Course Objectives: 

Course Objectives This presentation is designed to: Define the field of computational linguistics and explain its role in the development of Alternative and Augmentative Communication (AAC) devices. Discuss the current technological advances in telecommunication devices for communicatively disabled persons. List the various ways such devices can be incorporated into the evidence-based treatment practices in the field of speech-language pathology.

Abstract: 

Abstract Limited research addresses the current telecommunication products available to persons requiring AAC devices. This project’s aim is to shed light on the technological advances specific companies have made to accommodate the needs of such populations. How speech-language pathologists can increase evidence-based outcomes in their treatment practices will also be discussed.

Computational Linguistics and AAC: 

Computational Linguistics and AAC Computational linguistics (CL) is an interdisciplinary field dealing with the statistical and logic modeling of natural language (Angr, 2005). Formerly, this form of linguistics aided scientists who had specialized in the application of computers to process a natural language.

Computational Linguistics and AAC: 

Computational Linguistics and AAC Now, computational linguistics has become interdisciplinary in that it draws upon the involvement of linguists, computer scientists, and experts in artificial intelligence, cognitive psychology and logic, amongst others. In terms of AAC devices, CL is a means by which voice recognition features are developed and programmed into dedicated and non-dedicated devices, e.g Dynamyte and cell phones.

Computational Linguistics and AAC, cont.: 

Computational Linguistics and AAC, cont. In this presentation, the role of AAC and CL will be identified to increase awareness of the current telecommunication devices available to persons with communicative disabilities. Additionally, how such systems can be utilized to increase evidence-based practice in the field of speech-language pathology will also be addressed.

Computational Linguistics and AAC, cont.: 

Computational Linguistics and AAC, cont. Over the past three decades, the field of AAC has emerged as a major resource in benefiting individuals with limited or no functional communication. As part of our daily lives, everyone uses augmentative communication techniques, such as facial expressions, gestures, and writing.

Computational Linguistics and AAC, cont.: 

Computational Linguistics and AAC, cont. However, people with severe speech or language problems must rely on these standard techniques, as well as non-standard alternative communication devices, e.g. Dysarthria. Some of the latter techniques include communication boards, computer-based programs and other non-dedicated communication devices.

Computational Linguistics and AAC, cont.: 

Computational Linguistics and AAC, cont. More recently, telecommunication devices are available that allow persons to communicate as a result of data entered with a mouse, keystroke or one’s voice. Generally, these are non-dedicated devices such as laptops, electronic agendas, and cell phones.

Computational Linguistics and AAC, cont.: 

Computational Linguistics and AAC, cont. Such non-dedicated devices are offered through AT&T TTY, Internet and Relay Services and Verizon Wireless. For instance, Verizon Wireless’ VX6100 cell phone features voice recognition, text messaging, and voice automated digital dial. This device also has picture and e-mail capabilities, which are two efficient ways patients can communicate with others.

Computational Linguistics and AAC, cont.: 

Computational Linguistics and AAC, cont. These types of telecommunication tools are most useful for patients who may not qualify for or have insurance coverage that covers dedicated devices available from companies such as Dynavox.

Discussion: 

Discussion How can these devices be incorporated into the treatment of persons with communicative disabilities? After training the patient in the general functions of the device, the therapist should ask the patient to complete simple trials with assistance. Another useful therapeutic training activity includes the patient utilizing voice activated phone programs to request banking or pharmaceutical information, e.g. Walgreens, Bank One.

Discussion, cont.: 

Discussion, cont. As the patient’s level of accuracy and independence improves, such devices can serve as generalization and maintenance trials, where the patient is required to execute specific activities of daily living, e.g., calling family members using digital dial. These exercises should be designed in an objective manner, complementary to the patient’s level of accuracy and independence.

Discussion & Conclusion: 

Discussion & Conclusion More important, such tasks should encourage the patient to become a more effective communicator with persons within his or her social network. Professional should continue to investigate how current technological advances can increase evidence-based treatment outcomes in ways that increase patient’s access to economical, productive AAC devices for activities of daily living
