Description

Online conference sound self-excitation elimination method, device, equipment and storage medium

技术领域Technical field

本公开涉及在线视频通话技术领域，尤其涉及一种在线会议声音自激消除方法、装置、设备及存储介质。The present disclosure relates to the technical field of online video calls, and in particular, to an online conference sound self-excitation elimination method, device, equipment and storage medium.

背景技术Background technique

在线多人会议是指位于两个或多个地点的人们，通过笔记本电脑、智能手机等会议终端设备，进行在线沟通。根据参会地点数目不同，视频会议可分为点对点会议和多点会议。随着5G新通话的发展，在线多人会议可以在视频会议中融入智能翻译、趣味通话、智能客服、多屏通话、内容分享、远程协助等功能，大大增加了在线多人会议的便捷性和乐趣。Online multi-person meetings refer to people in two or more locations communicating online through laptops, smartphones and other conference terminal devices. Depending on the number of participating locations, video conferences can be divided into point-to-point conferences and multi-point conferences. With the development of new 5G calls, online multi-person meetings can incorporate functions such as intelligent translation, fun calls, intelligent customer service, multi-screen calls, content sharing, and remote assistance into video meetings, greatly increasing the convenience and convenience of online multi-person meetings. pleasure.

在实际的会议场景中，某个会议接入点会有多台会议终端设备，比如A会议室的若干名参会人员每人携带一台笔记本电脑和位于异地的B会议室的人员参加在线会议，A会议室的每个参会人员都可以通过观看自己的笔记本电脑屏幕查看PPT等画面内容，同时可以通过扬声器听取别人的发言，并且每个参会人员都可以即时发言，笔记本的声音接收器接收到发言后，通过网络将发言内容发送至其他参会人员。由于A会议室有多台笔记本电脑，每台笔记本电脑都有扬声器和声音接收器。如果多台笔记本电脑都打开了扬声器和声音接收器，声音很容易在各个电脑间产生震荡回声，一个声音从一台笔记本电脑扬声器发出，又进入另一台笔记本声音接收器，信号又经过网络，回到开始的笔记本电脑，使得笔记本电脑扬声器又重复发出该声音，如此循环，形成回声，回声频率逐渐提高，最终形成刺耳的声音，这种现象也叫做声音自激。In an actual conference scenario, a conference access point will have multiple conference terminal devices. For example, several participants in conference room A each bring a laptop computer to participate in an online conference with people in conference room B located in another place. , each participant in meeting room A can view PPT and other screen content by watching his or her own laptop screen, and at the same time listen to other people's speeches through the speakers, and each participant can speak instantly with the laptop's sound receiver After receiving the speech, the speech content is sent to other participants through the network. Since there are multiple laptops in Conference Room A, each laptop has a speaker and sound receiver. If multiple laptops have their speakers and sound receivers turned on, the sound can easily produce oscillation echoes between the computers. A sound comes from the speakers of one laptop and enters the sound receiver of another laptop. The signal then passes through the network. Returning to the laptop computer at the beginning, the laptop speaker repeatedly emits the sound. This cycle forms an echo, and the frequency of the echo gradually increases, eventually forming a harsh sound. This phenomenon is also called sound self-excitation.

目前，参会人员往往需要手动关闭一台或多台笔记本电脑的扬声器以及声音接收器来消除声音自激，声音自激消除效率低，用户体验较差。At present, conference participants often need to manually turn off the speakers and sound receivers of one or more laptops to eliminate sound self-excitation. The sound self-excitation cancellation efficiency is low and the user experience is poor.

For example, when a participant enters the conference, the server detects the IP address of the conference terminal of the participant who is accessing the online conference. The administrative region corresponding to the IP address is Beijing, and the conference access point name is automatically selected as the Beijing venue for the participant. .

在上述实施例中，参会人员可以使用参会终端查看自己的会议接入点，在会议接入点信息错误时，可通过参会终端对自己的会议接入点进行修改。一种可实现的方式为，会议终端响应于接入点修改操作，将原始会议接入点进行修改得到的接入点，提高会议接入点的准确率，提升用户体验。In the above embodiment, participants can use the participant terminal to check their own conference access point. When the conference access point information is incorrect, they can modify their own conference access point through the participant terminal. One possible way is that the conference terminal responds to the access point modification operation and modifies the original conference access point to obtain an access point, thereby improving the accuracy of the conference access point and improving user experience.

