Problems solved by technology

However, the current hearing aids only have a very simple information transmission function, without voice recognition function, and cannot make fraud judgments. Sometimes the elderly will easily fall into the trap of fraudsters. You can consider using hearing aids to obtain the content of calls between the elderly and criminals. And use voice recognition technology to analyze and judge the content of the call, so as to prevent the elderly from being cheated

Embodiment 1

[0062] Such as figure 1 , The present invention provides a fraud prevention method based on voice recognition, the method includes the steps:

[0063] S1: Obtain the content of the call through the hearing aid.

[0064] In this step, the content of the call between the user and the callee is obtained through the hearing aid, which facilitates subsequent analysis and judgment of the content of the call.

[0065] S2: Use the classifier on the hearing aid to analyze the content of the call.

[0066] In this step, a classifier is preset on the hearing aid, and a preset voice recognition model is pre-stored in the classifier, and the classifier compares with the preset voice recognition model after acquiring the content of the call. Among them, there are at least two types of preset speech recognition models, in order: fraud call content model and sales call content model. The classifier compares each call content acquired with all preset voice recognition models in turn to obtain an analy...

Embodiment 2

[0078] In the embodiment of the present application, after analyzing the content of the call using the classifier on the hearing aid, the method further includes the following steps:

[0079] Determine whether the call content triggers a preset keyword;

[0080] When a preset keyword is triggered, the classifier will make a similar judgment with the preset speech recognition model;

[0081] When the preset keyword is not triggered, the classifier judges it as normal content.

[0082] In the embodiments of this application, considering that hearing aids may acquire more call content at certain times, if they are compared with the preset speech recognition model one by one, the amount of data processing will increase. You can use the hearing aid first The classifier of Analyzes the content of the call and then performs keyword judgment.

[0083] For example, if the keywords are "money" and "payment", when these keywords appear in the content of the call, you can directly enter the step o...

Embodiment 3

[0085] In the embodiment of the present application, after determining that the content of the call is sales content or fraudulent content, the method further includes the following steps:

[0086] Determine whether the voice of the call content is similar to the preset family voiceprint library;

[0087] When it is judged that the two are similar, judge that the content of the call is normal content;

[0088] When it is judged that the two are not similar, continue to judge that the content of the call is sales content or fraudulent content.

[0089] In the embodiment of this application, the family member’s voiceprint library may be stored in the hearing aid in advance. When it is judged to be fraud or promotion, it can be compared with the family member’s voiceprint library first. If it is the family member’s voice, fraud or Suspicion of marketing. This operation can prevent the embarrassment of mistaking it for sales or fraud when discussing certain high-frequency words such as "...

Abstract

The invention discloses an anti-fraud method based on voice recognition and an anti-fraud hearing aid. The method comprises the following steps: obtaining call content through the hearing aid; analyzing the call content by using a classifier on the hearing aid; judging whether the call content is similar to a preset voice recognition model or not; when the two pieces of content are similar, judging that the call content is sales promotion content or fraud content; when the two pieces of content are not similar, judging that the call content is normal content; when it is judged that the call content is sales promotion content, obtaining and pushing related negative information of the sales promotion content to family members of the user; when it is judged that the call content is fraud content, shielding the hearing aid and sending alarm information to family members of the user; and when the call content is judged to be the normal content, continuing the normal work of the hearing aid.According to the method and the hearing aid provided by the invention, the call content of the hearing aid can be filtered by upgrading the function of the hearing aid, so that the risk that the oldare fraudulent is reduced.

Description

Technical field [0001] The invention belongs to the field of anti-fraud technology, and specifically relates to an anti-fraud method based on voice recognition and an anti-fraud hearing aid. Background technique [0002] At present, it is slowly entering an aging society, but the elderly lack the awareness of self-protection and are easy to believe in fraudulent lies. This will not only bring property losses, but also cause great physical and mental damage. Although people are aware of the harm of fraud, it is worth noting that in today's social life, various successful cases of fraud will continue to be exposed. Therefore, there is an urgent need to prevent such fraud on the scientific and technical level. Especially for the elderly. [0003] At present, many elderly people often wear hearing aids for auxiliary calls. When outsiders talk to the elderly, the hearing aids must be used as the medium of the conversation to exchange information with the elderly. However, the current ...
