Description

语音切换方法、电子设备及系统
本申请要求本申请要求于2018年10月09日提交中国国家知识产权局、申请号为201811172286.6、发明名称为“一种在智能音箱与智能手机间无缝切换语音通话和音频播放的方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及移动通信领域，尤其涉及一种语音切换方法、电子设备及系统。
背景技术
随着智能家居技术的发展，一个用户或家庭中往往具备多个能够互相通信的电子设备。例如，用户可使用同一个帐号登录手机以及家中的智能音箱、智能电视等电子设备，使得同一帐号下的多个电子设备组成一个局域网(local area network，LAN)，该局域网内的各电子设备之间均可通过服务器互相通信。
这样一来，用户可以根据实际需求选择使用局域网中的不同电子设备实现某一功能。例如，用户在家中时可以使用音箱从服务器中获取音频资源并播放，用户离开家时可以使用手机从服务器中获取音频资源并播放。
但是，当用户需要将音箱上播放的音频接续在手机上播放时，通常需要用户在音箱上停止播放正在播放的音频，并重新在手机中打开该音频继续播放。显然，这种在多个电子设备之间进行语音切换时的流程较为繁琐，在切换过程中正在播放的语音会发生中断，这样就使得电子设备之间切换音频播放的效率极大降低。
发明内容
本发明的目的在于申请提供了一种语音切换方法、电子设备及系统，可使得电子设备之间切换语音(例如VoIP通话或者音频播放)的效率提高哦，并提高用户体验。
上述目标和其他目标将通过独立权利要求中的特征来达成。进一步的实现方式在从属权利要求、说明书和附图中体现。
第一方面，提供一种语音切换的方法，可以包括：第二电子设备(例如智能音箱)检测到用户的语音输入；响应于上述语音输入，上述第二电子设备通过VoIP服务器与第三电子设备建立VoIP通话；第一电子设备(例如手机)向上述VoIP服务器发送第一切换请求信息，上述第一切换请求信息用于请求上述VoIP服务器将在上述第二电子设备上正在进行的上述VoIP通话切换到上述第一电子设备上；其中，上述第一切换请求信息中包括第一账号(例如HUAWEI-01)，上述第一账号用于登录到设备管理服务器；上述VoIP服务器接收到上述第一切换请求信息；响应上述第一切换请求信息， 上述VoIP服务器确定与上述第一帐号对应的VoIP业务的源设备为上述第二电子设备；上述VoIP服务器将在上述第二电子设备上正进行的上述VoIP通话切换到上述第一电子设备上。
在上述技术方案中，VoIP业务的源设备为智能音箱，VoIP业务的目标设备为手机。手机可向VoIP服务器发送第一切换请求信息，使得VoIP服务器将同一帐号下在智能音箱上正在执行的VoIP业务无缝切换到手机上。切换过程中不会发生VoIP业务中断的现象，用户也无需在多个设备之间反复操作，从而提高了多设备之间的语音切换效率和用户的使用体验。

具体实施方式
本申请以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的至少一个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参 考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。

Figure PCTCN2018125853-appb-000002
或者其它操作系统的便携式电子设备。上述便携式电子设备也可以是其它便携式电子设备，诸如具有触控面板或触敏表面的膝上型计算机(Laptop)等。还应当理解的是，在其他一些实施例中，上述电子设备也可以不是便携式电子设备，而是台式计算机。
下面将结合附图对本申请中各种实施例进行详细描述。
如图1所示，本申请一实施例提供一种语音切换系统100，该语音切换系统100可以包括一个或多个电子设备，例如第一电子设备(如图1中的电子设备101)和第二电子设备(如图1中的电子设备102)。其中，第一电子设备的具体结构，在后续实施例中将结合图2进行详细描述；第二电子设备的具体结构，在后续实施例中将结合图3进行详细描述。
如图1所示，电子设备101可以通过一个或多个网络109与电子设备102连接(例如有线或无线)。示例性地，该一个或多个通信网络109可以是局域网，也可以是广域网(wide area networks,WAN)例如互联网。该一个或多个通信网络109可使用任何已知的网络通信协议来实现，上述网络通信协议可以是各种有线或无线通信协议，诸如以太网、通用串行总线(universal serial bus,USB)、火线(FIREWIRE)、全球移动通讯系统(global system for mobile communications，GSM)、通用分组无线服务(general packet radio service，GPRS)、码分多址接入(code division multiple access，CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)、蓝牙、无线保真(wireless fidelity，Wi-Fi)、基于互联网协议的语音通话(Voice over Internet Protocol，VoIP)、或任何其他合适的通信协议。
