本实施例根据上述方案，家电中设有音乐识别模型，家电在获取播放或待播放的音乐的音频信号后，通过音乐识别模型识别音频信号以确定音乐的类型，并根据类型确定音乐的音效，从而根据音效确定家电的播放装置的播放参数，以控制播放装置按照播放参数播放音乐。由于家电可以根据播放或待播放的音乐的类型调整家电上播放装置的播放参数，使得家电播放的音乐所呈现的音效为该音乐类型所对应的目标音效，家电的音乐播放效果较为丰富。
基于上述家电的硬件构架，提出本申请家电的控制方法的实施例。
参照图2，图2为本申请家电的控制方法的第一实施例，所述家电的控制方法包括以下步骤：
步骤S10，获取播放或待播放的音乐对应的音频信号；
；
在本实施例中，执行主体为家电。家电可以是空调器、电视机、电风扇等设备。家电上设有播放装置，播放装置可以为音箱。播放装置可用于播放音乐、读物以及家电的语音提示信息等。
家电可以通过网络连接音乐服务器，从而通过网络播放音乐播放传输的歌曲。当然，家电中也可存储音乐，存储的音乐可以是用户上传，也可以通过音乐服务器下载。也即家电可以通过本地存储或者从音乐服务器中获取待播放的音乐对应的音频信号。而在家电播放音乐时，从音乐的播放通道中按照设定的时间窗口录制音乐得到音频信号，也即家电通过播放通道中获取播放的音乐的音频信号。
家电会实时检测自身是否满足音效调整条件，若满足音效调整条件，家电则会确定播放或待播放的音乐的类型。音效调整条件包括接收到音效调整指令、家电所在空间的用户为预设用户以及家电处于音效调整模式中的至少一个。家电满足音效调整条件的时候，可以是家电正在播放音乐，例如家电播放音乐时，接收到音效调整指令；也可以是家电即将播放音乐，例如，家电启动播放装置时，接收到音效调整指令。
步骤S20，通过所述音乐识别模型识别所述音频信号以确定所述音乐的类型；
家电设有音乐识别模型。音乐识别模型通过一定数量级的不同类型的音乐的片段作为训练集训练得到。在家电播放音乐时，从音乐的播放通道中按照设定的时间窗口录制音乐得到音频信号，在将音频信号输入至音乐识别模型中，从而确定音乐的类型。而在音乐为待播放的音乐时，则从数据库中提取音乐对应的音频信息，根据音频信息转化为音频信号，并先将音频信号输入至音乐识别模型得到音乐识别模型输出的结果，该结果即为音乐的类型。当然，家电可以从音乐服务器中请求得到待播放的音乐的音频信号。
音乐识别模型包括声学模型以及语言模型，声学模型通过音乐的音色、音调、响度等信息训练得到，而语言模型则通过音乐的词训练得到。音频信号输入至音乐识别模型后，先提取音频信号的特征（可以是音乐的音色等特征），将特征输入至声学模型，声学模型将声学和发音学的知识进行整合，得到声学模型得分。提取的特征（音乐的词语、句子等）再输入至语言模型中，得到语言模型得分。可以理解的是，音乐识别模型所确定的每个音乐类型包括一个声学模型得分以及语言模型得分，音乐类型的总体分数最高即为输出的结果。通过声学模型以及语言模型能够更加准确的确定音乐的类型。
需要说明的是，家电在获取音频信号后，可对音频信号进行消除噪音、信道失真等处理，以将音频信号从时域转化到频域，从而为声学模型提取合适的特征。
音乐的类型可以是根据音乐的音色确定，例如，可以根据音乐的歌者的音色划分，也可以根据音乐所采用的乐器划分。音乐的类型也可以是根据音乐所表达的情绪确定，例如，将欢快的音乐确定为一类，将悲伤的音乐确定为一类。音乐的类型还可以是根据音乐的风格确定，例如，摇滚的音乐为一类，民谣的音乐为一类等。
步骤S30，根据所述类型确定所述音乐的音效；
