附图说明
图1为一实施例提供的一种电器设备的控制方法的流程图；
图2为一实施例提供的另一种电器设备的控制方法的流程图；
图3为一实施例提供的一种电器设备的控制装置的结构框图；
图4为一实施例提供的一种电器设备的结构示意图。
具体实施方式
下面结合附图和实施例对本公开进行说明。
图1为本实施例提供的一种电器设备的控制方法的流程图，该方法可以由电器设备的控制方法来执行，该装置可以通过软件和/或硬件的方式实现，例如，该装置可以集成在如电视机等电器设备中，也可应用于其他具有语音控制功能的电子产品中。参见图1，本实施例的方法包括如下步骤。
在步骤110中，当接收到待机指令时，判断电器设备的状态。
其中，待机指令可由用户通过遥控器的待机按钮来发送，用户也可向电器设备发送包含有待机指示的语音信息，以控制电器设备将当前模式切换为待机模式。
其中，电器设备的状态可以为网络状态，网络状态可通过读取网络连接标识来进行判断。其中，网络连接标识可通过调用网络检测接口函数来获取，网络连接标识可预先进行设置，例如，如果获取到的网络连接标识为“1”，可表示电器设备处于网络连接状态，如果获取到的网络连接标识为“0”，则表示当前电器设备的网络状态为断开状态。
在步骤120中，根据电器设备的状态选择电器设备的待机模式，所述待机模式包括智能待机模式和默认待机模式，在智能待机模式下，处于关屏状态的电器设备具有接收语音信息及上传语音信息的功能。
其中，智能待机模式是与网络处于连接状态相对应的待机模式，默认待机模式是网络处于断开状态对应的待机模式，即如果电器设备的网络状态为连接状态，则选择智能待机模式作为当前待机模式；或者，如果电器设备的网络状态为断开状态，则选择默认待机模式作为当前待机模式。
其中，默认待机模式为电器设备出厂之前预先设置的待机模式。当电器设备处于默认待机模式时，只有待机指示灯发亮，电器设备的主板不工作，电器设备的多种功能，例如语音识别、显示图像和播放音频等均处于关闭状态。
由于默认待机模式功能较为单一，因此，本实施例中，在默认待机模式的基础上，增加了智能待机模式。当电器设备接收到待机指令时，如果当前电器设备的网络处于连接状态，则进入智能待机模式。此时，可通过调用待机应用接口函数，控制待机指示灯发亮，并关闭显示屏的背光、关闭信号输入、关闭声音通道，但保留语音识别通道正常工作，以保证能够正常接收用户输入的语音信息。
此外，无论是默认待机模式还是智能待机模式，只要检测到开机指令，则点亮电器设备的显示屏并开启多种功能。其中，开机指令可以由用户通过遥控器触发，或者也可以由用户发送包含有开机指示的语音信息。
相对于相关技术中在默认待机模式下电器设备与用户无法进行语音交互的方案，本实施例的技术方案根据电器设备的状态可选择智能待机模式作为当前待机模式，并在智能待机模式下，电器设备可接收并上传用户的语音信息，以实现在待机状态下根据用户的语音信息完成对应的操作，提升了用户体验。
在一实施例中，电器设备的待机模式还可随着时间进行自动切换，例如可以为：当电器设备处于智能待机模式时，检测当前时间段是否处于设定时间段；如果处于设定时间段，则将智能待机模式切换为默认待机模式。这样设置可达 到节省功耗的效果。
其中，设定时间段可以设置为晚上12点第二天凌晨6点，这样设置是考虑到用户在这段时间一般处于休息状态，对电器设备的使用率较低，因此，在这段时间内，可将电器设备的待机模式自动切换为默认待机模式。如果当前时间不在设定时间段内，且电器设备当前处于默认待机模式时，可将当前默认待机模式自动切换为智能待机模式，以等待用户的语音输入或遥控命令的输入。
