Description

一种触发电子设备执行功能的方法及电子设备 技术领域
本实施例涉及电子设备领域，尤其涉及一种触发电子设备执行功能的方法及电子设备。
背景技术
通常，用户可以通过对手机的物理按键(如音量“+”键，电源键等)进行触发操作，或在手机显示屏上进行触摸操作以触发手机执行对应的功能。而在用户不方便使用手指操作手机时，往往选择通过语音控制手机执行对应功能。目前，语音助手可以为用户提供语音控制服务，以实现通过语音控制手机执行对应功能的目的。语音助手是人工智能在手机上的重要应用。语音助手可以识别用户输入的语音命令，并触发手机执行该语音命令对应的功能，从而实现用户与手机的智能交互。
但是，通常情况下，语音助手是处于休眠状态的，用户在使用语音助手前，需要对语音助手进行语音唤醒。只有在语音助手被唤醒后，才可以接收并识别用户输入的语音命令。用于唤醒语音助手的语音数据可以称为唤醒词(或称为唤醒语音)。唤醒词可以是用户预先注册在手机中的。例如，预先注册在手机中的唤醒词为“你好小E”。如果用户想要使用语音助手触发手机将手机的音量调小，则先需说出“你好小E”，来唤醒语音助手。在语音助手被唤醒后，用户再说出“调小手机音量”。此时，语音助手才可以接收并识别用户的语音命令“调小手机音量”，并触发手机将音量调小。
可以看到的是，用户需要多次输入语音数据才能够触发手机执行对应的功能，极大降低了手机的使用效率。
发明内容
本实施例提供一种触发电子设备执行功能的方法及电子设备，无需用户多次输入语音数据便可触发电子设备执行对应功能，提高了电子设备的使用效率，实现了电子设备与用户之间的高效互动。
为达到上述目的，本实施例提供如下技术方案：

本实施例提供的技术方案，电子设备可以在接收到的语音数据通过校验后，将电子设备的主处理器从休眠状态唤醒，并确定输入的语音数据对应的指令，以触发电子 设备通过主处理器执行该指令对应的功能。可以看到的是，只要电子设备没有其他软硬件使用麦克风采集语音数据(即使处于黑屏状态，且AP处于休眠状态)，不需要用户先输入唤醒词，以使电子设备启动语音助手，再输入语音命令，而是输入一条语音数据便可唤醒电子设备的主处理器，并触发电子设备执行对应的功能。这样，提高了电子设备的使用效率，实现了电子设备与用户之间的高效互动。同时，提高了用户的使用体验。
结合第一方面，在一种可能的实现方式中，在电子设备将主处理器从休眠状态唤醒之前，该方法还可以包括：电子设备确定第一语音数据的声纹特征与至少两个第一唤醒词对应的声纹特征匹配。这样，只有在电子设备中注册过唤醒词的人才能够通过输入语音数据触发电子设备执行对应功能，提高了语音控制服务的使用安全性。

示例性的，以下实施例中所涉及的技术方案均可以在具有上述硬件架构和软件架构的电子设备100中实现。以下结合附图和应用场景对本实施例提供的触发电子设备执行功能的方法进行详细介绍。
图3为本实施例提供的一种触发电子设备执行功能的方法的流程示意图。如图3所示，该方法可以包括以下S301-S304。
其中，电子设备中设置有一个或多个第一唤醒词。该第一唤醒词可以是预定义的，也可以是用户自定义的。如果第一唤醒词是用户自定义的，那么在电子设备中注册第一唤醒词的过程可以参考常规技术中的具体描述，本实施例此处不予赘述。该第一唤醒词可以是用户会经常用到的语音命令，如“静音”，“接听电话”等。电子设备中设置的第一唤醒词可以对应一个第一指令。在本实施例中，当电子设备中设置有多个第一唤醒词(或者，称为至少两个第一唤醒词)时，电子设备响应不同第一唤醒词对应的第一指令所执行的功能是不同的。以下实施例中，以电子设备中设置有至少两个第一唤醒词为例进行详细说明。
S301、电子设备接收用户输入的第一语音数据。
其中，在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，电子设备的第一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，在用户想要通过输入语音数据触发电子设备执行某些功能时，可以靠近手机的麦克风发声，以将发出的声音输入到麦克风。此时若电子设备没有其他软硬件正在使用麦克风采集语音数据，则电子设备的第一DSP可以通过麦克风监测到对应的语音数据，如第一语音数据。