上述语音切换系统100还可以包括设备管理服务器103，该设备管理服务器103用于管理注册的至少一个电子设备(如电子设备101和电子设备102)。示例性地，当电子设备101通过网络109向设备管理服务器103发送访问请求时，该设备管理服务器103可以对该电子设备进行鉴权(例如验证帐号、 密码是否匹配)；在鉴权通过后，该设备管理服务器103可以允许电子设备101访问设备管理服务器103上与之对应的数据例如存储空间等。又例如例如设备管理服务器103为电子设备(101,102)配置存储空间，这样电子设备(101,102)可以通过网络109将存储在电子设备(101,102)存储器中的数据(例如图片、视频等)发送给设备管理服务器103，再由设备管理服务器将接收到的数据保存在为电子设备(101,102)配置的储存空间中。示例性地，设备管理服务器103还可以通过网络109对电子设备(101,102)进行参数配置。
其中，帐号可以是指电子设备登录到设备管理服务器103所使用的凭证。电子设备(101,102)需要使用一个帐号登录到设备管理服务器103，才能使用电子设备的一些功能，例如电子设备需要登录帐号，才能使用指纹识别、联系人同步、找回手机等功能，在没有登录帐号的情况下，无法使用上述功能。当用户在电子设备上输入帐号及密码进行登录时，验证信息可以通过网络109发送给设备管理服务器103进行验证。可以理解的是，由于上述设备管理服务器主要是用于对电子设备的帐号进行鉴权，因此该云服务器可以知道哪些电子设备登录了同一个帐号。
在一些实施例中，电子设备101和电子设备102可以是属于同一个用户108的两个不同的电子设备。例如托马斯有一部智能手机，还有一个语音助理设备(例如智能音箱)；其中，该智能语音设备配置有语音助理系统(以下实施例中对给语音助理系统有详细说明)，该语音助理设备可以接收用户的语音输入并对该语言输入进行分析等功能。这两个电子设备都可以使用托马斯所拥有的帐号(例如HUAWEI-01)访问设备管理服务器103。设备管理服务器103可以管理各个帐号和使用该帐号访问的电子设备之间的访问权限；另外，同一个帐号也可在设备管理服务器103所管理的2个或2个以上的电子设备上同时登录。这样，登录同一帐号的第一电子设备(例如电子设备101)和第二电子设备(例如电子设备102)可通过设备管理服务器103实现数据交互等。可以理解的是，该用户108可以通过其他电子设备使用上述帐号登录到设备管理服务器103中，并对存储在其上的电子设备的访问权限进行调整，例如删除电子设备101使用帐号HUAWEI-01登录的权限，或，增加另一电子设备使用上述帐号登录的权限等。
示例性地，表1中是存储在设备管理服务器103中的一些与登录的电子设备相关的信息。从中可以看到，有两个电子设备(设备名称为手机101、智能音箱102)使用同一帐号(HUAWEI-01)登录到了设备管理服务器103中。这两个电子设备登录设备管理服务器103时可以携带有各自的设备标识(例如表1中的IMEI)，或者设备管理服务器103在电子设备登录后，向这些电子设备请求其对应的设备标识，以便后续对这些电子设备进行管理。上述设备标识用于唯一标识电子设备，以便网络中的其他电子设备或者服务器辨识它们。常见的设备标识包括国际移动设备身份码(international mobile equipment identity，IMEI)、国际移动用户识别码(international mobile subscriber identification number，IMSI)、移动设备识别码(mobile equipment identifier，MEID)、序列号(serial number，SN)、集成电路卡识别码(Integrate circuit card identity，ICCID)、以及媒体介入控制层(media access control，MAC)地址或其他能够唯一标识电子设备的标识符等。这样，设备管理服务器103就可以通过不同的设备标识来识别不同的电子设备，尽管这些电子设备是以同一个帐号登录的。

表1
在一些实施例中，电子设备101(例如手机101)可以通过上述网络109与电子设备107(例如手机107)进行语音通信例如VoIP通话。其中，电子设备107可以使用第二账号(例如表1中的HUAWI-02)登录到设备管理服务器103中。
在一些实施例中，上述语音切换系统100还可以包括语音助理服务器105。语音助理服务器105可以通过上述网络109与外部服务(例如流媒体服务、导航服务、日历服务、电话服务、照片服务等)进行通信以完成任务或采集信息。上述语音助理服务器105可以是语音助理系统(图中未示出)的一部分，该语音助理系统可以根据客户端-服务器模型来实现。示例性地，该语音助理系统可以包括在电子设备(例如如图1中的电子设备102)上执行的客户端侧部分(例如语音助理客户端)，以及在语音助理服务器105上执行的服务器侧部分(例如语音助理系统)。语音助理客户端可以通过上述网络109与语音助理系统进行通信。语音助理客户端提供客户端侧功能诸如面向用户的输入和输出处理以及与服务器侧的语音助理系统的通信。语音助理系统可以为一个或多个语音助理客户端提供服务器侧功能，该一个或多个的语音助理客户端各自位于相应的电子设备上(例如电子设备101和电子设备102)。
