请参阅图3，本申请实施例提供的语音助手唤醒方法可以应用于如图3所示的应用场景。如图3所示，该应用场景包括多个具备语音助手的电子设备，且唤醒词相同。在本申请实施例中，可将这种应用场景称为多设备场景。在该多设备场景下，用户在说出唤醒词后，采用本申请实施例的方法，即根据多个传感器数据判断电子设备所处的场景，并根据场景优先级选择唤醒最合适应答的电子设备上的语音助手，可以让电子设备更好地感知用户意图，进而让使用者感受到更智能的产品体验。
在一些实施例中，可以通过在电子设备中安装语音助手，以使该电子设备实现语音控制功能。语音助手一般情况下是处于休眠状态的。用户在使用电子设备的语音控制功能之前，需要对语音助手进行语音唤醒。其中，唤醒语音助手的语音数据可以称为唤醒词(或唤醒语音)。该唤醒词可以预先注册在电子设备中。本实施例中所述的唤醒语音助手可以是指，电子设备响应于用户说出的唤醒词，启动语音助手。语音控制功能可以是指：电子设备的语音助手启动后，用户通过说出语音命令(如，一段语音数据)，可以触发电子设备自动执行该语音命令对应的事件。
另外，上述语音助手可以是电子设备中的嵌入式应用(即电子设备的系统应用)，也可以是可下载应用。嵌入式应用是作为电子设备(如手机)实现的一部分提供的应用程序。可下载应用是一个可以提供自己的因特网协议多媒体子系统(Internet Protocol Multimedia Subsystem，IMS)连接的应用程序。可下载应用可以预先安装在电子设备中，也可是由用户下载并安装在电子设备中的第三方应用。
示例性地，如图4所示，所述电子设备可以包括状态感知模块、通信模块、决策模块和唤醒模块。唤醒模块主要用于唤醒语音助手；状态感知模块主要用于计算本电子设备的状态感知数据；决策模块用于负责决策去唤醒哪个电子设备上的语音助手，该模块采用分布式决策方式，每个电子设备的决策模块在收到其它电子设备的状态感知数据后，可根据预设的规则决策出目标唤醒电子设备，并通知唤醒模块；通信模块负责电子设备之间的消息发送和接收。
另，以下实施例中结合图3，以多个设备场景为，该多个电子设备均安装有语音助手，且唤醒词均为“小布小布”为例进行说明。
请参阅图5，图5是本申请实施例提供了一种语音助手唤醒方法的流程示意图，应用于如图3所示的任一电子设备，如图所示，本语音助手唤醒方法包括以下操作。
S510、当接收到用户的语音数据时，获取传感器数据。
在本申请实施例中，对于安装有语音助手的第一电子设备，在该电子设备没有其他软硬件使用麦克风采集语音数据的情况下，第一电子设备的DSP可以通过麦克风实时监测用户是否有语音数据输入。一般情况下，在用户想要使用电子设备的语音控制功能时，可以在电子设备的拾音距离内发声，以将发出的声音输入到麦克风。此时，若第一电子设备没有其他软硬件正在使用麦克风采集语音数据，则第一电子设备的DSP可以通过麦克风监测到对应的语音数据，如语音数据，并进行缓存。
例如，图5a所示，用户坐在客厅的沙发上，在想要使用语音控制功能播放音乐时，可以说出唤醒词“小布小布”。如手机、平板和笔记本均在用户的周围，即用户都在其拾音距离内，且均没有其他软硬件正在使用麦克风采集语音数据，则手机、平板和智能手表的DSP便可通过各自的麦克风检测到唤醒词“小布小布”对应的语音数据。
示例性地，在第一电子设备接收到上述语音数据后，可以对该语音数据进行校验，即判断接收到的该语音数据是否是注册在第一电子设备中的唤醒词。如果校验通过，则表明 接收到的语音数据是唤醒词，可获取传感器数据。如果校验未通过，则表明接收到的语音数据不是唤醒词，此时第一电子设备可以删除缓存的语音数据。
其中，当第一电子设备接收的语音数据是唤醒词时，第一电子设备可拉起决策系统服务，决策系统以服务的形式集成到操作系统中。当操作系统检测到唤醒词，决策系统服务开始注册传感器监听等初始化任务，即操作系统启动传感器监听第一电子设备所处的状态，并通过回调函数的方式将传感器数据传递回来。当所有传感器数据都传递回来后，才通知状态感知模块去读取传感器数据，计算第一电子设备所处的状态。