需要说明的是，在本实施例中，电子设备处于黑屏，锁屏，亮屏等任何状态时，只要电子设备没有其他软硬件正在使用麦克风采集语音数据，电子设备的第一DSP均可以监测用户的语音数据。其中，在黑屏状态下，电子设备的AP可以处于休眠状态，也可以处于非休眠状态。
S302、电子设备判断至少两个第一唤醒词中是否存在文本与第一语音数据对应的文本匹配的唤醒词。
其中，在电子设备接收到上述第一语音数据后，可以对该第一语音数据进行文本校验，即判断设置在电子设备中的至少两个第一唤醒词中，是否存在文本与第一语音数据对应的文本匹配的唤醒词，以确定接收到的第一语音数据是否是设置在电子设备中的第一唤醒词。
如果文本校验通过，则表明接收到的第一语音数据是设置在电子设备中的第一唤醒词，此时电子设备可以执行S303。如果文本校验未通过，则表明接收到的第一语音数据不是设置在电子设备中的第一唤醒词，此时电子设备可以执行S304。
在一些实施例中，电子设备对第一语音数据进行文本校验具体的可以包括：电子 设备的第一DSP对该第一语音数据进行文本校验，和/或，电子设备的AP对该第一语音数据进行文本校验。其中，如果电子设备对第一语音数据进行文本校验具体包括：第一DSP对该第一语音数据进行文本校验，以及AP对该第一语音数据进行文本校验，那么，第一DSP与AP进行文本校验时的精度可以不同。例如，第一DSP对第一语音数据进行第一精度的文本校验，AP对第一语音数据进行第二精度的文本校验，第一精度小于第二精度。
例如，以电子设备对第一语音数据进行文本校验具体包括：第一DSP对该第一语音数据进行第一精度的文本校验，以及AP对该第一语音数据进行第二精度的文本校验，电子设备的AP处于休眠状态为例详细介绍对第一语音数据进行文本校验的过程。在电子设备的第一DSP监测到第一语音数据后，第一DSP可以对该第一语音数据进行第一精度(或称为低精度)的文本校验。也就是说，第一DSP可以判断至少两个第一唤醒词中，是否存在文本与第一语音数据对应的文本的匹配度满足第一精度的唤醒词。若第一DSP确定至少两个第一唤醒词中，存在文本与第一语音数据对应的文本的匹配度满足第一精度的唤醒词，也就是说，第一DSP对第一语音数据的第一精度的文本校验通过，则第一DSP可以唤醒电子设备的AP，并将监测到的第一语音数据传输至AP。如果第一DSP确定至少两个第一唤醒词中，不存在文本与第一语音数据对应的文本的匹配度满足第一精度的唤醒词，则表明接收到的第一语音数据不是设置在电子设备中的第一唤醒词，电子设备可以执行S304。
电子设备的AP接收到第一语音数据后，可以对该第一语音数据进行第二精度(或称为高精度)的文本校验。也就是说，AP可以判断至少两个第一唤醒词中，是否存在文本与第一语音数据对应的文本的匹配度满足第二精度的唤醒词。如果AP确定至少两个第一唤醒词中存在文本与第一语音数据对应的文本的匹配度满足第二精度的唤醒词，即AP对第一语音数据的第二精度的文本校验通过，则表明接收到的第一语音数据是设置在电子设备中的第一唤醒词，电子设备可以执行S303。如果电子设备的AP确定至少两个第一唤醒词中不存在文本与第一语音数据对应的文本的匹配度满足第二精度的唤醒词，即AP对第一语音数据的第二精度的文本校验未通过，则表明接收到的第一语音数据不是设置在电子设备中的第一唤醒词，电子设备可以执行S304。
S303、电子设备确定第一语音数据对应的第一指令，通过电子设备的主处理器执行第一指令对应的功能。
如果电子设备确定出至少两个第一唤醒词中存在文本与第一语音数据对应的文本匹配的唤醒词，则电子设备可以确定第一语音数据对应的第一指令，并执行第一指令对应的功能，以实现通过输入语音数据触发电子设备执行对应功能的目的。