示例性地，如图1所示的第一电子设备(如电子设备101)可以为手机101，第二电子设备(如电子设备102)可以为语音助理设备例如智能音箱102。
在一些实施例中，手机101和智能音箱102均可具有语音通信功能。例如，手机101和智能音箱102可提供VoIP业务。那么，如图1所示，语音切换系统100中还可以包括VoIP服务器104。VoIP服务器104可用于实现VoIP业务的呼叫、接听、三方通话以及呼叫转移等与语音通信相关业务。这样，手机101(或智能音箱102)可通过VoIP服务器104与其他具有语音通信功能的电子设备进行语音通信。
在一些实施例中，语音助理服务器105可以向VoIP服务器104提供语音识别结果。示例性地，用户108向智能音箱102输入“打电话给约翰”的语音信号后，智能音箱102可将采集到的该语音信号发送给语音助理服务器105进行语音识别。语音助理服务器105识别出与上述语音信号对应的控制指令为：呼叫联系人约翰。进而，语音助理服务器105可向VoIP服务器104发送呼叫联系人约翰的指令。响应于该指令，VoIP服务器104可向约翰的电子设备(例如手机)发起语音呼叫请求，当约翰接受该语音呼叫请求后便可建立智能音箱102与约翰的手机之间的语音通话，实现VoIP业务。
在另外一些实施例中，如图1所示，上述语音切换系统100中还可以包括内容服务器106。该内容服务器106可用于根据用户108的请求向智能音箱102(或手机101)提供音乐、视频等流媒体内容。例如，用户108在向智能音箱102发出“播放歌曲Silence”的语音信号后，智能音箱102可将采集到的该语音信号通过网络109发送给语音助理服务器105进行语音识别。语音助理服务器105识别出与上述语音信号对应的控制指令为：获取歌曲Silence的媒体资源。进而，语音助理服务器105可向内容服务器106发送请求信息，以获取歌曲Silence的媒体资源。响应于语音助理服务器105发送的请求信息，内容服务器106查找到歌曲Silence的媒体资源后可将该播放地址返回给语音助理服务器105，并由语音助理服务器105将该媒体资源发送给智能音箱102，使得智能音箱102根据该媒体资源获取歌曲Silence的地址并播放或者保存。
当然，手机101(或智能音箱102)也可以通过网络109与内容服务器106直接进行交互。示例性地，手机101(或智能音箱102)可以根据用户108的输入，向内容服务器106发送播放歌曲Silence的请求信息；内容服务器106在接收到上述请求信息后，查找到歌曲Silence的媒体资源，然后可将该媒体资源返回给手机101(或智能音箱102)；手机101(或智能音箱102)根据收到的该媒体资源获取歌曲Silence的地址并播放，也可以将该歌曲保存在手机101的存储器中或智能音箱102的存储器中。
在其他一些实施例中，手机101与智能音箱102登录同一帐号后，当手机101执行语音通话业务(例如上述VoIP业务)时，如果用户108希望将此时的语音通话业务切换到智能音箱102上，则用户108可在手机101或智能音箱102上做一个预设的特定操作，诸如特定手势或语音输入等，从而触发VoIP服务器104将手机101上的语音通话业务切换至智能音箱102，以便该语音通话业务继续在智能音箱102上进行。相应的，当智能音箱102正在执行语音通话时，用户108也可在手机101或智能音箱102上做一个预设的特定操作，以触发VoIP服务器104将智能音箱102上的语音通话业务切换至手机101，以便该语音通话业务继续在手机101上进行。也就是说，在上述实施例中，用户108只需对电子设备做上述特定操作，VoIP服务器104便可将正在进行的语音通话业务从第一电子设备自动切换到第二电子设备中。这样一来，整个切换过程中不会发生语音通话业务中断的现象，用户也无需在多个电子设备之间反复操作，从而提高了多个电子设备之间的语音切换效率和用户的使用体验。
在另一些实施例中，当手机101与智能音箱102登录同一帐号(例如HUAWEI-01)后，当手机101正在播放音频/视频时，如果用户108希望将该播放的音频/视频切换(例如无缝切换)到智能音箱102上继续播放，用户108可在手机101或智能音箱102上做一个预设的输入操作，从而触发内容服务器106将手机101上正在播放的音频/视频业务切换至智能音箱102上继续播放。同样的，当智能音箱102执行音频/视频业务时，用户108也可在手机101或智能音箱102上做一个预设的输入操作，以触发内容服务器106将智能音箱102上正在播放的音频/视频切换至手机101上继续播放。
需要说明的是，第一电子设备除了可以是手机101外，还可以是平板电脑、具备无线通讯功能的可穿戴电子设备(如智能手表)、虚拟现实设备等支持音频/视频业务或语音通话业务的电子设备，以下实施例中对第一电子设备的具体形式不做特殊限制。第二电子设备除了智能音箱102外，还可以为智能电视、平板电脑、笔记本电脑、台式计算机等支持音频/视频业务的电子设备，以下实施例中对第二电子设备的具体形式不做特殊限制。在一些实施例中，第一电子设备可以是手机，那么，第二电子设备可以是配置有语音助理系统的智能音箱或笔记本电脑。