在本申请实施例中，通过回调函数的方式传递传感器数据是一种异步操作，可以提交系统效率。
S520、根据所述传感器数据确定状态感知数据。
其中，所述传感器数据包括以下至少一项：加速度传感器数据、角速度传感器数据、Z轴加速度数据、距离传感器数据和光线传感器数据，所述状态感知数据包括：第一状态数据、第二状态数据、第三状态数据和设备标识。
示例性地，第一状态数据可以是第一电子设备处于持握状态或平放状态所属数值范围内的数据，第二状态数据可以是第一电子设备处于倒置状态或非倒置状态所属数值范围内的数值，第三状态数据可以是第一电子设备处于裤兜状态、遮挡状态、白天状态、黑夜状态中的任一种所属数值范围内的数值。
可选的，所述根据所述传感器数据确定状态感知数据，包括：根据所述加速度传感器数据和所述角速度传感器数据确定所述第一状态数据；根据所述Z轴加速度数据确定所述第二状态数据；根据所述距离传感器数据和光线传感器数据确定所述第三状态数据。
其中，状态感知模块可以利用加速度传感器和角速度传感器确定电子设备是否处于“持握”或“平放”(非持握)状态对应的数值范围，通过利用加速度传感器，接近传感器和光线传感器确定电子设备是否处于“倒置”，“裤兜”，“遮挡”，“夜晚”和“白天”等五种状态对应的数值范围。
可选的，所述根据所述加速度传感器数据和所述角速度传感器数据确定所述第一状态数据，包括：
根据所述加速度传感器数据的值计算第一夹角，所述第一夹角为所述第一电子设备与水平面的夹角；若所述第一夹角大于或等于预设夹角，将所述第一状态数据的值设置为第一数值，所述第一数值为所述第一状态所属数值范围内的数值；若所述第一夹角小于所述预设夹角，根据所述角速度传感器数据的值判断所述第一电子设备是否抖动；若所述第一电子设备抖动，将所述第一状态数据的值设置为所述第一数值；否则将所述第一状态数据的值设置为第二数值，所述第二数值为非第一状态所属数值范围内的数值。
其中，上述第一状态可以为持握状态，非第一状态可以为平放状态；第二状态可以为倒置状态，非第二状态为非倒置状态；第三状态为裤兜状态。上述第一数值可以是第一状态所属数值范围内的任一数值，第二数值可以是非第一状态所属数值范围内的任一数值。示例性地，还可以构建第一夹角与第一状态所属数值范围内数值的映射关系、第一夹角与非第一状态所属数值范围内数值的映射关系，从而可根据映射关系来确定第一数值或第二数值。可以理解的是，第一状态所属数值范围与非第一状态所属数值范围并不重合。
在实际应用中，可通过判断第一电子设备是否处于持握状态，来确定第一电子设备当前是否被用户使用。通过使用加速度传感器数据来计算第一夹角，可以使得第一电子设备在横屏或竖屏的状态下，只要第一电子设备与水平面的夹角超过预设夹角时，将第一状态数据的值设置为第一数值，可使得决策模块将第一电子设备判定为处于持握状态。
示例性地，如图5b所示，所述持握状态包括但不限于以下几种场景，在如图5b所示的每种场景，第一电子设备都会检测到处于持握状态。
示例性地，上述使用加速度传感器数据计算手机与水平面夹角的公式可表示为：

其中，所述acc_x和acc_y分别为x轴和y轴的重力加速度分量；g为重力加速度，取值为9.81。
示例性地，所述预设夹角可以由系统配置，例如15度；也可以根据用户的使用习惯进行设置。当然本申请对于其他设置预设夹角的方式也不进行限制。
进一步地，在一些场景中，当第一夹角小于预设夹角时，第一电子设备可能仍处于持握状态，例如，用户将第一电子设备放于掌心使用。因此，在第一夹角小于预设夹角时，第一电子设备可以启动抖动检测。通过抖动检测，可以将处于持握状态但第一夹角小于预设夹角的场景下的第一电子设备检测出来。