例如，电子设备确定第一语音数据对应的第一指令，具体可以为：电子设备中存储有设置在电子设备中的至少两个第一唤醒词与指令的对应关系。在电子设备对第一语音数据的文本校验通过后，电子设备可以查找该对应关系，以确定出第一语音数据对应的第一指令。
又例如，电子设备可以对该第一语音数据的文本进行语义分析，以确定该第一语音数据对应的第一指令。电子设备的语义分析功能可以以某个单独的模块在电子设备中实现，也可以由集成在某个应用程序中模块实现。如，语音分析功能由集成在语音 助手中的模块实现。那么，在电子设备确定出至少两个第一唤醒词中存在文本与第一语音数据对应的文本匹配的唤醒词时，电子设备可以启动语音助手，通过语音助手对第一语音数据对应的文本进行语义分析，以确定该第一语音数据对应的第一指令，并通过主处理器触发电子设备执行该第一指令对应的功能。可以看到的是，在该实现方式中，第一语音数据不仅可以作为唤醒词唤醒语音助手，还可以作为语音命令触发电子设备执行对应功能。上述语音助手可以是安装在电子设备中的应用程序(Application，APP)。在本实施例中，语音助手可以是系统应用，也可以是第三方应用。系统应用，也可称为嵌入式应用，其是作为电子设备实现的一部分提供的应用程序。第三方应用，也可称为可下载应用，其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，可以预先安装在电子设备中，也可以由用户下载并安装在电子设备中。
S304、电子设备删除第一语音数据。
本实施提供的触发电子设备执行功能的方法，电子设备可以在接收到的语音数据通过校验后，确定输入的语音数据对应的指令，以触发电子设备执行该指令对应的功能。可以看到的是，只要电子设备没有其他软硬件使用麦克风采集语音数据(即使处于黑屏状态，且AP处于休眠状态)，不需要用户先输入唤醒词，以使电子设备启动语音助手，再输入语音命令，而是输入一条语音数据便可触发电子设备执行对应的功能。这样，提高了电子设备的使用效率，实现了电子设备与用户之间的高效互动。同时，提高了用户的使用体验。
在一些实施例中，如果上述第一唤醒词是用户自定义的唤醒词，那么，在对第一语音数据进行文本校验通过后，可以继续对其进行声纹校验。也就是说，在文本校验通过后，AP可以判断第一语音数据的声纹特征与设置在电子设备中的至少两个第一唤醒词对应的声纹特征是否匹配。如果第一语音数据的声纹特征与设置在电子设备中的至少两个第一唤醒词对应的声纹特征匹配，则对第一语音数据的声纹校验通过，电子设备可以执行上述S303。如果第一语音数据的声纹特征与设置在电子设备中的至少两个第一唤醒词对应的声纹特征不匹配，则对第一语音数据的声纹校验未通过，电子设备可以执行上述S304。也就是说，在电子设备接收到上述第一语音数据后，可以在对该第一语音数据进行文本校验和声纹校验均通过后，才可执行上述S303。这样，只有在电子设备中注册过唤醒词的人才能够通过输入语音数据触发电子设备执行对应功能，提高了语音控制服务的使用安全性。
例如，在电子设备中设置该至少两个第一唤醒词时，电子设备可以根据设置至少两个第一唤醒词时用户输入的语音数据生成第一声纹模型。该第一声纹模型可以用于表征该至少两个第一唤醒词的声纹特征。若电子设备确定出至少两个第一唤醒词中存在文本与第一语音数据对应的文本匹配的唤醒词，即文本校验通过，则AP可以继续根据该第一声纹模型对上述第一语音数据进行声纹校验。具体的：电子设备生成第一声纹模型后，可以将设置至少两个第一唤醒词时用户输入的语音数据作为输入值，输入到第一声纹模型后得到第一声纹门限。在电子设备确定监测到的第一语音数据通过文本校验后，可以将该第一语音数据作为输入值，输入到第一声纹模型后得到一个声纹值，如第二声纹值。电子设备可以判断该第二声纹值与第一声纹门限的差值是否小 于预设阈值。如果该第二声纹值与第一声纹门限的差值小于预设阈值，则声纹验证通过。如果该第二声纹值与第一声纹门限的差值大于或者等于预设阈值，则声纹验证未通过。