需要说明的是，上述映射关系表的具体形式可以为参会人员、参会终端和会议接入点之间的映射关系表。例如，参会人员名称、参会终端设备型号和会议接入点名称的映射关系表。It should be noted that the specific form of the above mapping relationship table may be a mapping relationship table between conference participants, conference terminals and conference access points. For example, the mapping relationship table between participant names, participant terminal device models, and conference access point names.

在线会议发生声音自激时，一个声音从一台会议终端设备扬声器发出，又进入另一台会议终端设备声音接收器，信号又经过网络，回到开始的会议终端设备，使得会议终端设备扬声器又重复发出该声音，如此循环，形成回声，并且重复频率逐步加快，最终形成尖锐刺耳的声音，无法辨别声音的内容，尖锐刺耳的声音持续一段时间后，自激声音开始衰减。根据此特性，将声音自激划分为自激回声期、自激尖锐期、自激衰减期。自激回声期是指一个声音不断啊重复播放的阶段，自激尖锐期是指形成尖锐刺耳的声音的阶段，自激衰减期是指自激声音开始衰减直到自激消失的阶段。When sound self-excitation occurs in an online conference, a sound is emitted from the speaker of one conference terminal equipment and enters the sound receiver of another conference terminal equipment. The signal passes through the network and returns to the starting conference terminal equipment, causing the speaker of the conference terminal equipment to return to the original conference terminal equipment. The sound is repeatedly emitted, and the cycle is repeated to form an echo, and the repetition frequency is gradually accelerated, eventually forming a sharp and harsh sound, and the content of the sound cannot be identified. After the sharp and harsh sound continues for a period of time, the self-excited sound begins to decay. According to this characteristic, sound self-excitation is divided into self-excited echo period, self-excited sharp period, and self-excited decay period. The self-excited echo period refers to the stage in which a sound is played repeatedly, the self-excited sharp stage refers to the stage in which a sharp and harsh sound is formed, and the self-excited decay period refers to the stage in which the self-excited sound begins to decay until the self-excited disappears.

在本公开的一些实施例中，根据监测到的声音信号，确定在线会议是否发生声音自激，包括以下至少一种确定方式：In some embodiments of the present disclosure, determining whether sound self-excitation occurs in an online conference based on the monitored sound signal includes at least one of the following determination methods:

确定方式一，根据监测到的声音信号，统计声音信号中的目标声音的次数；在次数大于次数阈值的情况下，确定在线会议发生声音自激。需要说明的是，本公开实施例对次数阈值不作限定，次数阈值可以根据实际情况作出调整。例如，服务器实时监测声音信号，当某一段声音信号重复次数大于次数阈值时，则判断发生声音自激。比如，当参会人员说出“开始开会”，“开始开会”的声音在同一台设备中连续重复次数超过3次，判断发生声音自激。该实施方式可以适用于自激回声期实现系统判断是否发生声音自激。The first determination method is to count the number of target sounds in the sound signal according to the monitored sound signal; when the number is greater than the number threshold, it is determined that sound self-excitation occurs in the online conference. It should be noted that the embodiment of the present disclosure does not limit the number of times threshold, and the number of times threshold can be adjusted according to the actual situation. For example, the server monitors the sound signal in real time. When the number of repetitions of a certain sound signal is greater than the number threshold, it is judged that sound self-excitation has occurred. For example, when a participant says "start the meeting" and the sound of "start the meeting" is repeated more than three times in a row on the same device, it is judged that sound self-excitation has occurred. This embodiment can be applied to the self-excited echo period to realize the system's determination of whether sound self-excitation occurs.