可选的，所述根据所述角速度传感器数据的值判断所述第一电子设备是否抖动，包括：
根据所述角速度传感器数据的值计算第一角速度，所述第一角速度为所述第一电子设备与所述水平面的角速度；若所述第一角速度小于第一预设角速度且大于第二预设角速度，将所述第一角速度存储于缓存中，否则，清空所述缓存；在所述缓存中的第一角速度的数量大于或等于统计窗口时，计算在采样周期内统计窗口内的第一角速度的平均值；若所述平均值大于或等于第三预设角速度，或者所述第一角速度大于第一预设角速度，确定所述第一电子设备抖动，否则确定所述第一电子设备静止。
示例性地，所述第一角速度为第一电子设备的角速度向量的模，该角速度向量的模计算公式可表示为：
Figure PCTCN2021141207-appb-000002
其中，所述axisX、axisY、axisZ分别为角速度传感器x轴、y轴、z轴的角速度。
示例性地，上述第一预设角速度、第二预设角速度、第三预设角速度、采用周期、统计窗口可以由系统设置，例如，第一预设角速度设置为0.030rad/s、第二预设角速度设置为0.002rad/s、第三预设角速度设置为0.010rad/s、采样周期设置为4、统计窗口设置为20；也可以根据具体实际应用场景进行设置，本申请实施例对此不做限定。
在实际应用中，角速度传感器(例如陀螺仪)上报角速度数据的周期非常短(2.5ms一包)，但是在陀螺仪测量的角速度数据的波动可能会持续一段时间，因此通过拉大统计窗口和间隔采样来过滤掉这种波动。
具体地，状态感知模块接收到陀螺仪上报的角速度瞬时值时，计算上报的角速度向量的模；若角速度向量的模大于第一预设角速度v1或小于第二预设角速度v2时，则状态感知模块清空存储器buffer中存储的角速度向量的模，并在角速度向量的模大于v1时，将第一电子设备判定为抖动；在角速度向量的模小于v2是，将第一电子设备判定为静止。若角速度向量的模大于第一预设角速度v1且小于第二预设角速度v2时，将该角速度向量的模输入buffer中进行缓存，若buffer中存储的角速度向量的模的数量是否小于统计窗口Wstatistics_window，则状态感知模块对下一个接收的角速度瞬时值进行上述计算；若buffer中存储的角速度向量的模的数量是否大于或等于Wstatistics_window，使用采样周期Isamping_interval，间隔采样统计窗口中的角速度，采样的加速度数量为Wstatistics_window/Isamping_interval个，然后计算该Wstatistics_window/Isamping_interval个角速度的平均角速度值Avg，从而减少角速度数据的波动。若平均角速度值Avg小于第三预设角速度，则判断第一电子设备静止；若平均角速度值Avg小于或等于第三预设角速 度，则判断第一电子设备抖动。
可选的，所述根据所述Z轴加速度数据确定所述第二状态数据，包括：若所述Z轴加速度数据的值小于加速度阈值，则将所述第二状态数据的值设置为第三数值，所述第三数值为所述第二状态所属数值范围内的数值，否则将所述第二状态数据的值设置为第四数值，所述第四数值为非第二状态所属数值范围内的数值。
其中，状态感知模块根据加速度传感器上报的z轴上的加速度来设置第二状态数据，从而检测第一电子设备是否处于倒置状态。具体为，若z轴加速度数据的值小于加速度阈值，则将第二状态数据的值设置为第三数值，进而决策模块可将第一电子设备判定为处于倒置状态；若z轴加速度数据的值大于或等于加速度阈值，则将第二状态数据的值设置为第四数值，使得决策模块可将第一电子设备判定为处于非倒置状态。
示例性地，上述加速度阈值可以设置为-9m/s 2，将电子设备倒置时，Z轴的重力加速度与重力加速度的方向相反，Z轴的加速度会小于加速度阈值。
