In August, 2023, we have attended KDD and SOUPS at LA, California. In the picture below, Youxiang is attending KDD. In the picture below, Bang is presenting our poster “Voice Privacy Assistant for Monitoring In-home Voice Commands” at SOUPS.

Youxiang Zhu, Nana Lin, Xiaohui Liang, John A. Batsis, Robert M. Roth, and Brian MacWhinney Using picture description speech for dementia detection has been studied for 30 years. Despite the long history, previous models focus on identifying the differences in speech patterns between healthy subjects and patients with dementia but do not utilize the pictureContinue reading “Evaluating Picture Description Speech for Dementia Detection using Image-text Alignment (Multimodal KDD 2023)”

Bang Tran, Sai Harshavardhan Reddy Kona, Xiaohui Liang, Gabriel Ghinita, Caroline Summerour, and John A. Batsis Voice assistant systems (VAS), such as Google Assistant or Amazon Alexa, provide convenient means for users to interact verbally with online services. VAS is particularly important for users with severe health conditions or motor skills impairment. At the sameContinue reading “VPASS: Voice Privacy Assistant System for Monitoring In-home Voice Commands (SOUPS poster + PST 2023)”

In June, 2023, we have attended ICC at Rome Italy and ICASSP at Rhodes Island Greece. In the picture below, Eli is presenting our poster “Early Detection of Cognitive Decline using Voice Assistant Commands.”

The increasing number of patients living with dementia requires effective support measures. Easier access to mobile devices can provide the follow-up and monitoring of patients with dementia. The literature presents several studies on the use of mobile applications to assist patients, health professionals, and caregivers, considering the different knowledge areas, and scientific and technological contributions.Continue reading “(Related) A comprehensive systematic review on mobile applications to support dementia patients”

Eli Kurtz, Youxiang Zhu, Tiffany Driesse, Bang Tran, John A. Batsis, Robert M. Roth, and Xiaohui Liang Early detection of Alzheimer’s Disease and Related Dementias (ADRD) is critical in treating the progression of the disease. Previous studies have shown that ADRD can be detected and classified using machine learning models trained on samples of spontaneousContinue reading “Early Detection of Cognitive Decline using Voice Assistant Commands (ICASSP 2023)”