在一些实施例中，处理器110可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。其中，USB接口130是符合USB标准规范的接口，具体可以是Mini USB接口，Micro USB接口，USB Type C接口等。USB接口130可以用于连接充电器为电子设备101充电，也可以用于电子设备101与外围设备之间传输数据。也可以用于连接耳机，通过耳机播放音频。
可以理解的是，本发明实施例示意的各模块间的接口连接关系，只是示意性说明，并不构成对电子设备101的结构限定。在本申请另一些实施例中，电子设备101也可以采用上述实施例中不同的接口连接方式，或多种接口连接方式的组合。
充电管理模块140用于从充电器接收充电输入。其中，充电器可以是无线充电器，也可以是有线充电器。在一些有线充电的实施例中，充电管理模块140可以通过USB接口130接收有线充电器的充电输入。在一些无线充电的实施例中，充电管理模块140可以通过电子设备101的无线充电线圈接收无线充电输入。充电管理模块140为电池142充电的同时，还可以通过电源管理模块141为电子设备101供电。

在一些实施例中，通过使用处理模块(例如I/O处理模块321F、STT处理模块321G、自然语言处理模块321H、对话流处理模块321I、任务流处理模块321J或服务处理模块321K)、数据以及在语音助理模块321E中实现的模型，语音助理设备300可以执行以下操作中的至少一种:识别从用户接收的自然语言输入中所表达的用户的意图；积极地引出并获得用于充分推断用户的意图所需的信息(例如，通过消除字词、名称、意向等的歧义)；确定用于实现推断出的意图的任务流(task flow)；以及执行任务流以实现推断出的意图。在另外一些实施例中，当由于各种原因而未向或不能向用户提供令人满意的响应时，语音助理设备300也采取其他适当的行动。
在一些实施例中，I/O处理模块321F可以通过一个或多个麦克风阵列370B接收用户的命令(例如语音命令)或者输入(例如语音输入)；I/O处理模块321F也可以通过I/O接口351从所连接的其他设备(例如麦克风、触摸屏或键盘等)中接收来自用户的命令或输入；I/O处理模块321F还可以通过一个或多个扬声器阵列370A或者指示器392或显示屏394等提供对用户输入的响应，从而与用户进行交互；I/O处理模块321F还可以通过网络通信接口350与其他电子设备(例如图2中的电子设备101)交互以获得用户输入(例如语音输入)并提供对用户输入的响应。I/O处理模块321F可以在接收到用户输入时或在接收到用户输入之后不久，获得与来自其他电子设备的用户输入相关联的上下文信息。上下文信息包括特定于用户的数据、词汇，或与用户输入相关的偏好。在另一些实施例中，上下文信息还可以包括在接收到用户请求时电子设备(例如电子设备101)的软件和硬件状态，或与在接收到用户请求时用户的周围环境相关的信息。在一些实施例中，I/O处理模块321F还向用户发送与用户请求有关的跟进问题，并从用户接收回答。在一些实施例中，当用户请求被I/O处理模块321F接收到且用户请求包含语音输入时，I/O处理模块321F可以将该语音输入转发至STT处理模块321G以进行语音文本转换。
在一些实施例中，STT处理模块321G通过I/O处理模块321F接收语音输入。STT处理模块321G可以使用各种声音模型和语言模型来将语音输入识别为音素的序列，并最终将其识别为以一种或多种语言书写的字词(words)或符号(tokens)的序列。STT处理模块321G可以使用任何合适的语音识别技术、声音模型以及语言模型，诸如隐马尔可夫模型、基于动态时间规整的语音识别以及其他统计或分析技术，来加以实施本申请实施例。在一些实施例中，语音转文本处理可至少部分地由第三方服务执行或在电子设备上执行。一旦STT处理模块321G获得语音转文本处理的结果(例如字词或符号的序列)，它便将结果传送至自然语言处理模块321H以进行意图推断。
自然语言处理模块321H(也可称之为自然语言处理器)得到由STT处理模块321G生成的字词或符号的序列(“符号序列”)，并尝试将该符号序列与由语音助理模块321E所识别的一个或多个“可执行 意图(actionable intents)”相关联。“可执行意图”表示可由语音助理模块321E执行的任务，并且具有在任务流模型中实施的相关联任务流。相关联任务流是语音助理模块321E为了执行任务而采取的一系列经编程的动作和步骤。语音助理系统的能力范围取决于已在任务流模型中实现并存储的任务流的数量和种类；或换言之，取决于语音助理模块321E所识别的“可执行意图”的数量和种类。然而，语音助理系统300的有效性还取决于语音助理模块321E从以自然语言表达的用户请求中推断出正确的“一个或多个可执行意图”的能力。
在一些实施例中，除从STT处理模块321G获得的字词或符号的序列之外，自然语言处理模块321H还可以接收与用户请求相关联的上下文信息(例如，来自I/O处理模块321F)。自然语言处理模块321H还可以使用上下文信息来明确、补充和或进一步定义在从STT处理模块321G接收的符号序列中包含的信息。上下文信息包括例如用户偏好、用户设备的硬件和/或软件状态，在用户请求之前、期间或之后不久收集的传感器信息，语音助理系统与用户之间的先前交互(例如对话)，等等。