需要说明的是，上述第三数值可以是第二状态所述数值范围内的任一数值。示例性地，所述Z轴加速度数据的值还可以与第二状态所属数值范围内的数值呈映射关系，例如，第二状态所属数值范围为[-1,-2]，当Z轴加速度处于-9.1m/s 2--9.4m/s 2范围内时，可将第二状态数据设置为-1；当Z轴加速度处于-9.5m/s 2--9.8m/s 2范围内时，可将第二状态数据设置为-2。上述第四数值可以是非第二状态所述数值范围内的任一数值。示例性地，所述Z轴加速度数据的值还可以与非第二状态所属数值范围内的数值呈映射关系，例如，非第二状态所属数值范围为[1,4]，当Z轴加速度处于-9.0m/s 2--5.0m/s 2范围内时，可将第二状态数据设置为1；当Z轴加速度处于-4.9m/s 2--1.0m/s 2范围内时，可将第二状态数据设置为2；当Z轴加速度处于-0.9m/s 2-4.0m/s 2范围内时，可将第二状态数据设置为3；当Z轴加速度处于4.1m/s 2-9.8m/s 2范围内时，可将第二状态数据设置为4。当然，本申请实施例也不限制其他将第三数值与第二状态所属数值范围内的数值，以及第四数值与非第二状态所述数值范围内的数值的映射方法。
可选的，所述根据所述距离传感器数据和光线传感器数据确定所述第三状态数据，包括：若所述距离传感器数据的值小于遮挡距离阈值，且所述光线传感器数据的值小于光照强度阈值，则将所述第三状态数据的值设置为第五数值，所述第五数值为所述第三状态所属数值范围内的数值；否则，将所述第三状态数据的值设置为第六数值，所述第六数值为非第三状态所属数值范围内的数值。
其中，所述第三状态为裤兜状态，当第一电子设备处于裤兜状态时，表示用户当前使用第一电子设备的意愿很小，即用户选择唤醒第一电子设备上的语音助手的概率很小。由于裤兜场景中的光线暗同时又有遮挡，可以通过距离传感器和光线传感器来设置第三状态数据的值，进而使得决策模块检测第一电子设备是否处于裤兜状态。具体为当距离传感器上报的数据值小于或等于遮挡距离阈值且光线传感器上报的数据值小于或等于光照强度阈值时，将第三状态数据的值设置为第五数值，决策模块根据第五数值可以判定第一电子设备处于裤兜状态，否则将第三状态数据的值设置为第六数值，决策模块根据第六数值判定第一电子设备处于非裤兜状态。
示例性地，所述遮挡距离阈值可以设置为0、0.1cm、0.2cm等等，所述光照强度阈值可以设置为10勒克斯。
示例性地，所述遮挡距离阈值和光照强度阈值也可以根据用户的习惯进行设置，或者根据具体实际场景进行设置，本申请实施例对此不做限定。
可选的，所述非第三状态包括第四状态、第五状态和第六状态。
示例性地，所述第四状态可以是遮挡状态，所述第五状态可以是夜晚状态，第六状态可以是白天状态。
可选的，所述将所述第三状态数据的值设置为第六数值，包括：若所述距离传感器数据的值小于遮挡距离阈值，且所述光线传感器数据的值大于或等于光照强度阈值，则将所述第三状态数据的值设置为第七数值，所述第七数值为所述第四状态所属数值范围内的数值；若所述距离传感器数据的值大于或等于遮挡距离阈值，且所述光线传感器数据的值小于光照强度阈值，则将所述第三状态数据的值设置为第八数值，所述第八数值为所述第五状态所属数值范围内的数值；若所述距离传感器数据的值大于或等于遮挡距离阈值，且所述光线传感器数据的值大于或等于光照强度阈值，则将所述第三状态数据的值设置为第九数值，所述第九数值为所述第六状态所属数值范围内的数值。
其中，上述非第三状态所属数值范围可以是第四状态所属数值范围、第五状态所属数值范围和第六状态所属数值范围的并集，即第六数值可以是第四状态所属数值范围、第五状态所属数值范围和第六状态所属数值范围中任一数值。
在实际应用中，根据距离传感器可以检测电子设备与目标物体之间的距离，因此通过距离传感器数据的值还可以检测出第一电子设备未放置于裤兜但又有遮挡物的遮挡状态，例如，将手机放于耳侧(如接电听话)的场景。根据光线传感器可以检测出电子设备当前所处环境的光亮程度，因此通过光线传感器数据的值可以检测出第一电子设备是处于黑夜状态还是白天状态。