示例性的，以电子设备中设置有多个预定义的第一唤醒词为例。例如，如表1所示，电子设备中设置的第一唤醒词包括如下常用的语音命令：系统设置命令，如“静音”，“取消静音”，“调高音量”(或“声音大一点”)，“调低音量”(或“声音小一点”)，“锁定屏幕”等。导航设置命令，如“退出导航”，“停止导航”，“切换路线”(或“换一条路线”)，“导航回家”，“导航去公司”等。音乐设置命令，如“上一首”，“下一首”(或“切歌”)，“暂停音乐”(或“暂停播放”)，“开始音乐”(或“开始播放”)，“停止音乐”(或“停止播放”)等。通信设置命令，如“挂断电话”，“接听电话”，“查看短信”，“回复短信”，“朗读短”信，“读微信”，“回复微信”等。
表1
Figure PCTCN2018109888-appb-000001
例如，电子设备通过语音助手进行语义分析获得语音数据对应的指令。电子设备当前没有其他软硬件使用麦克风采集语音数据。且如图4中的(a)所示，电子设备处于黑屏状态，电子设备的AP也处于休眠状态。用户想要通过输入语音数据触发电子设备将电子设备的音量调小。用户可以靠近手机的麦克风说出“调低音量”。电子设备的第一DSP可以通过麦克风监测到对应的语音数据“调低音量”。第一DSP监测到语音数据“调低音量”后，可以对该语音数据“调低音量”进行第一精度的文本校验。在第一DSP对语音数据“调低音量”的第一精度的文本校验通过时，第一DSP可以唤醒AP，并将语音数据“调低音量”传输至AP。AP可以对该语音数据“调低音量”进行第二精度的文本校验。在AP对语音数据“调低音量”的第二精度的文本校验通过时，可以启动语音助手，并通过语音助手对语音数据“调低音量”进行语义分析，以确定出该语音数据“调低音量”对应的指令。此时AP根据该指令触发电子设备将系统的音量调低。
为了方便用户获知输入语音数据后，电子设备是否已经进行了相应的响应。电子设备可以在进行了相应的响应后，点亮屏幕并显示提示信息，以提示用户已进行了相应的响应。例如，结合上述示例，如图4中的(b)所示，在语音助手启动后，电子设备可以点亮屏幕，并显示语音助手界面401。该语音助手界面401中可以包括识别出的用户输入的语音数据对应的文字“调低音量”402。在电子设备将系统的音量调低后，在语音助手界面401中可以显示提示信息403。该提示信息403用于向用户提示已将系统的音量调低。可以看到的是，在电子设备处于黑屏状态，且AP处于休眠状态的情况下，无需用户先输入语音数据“你好小E”，来唤醒语音助手，再输入语音数据“调 小手机音量(或调低音量)”，而是只需输入一条语音数据“调低音量”，便可触发电子设备将音量调低，达成意图。提高了人机交互的效率，用户体验有了很大的提升。
可以理解的是，由于上述第一DSP具有较高的处理能力，因此其功耗也相对较高。在本实施例中，为了在实现电子设备与用户之间高效互动的同时，尽可能的节省电子设备的功耗。可以仅在特定的场景下使用上述第一DSP对麦克风采集到的语音数据进行处理。也就是说，可以仅在特定的场景下通过执行以上S301-S304，以达到通过输入语音数据触发电子设备执行对应功能的目的。即如图5所示，在上述S301之前，该触发电子设备执行功能的方法还可以包括S501。
S501、电子设备进入预定模式。
其中，该预定模式可以是驾驶模式，居家模式等。在该预定模式下，当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，电子设备的麦克风可以将采集到的语音数据传输至电子设备的第一DSP，以便第一DSP对语音数据进行处理。
在一些实施例中，电子设备可以在某些特定情况下自动进入预定模式。示例性的，电子设备可以在某些特定的时间段，或某些特定的地点自动进入预定模式。