确定方式二，根据监测到的声音信号，统计第一时间段内的声音信号功率；在声音信号功率大于功率阈值的情况下，确定在线会议发生声音自激。需要说明的是，本公开实施例对功率阈值不作限定，功率阈值可以根据实际情况作出调整。例如，服务器实时监测声音信号功率，当检测到某个时间段内声音信号功率超过功率阈值，判断发生声音自激。该实施方式可以适用于自激尖锐期实现系统判断是否发生声音自激。The second determination method is to count the sound signal power in the first time period based on the monitored sound signal; when the sound signal power is greater than the power threshold, it is determined that sound self-excitation occurs in the online conference. It should be noted that the embodiments of the present disclosure do not limit the power threshold, and the power threshold can be adjusted according to actual conditions. For example, the server monitors the sound signal power in real time. When it detects that the sound signal power exceeds the power threshold within a certain period of time, it determines that sound self-excitation has occurred. This embodiment can be applied to the sharp period of self-excitation to enable the system to determine whether sound self-excitation occurs.

确定方式三，接收会议终端上传的发生声音自激信息；根据发生声音自激信息，确定在线会议发生声音自激。例如，参会人员发现发生声音自激，手动点击上报相关功能键，手动向系统上报发生声音自激，系统收到参会人员上报信息后，判断发生声音自激。该实施方式可以适用于自激回声期、自激尖锐期和自激衰减期实现系统判断是否发生声音自激。The third determination method is to receive the self-excited sound information uploaded by the conference terminal; determine the self-excited sound in the online conference based on the self-excited sound information. For example, if a participant discovers that sound self-excitation occurs, he or she manually clicks the relevant function button to report the occurrence of sound self-excitation to the system. After receiving the information reported by the participant, the system determines that sound self-excitation has occurred. This implementation mode can be applied to the self-excited echo period, self-excited sharp period and self-excited decay period to realize the system's judgment of whether sound self-excitation occurs.

在本公开的一些实施例中，在确定在线会议发生声音自激的情况下，获取参会人员与会议接入点的映射关系表，根据映射关系表，可以确定每个参会人员对应的会议接入点。In some embodiments of the present disclosure, when it is determined that sound self-excitation occurs in an online conference, a mapping relationship table between participants and conference access points is obtained. According to the mapping relationship table, the conference corresponding to each participant can be determined. Access Point.

图2为本公开示例性实施例提供的一种确定参会人员是否处于发言状态方法的流程示意图。如图2所示，该方法包括：FIG. 2 is a schematic flowchart of a method for determining whether a participant is in a speaking state provided by an exemplary embodiment of the present disclosure. As shown in Figure 2, the method includes:

S201：根据目标会议接入点，查询映射关系表，得到目标会议接入点对应的参会人员；S201: According to the target conference access point, query the mapping relationship table to obtain the participants corresponding to the target conference access point;

S202：监测目标会议接入点对应的参会人员的会议终端在第二时间段内的目标声音信号；S202: Monitor the target sound signal of the conference terminal of the participant corresponding to the target conference access point in the second time period;

S203：根据目标声音信号，确定目标会议接入点对应的参会人员是否处于发言状态。S203: Determine whether the participant corresponding to the target conference access point is in a speaking state according to the target sound signal.

需要说明的是，本公开对第一时间段和第二时间段不作限定，第一时间段和第二时间段可以根据实际情况作出调整。It should be noted that the present disclosure does not limit the first time period and the second time period, and the first time period and the second time period can be adjusted according to actual conditions.

在本实施例中，在目标会议接入点对应的参会人员的会议终端为一个的情况下，保持目标会议接入点对应的参会人员的会议终端的音频设备处于开启状态。如果一个会议接入点只有一台会议终端，其无法形成“声音循环”，所以也没有必要关闭其扬声器以及声音接收器，一直保持扬声器以及声音接收器正常使用即可。In this embodiment, when there is one conference terminal of a participant corresponding to the target conference access point, the audio device of the conference terminal of the participant corresponding to the target conference access point is kept in an on state. If a conference access point has only one conference terminal, it cannot form a "sound loop", so there is no need to turn off its speakers and sound receivers. Just keep the speakers and sound receivers in normal use.