可选的，所述方法还包括：向所述至少一个第二电子设备发送所述第一电子设备的状态感知数据。
其中，当第一电子设备中的状态感知模块根据传感器数据确定出状态感知数据后，可以将该状态感知数据发送给周围的第二电子设备，以使得该第二电子设备根据周围的多设备的状态感知数据进行决策来选择目标唤醒设备。
示例性地，第一电子设备可在通信模块内设置一个定时器，当第一电子设备接收的语音数据是唤醒词时，开启该定时器，然后在该定时器内广播状态感知模块计算出的状态感知数据。
在本申请实施例中，电子设备将状态感知数据广播以进行多设备状态的同步，可以减少因建立连接带来的时间开销；同时，传感器数据的实时处理，可不需要收集多次传感器数据再做计算，减少了收集传感器数据的时间。这样给用户带来新增功能的同时可以很好地控制语音助手的唤醒时间。
S530、接收来自至少一个第二电子设备的状态感知数据。
在本实施例中，当第一电子设备接收的语音数据是唤醒词时，第一电子设备可使用通信模块监听周围第二电子设备发送的状态感知数据。示例性地，第一电子设备可在通信模块内设置另一个定时器，当第一电子设备接收的语音数据是唤醒词时，开启该定时器，然后在该定时器内接收第一电子设备发送的状态感知模块。示例性地，第一电子设备可在通信模块内设置一个定时器用于，开启广播和接收状态感知数据，定时器超时自动停止广播和接收状态感知数据。
示例性地，上述定时器可由系统设置，例如设置为300ms超时；也可以根据具体实际场景进行设置，本申请实施例对此不做限定。
在本申请实施例中，通过采用广播和接收的方式来同步多设备的状态感知数据，同时采用实时传感器数据处理的方式，可以有效地降低决策时延，提高用户体验。
示例性地，通信模块可封装多种近场通信方式，例如蓝牙(Bluetooth，BT)，低功耗蓝牙(Bluetooth Low Energy，BLE)，WIFI直连(direct)，无线局域网(Wireless Local Area Network，WLAN)等。调用通信模块时可通过参数或者配置文件指定具体选择哪一种通信方式。以BLE为例，BLE广播包会传输包括通用唯一识别码(Universally Unique Identifier，UUID)，MAC地址，蓝牙名字等一系列数据，但是仍然有一部分剩余空间可用于传输自 定义数据，通过计算可知每一条广播包剩余空间最多可以放23个byte，通过将状态感知模块计算出状态感知数据放置于剩余空间中发送给第二电子设备，可以节省BLE GATT建连的时间，进而减少唤醒所需延迟。
在本申请实施例中，若第一电子设备与第二电子设备之间已经建立了连接，则第一电子设备和/或第二电子设备可以复用这条已经建立好的连接，直接进行数据包发送与接收，这样面向已连接的通信方式更可靠，也更安全，同时时延也更低。
需要说明的是，本申请实施例对S520和S530的执行顺序不做限定，即第一电子设备可以同时执行S520和S530；也可先执行S530，在执行S520；还可以先执行S520，在执行S530。
S540、根据所述第一电子设备的状态感知数据和所述至少一个第二电子设备的状态感知数据，确定目标唤醒设备。
在本实施例中，通信模块接收到第二电子设备发送的状态感知数据后，可将第二电子设备的状态感知数据和第一电子设备的状态感知数据一并发送给决策模块，决策模块根据多个设备的状态感知模块确定出目标唤醒设备。
可选的，所述根据所述第一电子设备的状态感知数据和所述至少一个第二电子设备的状态感知数据，确定目标唤醒设备，包括：