家电中存储有类型与音效之间的映射关系表。在确定音乐的类型后，即可根据类型以及映射关系表查找音乐的音效。以音乐的风格确定的类型为例，举例如下：
音乐的类型 音效
摇滚 音效A
流行 音效B
爵士 音效C
蓝调 音效D
轻音乐 音效E
戏曲 音效F
步骤S40，根据所述音效确定所述家电的播放装置的播放参数，并控制所述播放装置按照所述播放参数播放所述音乐。
家电在确定音乐对应的音效后，即可确定音效对应播放装置的播放参数。播放参数可以是播放装置的音量、音频信号在功率放大器的功率、播放增益值。可以理解的是，播放参数为音量、功率或者播放增益值，家电会对音频信号在转换、传输、放大、播放过程中产生的失真进行合理有效的修正以及补偿。也即音效对应播放参数实际为一个补偿值。不同音效对应的补偿值不相同，因此，在确定音效后，确定音效对应的补偿值，再根据补偿值修正播放装置播放音乐待采用的播放参数，从而得到播放装置播放音乐实际所采用的播放参数。此外，播放参数还可以为音效模式，例如，立体环绕音效、数字音效等。
在确定播放参数后，家电即可控制播放装置按照确定的播放参数播放音乐，使得家电对播放出与音乐类型匹配的音效。
在本实施例提供的技术方案中，家电中设有音乐识别模型，家电在获取播放或待播放的音乐的音频信号后，通过音乐识别模型识别音频信号以确定音乐的类型，并根据类型确定音乐的音效，从而根据音效确定家电的播放装置的播放参数，以控制播放装置按照播放参数播放音乐。由于家电可以根据播放或待播放的音乐的类型调整家电上播放装置的播放参数，使得家电播放的音乐所呈现的音效为该音乐类型所对应的目标音效，家电的音乐播放效果较为丰富。
参照图3，图3为本申请家电的控制方法的第二实施例，基于第一实施例，所述步骤S40包括：
步骤S41，根据所述音效，确定所述播放装置播放所述音乐的各个音频段对应的播放参数；
步骤S42，在所述播放装置播放每个所述音频段时，控制所述播放装置按照播放的所述音频段对应的播放参数播放所述音乐。
音乐的音频信号包括多个音频段，音频段的频率区间的高低体现了音乐所表达的情绪。例如，音乐的类型为摇滚，音频段的频率区间越高，则该音频段所表达的情绪约为强烈，而音频段的频率区间越低，表明情绪处于压抑中。音频段的越低，则情绪压抑的越多，则在音频段较高的区域，压抑的情绪会爆发，因此，摇滚类型的音乐的低频的音频段可以适当降低音量，而高频的音频段可以适当增大音量，以体现摇滚音乐的先抑后扬的风格。音乐的类型不同，则音频段的增强以及削减的程度不同。例如，欢快的音乐的高频的音频段所对应的音量增量值可以小于摇滚的音乐的高频段所对应的音量增量值。可以理解的是，在本实施例中，播放参数包括音量。
音乐的音效可表征音乐的类型，因此，可以建立音效与各个音频段的播放参数的映射关系表。家电在确定音效后，确定该音效对应的映射关系表，从而确定播放装置在各个音频段所对应的播放参数。在播放装置播放音乐时，先确定播放音乐所对应的音频段，从而按照该音频段所对应的播放参数运行，播放装置在播放每个音频段时，控制播放装置按照播放的音频段所对应的播放参数播放音乐。
在本实施例提供的技术方案中，家电根据音效确定播放装置播放音乐的各个音频段对应的播放参数，并在播放装置播放每个音频段时，控制播放装置播放音频段所对应的播放参数，以合理的播放音乐。
参照图4，图4为本申请家电的控制方法的第三实施例，基于第一或第二实施例，所述步骤S40中根据所述音效确定所述家电的播放装置的播放参数包括：
步骤S43，获取所述家电所在环境的环境噪音；
