Mobile phone unlocking method based on voice recognition

Abstract

The invention discloses a mobile phone unlocking method based on voice recognition, and the method comprises following steps of recording and storing standard unlocking voice; requiring the unlocking voice when requesting the user to actuate the mobile phone; inputting the voice and converting the voice into voice characteristic parameters; and comparing the voice characteristic parameters of the request user with the standard voice characteristic parameters, and enabling successful unlocking if the voice characteristic parameters are identical to the voice characteristic parameters of one authorized user. Due to the adoption of the method, the problem that the unlocking password is easy to decipher or to peer can be overcome, the collected voice information is finally converted to the voice characteristic parameters after being corrected and adjusted, so that the accuracy of the characteristic parameter calculation result is improved, and the reliability of the voice unlocking is further improved; the information content is compared with the voice characteristic parameters, the unlocking can be completed when the inputted voice characteristic parameters completely conform to the standard unlocking voice, the unlocking voice is not easy to decode, the storage security of the private data of the mobile phone is high, and the stored private data of the mobile phone is not easy to leak; and in the unlocking process, the keystroke operation is not needed, so that convenience in use can be realized.

Description

technical field [0001] The invention relates to a method for unlocking a mobile phone based on speech recognition. Background technique [0002] With the maturity of speech recognition technology, people have used this technology to achieve many valuable applications, such as voice control Voice-Command (that is, using human voice to control the movement of the machine), electronic voice Voice-Text (that is, let the computer read the article) )etc. Smartphone (Smartphone) refers to "like a personal computer, it has an independent operating system, and users can install programs provided by third-party service providers such as software and games by themselves. Through such programs, the functions of the mobile phone are continuously expanded. A general term for this type of mobile phone that can realize wireless network access through a mobile communication network. With the continuous development of science and technology and the continuous improvement of people's living ...

Most of the smart phones on the market today adopt the unlocking method of password unlocking, that is, by typing in the password and then comparing and unlocking. We know that the password composed of numbers or letter strings is easy to decipher, and it is also easy to use in public places. Being peeped by others, once the password is known by others, the private data in the phone will be leaked

[0004] With the rapid development of smart phone applications, some voice unlocking software has come out in the application market. However, the following problems generally exist in traditional voice unlocking software: (1) The collected voice information is directly converted into digital data without signal correction and adjustment. A large amount of signals are transmitted to the processor, resulting in poor accuracy of the calculation results of the voice feature parameters of the voice signal, which in turn affects the reliability of voice unlocking

(2) The traditional speech feature parameters only include the information content of the voice, not the timbre features of the user. That is to say, as long as the information content is correct, no matter whether the user is authorized or not, the unlocking can be completed, the same as the password Like unlocking, the content of voice information is easy to be heard or stolen by others, and the security of mobile phone use is still poor
