Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The conference picture switching device based on voice recognition according to the preferred embodiment of the present invention comprises: the device comprises a voice recognition library generation module, a voice recognition module, a semantic analysis module and a picture switching module. The voice recognition library generating module generates a voice recognition library based on the sign-in information and the platform address book information; the voice recognition module carries out conference voice recognition based on the voice recognition library so as to find a matching result; the semantic analysis module is used for performing semantic analysis on the matching result of the voice recognition module; and the picture switching module is used for switching pictures according to the semantic analysis result.
As shown in fig. 1, the main flow of the switching method of the conference picture switching apparatus based on voice recognition according to the preferred embodiment of the present invention is as follows: and (3) voice recognition name-the terminal (or the conference room system) corresponding to the matched name-switching the camera picture of the corresponding terminal (or the conference room system). The method specifically comprises the following steps:
firstly, generating a voice recognition library based on sign-in information and platform address book information;
the steps mainly relate to platform address book and sign-in function. Wherein, platform address book information includes: names and nicknames of the participants and remark names of the participants. The acquisition mode of the check-in information comprises the following steps: the system comprises face recognition, manual check-in, card swiping check-in and terminal automatic check-in, and is used for determining information such as presence members of a conference room, a place where the conference room is located and the like. The conference picture switching method combines the information to form a voice recognition library and a query table.
Secondly, conference voice recognition is carried out based on a voice recognition library so as to find a matching result;
for example: "… … the next time is handed to Zhang III, 'Zhang III' (i.e., the call process where a match is found)".
Thirdly, performing semantic analysis on the matching result;
semantic analysis means to analyze whether a main sentence calls a person, talks about a person or commands an operation; if the semantic is determined to be the call instruction, finding the appointed meeting place according to the query table, and switching the pictures. For example: "… … the next time is handed to Zhang III, 'Zhang III', two 'Zhang III' appeared in the former words, both will be recognized in the speech recognition, because of recognizing the name, both will be lost to the semantic analysis step for analysis, according to the pause time before and after, the coherence, or the prior art means to analyze whether it is the call instruction. In the conference process, the switching is not sensed (for example, Zhang III wants to make the Li IV send an opinion, only the Li IV needs to be said, and what you have is seen, at this moment, the picture is switched to the picture of the Li IV, and then everybody can see the video picture of the Li IV to wait for the answer of the Li IV, so that the real experience of face-to-face meeting is better). And the conference picture switching method based on the voice recognition is added with a semantic recognition function, so that not only can accurate judgment be carried out on participants who the user wants to watch, but also specific voice operation (command operation) can be added, such as switching to a Beijing conference place.
And finally, switching pictures according to the semantic analysis result.
Switching screens based on a display policy (for example, directly switching screens in the case of a single window, switching screens in the case of multiple windows, switching screens in a large window, switching screens in a window arranged at the top in the case of a large window, etc.), for example: zhang III can sign in meeting room 1, and at the same time, a notebook computer and a mobile phone are used in meeting room 1 to carry out a meeting, at the moment, more than two cameras are all aligned to Zhang III, such as meeting room 1 system cameras (more than 2 cameras can be used in a meeting room system) and notebook terminal cameras. In this case, there may be a priority algorithm, such as a priority display in which the image person ratio is large (the upper face is certainly the notebook terminal camera), and if the ratio is about large, a priority display in the front face, etc. The method can also be matched with the voice excitation mode to select the method with short pickup distance.
In conclusion, the conference picture switching method based on the voice recognition integrates the sign-in information and the address book information into the voice recognition library, so that the conference picture switching is more intelligent, and the real experience of face-to-face meeting is achieved. And the semantic recognition function is added, so that the accurate judgment can be performed on the participants the user wants to watch, the specific voice operation can be added, and the conference experience is improved.