在一些实施例中，自然语言处理模块321H具体可以包括知识本体(ontology)、词汇、用户数据和分类模块。其中，知识本体为包含多个节点的分级结构，每个节点表示与“可执行意图”或其他“属性”中的一者或多者相关的“可执行意图”或“属性”。如上所述，“可执行意图”表示语音助理系统300能够执行的任务(例如可执行或可被进行的任务)。“属性”代表与可执行意图或另一属性的子方面相关联的参数。知识本体中的每个节点，与跟由节点所代表的属性或可执行意图有关的一组字词和/或短语相关联。与每个节点相关联的相应的字词和/或短语是所谓的与节点相关联的“词汇”。与每个节点相关联的相应的一组字词和/或短语，可存储在与由节点所表示的属性或可执行意图相关联的词汇索引中。词汇索引可以包括不同语言的字词和短语。在一些实施例中，自然语言处理器321H接收来自STT处理模块321G的符号序列(例如文本串)，并且确定符号序列中的字词牵涉哪些节点。
用户数据包括特定于用户的信息，诸如特定于用户的词汇、用户偏好、用户地址、用户的默认语言和第二语言、用户的联系人列表，以及每位用户的其他短期或长期信息等。自然语言处理器321H可使用用户数据来补充用户输入中所包含的信息以进一步限定用户意图。例如，针对用户请求“邀请我的朋友参加我的生日派对”，自然语言处理器321H能够访问用户数据以确定“朋友”是哪些人以及“生日派对”将于何时何地举行，而不需要用户在其请求中明确地提供此类信息。
自然语言处理器321H还可以包括分类模块。在一些实施例中，分类模块确定例如文本串中一个或多个词语中的每个词语是否均为实体、活动或位置中的一者。一旦基于用户请求识别出可执行意图，自然语言处理器321H便生成结构化查询以表示所识别的可执行意图。在一些实施例中，自然语言处理器321H可以用所接收的上下文信息来填充结构化查询的一些参数。例如，如果用户请求“我附近的”寿司店，则自然语言处理器321H可用来自语音助理设备300的GPS坐标来填充结构化查询中的位置参数。
在一些实施例中，自然语言处理器321H将结构化查询传送至任务流处理模块321J(也可称为任务流处理器)。任务流处理器321J被配置为执行以下中的一个或多个:从自然语言处理器321H接收结构化查询，完成结构化查询，以及执行用户的最终请求所需的动作。在一些实施例中，完成这些任务所必需的各种过程在任务流处理模块321J中的任务流模型中提供。任务流模型包括用于获取来自用户的附加信息的过程，以及用于执行与可执行意图相关联的动作的任务流。如上所述，为了完成结构化查询，任务流处理器321J可能需要发起与用户的附加对话，以便获得附加信息，和/或消除可能模糊的话语的歧义。当此类交互有必要时，任务流处理器321J调用对话处理模块321I(也可称为对话 处理器)以进行与用户的对话。在一些实施例中，对话处理模块321I确定如何(和/或何时)向用户询问附加信息，并接收和处理用户的响应。在一些实施例中，通过I/O处理模块351将问题提供给用户并从用户接收回答。例如，对话处理模块321I经由扬声器阵列370A和/或显示屏394向用户呈现对话输出，并接收来自用户的输入。
在一些实施例中，对话处理器321I可以包括消歧模块。消歧模块用于消除一个或多个模糊词语(例如，对应于与数字照片相关联的语音输出的文本串中的一个或多个模糊词语)的歧义。在一些实施例中，消歧模块识别出一个或多个词语中的第一词语具有多个候选含义，提示用户关于第一词语的附加信息，响应于提示接收来自用户的附加信息并且根据附加信息来识别与第一词语相关联的实体、活动或位置。
一旦任务流处理器321J已针对可执行意图完成结构化查询，任务流处理器321J就继续执行与可执行意图相关联的最终任务。因此，任务流处理器321J可以根据结构化查询中包含的特定参数来执行任务流模型中的步骤和指令。在一些实施例中，任务流处理器321J在服务处理模块321K(也可称为服务处理器)的辅助下完成用户输入中所请求的任务，或者提供用户输入中所请求的信息性回答。例如，服务处理器321K可代替任务流处理器321J发起电话呼叫、设置日历条目、调用地图搜索、调用用户设备上安装的其他应用程序或与这些其他应用程序交互，以及调用第三方服务(例如，餐厅预订门户网站、社交网站或服务、银行门户网站等)或与这些第三方服务交互。在一些实施例中，可通过服务处理模块321K中服务模型中的相应服务模型指定每项服务所需的协议和应用程序编程接口(application programming interface,API)。服务处理器321K针对服务访问适当的服务模型，并依据服务模型根据该服务所需的协议和API生成针对该服务的请求。
在一些实施例中，自然语言处理器321H、对话处理器321K以及任务流处理器321J共同且反复地使用以推断并限定用户的意图、获得信息以进一步明确并提炼用户意图、并最终生成响应(例如，将输出提供至用户，或完成任务)以满足用户的意图。在一些实施例中，在已执行满足用户请求所需的所有任务之后，语音助理系统制定确认响应，并通过I/O处理模块321F将该响应发送回用户。如果用户请求寻求信息性回答，则确认响应向用户呈现所请求的信息。
在另一些实施例中，I/O接口351可以将语音助理设备300的I/O设备诸如键盘、触摸屏、麦克风等耦接至用户界面模块321C。I/O接口351与用户界面模块321C结合接收用户输入(例如，语音输入、键盘输入、触摸输入等)并相应地对这些输入进行处理。
