随着人们生活水平的日益提高，洗衣设备已经逐渐成为人们家中必备的家电之一。为了便于视力较差的用户群体设定洗涤设备的洗涤程序，现有洗涤设备大多设置有语音控制模块，使得用户能够通过语音指令控制洗涤设备洗涤衣物。
由于用户会根据每次洗涤衣物的不同具有多种洗涤需求，因此现有洗衣设备的洗涤程序模式以及每种洗涤程序模式对应的洗涤参数的种类均呈多样化设计。用户需要下达多条语音指令才能完成洗涤程序的设定，洗涤设备需要将获取到的语音指令与其语音库中存储的大量不同种类的设定指令进行对比才能识别获取的语音指令是否有效，从而导致了洗涤设备识别语音指令时的准确率较低且识别速度慢，延长了用户设定洗涤程序的时间，用户体验较差。
相应地，本领域需要一种新的用于洗涤设备的语音控制方法来解决上述问题。

附图说明

图2是本发明的用于洗涤设备的语音控制方法的优选实施方式的详细步骤流程图。
具体实施方式
需要说明的是，尽管本申请中按照特定顺序描述了本发明的控制方法的各个步骤，但是这些顺序并不是限制性的，在不偏离本 发明的基本原理的前提下，本领域技术人员可以按照不同的顺序来执行所述步骤。
基于背景技术中指出的现有洗涤设备识别语音指令时准确率较低且识别速度慢的问题，本发明提供了一种用于洗涤设备的语音控制方法，旨在减小洗涤设备每次获取语音指令时的识别范围，以便提高洗涤设备在识别语音指令时的识别准确率和识别速度。
首先参阅图1，图1是本发明的用于洗涤设备的语音控制方法的主要步骤流程图。如图1所示，本发明的用于洗涤设备的语音控制方法包括以下步骤：
S1：获取语音指令；
S2：根据语音指令选择性地切换当前操作界面。
在步骤S1中，“获取语音指令”具体为在洗涤设备显示当前操作界面时，获取用户发出的语音指令，此时，洗涤设备只需识别与当前操作界面的操作相关的语音指令即可满足洗涤设备当前的操控需求，也就是说，在洗涤设备只显示当前操作界面时，洗涤设备无需获取用户发出的、与除当前操作界面以外的其他界面相关的语音指令。
在步骤S2中，洗涤设备可以根据获取到的语音指令去判断是否进行切换当前操作界面的操作，以便用户能够通过语音指令切换当前操作界面，从而在完成与当前操作界面有关的设置内容后进入其他界面以分步完成洗涤设备的所有程序设定操作。
具体而言，步骤S2“根据语音指令选择性地切换当前操作界面”包括：
判断上述语音指令和预设切换指令是否匹配；
如果语音指令和预设切换指令匹配，则切换当前操作界面；
如果语音指令和预设切换指令不匹配，则不切换当前操作界面。
也就是说，洗涤设备的存储单元存储有一条或者多条与当前操作界面相关的预设切换指令，在获取到用户发出的语音指令后，洗涤设备将获取到的语音指令与预设切换指令进行比较，以判断是否 切换当前操作界面。其中，上述存储单元可以是设置于洗涤设备上的存储模块，如电脑板，还可以是与洗涤设备相连的云端等其他未设置于洗涤设备上的数据存储库。
在“如果语音指令和预设切换指令匹配，则切换当前操作界面”的步骤中，当洗涤设备识别到与预设切换指令匹配的语音指令时，如果洗涤设备只存储有一条与当前操作界面相关的预设切换指令，即切换当前操作界面后只能进入一个界面，则切换当前操作界面至该界面。如果洗涤设备存储有多条与当前操作界面相关的预设切换指令，即切换当前操作界面后具有多个可选择切换的界面，则将当前操作界面切换至与该语音指令对应的界面。
在“如果语音指令和预设切换指令不匹配，则不切换当前操作界面”的步骤中，不切换当前操作界面既可以包括继续显示当前操作界面，例如，继续显示当前操作界面并获取用户的语音信息直至将当前操作界面切换，还可以包括不显示当前操作界面，例如，在用户不发出语音信息时降低当前操作界面的亮度至黑屏效果以节约洗涤设备待机时消耗的能源。