根据所述第二状态数据，确定第一候选设备的数量，所述第一候选设备为处于第二状态的所述第一电子设备和/或所述第二电子设备；若所述第一候选设备的数量为1，则将所述第一候选设备确定为所述目标唤醒设备；若所述第一候选设备的数量大于1，则根据所述第三状态数据，从所述第一候选设备中确定第二候选设备的数量，所述第二候选设备为处于第三状态的所述第一候选设备；若所述第二候选设备的数量为1，则将所述第二候选设备确定为所述目标唤醒设备；若所述第二候选设备的数量大于1，则根据所述第一状态数据，从所述第二候选设备中确定第三候选设备的数量，所述第三候选设备为处于第一状态的所述第二候选设备；若所述第三候选设备的数量为1，则将所述第三候选设备确定为所述目标唤醒设备；若所述第二候选设备的数量大于1，则根据所述设备标识从所述第三候选设备中确定所述目标唤醒设备。
具体地，状态感知数据的数据结构可以表示为{isHoldInHand；isUpsideDown；isInPocket；deviceId}。其中isHoldInHand为第一状态数据的值，isUpsideDown为第二状态数据的值，isInPocket为第三状态数据的值，deviceId为设备ID。
在本实施例中，采用链式决策方法，即根据状态感知数据依次进行选择，当选出了唯一的目标唤醒设备时就立即退出，不会往后继续传递，如果传递到最后一条规则，仍没有选择出目标唤醒设备时，则通过设备ID来选择目标唤醒设备。
具体地，首先，决策模块根据状态感知数据中的第二状态数据，从多个设备中选择出处于非第二状态的第一电子设备和/第二电子设备(即处于非倒置状态下的电子设备)，即当电子设备的第二状态数据的值处于第二状态所述数值范围内，则判定该电子设备处于第二状态。若只有一个电子设备处于非第二状态，则将该电子设备确定为目标唤醒设备；若有多个电子设备处于非第二状态下，则从该多个处于非第二状态下电子设备中选择处于非第三状态下的电子设备(处于第四状态、第五状态和第六状态的电子设备)，具体为若电子设备的第三状态数据的值处于非第三状态所述数值范围内，则判定该电子设备处于非第三状态；若没有一个电子设备处于非第二状态(都处于倒置状态)，则从多个设备中选择出非第三状态下的电子设备。若只有一个电子设备处于非第三状态，则直接将该电子设备确定为目标唤醒设备；若有多个电子设备处于非第三状态，则从该多个处于非第三状态下的电子设备中选择处于第一状态下的电子设备，具体为若电子设备的第一状态数据的值处于第一状态所述数值范围内，则判定该电子设备处于第一状态，若没有一个电子设备处于 非第三状态(都处于裤兜状态)，则从多个设备或多个处于非第二状态下电子设备中选择出第一状态下的电子设备。若只有一个电子设备处于第一状态，则直接将该电子设备确定为目标唤醒设备，若有多个或没有一个电子设备处于第一状态，则根据设备ID选择目标唤醒设备。
其中，通过设备ID选择唯一的设备的方式包括但不局限于选择设备ID最小或者设备ID最大或者通过随机算法随机选择一个设备ID。
在本申请实施例中，电子设备根据多个传感器检测的数据来判断电子设备所处的多种场景，并根据场景优先级选择唤醒最合适应答的设备，可以让电子设备更好地感知用户意图，进而让使用者感受到更智能的产品体验。
S550、若所述目标唤醒设备为所述第一电子设备，唤醒语音助手。
其中，决策模块选择出的目标唤醒设备的获取感知数据结构传递给唤醒模块，唤醒模块通过deviceId来判断是否是自己，如果不是则不拉起语音助手，反之则拉起语音助手进行语音应答。
可以看出，本申请实施例提出的语音助手唤醒方法，当第一电子设备接收到用户的语音数据时，获取传感器数据，根据传感器数据确定状态感知数据，然后接收来自至少一个第二电子设备的状态感知数据；根据第一电子设备的状态感知数据和至少一个第二电子设备的状态感知数据，确定目标唤醒设备，在目标唤醒设备为第一电子设备，唤醒语音助手。本申请根据多个电子设备的状态感知数据确定用户需要唤醒的电子设备上的语音助手，可以让电子设备更好地感知用户意图，从而可以从多个电子设备中使得唤醒的用户需求的电子设备上的语音助手，提高用户体验。
