Abstract

The invention discloses a Parkinsonism detecting device based on cooperative and optimal determination of voice mixing information features. The Parkinsonism detecting device comprises a signal acquisition device, a processor, and a result output module. The signal acquisition device is used for obtaining voice information of a diagnosis object; the processor consists of a feature extraction module for extracting voice features and a pre-trained classifier and whether the diagnosis object belongs to a Parkinsonism patient is determined by the classifier; and the result output module is used for outputting a determination result of the classifier. According to the Parkinsonism detecting device based on cooperative and optimal determination of voice mixing information features, the classifier is used during the diagnosis process; training and testing of lots of data are carried out; and the precision is high and the device is used conveniently.

Description

technical field [0001] The invention relates to an electronic medical device, in particular to a Parkinson's disease detection device based on synergistic optimal discrimination of voice mixed information features. Background technique [0002] Parkinson's disease is a progressive central nervous system degenerative disease that mostly occurs in middle-aged and elderly people, also known as Parkinson's disease or Parkinson's disease, and usually occurs after the age of 60. Among patients with Parkinson's disease, 50% to 80% of cases have an insidious onset, which is difficult to detect in the early stage and is often ignored, so it is easy to cause missed diagnosis. However, once the disease is formed, it will have an impact on the life of the patient. In the early stage of the disease, patients mainly present with dysfunction, such as finger tremor, speech disturbance, and dysphonia. Studies have shown that language dysfunction is one of the typical symptoms of early Park...
