Study on voice-assisted technology shows promise for therapeutic use

Findings published in JMIR Rehabilitation and Assistive Technologies reported the professional experiences of UK speech and language therapists using voice-assisted technology (VAT) (e.g. Alexa, Siri) with their clients to identify the potential applications and barriers to VAT adoption and thereby inform future directions of research.

They reported using VAT with 10 different client groups, such as people with dysarthria (a motor speech disorder which causes issues with speech quality and clarity) and users of augmentative and alternative communication technologies.

Many reported using the to improve their clients' speech, to facilitate speech practice at home, and to enhance articulation and volume.

Most therapists indicated that they would like to try VAT in the future, stating that it could have a positive impact on their clients' speech, independence, and confidence.

Dr. Orla Duffy from Ulster University says that " and language therapy (SLT) is an allied health profession concerned with the assessment, diagnosis, and treatment of a range of both communication and swallowing disorders."

Speech and language therapists support a broad range of people within pediatric and and work within a wide range of settings.

Despite providing a core service within rehabilitative and —particularly in acquired or degenerative neurological conditions—SLT, similar to many other services, has been affected by funding cuts.

A survey by the Royal College of Speech and Language Therapists suggests that over 80% of services in the National Health Service face reduced staffing, narrowing scope of services and, for 8% of the services, abolishment of services altogether.

Augmentative and alternative communication (AAC) is a term used to describe various methods of aided communication, including nonverbal strategies such as gestures or , the use of picture books or communication charts, or a range of different technologies that can act as a substitute vocal communication aid.

Dr. Roisin McNaney from Monash University says that "although AAC is a well-established field with clinically proven benefits, we, and other researchers, have also been investigating other areas of technology innovation within the field of SLT, particularly those that exploit the benefits of low-cost, off-the-shelf consumer technology."

The research teams from Monash University and Ulster University concluded that VAT has been used by a number of UK-based SaLTs in clinical practice.

Pranav Kulkarni, Ph.D. candidate from Monash University, says that "wider adoption of the technology is limited by the lack of professional opportunities, training, and understanding. Although other studies have explored the interaction between technology and several client groups, this study presents opportunities and challenges from the perspective of the practitioners."

The data show increased engagement and empowerment, and the possibility of achieving therapeutic outcomes in clients with impairment.

The disparate responses suggest that this area is ripe for the development of research exploring the role of VATs in evidence-based , starting with a clear definition of its use potentials and benefits and the development of plans for outcome measurement when using VAT devices to support therapy aims.