可以理解的是，上述第二电子设备可以跨多个计算机分布，从而形成一个客户端-服务器的语音助理系统。在该语音助理系统中，语音助理系统的模块和功能中的一些被划分成服务器部分和客户端部分。其中客户端部分可以位于第二电子设备(例如电子设备102)上，并通过网络109与服务器部分(例如语音助理服务器105)通信，如图1中所示。在一些实施例中，语音助理系统可以为图1中所示的语音助理服务器105的实施例。在另一些实施例中，语音助理系统可以在电子设备102中实现，从而消除了对客户端-服务器系统的需求。应当指出，上述语音助理系统仅为一个实例，并且该语音助理系统可具有比示出的更多或更少的部件、可组合两个或更多个部件、或可具有部件的不同配置或布局。

以下将结合实施例的具体场景阐述如何在手机101和智能音箱102之间切换VoIP业务。
在一些应用场景中，用户108在手机101和智能音箱102上使用同一帐号登录设备管理服务器103后，用户10可通过智能音箱102与其他电子设备(例如图1中的电子设备107)进行VoIP业务。如果用户108希望将该VoIP业务从智能音箱102切换至手机101上，用户可在手机101上执行预设的输入操作，以触发VoIP服务器104通过网络109将智能音箱102上正在进行的VoIP业务切换至手机101上。
示例性的，如图4所示，本实施例提供一种语音切换方法，该方法可以在上述实施例中所涉及的电子设备、服务器中实现，可以包括如下步骤：
步骤S401：手机101和智能音箱102均使用第一帐号登录到设备管理服务器103。
其中，上述第一帐号(例如HUAWEI-01)可以是某一应用(例如酷狗音乐)的帐号，也可以是某一服务(例如华为云服务)的帐号。
例如，如果手机101和智能音箱102中均安装有酷狗音乐这个APP，那么，用户108可在手机101的酷狗音乐APP中使用帐号(HUAWEI-01)登录该APP对应的设备管理服务器103；并且，用户108也可在智能音箱102的酷狗音乐APP中使用同一帐号(HUAWEI-01)登录该APP对应的设备管理服务器103。又例如，如果手机101和智能音箱102均为华为品牌的电子设备，则手机101和智能音箱102均可向用户108提供华为云服务。那么，用户可在手机101中使用帐号(HUAWEI-01)登录华为云服务的设备管理服务器103，并且，用户108也可在智能音箱102中使用同一帐号(HUAWEI-01)登录华为云服务的设备管理服务器103。
设备管理服务器103中保存有帐号以及用该用帐号登录的电子设备的设备信息例如设备标识(如表1中所示)。当手机101和智能音箱102均使用同一帐号登录设备管理服务器103后，设备管理服务器103可建立第一帐号与使用第一帐号的电子设备之间的对应关系。这样，在设备管理服务器103中就可以查询到在某一帐号下登录的电子设备具体有哪些。
步骤S402：智能音箱102检测到用户108发起语音通话的输入操作。
步骤S403：响应于上述输入操作，智能音箱102通过VoIP服务器104建立与第三电子设备(例如图1所示的手机107)之间的VoIP通话。
示例性地，如果用户108需要使用VoIP业务与联系人(例如苏珊)通话，用户108可在智能音箱102上发起VoIP语音通话的输入操作。该输入操作具体可以是用户108在智能音箱102的显示屏394上输入苏珊的电话号码的操作。
在另一些实施例中，该输入操作也可以是用户108向智能音箱102进行的语音输入操作。例如，用户108可以对着智能音箱102说“给苏珊打电话”。智能音箱102采集到该语音信号后，可利用智能音箱102中的语音助理系统对该语音信号进行语音识别，得到与该语音信号对应的控制指令。例如，上述语音助理系统根据上述语音信号识别出控制指令为“呼叫联系人苏珊”。进而，智能音箱102可根 据通讯录中苏珊的电话号码，向VoIP服务器104发送呼叫该电话号码的呼叫请求，使得VoIP服务器104呼叫联系人苏珊的手机107。后续，如果被呼叫的手机107成功接听了智能音箱102发起的呼叫，则手机107可向VoIP服务器104发送成功接听的消息，从而建立智能音箱102与被呼叫方(即联系人苏珊的手机107)之间的VoIP通话。这样，用户可使用智能音箱102与联系人进行VoIP通话。
可以理解的是，本申请各个实施例中，智能音箱102是可以通过一个或多个麦克风阵列370B来从不同方位采集用户的语音输入(也即语音信号)，智能音箱102是可以通过一个或多个扬声器阵列370A来播放语音助理系统对语音识别结果的语音反馈。
在一些实施例中，智能音箱102采集到用户的语音信号后，也可以将该语音信号发送给语音助理服务器105，由语音助理服务器105对该语音信号进行语音识别，得到与该语音信号对应的控制指令。当识别出的控制指令与VoIP业务相关时，语音助理服务器105可将识别出的控制指令发送给VoIP服务器104，由VoIP服务器104按照上述方法建立智能音箱102与被呼叫方之间的VoIP业务。当然，用户除了通过输入语音信号发起VoIP业务的呼叫操作外，还可以通过执行预设的手势等方式发起VoIP业务的呼叫操作，本申请实施例对此不做任何限制。
步骤S404：手机101向VoIP服务器104发送第一切换请求信息，该第一切换请求信息用于请求VoIP服务器104将智能音箱102中正在进行的VoIP业务切换到手机101上继续进行。