作为示例，当前操作界面可为洗涤设备的洗涤模式设定界面。该洗涤模式设定界面上显示有多个洗涤模式，如混合洗、快速洗、强力洗、漂洗、单脱水等洗涤模式，其中，每个洗涤模式均对应一个参数设定界面，预设切换指令则包括与多个洗涤模式相对应的多条界面切换指令。在洗涤设备显示洗涤模式设定界面时，用户发出选定洗涤模式的语音指令，洗涤设备获取该语音指令并与多条界面切换指令对比。如果该语音指令与多条界面切换指令中的某一条相匹配，则将洗涤模式设定界面切换至该语音指令所选定的洗涤模式对应的参数设定界面，否则则不切换洗涤模式设定界面。
在一种优选的实施方式中，在不切换当前操作界面的情况下，本发明的语音控制方法还包括以下步骤：
判断上述语音指令中是否包含程序执行命令；
如果语音指令中包含程序执行命令，则根据程序执行命令选定当前操作界面上的程序并执行；
如果语音指令中不包含程序执行命令，则保持在当前操作界面并继续执行获取语音指令的步骤。
也就是说，在洗涤设备处于当前操作界面时，除了进行切换当前操作界面的操作以外，还可以直接选定当前操作界面上的程序并执行，无需进行进一步的设定。并且在用户发出的语音指令既不能切换当前操作界面又不能直接选定程序直接执行时，用户可通过多次发出语音指令的方式操控当前操作界面，洗涤设备能够重复获取并识别用户的语音指令，直至用户发出的语音指令有效、可控制洗涤设备进行切换界面或者选定并执行程序的操作。
在一种优选的实施方式中，“切换当前操作界面”的步骤包括：切换到参数设定界面；
本发明的语音控制方法还包括：
启动与当前待调节参数对应的计时程序；
获取语音参数调节命令；
如果在计时程序设定的时间内获取到匹配的语音参数调节命令，则调节当前待调节参数并启动与下一个待调节参数对应的计时程序。
在设定参数的步骤中，用户在每次计时时间内调节一个参数，在调节下一个参数时则会重新计时，并且当前的参数设定完毕后则同时开始进行下一次计时，用户可以在此计时过程中进行下一个参数的设定。需要说明的是，上述“当前待调节参数”和上述“下一个待调节参数”主要是指“用户当前想要设定的参数”和“用户下一个想要设定的参数”，两个待调节参数在该界面上可以是依次排列的也可以是乱序排列的。也就是说，在参数设定界面上具有多个参数时，用户可以根据需求以任意顺序逐个调节参数，无需依照各参数在界面上的排列顺序进行调节。在一种可能的情形下，多个参数均显示在参数设定界面，用户设定好的参数可以通过高亮显示、光圈显示等方式相对于未设定参数进行区分，其他未设定的参数则可以通过无特殊效果的显示方式或者闪烁显示等方式显示在该界面上。在另一种可能的情形下，参数设定界面上只显示各参数的类型名称而不显示具体参数， 在用户设定好当前参数时，界面上以数字显示的方式显示该参数的设定值，其他未设定的参数的值则不显示。
在上述实施方式中，用户能够通过选定洗涤模式的方式切换当前操作界面，并且界面切换后能够显示所选定的洗涤模式对应的参数设定界面，使得用户能够语音依次修改参数设定界面上的各个参数。在用户调节一个默认参数时，其他默认参数无需进行调节，使得洗涤设备在此时的语音识别范围被极大程度地缩小。
在切换当前操作界面的情况下，本发明的语音控制方法还包括以下步骤：
获取语音程序执行命令；
判断语音程序执行命令和预设程序执行命令是否匹配；
如果语音程序执行命令和预设程序执行命令匹配，则根据所述语音程序执行命令选定切换后的操作界面上的程序。
进一步地，本发明的语音控制方法还包括：
