Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a voice conference recording method according to an embodiment of the present invention, which includes the following steps:
s11: establishing websocket connection for the mobile phone client, the recording device and the conference synchronization end, and sending a conference sharing link to the conference synchronization end through the websocket connection, wherein the conference sharing link is used for the conference synchronization end to enter a synchronous conference sharing interface;
s12: the recording equipment responds to a conference recording instruction sent by a mobile phone client, collects conference audio in real time, uploads the conference audio to a cloud identification service, and receives conference characters fed back by the cloud in real time;
s13: the recording equipment synchronously transmits the meeting characters to meeting sharing interfaces of the mobile phone client and the meeting synchronous end through the websocket connection;
s14: synchronizing the conference characters modified by the mobile phone client and/or the conference sharing interface in real time through a cooperative operation conversion (OT) algorithm so as to realize that one end is modified and the other end coordinates the modified content in real time;
s15: and generating a conference recording file from the modified conference characters for sharing the conference content when the conference ending instruction is sent by the mobile phone client.
In this embodiment, a dedicated recording device is configured for the audio recording effect, and the recording device collects the audio by using dedicated hardware for collecting the audio and matching with the annular microphone and the gain algorithm. Through the specific customer end of cell-phone end installation, with exclusive recording equipment pairs, for example, pairs through the bluetooth, is connected to recording equipment back at mobile phone bluetooth, and the personnel are recorded in the meeting clicks through the APP in the cell-phone and begins the meeting and record, perhaps can directly press the recording entity button on the recording equipment. At this point, voice conference recording is initiated.
For step S11, a websocket connection is established for the mobile phone client, the recording device, and the conference synchronization end, where the conference synchronization end is a common device used by the participating personnel, such as a computer. And after establishing the websocket connection, sending a conference sharing link to the conference synchronization terminal of the participant. Therefore, the conference synchronous terminal can enter the conference sharing interface only through the sharing link, and can enter the conference only by a little without other operations of the participators.
For step S12, the recording device responds to the conference recording instruction sent by the mobile phone client, collects the audio of the conference in real time, uploads the audio of the conference to the cloud recognition service through the network, and because the recording device is special hardware for collecting the audio, the cloud recognition effect is better, and after the cloud is transcribed, the conference text fed back by the cloud is received in real time.
For step S13, after the recording device receives the meeting text fed back by the cloud in real time, the meeting text is synchronously sent to the mobile phone client held by the meeting recording staff and the meeting sharing interface of the meeting synchronization end of the meeting participant through the websocket connection established in step S11, so that sharing of the meeting text is realized.
For step S14, the mobile phone client and/or the conference text modified by the conference sharing interface are synchronized in real time through an Operation Transformation (OT) algorithm, which is applied in the field of collaborative editing more often. Taking the collaborative editing as an example, the OT may understand that when a conference recorder modifies a character in a conference sharing interface, another participant happens to modify the character, and a conflict is generated at this time, and at this time, an operation conversion needs to be performed on an input operation of the conference recorder to process an editing conflict with the other participant. And then realize one end and modify, another end cooperate with content changed, for example, the participant finds the meeting characters transcribed by the voice have errors, have modified, at this moment, with other personnel on the shared interface, will see the content modified too.
In step S15, after the meeting is finished, the meeting recording staff sends a meeting finishing instruction to the sound recording device through the mobile phone client, and generates a meeting recording file from the meeting text modified by each participant in the middle of the meeting, so as to share the meeting content.
According to the embodiment, by providing the conference sharing interface, the conference participants can conveniently join the conference sharing interface, the conference records are modified in real time through the conference sharing interface, the sharing operation is realized on the mobile client side and the conference synchronization side through the OT algorithm, and each conference participant can join the conference records. Meanwhile, special hardware for acquiring audio is adopted, so that the conference recording personnel can operate only by a prepared mobile phone, the audio with better quality can be recorded, and the accuracy of voice recognition and the experience of the participant in reviewing after the conference are improved.
As an implementation manner, in this embodiment, the mobile phone client and the conference sharing interface include: and the control button is used for controlling the playing, pausing and ending of the recording equipment through the websocket connection.
In this embodiment, the mobile phone client and the conference sharing interface further include a control button, and the recording device can be controlled to play, pause and end through the control button, for example, a middle-field rest time exists in a large conference, and the rest time does not need to be transcribed by voice.
According to the embodiment, the control buttons are provided on the mobile phone client and the conference sharing interface, so that conference recording personnel can conveniently perform corresponding processing aiming at various situations of a conference, and the using effect is improved.
As an implementation manner, in this embodiment, the meeting record file includes: and recording the meeting characters, the mobile phone client and/or the meeting sharing interface.
In this embodiment, the conference record file not only includes the conference text during the conference, but also stores the recording information of the mobile client and/or the conference sharing interface, including the information of modifying the record, adding the text record, and the like, and the conference review of the participants after the conference is finished can be facilitated through the recording information.
According to the embodiment, the conference review of the participants after the conference is finished is facilitated by providing other recording information except the conference characters in the conference recording file, and the use experience of the participants is improved.
In one embodiment, the conference synchronization end includes at least one synchronization device.
In this embodiment, the conference synchronization end at least includes one synchronization device, and since there is no only one participant, each participant can join in the conference sharing interface to perform the conference implementation cooperation.
According to the embodiment, the conference synchronization end can be a plurality of devices, so that the conference synchronization end is more in accordance with the scene of the conference, and the use experience of participants is improved.
