Using machine learning to analyze speech from speakers of different languages could help distinguish between Parkinson’s disease and essential tremor, two neurological disorders that can cause similar symptoms. That’s according to the study, “Automatic speech-based assessment to discriminate Parkinson’s disease from essential tremor with a…

A new machine-learning algorithm — a type of artificial intelligence or AI — that integrates facial expression and voice recordings using just a smartphone camera could help clinicians in the early detection of Parkinson’s disease, a study has found. Combining data on changes in voice and facial features with…

Analyses that estimate the length of a person’s vocal tract, which involves controlling muscles used in speech, could help to identify Parkinson’s disease, according to a new study. “The standard clinical method for classifying parkinsonian voice is by perceptual evaluation, which however is subjective,” the researchers wrote. “Computerized voice analysis…

Machine learning — a form of artificial intelligence that allows a computer to adapt, analyze, and infer from patterns in data — can distinguish by voice people with Parkinson’s disease from those without it and track disease stages by continued changes in voice quality, a study reported. Using speech recordings,…

A particular region of the brain responsible for sensing and processing speech and speech-like sounds is overly active in people with Parkinson’s disease, according to a new study. These findings may help provide a biological explanation for why Parkinson’s patients tend to speak more quietly than a given situation…

People with Parkinson’s disease verbally communicate less than those without the neurodegenerative disorder, according to a recent study that discovered that patients speak about 60% less than their healthy peers. Apart from the tremors and movement issues associated with Parkinson’s, the disease also can disrupt aspects of a…

Computer-based analyses of the voice could be used for at-home monitoring of symptom severity in people with Parkinson’s disease, a small proof-of-concept study suggests. The study, “Prediction and Estimation of Parkinson’s Disease Severity Based on Voice Signal,” was published in the Journal of Voice.

Parkinson’s disease patients living in rural areas in Iowa show improved respiratory function with group therapeutic singing delivered via telemedicine, according to a pilot study. The study, “The Feasibility of Group Therapeutic Singing Telehealth for Persons with Parkinson’s Disease in Rural Iowa,” was published in the journal…

My knees are shaking and it’s not from nervousness. This is Parkinson’s disease. Stiff muscles abound throughout my aching body. This is Parkinson’s disease. My lips quiver, my teeth click, smiles turn into frowns. This is Parkinson’s disease. My toes and fingers bend involuntarily because … this…

A voice therapy program called SPEAK OUT!, developed by the Parkinson Voice Project, can help Parkinson’s disease patients regain their ability to communicate, according to a new study. Parkinson’s patients, especially those who received the training in early stages of the disease, saw improvements in speech intensity, pitch…
