[0059] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0060] The embodiment of the present application provides a method for intelligent release of a conference room. The execution subject of the intelligent release method of the conference room includes but is not limited to at least one of the electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiment of the present application. In other words, the intelligent release method of the conference room can be executed by software or hardware installed on a terminal device or a server device, and the software can be a blockchain platform. The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc. The server can be an independent server, or it can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), and big data and artificial intelligence platforms.

[0061] Reference Figure 1 FIG. 1 is a flow chart of an intelligent release method for a conference room provided by an embodiment of the present invention. In this embodiment, the intelligent release method for a conference room includes:

[0062] S1. When it is detected that the scheduled time of the conference room has arrived, the voice monitoring device in the conference room is turned on.

[0063] In an embodiment of the present invention, the voice monitoring device can be a microphone installed in the conference room, which can capture all sounds in and outside the conference room. In addition, in an embodiment of the present invention, the voice monitoring device is connected to a pre-built conference room management cloud. When the time reaches the reserved time of the conference room, the voice monitoring device is automatically turned on through a preset collaborative service. Among them, the conference room management cloud is a backend server for managing conference rooms, which can arrange and manage conference rooms according to reservation requests sent by users through mobile phone apps, WeChat applets or terminal platforms.

[0064] S2. Acquire the audio data of the conference room using the voice monitoring device.

[0065] Detailed, such as Figure 2 As shown, in the embodiment of the present invention, the method of obtaining the audio data of the conference room by using the voice monitoring device includes:

[0066] S21, using the preset embedding point to obtain the electrical signal from the target speaker in the conference room;

[0067] S22, using the voice monitoring device to monitor the sound in the conference room to obtain the conference room audio;

[0068] S23. Using a pre-built filter, perform similarity filtering on the conference room audio according to the electrical signal to obtain audio data.

[0069] In the embodiment of the present invention, the embedding point can be configured in the speaker plug-in of the computer to monitor the electrical signals of all sounds that can be emitted by the speaker.

[0070] Specifically, in an embodiment of the present invention, the characteristics of the electrical signal transmitted from the computer speaker are recorded by using the embedding point. When acquiring the conference room audio, a filter can be used to filter the signal in the conference room audio that is similar to the characteristics of the electrical signal to obtain local audio data in the conference room.

[0071] The embodiment of the present invention performs similarity filtering on the conference room audio through the electrical signal in the speaker, and can shield the voice data sent by the video of the conference connection in the conference room.

[0072] S3. Determine, based on the audio data, whether there is human voice in the conference room within a preset time period.

[0073] In the embodiment of the present invention, the human voice refers to the sound of a person speaking. In addition, the embodiment of the present invention sets the time period to ten minutes.

[0074] In one embodiment of the present invention, judging whether there is human voice in the conference room within a preset time period according to the audio data includes:

[0075] Recognize the audio data using a pre-trained sound recognition model to obtain a scoring score of whether the audio data belongs to a human voice;

[0076] Determine whether the scoring score is greater than a preset qualification threshold;

[0077] When the scoring score is greater than the qualified threshold, it is determined that there is a human voice in the audio data;

[0078] When the scoring score is less than or equal to the qualified threshold, it is determined that there is no human voice in the audio data.

[0079] Among them, the sound recognition model is a regression model based on a convolutional neural network, which can recognize various common sounds in the audio data, such as human voices, car horns, dog barking, wood sawing and other sounds.

[0080] In the embodiment of the present invention, since the sound in the conference room mainly comes from the sound of people speaking, after the present invention obtains a sound recognition model, the sound recognition model is specifically trained through pre-constructed voice samples of the human voice category to increase the accuracy of recognizing the human voice.

[0081] In the embodiment of the present invention, by configuring the qualified threshold of 70%, the scoring score of the recognized human voice category is restricted, and only when the scoring score is greater than 70%, it can be determined that there is human voice in the audio data.

[0082] If there is no voice in the conference room within the time period, the conference room is released.

[0083] In order to prevent a conference room from being reserved but not occupied, the embodiment of the present invention can automatically release the conference room when there is no voice in the conference room within a preset time period.

[0084] Preferably, when there is no voice in the conference room within the time period, another embodiment of the present invention can remind the reserved persons in the conference room by confirmation, urging, etc. through a text message platform, and when there is still no voice in the conference room within a second time period, a release instruction is generated to release the conference room.

