Embodiments of the present disclosure provide a language recognition method and apparatus, a device and a computer storage medium. In an aspect, in the embodiments of the present disclosure, after the Nth speech segment included by the speech signal is received, language recognition is performed according to already-received previous N speech segments to obtain the score of each language in at least one language, N being 2, 3, 4 . . . ; therefore, if there exists a langue whose score reaches the designated threshold, the language whose score reaches the designated threshold is considered as the language matched with the speech signal. Therefore, the technical solutions according to embodiments of the present disclosure solve the problem in the prior art that the efficiency of language recognition is lower so that the language recognition cannot be applied to an application scenario in which the recognition result needs to be obtained quickly.

Disclosed is a voiceprint login method based on artificial intelligence. The method includes: S1: receiving a login request from a user and acquiring user information of the user; S2: generating a login string and replacing at least one character of the login string according to character replacement reference information corresponding to the user information; S3: providing the login string after replacement to the user and receiving speech information of the user reading the login string; and S4: performing a login authentication on the user according to speech information of the user reading the login string. With the method, by using the voiceprint authentication method combining the voiceprint and the character replacement reference information set by the user, the safety of the voiceprint password is increased, and some characters are hidden according the user's preferences, which satisfies the user's psychological demand of not wishing the password to be displayed explicitly.

The present invention discloses a voiceprint verification method, apparatus, storage medium and device. The method includes the following steps: generating and displaying, by a client terminal, random identifiers of various keyboard elements having fixed identifiers, so as to enable a user to set a password by inputting a voice signal of the random identifier of at least one of the keyboard elements (); and receiving, by the client terminal, a first voice signal input when the user sets the password, and transmitting the first voice signal to a server (); receiving, by a server, a first voice signal which is input when a user sets a password and forwarded by a client terminal; extracting, by the server, at least one random identifier from the first voice signal, wherein each of the random identifiers respectively corresponds to a keyboard element having a fixed identifier; and determining, by the server, the respective fixed identifiers of the keyboard elements corresponding to the various extracted random identifiers, and determining and storing the password set by the user according to the determined fixed identifiers. By means of the above mentioned method, the problem in the prior art that a fixed password is visible is avoided, thereby improving the security.

A method for using an extending super-frame to transfer data in a short distance wireless personal network is provided. Firstly, the super-frame segments, which are in an active period of a network coordinator are continuously copied to a whole inactive period of a current device, and an extending super-frame segments are obtained. Then, information is broadcasted to all general devices. The general device with a quality of service requirement send a service guarantee time slot bandwidth application to the network coordinator, and indicates in the application that the extending super-frame is required. When the application is granted, the super-frame segments, which are in the active period of the current device are copied to the whole inactive period, and the extending super-frame segments are obtained. Then, data is transmitted to the network coordinator with the extending super-frame segments.

A ranging method is described for measuring distance between a central node and an equipment node in a beacon wireless personal area network. At the beginning stage, the central node calculates the parameters needed in the ranging operation and sends these parameters to the equipment nodes by beacon frames. Equipment nodes, in turn, send ranging frames at time slots assigned thereto according to the information received in the beacon frames. The central node calculates beacon frame flight time by recording the sending time and the arrival time of the ranging frame, and then calculates the distance between the central node and the equipment node. For nodes failing in the ranging procedure, the ranging parameters are changed according to failing reasons and the above procedure is repeated until a ranging result is received without failure.