在本实施例中，根据目标声音信号，确定目标会议接入点对应的参会人员是否处于发言状态。一种可实现的方式为，确定目标声音信号是否为用户讲话声音；在目标声音信号为用户讲话声音的情况下，确定目标会议接入点对应的参会人员处于发言状态；在目标声音信息不是用户讲话声音的情况下，确定目标会议接入点对应的参会人员未处于发言状态。其中，在目标声音信号为用户讲话声音，说明该用户在发言，则该用户处于发言状态；若目标声音信号不为用户讲话声音，目标声音信号也可能为用户动作行为的噪声，在该用户未处于发言状态，可提高对用户发言状态确定的准确率。In this embodiment, it is determined according to the target sound signal whether the participant corresponding to the target conference access point is in a speaking state. One possible way is to determine whether the target sound signal is the user's speaking sound; when the target sound signal is the user's speaking sound, determine that the participant corresponding to the target conference access point is in a speaking state; when the target sound information is not When the user speaks, it is determined that the participant corresponding to the target conference access point is not in the speaking state. Among them, when the target sound signal is the sound of the user speaking, it means that the user is speaking, then the user is in the speaking state; if the target sound signal is not the sound of the user speaking, the target sound signal may also be the noise of the user's action behavior. In the speaking state, it can improve the accuracy of determining the user's speaking state.

在上述实施例中，确定目标声音信号是否为用户讲话声音可以使用神经网络模型，将目标声音信号输入神经网络模型，得到是否为用户讲话声音的结果。In the above embodiment, a neural network model can be used to determine whether the target sound signal is the user's voice. The target sound signal is input into the neural network model to obtain a result of whether it is the user's voice.

发生声音自激时，一个声音从一台会议终端设备扬声器发出，又进入另一台会议终端设备声音接收器，信号又经过网络，回到开始的会议终端设备，使得会议终端设备扬声器又重复发出该声音，如此循环。要想消除声音自激，就必须拆除这种“声音循环”的条件。即，关闭掉部分会议终端的音频设备。为了最大限度减小因为关闭掉部分会议终端设备音频设备而影响会议正常进程，只需要关闭掉多台会议终端处于同一会议接入点且当前未处于发言状态的参会人员的会议终端的音频设备，而当前正处于发言状态的参会人员需要保持音频设备可以正常使用。因此，关闭目标会议接入点中的目标参会人员对应的目标会议终端的音频设备，其中，目标参会人员为目标会议接入点中未处于发言状态的参会人员。When sound self-excitation occurs, a sound is emitted from the speaker of one conference terminal equipment, and then enters the sound receiver of another conference terminal equipment. The signal passes through the network and returns to the original conference terminal equipment, causing the speaker of the conference terminal equipment to repeat the sound. The sound loops like this. In order to eliminate sound self-excitation, this "sound loop" condition must be dismantled. That is, turn off the audio equipment of some conference terminals. In order to minimize the impact on the normal progress of the conference due to turning off the audio equipment of some conference terminal equipment, you only need to turn off the audio equipment of the conference terminals of multiple conference terminals that are at the same conference access point and are not currently speaking. , and participants who are currently speaking need to keep their audio equipment functioning normally. Therefore, the audio device of the target conference terminal corresponding to the target participant in the target conference access point is turned off, where the target participant is a participant in the target conference access point who is not in a speaking state.

由于实际会议场景中，发言的参会人员是可能不断变化的，即，会议终端在“处于发言状态”和“未处于发言状态”之间不断切换。为了进一步减小因为关闭掉部分会议终端的音频设备而影响会议正常进程，关闭时间可以设置为某个时间值。一种可实现的方式为，在关闭目标会议终端的音频设备到达设定时长后，开启述目标会议终端的音频设备。本公开实施例对设定时长不作限定，可以为30秒，60秒等。In actual conference scenarios, the participants who speak may constantly change, that is, the conference terminal constantly switches between "speaking state" and "not speaking state". In order to further reduce the impact on the normal progress of the conference due to turning off the audio equipment of some conference terminals, the shutdown time can be set to a certain time value. One possible way is to turn on the audio equipment of the target conference terminal after turning off the audio equipment of the target conference terminal for a set time period. The embodiment of the disclosure does not limit the set time, and it can be 30 seconds, 60 seconds, etc.

例如，当发生声音自激时，关闭掉多台会议终端处于同一会议接入点且当前未处于发言状态的参会人员的会议终端的音频设备，在到达30秒后，重新开启处于关闭状态的会议终端的音频设备。For example, when sound self-excitation occurs, turn off the audio equipment of the conference terminals of multiple conference terminals that are at the same conference access point and are not currently speaking. After 30 seconds, turn off the audio equipment of the conference terminals that are in the off state again. Audio equipment for conference terminals.