图2为本实施例提供的另一种电器设备的控制方法的流程图，本实施例在上述实施例的基础上增加了在电器设备处于智能待机模式时进行语音识别的步骤，其中与上述实施例相同或相应的术语的解释在此不再赘述。参见图2，本实施例提供的方法包括以下步骤。
在步骤210中，当接收到待机指令时，判断电器设备的网络状态。
在步骤220中、如果网络状态为连接状态，则选择智能待机模式作为电器设备的待机模式。
在步骤230中，当电器设备处于智能待机模式时，如果获取到语音信息，则对语音信息进行预处理，并将预处理后的语音信息上传到服务器。
其中，对语音信息进行预处理，可以为：对语音信息进行增强处理和降噪处理，并将处理后的语音信息进行脉冲编码调制。
在一实施例中，在对语音信息进行预处理之后，还可经过语音活动检测(Voice Activity Detection，VAD)，得到纯净的语音序列。
示例性的，由于服务器中存储有大量的声学模型和上百条的词库，因此可利用声学模型和词库对语音序列进行语义识别。以电视机为例，当用户发送了“我要看XXX电影”时，通过电视机的麦克风阵列可获取到该语音信息，电视机 内部模数转换器可将该语音信息转换为数字信号，然后可利用处理模块，例如信号数字化处理(Digital Signal Processing，DSP)芯片对转换后的数字信号进行预处理，并将预处理后的数字信号封装成数据包上传到服务器。服务器可以为云端语音识别服务器。该服务器可利用语音拆分、关键词提取和识别等技术，完成对语音信号的解析，并将解析后的语音命令或根据语音命令获取到的电影资源发送到电视机。
示例性的，若语音序列为简单语音序列构成，则可以在电视机本地直接进行语音识别，以获取识别得到的语音命令或是语音命令对应的资源。
本实施例将采集到的语音信息上传到云端进行语义识别，从而减少本地语音识别的计算量，提升离线语音指令识别的准确性。
在步骤240中，接收服务器对语音信息的识别结果，并根据识别结果控制电器设备进行相应的操作。
本实施例中，根据识别结果控制电器设备进行相应的操作是开启了智能待机模式下电器设备的一些功能，例如显示功能、音频和视频的播放等功能。其中，上述功能的开启需配合电器设备的硬件来实现，例如可通过调用本地硬件接口函数，将某个待开启功能所对应的硬件模块的开关引脚的电平设置为高电平，以使硬件模块能够正常工作，以开启该硬件所能实现的功能。
示例性的，根据识别结果控制当前电器设备进行相应的操作，可以包括以下步骤。
如果识别结果为播放音频信号，则保持当前电器设备的关屏状态并控制当前电器设备的音频播放功能开启，播放所述音频。
本实施例进行语音识别是在电器设备处于智能待机模式状态进行的。在智能待机模式状态时，电器设备的语音功能开启，而显示功能以及音频播放等其 他功能仍处于关闭状态。如果语音信息的识别结果为播放音频信号，此时，只需开启音频播放功能即可，为了节省功耗，无需开启其他功能，例如无需点亮电器设备的显示屏，即保持电器设备的关屏状态并进行音频信号的播放。
在一实施例中，如果电器设备为电视机，则当电视机处于智能待机模式时，如果用户发送的播放音频的语音指令，则电视机可作为音箱来进行音频的播放。
示例性的，如果服务器发送的识别结果为播放视频信号，则点亮电器设备的显示屏，以开启显示功能，并播放视频。
本实施例在上述实施例的基础上，在智能待机状态下，根据用户的语音指令开启电器设备的对应功能，并控制电器设备执行对应的操作，而无需先将电器设备切换为开机状态再根据识别结果进行对应的操作，达到了节省功耗的效果。
在一实施例中，用户还可通过向处于智能待机状态的电器设备发送语音指令，以控制家庭中的其他智能家居设备，例如可控制智能音箱、台灯或空调等进行模式切换、音量调节等。