在根据语音程序执行命令选定切换后的操作界面上的程序的同时，直接执行选定的程序。
继续以用户设定洗涤程序为例，当用户在当前操作界面选定洗涤程序并切换界面后，用户能够看到该洗涤程序对应的参数设定界面，以便用户能够对选定的洗涤程序进行更细致的设定。此时，用户如果在看到上述参数设定界面后不继续进行洗涤参数的设定，则可直接通过发出语音程序执行命令的方式直接执行所选定的洗涤程序。例如，在洗涤设备显示参数设定界面时，用户发出“开始洗涤”的执行命令，则洗涤程序的设定过程结束，洗涤设备开始执行所选定的洗涤程序。
在用户切换当前操作界面后需要对所选定的洗涤程序进行更详细的设定时，优选地，本发明的语音控制方法还包括：在根据语音程序执行命令选定切换后的操作界面上的程序的同时，将界面切换至与所选定的程序对应的参数设定界面；
启动与当前待调节参数对应的计时程序；
获取语音参数调节命令；
如果在计时程序设定的时间内获取到匹配的语音参数调节命令，则调节当前待调节参数并启动与下一个待调节参数对应的计时程序；如果在计时程序设定的时间内未获取到匹配的语音参数调节命令，则将当前待调节参数设定为默认参数并启动与所述下一个待调节参数对应的计时程序。
在上述实施方式中，用户除了能够在参数设定界面上依次调节多个默认参数以外，还可以选择性的调节该多个参数中的部分参数，其中，不具有调节需求的参数可在计时结束后自动设定为默认参数。也就是说，在用户设定每个参数时，如果对该参数没有特殊要求，则只需等待计时程序设定的倒计时结束即可进行下一参数的设定，无需发出切换下一参数的语音指令，减少了洗涤设备的识别次数，提高了设定效率。
作为示例，参数设定界面上具有多个洗涤参数，如洗涤时间、洗涤水温、漂洗次数、脱水转速和附加功能等。每个洗涤参数对应若干调节项，如梯度递增的时间选项(10min、20min、30min……)、梯度递增的温度选项(20℃、30℃、40℃……)等。用户需要在计时程序设定的时间内发出与当前洗涤参数的多个调节项中的任一个相对应的语音参数调节指令，以选定当前的洗涤参数的调节项。若用户在计时结束之前发出匹配的语音调节指令，则当前洗涤参数完成设定，参数设定界面可以通过仅显示该洗涤参数的调节项或者将该参数选定的调节项加亮处理等方式突显当前设定好的洗涤参数，并在这一计时程序结束后同时使程序重新计时，以便用户进行下一个参数的设定。若用户在计时结束之前一直未发出语音调节指令，则当前洗涤参数在计时结束时会被自动设定为默认调节项，此时当前的洗涤参数的默认调节项被加亮显示以表示被选定，同时，下一计时程序启动，用户需要在重新计时的过程中进行上述类似的参数调节过程设定下一个想要设定的参数，直至参数设定页上的所有洗涤参数被以用户主动设定或者自动默认设定的方式被确定。当然，在用户设定完部分参数时，也可以通过直接启动洗涤程序的方式直接完成所有未设定参数的自动设定步骤(即在此次设定程序中，所有未设定的参数均设定为默认调节项)其中，每个洗涤参数的默认调节项可以根据用户每个洗涤模式下 最常用的一组洗涤参数进行设定；上述即使程序设定的时长可根据用户实际设定时的需求确定，例如，该时长可设定为5s至60s范围内的任一时长。
在一种可能的实施方式中，参数设定界面上还可以包括启动项，在用户调节参数的过程中，可通过语音指令随时控制启动项启动洗涤程序(此时没调节的参数均自动设定为默认参数)，以结束参数调节过程开始洗涤衣物。上述计时程序可以由具有倒计时功能的启动键执行。
优选地，本发明的语音控制方法还包括以下步骤：
在获取语音指令之前，获取语音唤醒指令；
