根据文本信息查找对应的控制指令，成功找到与文本信息对应的控制指令后，则获取与文本信息对应的控制指令，控制指令中包括被控制电器的识别信息和动作指令；若未成功查找到与文本信息对应的控制指令，则继续检测外界环境语音获取用户语音指令，避免因为获取错误的控制指令而使被控制电器执行了错误的动作指令，给用户带来困扰。
步骤S30、根据所述控制指令，在预置数据库中查找并获取与控制指令匹配的无线控制码和被控制电器的控制类型。
根据获取的控制指令中的被控制电器识别信息，在预置的数据库中查找被控制电器对应的控制类型，获取被控制电器的控制类型；若未获取被控制电器的控制类型，则继续检测外界环境语音获取用户语音指令。需要说明的是，预置数据库中被控制电器的控制类型可以是红外线、蓝牙、WiFi(WIreless-Fidelity，无线网)和ZigBee(无线个域网)，也可以是其他类型，可以根据实际需要灵活设置。

需要说明的是，作为一种具体的应用实例，融合上述实施例中各功能模块，实现智能家居的语音控制装置可以包括以下四个子系统：
1：SensorHub低功耗待机检测子系统；SensorHub低功耗待机检测子系统负责完成移动终端在待机状态下的外界环境声音检测。
2：语音识别子系统；语音识别子系统包括语音识别操作引擎、语义分析识别操作引擎和语音播报模块。语音识别操作引擎用以负责用户语音转文字，识别用户的原始语音指令，将原始的语音指令转为文字或字符指令。同时，语音识别操作引擎与移动终端安全解锁系统连接，给移动终端提供了另外一种语音解锁方案。语义分析识别操作引擎，用以负责对语音识别引擎转换成功的文字或字符指令进行语义分析，分析后的结果为通用接口可识别的控制命令；语音播报模块负责对EGP模块发送的搜索结果信息进行语音播报。
3：ECHONET家庭网络连接子系统；ECHONET家庭网络连接子系统包括：红外发送及接收模块、wifi模块、蓝牙模块以及具有转发和路由能力的FFD(Full Function Device)ZigBee节点。红外发送及接收模块完成对红外信号的发送，以此来可以控制各类的红外电视机或机顶盒设备；wifi模块完成无线wifi数据信号的发送，以此来控制各类智能wifi电视或机顶盒或视频盒子设备；蓝牙模块完成对蓝牙信号的发送，以此来控制各类智能蓝牙电视或机顶盒或视频盒子设备；FFD ZigBee是ECHONET家庭网络连接中的一个节点，可以发送和接收信号，也可以转发和路由能力。当然，以上ECHONET家庭网络连接子系统中的各个子模块不一定同时具有。可以根据家庭电器的支持能力灵活配置。
4：云端数据库分析子系统；数据库访问子系统，设置为保存各种家用电器无线控制的无线码库信息。例如电视机的红外遥控码、空调的红外遥控码、智能电视的蓝牙控制码、或者电视盒子的无线wifi控制码等等。
当然本发明实施例中移动终端具备如手机等电子设备中必须有的通讯、显示、音频等子系统。这些子系统为任何智能移动终端所共有，在这里就不单独说明。
具有上述子系统的语音控制装置实现对智能家居的语音控制的原理如下：
步骤A：SensorHub低功耗待机检测子系统在移动终端待机模式下检测环境声音。此时移动终端的AP系统整体是处于省电待机状态，SensorHub本身由于是一个极低功耗的子系统，处于工作状态，时刻可以进行声音检测。这样就保证了移动终端可以已极低的待机功耗时时刻刻检测外界环境音。用户如果对智能移动终端说出用户语音指令。转到下一步；
步骤B：SensorHub低功耗待机检测子系统检测到了用户的语音口令，通知语音识别子系统。语音识别子系统的语音识别操作引擎对用户的语音指令进行识别，将语音指令转换为文字或字符指令。如果识别成功，则发送文本指令给语义分析识别操作引擎。如果识别失败，则无任何相应，重新转到步骤A继续已极低的待机功耗检测环境声音。在此步骤中，利用本文提供的方法很容易的实现了语音鉴权解锁功能。转到下一步；
步骤C：语义分析识别操作引擎接收到文本指令后，进行分析，此分析过程为根据文本指令在自己模块内部的服务器端进行搜索计算，根据用户的使用频次，精准匹配符合度等综合指标计算出最可能的用户语音指令，此指令中包含了用户的指令的关键词信息。最后根据模块间接口定义的接口格式将用户语音指令转换为接口指令输出发送给ECHONET家庭网络连接子系统。转到下一步；
步骤D：ECHONET家庭网络连接子系统根据用户的配置信息，判断用户所需要控制的电器对象是何种类型，当前支持所有可能的控制类型，包括：wifi、蓝牙、红外、ZigeBee等等。确定其中的一种类型。转到下一步；