一般的，电子设备可以利用历史使用记录获取用户在当前地点或当前时间使用电子设备的意图，如是否通过输入语音数据触发电子设备执行对应功能。在使用电子设备的意图是通过输入语音数据触发电子设备执行对应功能时，电子设备可以自动进入预定模式。也就是说，电子设备可以利用历史使用记录确定用户频繁通过输入语音数据触发电子设备执行对应功能的时间和/或地点。在确定当前时间或当前地点与历史使用记录相匹配时，电子设备可以自动进入预定模式。例如，电子设备获取到用户在19:00-20:30这个时间段内经常通过输入语音数据触发电子设备执行对应功能。那么，电子设备可以在确定当前系统时间处于19:00-20:30这个时间段时，自动进入预定模式。又例如，电子设备获取到用户在某个地理位置范围内(如该地理位置范围是用户的家)经常通过输入语音数据触发电子设备执行对应功能，那么，电子设备可以在确定当前电子设备所述的地理位置处于该地理位置范围内时，自动进入预定模式(如居家模式)。
在其他一些实施例中，电子设备可以在确定电子设备的移动速度大于特定值时自动进入预定模式(如驾驶模式)。一般的，当用户在驾驶汽车时，可能会较频繁的通过输入语音数据触发电子设备执行对应功能，如通过语音助手触发电子设备的地图应用进行导航等。因此，当电子设备检测到电子设备当前的移动速度大于特定值时，自动进入预定模式(如驾驶模式)。
在另外一些实施例中，电子设备可以响应于用户的特定输入，进入预定模式。该特定输入可以是用户对某特定虚拟按钮或物理按键的触发操作。例如，以特定输入是用户对特定虚拟按钮(如“预定模式”选项的开关按钮)的触发操作为例。电子设备包括设置(Settings)。如图6所示，电子设备可以接收用户对设置的图标的点击操作。响应于用户对设置的图标的点击操作，电子设备可以显示图6所示的设置界面601。该设置界面601中可以包括“飞行模式”设置选项、“WLAN”设置选项、“蓝牙”设置选项、“移动网络”设置选项、“预定模式”设置选项(如图6中以“驾驶模式”设置选项为例示出)等。其中，“飞行模式”选项、“WLAN”选项、“蓝牙”选项 和“移动网络”选项的具体功能可以参考常规技术中的具体描述，本实施例这里不予赘述。用户在想要使用上述第一唤醒词触发电子设备执行对应功能时，可以对“驾驶模式”选项的开关按钮602进行点击操作。电子设备响应于用户对“驾驶模式”选项的开关按钮602的点击操作，可以进入预定模式，如驾驶模式。当用户再次对“驾驶模式”选项的开关按钮602执行点击操作后，电子设备可以退出驾驶模式。其中，图6所示的“驾驶模式”选项的开关按钮602的显示效果，用于指示驾驶模式未打开，用户此时可以对该开关按钮602执行点击操作，以便该电子设备进入驾驶模式。
上述特定输入也可以是用户输入的语音命令。该语音命令可以是通过电子设备的语音助手输入的。例如，电子设备中还可以设置有第二唤醒词。该第二唤醒词可以用于唤醒电子设备中的语音助手。在用户通过第二唤醒词唤醒语音助手后，便可以通过语音助手输入语音命令，以触发电子设备进入上述预定模式。在电子设备进入预定模式之前，电子设备可以使用另一DSP，如第二DSP监测语音数据，以便可以通过第二唤醒词唤醒语音助手。在电子设备退出上述预定模式后，或者未处于上述预定模式下时，电子设备可以使用该第二DSP对麦克风采集到的语音数据进行处理。由于第二DSP的处理性能相较于第一DSP的处理性能低，内存相较于第一DSP的内存小。因此，其功耗相较于第一DSP的功耗低。这样，不仅可以保证在预定场景下用户使用语音助手时电子设备与用户之间的高效互动，同时节省了电子设备的功耗。而且，在电子设备处于非特定的场景下时，仍可以通过语音助手触发电子设备执行对应功能，如触发电子设备进入预定模式。
示例性的，以语音助手处于休眠状态为例。在用户想要通过语音助手输入语音命令触发电子设备进入预定模式时，用户可以靠近手机的麦克风发声，以将发出的声音输入到麦克风。此时电子设备的第二DSP可以通过麦克风监测到用户输入的语音数据，如第二语音数据。在电子设备的第二DSP监测到第二语音数据后，电子设备可以判断该第二语音数据与设置在电子设备中的第二唤醒词是否匹配。当第二语音数据与第二唤醒词匹配时，可以启动语音助手。此时用户可以通过语音助手输入用于触发电子设备进入预定模式的语音数据，如第三语音数据。电子设备通过语音助手可以接收到用户输入的第三语音数据，并确定该第三语音数据对应的第二指令。该第二指令可以用于指示电子设备进入预定模式。电子设备可以执行第二指令对应的功能，即进入预定模式。
