Today I will talk to you about the basic concepts related to voiceprint. I hope it will be helpful to you!
1. The concept of voiceprint
In real life, fingerprint recognition may be more common. Common usage scenarios include mobile phone fingerprint recognition, smart door fingerprint recognition, etc. So what is What about voiceprint?
Voiceprints can actually be used similarly to fingerprints in order to distinguish characteristics that are different from other people. Simply put, it is the characteristics that distinguish one person's voice from others.
2. Introduction to voiceprint recognition
Voiceprint recognition is a type of biometric technology and a category of speech recognition technology. Voiceprint recognition mainly includes two processes: voiceprint registration and voiceprint identification. To put it simply, voiceprint recognition is to convert human vocal signals into electrical signals, then perform feature extraction, modeling, and finally match judgment.
3. Comparison between voiceprint recognition and speech recognition
3.1 Common points
Both belong to the processing of voice front-end signals.
3.2 Differences
3.2.1 Speech recognition
The focus of speech recognition is to pursue the unity and universality of sound. This is also easy to understand. For example, speech-to-text, no matter your accent, dialect, or speaking speed, the final technology is to correctly translate into the same text; the same is true for the voice assistant that comes with the mobile phone, operating the mobile phone through voice commands , no matter where the mobile phone user is, they ultimately want to recognize it as a unified command, and then complete the corresponding mobile phone operations. Common ones include "open WeChat", "today's weather", "play music" and so on.
3.2.2 Voiceprint recognition
Voiceprint recognition pursues the personality of the voice, and mainly determines whether the voice source is the same person based on the expression in different scenes. For example, WeChat's own voice login system uses voiceprint recognition technology. First, personal voiceprint information is entered and registered, and then the voiceprint is determined when identity verification is needed in the future.
4. Application scenarios of voiceprint recognition
The application scenarios of voiceprint recognition mainly include voiceprint identification and voiceprint confirmation.
4.1 Voiceprint recognition
Voiceprint recognition is mainly used for voice retrieval and identification within the scope of the voice database, that is, to find the identity of the speaker in a massive voiceprint database. For example, in the financial sales field, the customer's voiceprint information can be compared with the historical voiceprint database, and then it can be determined whether the current customer is the first purchaser or has purchased before, so that the salesperson can adjust the corresponding sales strategy.
4.2 Voiceprint confirmation
Voiceprint confirmation is mainly used in identity authentication, security access verification and other scenarios. The system performs voice authentication on the speaker, so that the platform can confirm the identity of the authenticator. OK, voiceprint confirmation has higher requirements on the input quality of the voice. Generally, it will be authenticated only for some very important information, such as changing passwords, changing mobile phone numbers and other operations that require very high security.

1. First of all, there is no function to directly cancel identity authentication in WeChat, but you can cancel the real-name authentication by logging out of WeChat Pay, and you can still chat normally after canceling it. 2. Open the WeChat app, click [Me] in the lower right corner, and select the [Service] option. 3. Click [Wallet], find and click the [Payment Settings] option, and select [Log out of WeChat Payment]. 4. When the user meets the conditions for logging out of WeChat Pay, he or she can log out according to the system prompts.

How to use the Hyperf framework for authentication In modern web applications, user authentication is a very important function. To protect sensitive information and ensure application security, authentication ensures that only authenticated users can access restricted resources. Hyperf is a high-performance PHP framework based on Swoole that provides many modern and efficient functions and tools. In the Hyperf framework, we can use a variety of methods to implement identity authentication. Two of the commonly used methods will be introduced below.

Overview of how to use PHP to implement authentication control based on identity authentication: Identity authentication is an important part of protecting application data and functional security. Authentication is the process of verifying that a user has permission to access specific resources. In PHP applications, developers can use different methods to implement authentication-based authentication control. This article will introduce how to use PHP to implement authentication control based on identity authentication, and provide code examples to illustrate. User authentication User authentication is the basis of identity authentication. Common user authentication methods include basic identity authentication (B

How to use PHP to implement face recognition and identity authentication functions. Face recognition technology, as a biometric identification technology, has been widely used in recent years. It can extract and compare features through face images captured by cameras to achieve functions such as identity authentication. In this article, we will introduce how to use PHP to implement face recognition and identity authentication functions, and give code examples. 1. Preparation First, we need a library that can perform face recognition. In PHP, we can use the OpenCV extension

In modern web application development, security has become an integral part. Authentication and authorization are crucial in this regard, as they ensure that only authorized users can access protected resources. There are many authentication and authorization mechanisms available, of which JWT (JSONWebToken) is a particularly popular mechanism because it is simple, flexible, scalable and secure. In this article, we will explore how to use PHP and JWT for authentication and authorization. First

How to handle user identity authentication and authorization in Vue technology development In Vue technology development, user identity authentication and authorization are a very important part. Identity authentication is the process of confirming the user's identity, while authorization is the granting of corresponding permissions based on the user's identity. This article will introduce how to handle user authentication and authorization in Vue development, and provide some specific code examples. User identity authentication User identity authentication generally includes user name and password verification, third-party login verification, etc. In Vue development, we can use some common authentication

With the continuous development of WeChat mini programs, more and more companies and individuals are beginning to transform their businesses and ideas into WeChat mini programs. In these small programs, face recognition and identity authentication have become an indispensable part. Therefore, this article will introduce how to use PHP to develop face recognition and identity authentication functions in WeChat mini programs, and share some practical tips. 1. Face recognition skills 1. Face recognition technology is relatively complicated with the help of third-party APIs. Therefore, in order to better realize face recognition, we can consider introducing third-party APIs
