Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] The voice recognition method is made into a software module and built into a mobile terminal (such as a mobile phone, which is described below with a mobile phone as an example). The following is the process of identity verification based on voice recognition for this mobile terminal: the specific steps are as follows:
[0026] (1) Connection and standby steps: After starting up, the mobile phone connects to the server of the mobile network operator or service provider through the wireless communication unit and the network connection unit, and activates the MMS service. If the connection is all successful, that is, in the next step, the network is not covered or the MMS service is not opened, etc., and some or all of them are unsuccessful, the display unit will give a prompt and an error message.
[0027] (2) Reading step: the mobile p...

The invention discloses an identity verification method for a mobile terminal based on speech recognition, and is characterized in that the method comprises the following steps that: (1) a reference audio sample taken as a template is obtained and subject to audio parameterization to generate a reference vector tree and a reference bar chart; (2) a current audio sample is obtained and subject to an audio parameterization to generate a current vector tree and a current bar chart; (3) the templates are compared: the distance between the reference bar chart and the current bar chart is calculated according to a distance calculation method; (4) the obtained distance and a preset threshold are compared to obtain a final judgment conclusion; (5) an identity verification is finished. The method makes identity verification according to the human audio characteristics, has high reliability as well as simple and convenient implementation.
Description
technical field [0001] The invention relates to an identity verification method, in particular to a speech recognition-based identity verification method for a mobile terminal. Background technique [0002] Mobile phones (and other mobile terminal devices), as wireless mobile communication terminal devices, have become an important part of people's daily work, study and life. Basic mobile phone functions such as voice calls, text messages, MMS, and color ring tones have been widely promoted and used. . As the functions of mobile phones become stronger and more perfect, many applications based on wired networks will gradually transition to wireless networks. Medium and high-end mobile phones will provide various services for mobile commerce, bringing new and greater demands for mobile communications. , At the same time, it also puts forward higher requirements for the security performance of mobile phones such as identity verification. In business activities, identification...
