Embodiment Construction

[0022] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] In the embodiment of the present invention, a method that can better describe the irregularity of pathological voices is adopted, new parameters are added in the quantization of SNR, and non-linear parameters are used to supplement the classic parameters. It is required to select different feature parameters to build a training model. Moreover, the embodiment of the present invention also uses cepstrum technology to extract cepstrum parameters. Optimize the selection of the extracted parameters, establish a regression analysis model, and digitize the evaluation results, so as to ...

Abstract

The invention belongs to the technical field of noise detection, and provides a detection method for pathological voice. The method comprises the following steps of collecting the voice of a patient to be detected, conducting characteristic parameter extraction and selection on the collected voice signal, enabling optimized parameters to enter a constructed classifier model for conducting disorder grade evaluation, and outputting the detected voice disorder grading result. According to the detection method for the pathological voice, a computer and scientific judging standards are used, a professional voice processing algorithm is adopted, a doctor can be partially or completely replaced for diagnosing the patient, the result is used as the diagnosis reference for the doctor, and the contingency of the diagnostic process is reduced to the greatest extent. In addition, the detection method is easy to implement, convenient to use and high in diagnosis accuracy, an ordinary medical worker can master the detection method through simple training, the defect that medical resources are not enough in remote areas and small cities is overcome to some extent, and the disease of the patient can be diagnosed nearby and treated as soon as possible. Moreover, the specific and quantified grading mode is provided for the voice disorder, corresponding data logs are provided at each stage in the treatment process of the patient, the doctor can completely track and know the state of the disease through the data, and the treatment process of the patient is ensured to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of voice detection, in particular to a detection method, system and computer for pathological voice. Background technique [0002] Language is an essential tool for human communication and is closely related to human life. Voice damage will directly affect a person's ability to express, and even affect the communication between people. According to reports, with the increasingly frequent social interactions, the incidence of voice diseases is also increasing year by year, accounting for about 5%-10% of ENT diseases, and about 30% of them have unhealthy voice problems, which has also aroused people's concern Emphasis on voice disorders. Early detection of voice lesions can minimize the pain and financial burden of patients. [0003] At present, the most widely used voice detection method is the assessment of voice perception based on the subjective judgment of doctors. However, due to the influence of man...