[0085] If there is a human voice in the conference room within the time period, then S4, voice recognition is performed on the human voice, and it is determined whether there is a preset release keyword in the voice recognition result.

[0086] Specifically, in an embodiment of the present invention, the performing speech recognition on the human voice and determining whether there is a preset release keyword in the speech recognition result includes:

[0087] Performing noise reduction processing on the audio data to obtain noise reduction data;

[0088] Using a pre-built speech-to-text tool to recognize the noise reduction data to obtain a sentence text;

[0089] Using a pre-built semantic recognition model, semantic analysis is performed on the sentence text to obtain a similarity between the sentence text and a preset release keyword;

[0090] When there is a sentence in the sentence text whose similarity with the preset release keyword is greater than a preset similarity threshold, it is determined that the sentence text contains the preset release keyword.

[0091] Specifically, the embodiments of the present invention can filter the environmental noise such as the movement of tables and chairs and walking in the audio data through a filter to increase the accuracy of speech-to-text conversion; and use any existing speech conversion technology to convert the audio data into sentence text, and after obtaining the text sentence, use the database retrieval function to check whether the sentence text contains preset release keywords, such as "end of meeting", "release meeting room", etc., by querying keywords.

[0092] In addition, in order to increase the recognizability of the sentence text and relax the recognition requirements, when the sentence text does not contain the release keyword, another embodiment of the present invention can use the local training set to pre-train the pre-built semantic recognition model, and after obtaining the semantic recognition model adapted to the call meaning of the conference room scene, the trained semantic recognition model is used to identify whether the sentence text contains the semantics of releasing the conference room. Among them, the semantic recognition model is a text recognition model based on the BERT convolutional neural network, which is used to extract content features in the text and combine the features to obtain the text expression semantics.

[0093] The embodiment of the present invention determines the similarity score between the sentence text and the release keyword. If the score is greater than a preset similarity threshold, such as 95%, the sentence can be considered equivalent to the release keyword, and it is determined that the sentence text contains the preset release keyword.

[0094] Furthermore, if Figure 3 As shown, in the embodiment of the present invention, the semantic analysis of the sentence text is performed using a pre-built semantic recognition model to obtain the similarity between the sentence text and the preset release keyword, including:

[0095] S41, using a pre-built word segmentation tool to perform word segmentation processing on the sentence text to obtain a word set;

[0096] S42, quantizing the word set using a pre-built word2Vec model to obtain a word vector set;

[0097] S43, encoding the word vector set using a preset position code to obtain a sequential quantization result;

[0098] S44, using the semantic recognition model to perform feature extraction calculation on the sequential quantization result to obtain a feature sequence;

[0099] S45, importing the feature sequence into the fully connected layer of the semantic recognition model to obtain the similarity between the feature sequence and each preset release keyword.

[0100] The embodiment of the present invention can use the pre-built jieba word segmentation tool to segment the word set to obtain the word set.

[0101] In addition, although the word2vec model is a group of related models used to generate word vectors, the generated word vectors are discrete and disordered. A sentence text will be quantized into [E 就 、E 今天 、E 说 、E 这 、E 到 、E 散 、E 会 】. The embodiment of the present invention uses a preset position code such as [intra-sentence code: E 0 、E 1 ……】 and

Extra-sentence coding: E A 、E B ……], sort the word vector set, and get [E A +E 0 +E 今天 、E A +E 1 +E 就 、E A +E 2 +E 说 、E A +E 3 +E 到 、E A +E 4 +E 这 、E B +E 0 +E 散 、E B +E 1 +E 会

[0102] Furthermore, the embodiment of the present invention uses the BERT attention mechanism in the semantic recognition model to configure the weights of each quantization result, performs a feature extraction operation, obtains a feature sequence, and recognizes the feature sequence set through the fully connected layer of the semantic recognition model.

[0103] When the voice recognition result contains a preset release keyword, step S4 is executed to release the conference room.

[0104] In the embodiment of the present invention, the semantic recognition model is used to identify that the similarity between "That's all for today, the meeting is adjourned" and the preset release keyword "release the conference room" is about 85%. If it is greater than 80%, "release the conference room" will replace the sentence text of "That's all for today, the meeting is adjourned". If the judgment result is that the release keyword exists in the sentence text, the conference room will be released.