其中，电子设备判断第二语音数据与设置在电子设备中的第二唤醒词是否匹配具体的可以是：电子设备对第二语音数据进行文本校验，如果第二语音数据对应的文本与第二唤醒词的文本匹配，则文本校验通过，第二语音数据与第二唤醒词匹配。如果第二语音数据对应的文本与第二唤醒词的文本不匹配，则文本校验未通过，第二语音数据与第二唤醒词不匹配。或者，电子设备判断第二语音数据与设置在电子设备中的第二唤醒词是否匹配具体的可以是：电子设备对第二语音数据进行文本校验和声纹校验。如果第二语音数据对应的文本与第二唤醒词的文本匹配，且第二语音数据的声纹特征与第二唤醒词对应的声纹特征匹配，则文本校验和声纹校验通过，第二语音数据与第二唤醒词匹配。如果第二语音数据对应的文本与第二唤醒词的文本不匹配，或第二语音数据的声纹特征与第二唤醒词对应的声纹特征不匹配，则文本校验和声纹校验 未通过，第二语音数据与第二唤醒词不匹配。
在一些实施例中，电子设备对第二语音数据进行文本校验可以包括：电子设备的第二DSP对第二语音数据进行第三精度的文本校验，和/或，电子设备的AP对第二语音数据进行第四精度的文本校验。第三精度小于第四精度。其中，第三精度可以与上述第一精度相同，也可以与第一精度不同。第四精度可以与上述第二精度相同，也可以与上述第一精度不同。
例如，以电子设备判断第二语音数据与设置在电子设备中的第二唤醒词是否匹配具体包括：电子设备对第二语音数据进行文本校验和声纹校验。电子设备对第二语音数据进行文本校验包括：第二DSP对第二语音数据进行第三精度的文本校验，以及AP对第二语音数据进行第四精度的文本校验为例，详细说明电子设备判断第二语音数据与第二唤醒词是否匹配的过程。电子设备的第二DSP监测到第二语音数据后，可以判断第二语音数据对应的文本与第二唤醒词的文本的匹配度是否满足第三精度。如果第二语音数据对应的文本与第二唤醒词的文本的匹配度满足第三精度，则可以将第二语音数据传输至AP。AP可以判断第二语音数据对应的文本与第二唤醒词的文本的匹配度是否满足第四精度。如果第二语音数据对应的文本与第二唤醒词的文本的匹配度满足第四精度，电子设备的AP可以判断第二语音数据的声纹特征与第二唤醒词对应的声纹特征是否匹配。如果第二语音数据的声纹特征与第二唤醒词对应的声纹特征匹配，则表明第二语音数据是设置在电子设备中的第二唤醒词，此时电子设备可以启动语音助手。
在电子设备进入预定模式后，用户若想通过输入语音数据触发电子设备执行对应功能，则仅需输入上述第一唤醒词，便可实现意图。也就是说，在电子设备进入预定模式后，用户无需多次输入语音数据，而是直接上述第一唤醒词，便可以触发电子设备执行对应功能。在实现电子设备与用户之间高效互动的同时，尽可能的节省电子设备的功耗。
以下结合图7、图8和具体实例，对本实施例提供的触发电子设备执行功能的方法进行具体介绍。例如，电子设备为手机。手机中包括语音助手。手机通过语音助手对用户输入的语音数据对应的文本进行语义分析以获得对应指令。该手机包括两个DSP，分别为DSP 1和DSP 2。手机包括的麦克风同一时间仅与这两个DSP中的其中一个DSP建立通路。麦克风默认与DSP2建立了通路。在手机进入驾驶模式后，将麦克风通路由DSP 2切换到DSP 1。
手机中设置有5个预定义的第一唤醒词，分别为：“退出导航”，“停止导航”，“切换路线”，“导航回家”，“导航去公司”。手机中还设置有1个第二唤醒词，“你好小E”。
