A response method and an apparatus thereof are provided. The method includes: receiving voice information sent through a client by a user; determining, based on the voice information, a user category to which the user belongs; and using voice matching the user category to respond to the voice information. Accordingly, response voice matches the user category of the user, which implements that the response is performed using the response voice targeted for the user category, and thus, the user experience may be improved.

Method and apparatus for response using voice matching user category

An apparatus for efficiently preparing spherical metal powder for 3D printing includes a housing, a crucible and a powder collection area arranged in the housing, wherein a turnplate arranged in the collection area is an inlaid structure. A material having a poor thermal conductivity is selected as the base of the turnplate, and a metal material having a wetting angle less than 90&#xb0; with respect to droplets is selected and embedded into the base to serve as an atomization plane of the turnplate. An air hole is disposed in the turnplate. The spherical metal powder for 3D printing combines electromagnetic force breaking capillary jet flow and centrifugal atomization, which breaks through the traditional metal split mode, and makes the molten metal in a fibrous splitting.

Device and method for high-efficiency preparation of spherical metal powder for 3D printing employing separation into fibers

An apparatus includes a housing, a crucible disposed in the housing, and a collection bin. A turnplate disposed in a powder collection area is of an inlaid structure. A concentric circular groove is provided on the atomization plane. An air hole is provided in the turnplate. The present invention combines the pulsated orifice ejection method and the centrifugal atomization method, in cooperation with the turnplate structure and subjecting the turnplate surface to induction heating, so that a metal liquid is allowed to break through the split mode of traditional molten metal, achieves a fibrous split mode that can be implemented only when an atomizing medium is an aqueous or organic solution, and prepares a high-melting-point metal powder that meets requirements, and has a controllable particle size, high sphericity, no satellite droplets, and good flowability and spreadability, and is suitable for industrial production.

The present disclosure provides a voiceprint recognition method and apparatus, comprising: according to an obtained command speech, recognizing, in a voiceprint recognition manner, a user class sending a command speech; according to the user class, using a corresponding speech recognition model to perform speech recognition for the command speech, to obtain a command described by the command speech; providing resources according to the user class and command. The present disclosure can avoid the problems that in a conventional voiceprint recognition method in the prior art, a client needs to participate in voiceprint recognition, and the user's ID needs to be further recognized through a voiceprint training process, and that the user's degree of satisfaction is not high. While the user speaks naturally, it is feasible to perform processing for these very 'ordinary' speech, and meanwhile complete the work of voiceprint recognition.

Voiceprint recognition method and apparatus

A method and apparatus for controlling a page are provided. A specific embodiment of the method comprises: receiving voice information sent by a terminal and inputted by a user from the terminal, where the terminal is used for displaying a target page and for receiving the voice information in response to receiving a voice control request for the target page from the user; recognizing voice from the voice information to generate text information; analyzing the text information to generate an operation instruction; and sending the operation instruction to the terminal to enable the terminal to execute an operation indicated by the operation instruction on the target page. The embodiment has realized voice-based page control.

A method and an apparatus for voiceprint creation and registration, comprising: prompting to create a voiceprint and register when a device is enabled for a first time(); using a text-related training method to create a voiceprint model for a user(); generating an ID for the user(); and prompting the user to input user ID-related data; storing the ID for the user and the voiceprint model correspondingly in a voiceprint registration database(). The problems in the prior art that the technology of the voiceprint creation and registration method has a high learning cost and is more disturbing to the user may be avoided. The voiceprint creation process may cover various scenes, the voiceprint creation may guide the user in all stages, or the voiceprint creation is separated from registration through a frequency to minimize user's disturbance, and after the user is guided to register the voiceprint, the speech interaction product may provide personalized service to the user based on the voiceprint.