在一些实施例中，该第一切换请求信息中可以包括第一帐号。
在一些应用场景下，用户可能希望将上述智能音箱102中正在进行的VoIP通话切换到手机101上执行。例如，智能音箱102位于用户108的家中，用户在家中时可以使用智能音箱102与其他电子设备(例如手机107)进行VoIP通话。当用户离开家时，用户需要使用便携性更好的手机101继续与手机107进行VoIP通话。此时，用户需要将智能音箱102中正在执行的VoIP业务切换到手机101上继续执行。
为了实现VoIP业务在手机101和智能音箱102之间的切换功能，手机101可以预先设置一个用于切换VoIP业务的特定操作。示例性地，该特定操作可以为翻转手机、指关节敲击屏幕、双击电源键或滑动操作等输入操作。或者，该特定操作也可以为预设的语音输入。例如，用户108可以向手机101语音输入“切换语音通话”的语音指令。可以理解的是，本领域技术人员可根据实际应用场景或实际经验设置该预设操作，本实施例对此不做任何限制。
那么，当手机101检测到用户对手机101的一输入操作时，手机101如果确定该输入操作是上述特定操作，则响应于确定上述特定操作，手机101可向VoIP服务器104发送第一切换请求信息。
换句话说，当手机101检测到上述特定操作时，说明用户101此时需要将第一帐号(例如HUAWEI-01)下正在进行的VoIP业务切换到手机101上。进而，响应于该特定操作，手机101可通过网络109向VoIP服务器104发送第一切换请求信息。
示例性的，可以预先设置上述特定操作为在手机101的触摸屏上的一滑动手势。例如，当滑动手势的滑动轨迹为X型时，该滑动手势用于指示将手机101上正在进行的VoIP通话切换至用户的智能音箱102上，手机101可将智能音箱102作为VoIP通话的目标设备。当滑动手势的滑动轨迹为Y型时，该滑动手势用于指示将手机101上正在进行的VoIP通话切换至用户的平板电脑111(图中未示出)上。 那么，如果检测到用户执行的滑动操作的滑动轨迹为X形，则手机101可将平板电脑111作为VoIP通话的目标设备。
在另一些实施例中，上述第一切换请求信息中还可以包括手机101在VoIP业务中的VoIP标识(例如手机101的电话号码或IP地址等)，和智能音箱102在VoIP业务中的VoIP标识。
在一些实施例中，上述第一切换请求信息中还可以包括手机101的设备标识，以使得VoIP服务器104在接收到上述第一切换请求信息后，对电子设备101进行合法性验证。这样就进一步提高了语音切换的安全性。
在其他一些实施例中，手机101还可以根据检测到的特定条件，自动通过网络109向VoIP服务器104发送上述第一切换请求信息，而不需要上述实施例中用户向手机101输入一个特定操作来触发。
在一些实施例中，上述特定条件可以是WLAN网络中的Wi-Fi信号强度。示例性的，手机101与智能音箱102均接入到了同一个Wi-Fi网络，也即这两个电子设备都可以使用WLAN网络中的同一个服务集标识(service set identifier，SSID)来访问网络。由于手机101相对于智能音箱102的便携性更好，因此，当手机101与智能音箱102接入同一Wi-Fi网络(例如SSID名称为“123”的Wi-Fi网络)时，手机101可以根据检测到的该Wi-Fi网络的Wi-Fi信号强度的变化，确定是否向VoIP服务器104发送上述第一切换请求信息。例如，当手机101无法检测到上述网络的Wi-Fi信号或者检测到的Wi-Fi信号低于一预设阈值时，手机101可自动向VoIP服务器104发送上述第一切换请求信息。上述情况说明用户此时已经携带手机101远离了上述Wi-Fi网络，也远离了智能音箱102。在这种情况下，手机101可以请求VoIP服务器104将在智能音箱102中正在进行的VoIP通话切换至手机101，这样用户就可以方便地在手机101继续进行VoIP通话了。
在另一些实施例中，上述特定条件也可以是蓝牙信号强度。示例性地，手机101与智能音箱102之间可建立蓝牙连接，这样，手机101可以根据检测到的手机101与智能音箱102之间蓝牙信号强度，确定是否向VoIP服务器104发送上述第一切换请求信息。例如，当手机101检测到与智能音箱102之间的蓝牙连接断开，或者，当手机101检测到智能音箱102的蓝牙信号强度小于一预设阈值时，手机101可自动向VoIP服务器104发送上述第一切换请求信息。上述情况说明用户此时已经携带手机101远离了智能音箱102。在这种情况下，手机101可以请求VoIP服务器104将在智能音箱102中正在进行的VoIP通话无缝切换至手机101，这样用户就可以方便地在手机101继续进行VoIP通话了。
需要说明的是，本领域技术人员可以根据实际应用场景或实际经验设置触发手机101向VoIP服务器104发送第一切换请求信息的其他技术方案，本申请实施例对此不做任何限制。例如，手机101可以与dock设备通过有线方式连接，并通过dock设备与智能音箱102连接，当检测到手机101从该dock设备拔出时，响应于该事件，手机101可自动通过网络109向VoIP服务器104发送上述第一切换请求信息。
步骤S405：VoIP服务器104接收到手机101发送的上述第一切换请求信息。
