Description

technical field [0001] The invention relates to the field of electronics, in particular to the field of digital signal processing, in particular to the application of a neural network voice non-contact recognition technology, in particular to a mobile phone voice key. Background technique [0002] At present, the traditional unlocking methods are still adopted in the operating systems of mobile phones on the market, namely combination key unlocking and password (PIN code) unlocking. Not only is the procedure cumbersome to operate, but it is also very unsafe. For example, when the mobile phone is lost, the password is leaked, etc., the information, data, and even privacy stored in the mobile phone are in danger of being leaked, embezzled, or even peeped. Contents of the invention [0003] The technical problem to be solved by the present invention is: the current unlocking of mobile phones mainly adopts combination key unlocking or password unlocking technology. These two ...
