -with varying size, shape, activation force or method. When using a switch, the user will either press it to select the desired item from a list of items through which the computer is scrolling, or use multiple switches to manually 'move' through the possible selections and then select the desired item 7 .There are few studies measuring actual input or output (speaking) rates of VOCA users, however for text production an output (measured in words per minute -wpm) of less than 5 wpm for switch access 8 , or less than or around 10 wpm for AAC users using any mode 9,10 has been suggested. This can be compared to studies of typing on 'soft' keyboards that suggest rates of between 8-20wpm 11 . As the speaking rate of a typical speaker during conversation may be between 100 and 200 wpm 12,13 it can be seen that current AAC output is in the region of an order of magnitude slower than spoken speech.People who use AAC and VOCAs often cite challenges and frustrations related to the speed of communication using these systems and also in their simplicity of use 14,15 . This has been a focus of prior work carried out as part of the NIHR Devices for Dignity (D4D) Healthcare example, the iOS8 word prediction keyboard claims to take into account " your text messaging style", "who you're writing to", "what the conversation is about" and "how you email" 34 . The Use of Context for Augmentative CommunicationPeople who use AAC may be able to process and use the context of a conversation receptively in the same way as any other individual. However, their operational use of this contextual information is much mo...

“…The participants' work supervisors identified words that they considered to be functional for the participants from a 744-word vocabulary list (Yorkston, Dowden, Honsinger, Marriner, & Smith, 1988). From the supervisors' lists, we selected single-syllable words that began with frequently occurring letters and from which minimal pairs of words differing only in onsets could be formed (e.g., mall, call).…”

Purpose: We explored alphabet supplementation as an augmentative and alternative communication strategy for adults with minimal literacy. Study 1's goal was to teach onset-letter selection with spoken words and assess generalization to untaught words, demonstrating the alphabetic principle. Study 2 incorporated alphabet supplementation within a naming task and then assessed effects on speech intelligibility. Method: Three men with intellectual disabilities (ID) and low speech intelligibility participated. Study 1 used a multipleprobe design, across three 20-word sets, to show that our computer-based training improved onset-letter selection. We also probed generalization to untrained words. Study 2 taught onset-letter selection for 30 new words chosen for functionality. Five listeners transcribed speech samples of the 30 words in 2 conditions: speech only and speech with alphabet supplementation. Results: Across studies 1 and 2, participants demonstrated onset-letter selection for at least 90 words. Study 1 showed evidence of the alphabetic principle for some but not all word sets. In study 2, participants readily used alphabet supplementation, enabling listeners to understand twice as many words. Conclusions: This is the first demonstration of alphabet supplementation in individuals with ID and minimal literacy. The large number of words learned holds promise both for improving communication and providing a foundation for improved literacy.