步骤E：确定控制类型后，根据控制的类型云端数据库分析子系统搜索该品牌和型号下对于的无线控制码。如果正确找到匹配的码，则将码返回给ECHONET家庭网络连接子系统。转到下一步；
步骤F：移动终端根据上一步获得的无线控制码，通知ECHONET家庭网络连接子系统发送物理信号。发送物理信号，包括红外信号、wifi或蓝牙等无线信号。以此来控制对端的被控制电器。
ECHONET家庭网络连接子系统还可以加附加码发送无线控制码。
在本实施例中，可以通过ECHONET家庭网络连接子系统发送无线控制码之前，系统中在编码格式中添加具有本文标识特征的特殊字段。添加此字段对用户来讲是无任何体验感知的，但是通过仪器分析可以清楚的看出发送的红外码为本文特征码。
下面以红外编码格式进行举例说明：
请参考图12，图12为本实施例提供的红外编码格式示意图。
其中编码格式中，前9ms中黑色显示部分为消息头。此部分为固定。不可改变。后面的地址(Address)和命令(Command)区为消息体，这部分已经被电器厂商所配置，代表所控制电器的不同键值。中间有一段空白区，为自定义区，可以进行配置。例如，在本实施例中可以配置为0110或其他数值。
此外，对于语音鉴权过程，本实施例方案可以识别特定人的声音特征，从而做到只有经过鉴权识别通过的用户才可以进行操作控制的目的，让使用更加安全。其鉴权过程如下：
步骤A101：在一个相对安静的环境下说出指定的学习口令，例如可以是“芝麻开门”。用户说出这个口令。在相对安静的环境下说出口令的目的是减少环境噪声对学习的干扰。语音识别模块从用户发出的声音中对音频信号进行分析，提取出能量、基音频率、共振峰值语音参数。
步骤A102：为了提供学习的准确识别率需要进行二次学习以及三次学习。同样的需要用户在在一个相对安静的环境下说出相同的学习口令。同样的，语音识别模块从用户发出的声音中对音频信号进行分析，提取出能量、基音频率、共振峰值语音参数。语音特征参数可以是能量、基音频率、共振峰值等语音参数，目前在语音识别中较为常用的特征参数为线性预测倒谱系数(LPCC)与Mel倒谱系数(MFCC)。二者都是将语音从时域变换到倒谱域上，前者从人的发声模型角度出发，利用线性预测编码(LPC)技术求倒谱系数。后者则构造人的听觉模型，以语音通过该模型(滤波器组)的输出为声学特征，直接通过离散傅利叶变换(DFT)进行变换。
步骤A103：对三次学习得到的特征向量能量、基音频率、共振峰值语音 参数取加权平均得到最终的用户学习特征向量。学习完毕。
步骤A104：学习成功后，当用户在使用时就可以说出学习成功的用户自定义口令。如果当前说出的口令和学习成功的语音经过算法判断与步骤A103中得到的加权平均的最终特征向量相近，则可以直接唤醒系统并执行相应的命令。否则系统不给予相应。这就完成了语音识别的鉴权过程。根据语音识别子系统的支持能力，本方案中可以支持多条用户自定义的语音口令识别。
此外，本发明实施例还提供一种移动终端，该移动终端可以包括：上述实施例所述的语音控制装置，在此不再赘述。在本实施例中，移动终端接收用户语音指令，将语音指令转换为控制指令，在预置数据库中查找并获取与控制指令匹配的无线控制码和被控制电器的控制类型，向被控制电器发出控制信号，完成用户语音指令。当接收到用户对不同电器发出语音指令时，移动终端在预置数据库中查找并获取与当前被控制电器匹配的无线控制码和被控制电器的控制类型，实现在不切换控制模式的条件下，完成对不同电器的语音控制。因此，当用户需要使用电器时，不用根据被控制电器查找或更换相应的控制软件或者遥控终端，只需对移动终端发出语音口令，即可控制电器。
本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现上述方法。该存储介质包括如下任一种或几种：光盘、软盘、硬盘、和可擦写存储器等。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程序/指令来实现其相应功能。本发明实施例不限制于任何特定形式的硬件和软件的结合。
以上仅为本申请的优选实施例，并非因此限制本申请的保护范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间 接运用在其他相关的技术领域，均同理包括在本申请的保护范围内。