判断语音唤醒指令与预设唤醒指令是否匹配；
若语音唤醒指令与预设唤醒指令匹配，则显示当前操作界面。
具体地，在洗涤设备通电待机且未被唤醒时，洗涤设备不显示当前操作界面。在用户发出唤醒洗涤设备的语音指令后，洗涤设备仅将该语音指令与预设唤醒指令进行匹配以识别用户的语音唤醒指令是否有效，并根据识别结果选择性地显示当前操作界面。
进一步地，为了防止用户在唤醒后洗涤设备后突然离开、不继续洗涤程序时洗涤设备消耗较多能源，本发明的语音控制方法还包括以下步骤：
在显示当前操作界面的情形下，获取没有收到语音指令的状态下当前操作界面的显示时长；
将显示时长与预设时长进行比较；
当显示时长和预设时长相等时，则关闭当前操作界面。
也就是说，在唤醒当前操作界面的情形下，当前操作界面的显示状态可以持续一段时间，如持续20s。在当前操作界面持续显示的时间长度到达预设时长时，当前操作界面由显示状态变为不显示状态，洗涤设备恢复至未被唤醒时的待机状态，以便用户在下次需要使用洗涤设备时重新对其进行唤醒。
根据上述实施方式，执行本发明的语音控制方法的洗涤设备具有多种操作情形：
在一种可能的情形中，用户发出语音指令唤醒洗涤设备后不继续进行其他操作，当前操作界面显示一端时间后关闭，洗涤设备恢复至未唤醒状态。
在一种可能的情形中，用户唤醒洗涤设备并在当前操作界面显示的这段时间内发出语音程序执行命令，当前操作界面上的某一洗涤程序被选中并以默认参数的方式执行该程序，当前操作界面不切换。
在一种可能的情形中，用户唤醒洗涤设备并在当前操作界面显示的这段时间内发出语音切换指令，当前操作界面根据语音指令被切换相应的参数设定界面，此时，用户不进行参数的设定直接启动该洗涤程序。
再参阅图2，图2是本发明的语音控制方法的优选实施方式的详细步骤流程图。如图2所示，在一种优选的情形中，用户需要选定洗涤程序并调节该洗涤程序对应的多个参数。此时，该情形下的详细步骤为：
S101：获取语音唤醒指令；
S102：判断语音唤醒指令与预设唤醒指令是否匹配；
S103：若语音唤醒指令与预设唤醒指令匹配，则显示当前操作界面，否则则返回步骤S101，直至获取到匹配的语音唤醒指令。
S104：获取语音指令；
S105：判断语音指令和预设切换指令是否匹配；
S106：判断语音指令中是否包含预设程序执行命令；
S107：如果语音指令中包含预设程序执行命令，则程序执行命令选定当前操作界面上的程序并执行，否则则继续显示当前操作界面并回到步骤S104。
S108：若语音指令和预设切换指令匹配，则选定切换后的操作界面上的程序的同时切换到参数设定界面；
S109：启动与当前待调节参数对应的计时程序；
S1010：获取语音参数调节指令；
S1011：判断在设定时间内是否获取到匹配的语音参数调节指令；
S1012：如果获取到匹配的语音参数调节指令，则调节当前待调节参数并同时启动与下一个待调节参数对应的计时程序；
S1013：如果未获取到匹配的语音参数调节指令，则使当前待调节参数设定为默认参数并同时启动与下一个待调节参数对应的计时程序。
重复上述参数设定步骤，调节完所有想要设定的参数后即可发出语音启动指令，使洗涤程序开始洗涤衣物。
最后需要说明的是，上述实施例均是本发明的优选实施方案，并不作为对本发明保护范围的限制。本领域技术人员在实际使用本发明时，可以根据需要适当添加或删减一部分步骤，或者调换不同步骤之间的顺序。这种改变并没有超出本发明的基本原理，属于本发明的保护范围。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