[0105] Furthermore, when the release keyword exists in the sentence text, it indicates that the user has ended the meeting and can release the conference room. In another embodiment of the present invention, due to the presence of some cleanup work, this scheme can set a delay time, that is, starting from the presence of a preset release keyword in the voice recognition result, the conference room is released after a preset third time period, such as ten minutes.

[0106] When the preset release keyword does not exist in the speech recognition result, S5, determining whether the reservation time of the conference room has ended.

[0107] In an embodiment of the present invention, if there is no preset release keyword in the speech recognition result, the conference room management cloud can be queried to obtain the reserved usage time of the conference room, and then the local timestamp can be extracted to check whether the reserved time has ended.

[0108] When the reservation time of the conference room ends, releasing the conference room;

[0109] When the reservation time of the conference room has not ended, the process returns to the above step S2, and the audio data of the conference room is acquired by using the voice monitoring device.

[0110] Specifically, in the embodiment of the present invention, when the reservation time in the conference room has not arrived and the release keyword is not detected, the process may return to S2 and continuously acquire the audio data of the conference room by using the voice monitoring device.

[0111] In another embodiment of the present invention, when the reservation time in the conference room has not arrived and the release keyword is not detected, the process may return to S2 after a preset fourth time period, such as ten minutes, to save system resources.

[0112] In addition, another embodiment of the present invention can install a display screen outside the conference room to prompt the use status of the conference room. Furthermore, the display screen can also have a voice recognition function and / or a manual release function, so that cleaning staff or other people who want to use the conference room can quickly release the conference room when they find that there is no one in the conference room.

[0113] In detail, in another embodiment of the present invention, after detecting that the scheduled time of the conference room has arrived and turning on the voice monitoring device, the method further includes:

[0114] The display screen outside the conference room is controlled to display that the conference room is in use.

[0115] Furthermore, in order to ensure that the cleaning staff or other people who want to use the conference room can quickly release the conference room when they find that no one is in the conference room, an embodiment of the present invention builds a display screen outside the conference room to display and control the conference room status. In addition, in order to ensure that when people outside the conference room release the conference room, there is really no one in the conference room, another embodiment of the present invention may also include:

[0116] Monitoring audio data outside the conference room using a speech recognition component outside the conference room;

[0117] When the audio data outside the conference room contains the preset release keyword, determining whether there is a human voice in the audio data in the conference room currently acquired by the voice monitoring device in the conference room;

[0118] When there is a human voice in the audio data in the conference room, it is prompted that the conference room is occupied by someone;

[0119] When there is no voice in the audio data in the conference room, the conference room is released.

[0120] Therefore, when people outside the conference room release the conference room, the conference room can be released if there is no sound inside the conference room. The conference room cannot be released if there are still people using the conference room.

[0121] The embodiment of the present invention uses voice recognition to determine whether a release keyword is present in the conference room to release the conference room. Manual release is not required. The conference room can be quickly released in an intelligent manner to avoid invalid occupation of the conference room, thereby increasing the efficiency of conference room use. Therefore, the intelligent conference room release method of the present invention can solve the problem of conference room resource shortage caused by failure to release the conference room in time.

[0122] like Figure 4 , which is a functional module diagram of an intelligent release device for a conference room provided by an embodiment of the present invention.

[0123] The intelligent release device 100 for a conference room of the present invention can be installed in an electronic device.

The module of the present invention can also be referred to as a unit, which refers to a series of computer program segments that can be executed by a processor of an electronic device and can complete fixed functions, and is stored in the memory of the electronic device.

[0124] In this embodiment, the functions of each module / unit are as follows:

[0125] The audio monitoring module 101 is used to turn on the voice monitoring device in the conference room when the scheduled time of the conference room is detected, and use the voice monitoring device to obtain the audio data of the conference room;

[0126] The scene determination module 102 is used to determine whether there is human voice in the conference room within a preset time period according to the audio data, and release the conference room if there is no human voice in the conference room within the time period;

[0127] The instruction recognition module 103 is used to perform speech recognition on the human voice if there is a human voice in the conference room within the time period, and determine whether there is a preset release keyword in the speech recognition result;

[0128] The conference room releasing module 104 is used to release the conference room when a preset release keyword exists in the voice recognition result, and to determine whether the reservation time of the conference room has ended when the preset release keyword does not exist in the voice recognition result, and to return to the above-mentioned step of obtaining the audio data of the conference room by using the voice monitoring device when the reservation time of the conference room has not ended, and to release the conference room when the reservation time of the conference room has ended.
