specifically, the user invokes his control interface by inputting the specified speech content, for example, the input sentence may be: please open my control interface; or please display my source screen; or ask for my display content, etc.
in practical implementation, since different persons have different timbres, even if the same speech is spoken by different persons, the recognized acoustic features are different, and the acoustic features of different persons are obviously different. The acoustic feature recognition is actually recognition of voiceprints, and based on acoustic features, sounds made by different users can be recognized, so that the identity of the user who inputs the voice currently can be determined. The basic steps of acoustic feature recognition are: the input speech is converted into speech parameters such as gene periods, linear prediction coefficients, vocal tract impulse responses, vocal tract area functions, perceptual linear prediction coefficients, etc.
specifically, after determining the acoustic features of the current input voice, the acoustic features of the current input voice are compared with acoustic features of different users pre-stored in a database to find out matched acoustic features, and user information and user permissions corresponding to the acoustic features are determined.
specifically, the control host generates a control interface of the current user based on the determined user information and the user authority. The user authority mainly refers to: and the user has an image source list of the release authority. Thumbnails of the respective image sources are displayed according to the list.
Specifically, the delivery request includes, but is not limited to: a release request for releasing a certain path of picture to which virtual position; or ending the request of which releasing path; or, a request back to the main display interface; the user may initiate the release request through different statements, for example, if the user wants to release the image 3 to the position 1, it can be said that: please drop image 3 to position 1.
After receiving a sentence input by a user, performing semantic recognition on the sentence, determining operation content corresponding to the sentence, and then executing corresponding operation. For example, if it is determined through semantic recognition that the user wishes to project the image 3 to the location 1, the receiving software receiving the image 3 outputs the corresponding image to the remote control screen corresponding to the location 1 through the corresponding video card port for display.
According to the scheme, in the release control process, the identity of the user initiating the voice control does not need to be identified, namely, anyone can use a correct control statement to realize the voice control.
In an alternative embodiment, it may be specified that voice control can only be performed by the current user when the control interface of the current user is displayed, at this time, the current user is determined as an authorized user, when the user inputs a control statement, it is first required to determine whether the current statement is from the authorized user based on recognition of acoustic features, if not, the current user is notified that there is no control authority, if so, semantic recognition is continued, and the content of an operation initiated by the user is determined based on a semantic recognition result, so as to perform a corresponding operation.
The method comprises the steps of marking a current user as an authority user, receiving a release request initiated by the user through voice, carrying out acoustic feature recognition on the received release request, and determining whether the recognized acoustic feature is matched with the current authority user.
In the semantic recognition process, if the corresponding operation content cannot be determined according to the semantic recognition result, prompt information that the voice cannot be correctly recognized needs to be returned to the user, and the prompt mode includes but is not limited to: speech, text messages, pictures, flashing of indicator lights, lighting, color changes, etc.
