This study is sentence generation for Augmentative and Alternative Communication. The object of sentence generation is to use in augmentative and alternative communication which is designed for those who are nonspeaking disorders. AAC generates human voice with using a sentence which is made up by the users. In order to construct a sentence, lexical information was adapted for a concept of augmentative and alternative communication. The lexical informations consist of noun types which can be connected to verbs, auxiliary words, conjugation of verbs and verb types. The system was made using lexical information and the usefulness of the sentence generation was measured by the system. The system constructed has functions of generation and saving right sentences, searching and inputting vocabularies.

This study is about Augmentative and Alternative Communication as handicapped people actively pursue their life. Especially, although there are many ways and devices for communicating the same as a normal person, descriptive supplementation and sustaining studies are needed for perfect communication as a normal person. The purpose of the paper is to help handicapped people who have hardships about communication. This study develops the function of Smart Workflow AAC(Augmentative and Alternative Communication) and IR sensor_based context aware function that can offer services convenient to classified handicapped people for helping them to communicate effectively. This system from an experimental basis has improved efficiency to communicate more harmoniously within individual handicapped situations to schedule management and communication of handicapped people.

We conducted a user-centered usability testing on the Android-based Mobile Augmentative Alternative Communication(AAC) Software. In this paper, we examined functionality, satisfaction, and ease of information searching for a specific function using a task scenario, and we investigated appropriateness of development purposes, contents, instructional strategies, usability, functions of management mode, and user interface of the mobile AAC to the communication needs of children who are nonverbal. We also examined user requirements, preference, satisfaction, and other personal opinions for the mobile AAC using an open feedback. In addition, we investigated users' preference for the size of mobile devices using 4.3", 5.0", and 7.0" mobile devices.

In this study, specific elements and functions in modules of the AAC (Augmentative and Alternative Communication) application for children with severe and multiple disabilities were elicited, and screen interface was designed accordingly. As results, screen configuration, communication display edition, audiovisual output, and switch and scanning modules were defined. Screen configuration module consists of communication category, spelling board, favorites, screen lock, and setting function. The Communication display edition module includes communication categories, symbols, and favorites edition. The audiovisual output module provides the ability to adjust the pitch, intensity, speed, and tone of the voice individually in the form of auditory output. In the form of visual output, the background color and size of the frame, border color and thickness are adjusted. The switch and scanning module provides a function to select by pressing the switch when the symbol cell is highlighted audibly and visually. The development of the AAC application designed in this study is needed.

Neurodegenerative diseases such as Parkinson's disease and amyotrophic lateral sclerosis may induce impairment of speech motor system. This review discusses the characteristics of dysarthria and symptom management for these conditions. Given the progressive nature of the neurodegenerative diseases, speech-language pathologists must be aware of appropriate augmentative and alternative communication equipment at the early stage of the disease course. Patients with neurodegenerative diseases can maintain functional communication with augmentative and alternative communication supports.

Children with language developmental disabilities often struggle through their lives from a lot of challenges in everyday life and social activities. They're often easily deprived of the opportunity to engage in social activities, because they find difficulty in understanding or using language, a core means of communication. With regard to this issue, AAC(Augmentative and Alternative Communication) can be an effective communication tool for children who are suffering from language disabilities. In this paper, we propose a deep learning-based AI service to make full use of the pictogram as an AAC tool for children with language developmental disabilities to improve not only the ability to interact with others but the capacity to understand language. Using this service, we strive to help these children to more effectively communicate their intention or desire and enhance the quality of life.

Augmentative and alternative communication(AAC) is a communication tool for those with impairments or restrictions on the production or comprehension of spoken language. Traditional AAC has used a portable board with pictures and texts with which disabled person could be supported by it. Currently, smart phone based AAC researches and developments are actively studying. With emerging concepts of context-aware computing, the mobile devices can provide mobile users with timely information and location based services. We proposed a adjustable AAC system for disabled people of which has variable layouts and selectable items. We also implemented context-ware application for AAC systems including time, location and click count informations on smart phone. The system can adaptively change its layout and select AAC items depending on various situation of disabled persons.

The present study implemented AAC(Augmentative and Alternative Communication) system using images that speech defectives can easily understand. In particular, the implementation was focused on the portability and mobility of the AAC system as well as communication system of a more flexible form. For mobility and portability, we implemented a system operable in mobile devices such as PDA so that speech defectives can communicate as food as ordinary People at any Place using the system Moreover, in order to overcome the limitation of storage space for a large volume of image data, we implemented the AAC system in client/server structure in mobile environment. What is more, for more flexible communication, we built an image dictionary by taking verbs as the base and sub-categorizing nouns according to their corresponding verbs, and regularized the types of sentences generated according to the type of verb, centering on verbs that play the most important role in composing a sentence.

In this paper, we implement an AAC(Augmentative and Alternative Communication) system based on image dictionary in order that speech defectives can easily communicate their opinion to others by using images. Normally, those who have a speech defect use only a few limited words to express their intentions and it is an effective way to use images in their communication because they have a difficulty in speaking. Therefore we make verbal images of verb and adjective that play an important role in expressing the speaker's intention, define pattern of semantic relation between the verbal images and noun images, and construct the image dictionary. In this AAC system, when a user clicks a verbal image, the system generates a sentence by selecting noun images which are component parts of corresponding pattern based on semantic relation with the verbal image. We evaluate the implemented system by how efficiently children of speech defect can express their intention and the result shows more than 70% of success rate in communication.

This paper designs and implements a sentence generation for an augmentive and alternative communication system(AAC). The AAC system is assistive communication device to help the mute language disorder communicate more freely and the system have an objected to reduce time and keystrokes for sentence generating. The paper of sentence generation make up for merits and demerits in the existing sentence generation method and in order to sentence generation. One aspect of Korean language that confines nouns defending on the verbs or postpositional words is used for sentence generation. The distinctive feature of this paper is to connect verbs to nouns using domain knowledge. We utilize the lexical information that exploits characteristics of Korean language for sentence generation. A comparison with other approaches is also presented. This sentence generation is based on lexical information by extracting characteristics of sentences.
