Abstract

The invention relates to a dysphagia recognition method and equipment based on laryngeal voice information and a device. The method comprises the steps of collecting the laryngeal voice information of a subject based on a laryngeal vibrator; extracting audio features in the throat voice information; and according to the audio features, based on a pre-trained integrated classifier, obtaining an identification result of the subject. The laryngeal voice information of the subject is collected based on the laryngeal vibrator, so that the working efficiency of medical workers can be improved, the diagnosis range of dysphagia can be expanded, the laryngeal vibrator does not cause adverse effects on the subject, and the cost of collecting the laryngeal voice information of the subject based on the laryngeal vibrator is low. And the recognition result of the subject is obtained based on the pre-trained integrated classifier according to the audio features, so that compared with a single classifier, the recognition efficiency is higher, and the accuracy is higher.

Description

technical field [0001] The present application relates to the technical field of machine learning, and in particular to a method, device and device for identifying swallowing disorders based on voice information of the throat. Background technique [0002] Dysphagia refers to the inability to safely and effectively transport food to the stomach to obtain sufficient nutrition and water due to damage to the structure and (or) function of the jaw, lips, tongue, soft palate, throat, esophagus and other organs. At present, swallowing disorders are mainly detected clinically by means of contrast swallowing examination (VFSS), which observes the situation of patients swallowing food boluses wrapped by contrast agents of different viscosities and different volumes under X-ray fluoroscopy. The different phases of swallowing are assessed. This operation is radioactive, and there is a risk of contrast agent aspiration, and the amount of aspiration cannot be measured quantitatively, an...