如图7中的(a)所示，手机处于黑屏状态。AP处于休眠状态。语音助手处于休眠状态。用户在驾驶汽车时，靠近手机的麦克风说出“你好小E”。手机的麦克风采集到“你好小E”对应的语音数据1。手机的麦克风将采集到的语音数据1传输至DSP 2。DSP 2判别该语音数据1对应的文本与设置到手机中的第二唤醒词“你好小E”的文本的匹配度是否满足精度1，以确定语音数据1是否疑似是设置在手机中的第二唤醒词“你好小E”。DSP 2在确定接收到的语音数据1疑似是设置在手机中的第二唤醒 词“你好小E”时，将AP从休眠状态唤醒，并将语音数据1传输手机的AP。AP接收到语音数据1后，判断该语音数据1对应的文本与设置到手机中的第二唤醒词“你好小E”的文本的匹配度是否满足精度2。精度2大于精度1。手机的AP在确定该语音数据1对应的文本与设置到手机中的第二唤醒词“你好小E”的文本的匹配度满足精度2时，判断该语音数据1的声纹特征与第二唤醒词“你好小E”对应的声纹特征是否匹配，即进行声纹校验。如果声纹校验通过。手机的AP可以唤醒语音助手。如图7中的(b)所示，手机点亮屏幕，并显示语音助手界面701。该语音助手界面701中可以包括提示信息702。该提示信息702用于提示用户此时可输入语音命令，以触发手机执行对应功能。
用户靠近手机的麦克风说出“进入驾驶模式”。手机可以通过语音助手接收到对应的语音数据2。如图7中的(c)所示，手机可以在语音助手界面703中显示语音数据2对应的文字“进入驾驶模式”704。手机通过语音助手对该语音数据2进行语义分析，以确定出该语音数据2对应的指令。手机可以根据该指令触发手机进入驾驶模式。并且，手机将麦克风通路由DSP 2切换到DSP 1。在手机进入驾驶模式后，如图7中的(c)所示，手机可以在语音助手界面703中显示提示信息705。该提示信息705用于提示用户已进入驾驶模式，后续可直接说出第一唤醒词以触发手机执行对应功能。
一般的，手机根据语音助手接收到的语音数据执行了对应功能后，语音助手会进入空闲态。或者手机会在确定预定时间内没有接收到用户操作时，控制语音助手重新进入休眠状态。另外，在一定时间内若没有接收到用户操作，AP也可能会重新进入休眠状态。在现有技术中，语音助手在空闲态或者进入休眠状态(或者语音助手在空闲态或者进入休眠状态，且AP也处于休眠状态)后，如果用户想要再次使用语音助手触发手机执行对应功能，则需要重新输入唤醒词，然后再输入语音命令，才能达成意图。但是，在本实施例中，在手机进入驾驶模式后，即使语音助手在空闲态或者进入休眠状态(或者语音助手在空闲态或者进入休眠状态，且AP处于休眠状态)，用户只需输入上述第一唤醒词便可达成意图。
例如，以手机进入驾驶模式后，语音助手重新进入休眠状态，且如图8中的(a)所示，手机重新处于黑屏状态，AP处于休眠状态。用户靠近手机的麦克风说出“导航回家”。手机的麦克风采集到“导航回家”对应的语音数据3。手机的麦克风将采集到的语音数据3传输至DSP 1。DSP 1可以对语音数据3进行较低精度的文本匹配，即判别设置在手机中的5个第一唤醒词中，是否存在文本与该语音数据3对应的文本的匹配度满足精度3的唤醒词。DSP 1在较低精度的文本匹配通过时，唤醒AP，并将语音数据3传输至AP。此时手机的AP可以对语音数据3进行较高精度的文本匹配，即判别设置在手机中的5个第一唤醒词中，是否存在文本与该语音数据3对应的文本的匹配度满足精度4的唤醒词。精度4大于精度3。在较高精度的文本校验通过时，手机可以唤醒语音助手。手机还可以通过语音助手对语音数据3进行语义分析，以确定出该语音数据3对应的指令。手机可以根据该指令调用对应的接口，以触发地图应用展示对应的导航路线给用户(或者手机也可以根据该指令模拟用户的点击操作，以便在地图应用中展示对应的导航路线给用户)。手机还可以通过扬声器播报导航路线信息。例如，如图8中的(b)所示，手机可以点亮屏幕，并显示语音助手界面801。该 语音助手界面801中可以包括识别出的用户输入的语音数据3对应的文字“导航回家”802。其中，该语音助手界面801是一个跳转界面，即手机的显示屏上显示语音助手界面801后立即跳转到图8中的(c)所示的导航界面803。在一些实施例中，手机的显示屏上也可以不显示语音助手界面801，而是在用户输入“导航回家”后，手机直接点亮屏幕，显示导航界面803。这样，用户无需多次输入语音数据，便可达成意图。提高了人机交互效率，提高了用户体验。
