PCB News - Performance of voiceprint recognition in security field

Voice print recognition has a bright performance in the field of security, but it still faces many problems:

Compared with the popular face recognition technology, voice print recognition is very low-key, but it does not affect the charm of this black technology: barclays, HSBC, halifax and other British Banks all support voice print recognition.The ministry of public security of China has promoted voiceprint technology throughout the country. All local public security organs are trying to improve the actual application efficiency of voiceprint information and strengthen the application of voiceprint technology in public security organs.Recently, it was announced that Siri will add voice print recognition, so that when someone says "Hey Siri," Siri can tell if the owner is calling it

So, after going through fingerprint recognition to face recognition, will voice become the new mainstream identity mode?

Voice print recognition has three advantages

Voice recognition may be more familiar to the public than voice print recognition, but the two are fundamentally different.Voice recognition is "what to say" and voice print is "who's saying it".Voice print recognition can be divided into speaker recognition and speaker recognition.

Different from other biometric methods such as face, fingerprint and iris, voice print recognition has unique advantages.First, the voice print corpus is collected in a natural way, without the need for specific movements such as blinking and swinging, and it is not restricted by light or privacy and other specific scenes, so people are more acceptable.Second, voice print recognition allows random changes in what is read, making it difficult to copy or misappropriate voice messages left online or elsewhere.The third is the low cost of use. Face recognition requires a camera, while voice print recognition only requires a microphone, which is easier to popularize

Voice print recognition in the field of security performance.

Because of this, voice print recognition technology has been applied in many fields, among which, the more prominent is the field of security and defense.In the field of security, no matter multi-dimensional prevention and control or multi-level prevention and control, voice print recognition has become an indispensable part of the audio and video fusion system.Embedding voice print recognition technology in public security check points, such as stations and hotels, or communication systems, can identify and track key personnel, help public security effectively curb and crack down on illegal ACTS, and build and strengthen a safe social and public environment.

It is worth mentioning that, with the development trend of the Internet of things, voice print recognition is more reasonable for terminal devices with small screens, and voice print recognition is expected to become one of the verification methods and service portals in the Internet of things scenario.

Many difficulties remain.

Voice print recognition is of great value in all walks of life, but it also faces many difficulties.For example, the voice print data are currently in the public security system, and it is difficult for enterprises to use these data for training.In addition, human dialects and accents, as well as different voice conditions in different emotional states, will have a certain impact on voice print recognition.It is very important and difficult to accurately judge the essential features of sound in dynamic recognition.

Conclusion: although there are many problems to be solved, there is no denying that voice print recognition has a broader application prospect.Biometric authentication technology is expected to replace all kinds of plaintext passwords, and voice print has special advantages over other voice print features. In addition to being more secure and convenient, voice collection and recognition cost is lower than face recognition, which is actually more suitable for password authentication.Maybe it won't be too long before voice print becomes a mainstream identity.