步骤S44，根据所述环境噪音以及所述音效，确定所述播放装置的播放参数。
在本实施例中，家电可以获取环境噪音。环境噪音为背景噪音，也即环境噪音不包括音乐所产生的声音。若音乐为待播放音乐时，则获取噪音传感器采集的分贝值作为环境噪音，噪音传感器可以设置在播放音乐的家电上，也可以设置在其他家电，还可以独立设置在家电所在的房间。
若音乐为家电当前播放的音乐时，则确定家电播放音乐的开始时间点，从而从存储的环境声音中提取开始时间点对应的环境声音以作为环境噪音。
环境噪音越大，播放参数也应越大。对此，家电先根据音效确定播放装置的待确定播放参数，待确定播放参数可以为每个音频段对应的播放参数，待播放播放参数的确定方式可参照上述说明。家电在根据环境噪音对待确定播放参数进行修正，噪音越大，则修正的幅度也大，也即修正后的播放参数也越大。
在本实施例提供的技术方案中，家电获取自身所在环境的环境噪音，从而根据环境噪音以及音效准确的确定播放装置的播放参数。
参照图5，图5为本申请家电的控制方法的第四实施例，基于第一至第三的任一实施例，所述步骤S20包括：
步骤S21，获取所述音频信号对应的音乐参数；
步骤S22，通过所述音乐识别模型对所述音乐参数进行识别以确定所述音乐的类型。
在本实施例中，播放的音乐以及待播放的音乐具有对应的音乐参数，音乐参数可以是音频信号的音色、音调以及响度等声学特征。而音乐识别模型是通过音乐的音乐参数进行识别的。在本实施例提供的技术方案中，家电获取播放或待播放的音乐对应的音乐参数，从而根据音乐参数确定音乐的类型，进而根据类型准确的播放装置的播放参数。
在一实施例中，家电在获取播放或者待播放的音乐的音频信号后，先将音频信号输入音乐识别模型中，而音乐识别模型并不一定能够识别出音乐的类型。家电获取音乐识别模型输出的识别结果。识别结果中一般是包括有识别出的音乐的类型的。家电对识别结果进行分析，若是识别结果中包括音乐的类型的描述，则从识别结果中提取音乐的类型。若识别结果中不包括音乐的类型，例如，识别结果为无法识别音乐，家电则将音频信号发送至服务器，使得服务器对音频信号进行识别，从而确定音乐的类型。服务器再将音乐的类型反馈至家电。
在一实施例中，家电在播放调整音效的音乐时，会将音效对应的播放参数与音乐的音频信号进行关联存储，从而形成该音乐以及音乐的类型所对应的音效文件。也即在家电初次播放调整音效的音乐时，即可存储有该音乐以及音乐类型所对应的音效文件。对此，家电在确定音乐类型后，根据音乐的类型确定家电是否存储有音乐对应的音效文件，若存储有音效文件，则直接调取音效文件，以对该音效文件进行播放。若未存储有音效文件时，则执行步骤S40，也即确定播放装置的播放参数，从而控制播放装置按照播放参数播放音乐。
本申请还提供一种家电，所述家电包括音乐识别模型、存储器、处理器以及存储在所述存储器并可在所述处理器上运行的家电的控制程序，所述音乐识别模型与所述处理器连接，所述家电的控制程序被所述处理器执行时实现如上实施例所述的家电的控制方法的各个步骤。
本申请还提供一种计算机可读存储介质，所述计算机可读存储介质存储有家电的控制程序，所述家电的控制程序被处理器执行时实现如上实施例所述的家电的控制方法的各个步骤。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在如上所述的一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，空气调节设备，或者网络设备等)执行本申请各个实施例所述的方法。