步骤S406：响应于接收到上述第一切换请求信息，VoIP服务器104确定与上述第一帐号对应的VoIP业务的源设备为智能音箱102。
示例性地，VoIP服务器104接收到手机101通过网络109发送来的第一切换请求信息后，可向设备管理服务器103发送该第一切换请求信息中携带的第一帐号(即HUAWEI-01)。由于设备管理服务 器103中存储有帐号、电子设备的设备标识等(如表1所示)，因此，设备管理服务器103可以根据VoIP服务器104发来的第一帐号，查找到使用该第一帐号登录的各个电子设备，例如智能音箱102也使用了第一帐号登录了。当然，使用该第一帐号登录的电子设备可能有一个或多个，设备管理服务器103可以将所有使用第一帐号登录的电子设备的设备标识通过网络109发送给VoIP服务器104。在另一些情况下，设备管理服务器103也可以将所有使用第一帐号登录的电子设备中支持VoIP业务的电子设备的设备标识发送给VoIP服务器104。
VoIP服务器104接收到设备管理服务器103发来的设备标识符后，可通过设备标识查询在上述第一帐号下正在进行VoIP业务的源设备。例如，设备管理服务器103根据帐号HUAWEI-01查询到智能音箱102的设备标识，并将该设备标识发送给VoIP服务器。VoIP服务器104可以由此确定出执行VoIP业务的源设备为智能音箱102，也即用户需要将智能音箱102上正在执行的VoIP业务切换至手机101。
在另外一些实施例中，如果使用第一帐号登录的有两个或两个以上的电子设备都在执行VoIP业务，例如，除了智能音箱102外，平板电脑111上也正在执行VoIP业务。那么，VoIP服务器104可将这两个电子设备的设备标识均通过网络109发送给手机101。此时，如图5所示，手机101的触摸屏上可显示提示框501，在提示框501中有一个或多个选项，该选项列出了在第一帐号(例如HUAWEI-01)下正在进行VoIP业务的多个源设备的列表。这样，用户可以在提示框501中选择将哪一个电子设备上的VoIP业务切换到手机101中。例如，当手机101检测到用户选择了表示智能音箱102的选项后，手机101可将智能音箱102的标识发送给VoIP服务器104。这样，VoIP服务器104便可确定出用户需要切换的VoIP业务的源设备为智能音箱102。
步骤S407：VoIP服务器104将在智能音箱上正进行的VoIP通话切换到手机101上。
示例性地，首先，VoIP服务器104可以将手机101添加到智能音箱102与手机107之间的VoIP通话中。具体的，VoIP服务器104可以根据手机101在VoIP业务中的VoIP标识，将手机101添加到智能音箱102与手机107之间的VoIP业务中。此时，就在手机101、智能音箱102与手机107之间建立了VoIP业务的多方通话。
手机101的VoIP标识可以携带在手机101第一切换请求信息中。或者，VoIP服务器104中可以预先注册各个电子设备在VoIP业务中的VoIP标识。这样，在VoIP服务器104可以查询到手机101在VoIP业务中的VoIP标识。
在手机101、智能音箱102与手机107之间建立了VoIP业务的多方通话后，手机101可以通过网络109向VoIP服务器104发送成功加入VoIP业务的响应消息。
在接到上述响应消息后，VoIP服务器104中断智能音箱102的VoIP业务。中断后，此时只有手机101与手机107在进行VoIP通话。
在一些实施例中，当VoIP服务器104将手机101添加到智能音箱102与手机107之间的VoIP业务后，如果手机101成功接入了该VoIP业务，说明用户已经使用手机101接通了与手机107之间的VoIP语音通话。进而，手机101可向VoIP服务器104发送成功加入该VoIP业务的响应消息。接收到该响应消息后，VoIP服务器104可在手机101、智能音箱102与手机107组成的多方通话中将智能音箱102去除，即中断智能音箱102的VoIP业务，从而使得该VoIP业务从智能音箱102切换到手机101上继续执行。
可以看出，在手机101向VoIP服务器104发送成功加入VoIP业务的响应消息之前，智能音箱102和手机101上均接入了VoIP业务。当用户在手机101上接听了该VoIP语音通话后，手机101才会向VoIP服务器104发送上述响应消息，以触发VoIP服务器104中断智能音箱102的VoIP业务。这样一来，VoIP业务在手机101和智能音箱102之间切换时不会发生中断，且用户从智能音箱102切换到手机101上进行VoIP语音通话时可实现VoIP语音通话的无缝衔接，从而提高了多设备之间的语音切换效率和用户的使用体验。
在另一些实施例中，VoIP服务器104也可以根据手机101在VoIP业务中的VoIP标识(例如手机101的电话号码)，通过呼叫转移业务将智能音箱102的VoIP通话转移至手机101中，从而将智能音箱102上正在进行的VoIP通话切换至手机101中继续进行。
在上述实施例提供的技术方案中，VoIP业务的源设备为智能音箱102，VoIP业务的目标设备为手机101。手机101可以响应用户的特定操作识别出VoIP业务的切换需求。进而，手机101可向VoIP服务器104发送第一切换请求信息，使得VoIP服务器104将同一帐号下在智能音箱102上正在执行的VoIP业务无缝切换到手机101上。切换过程中不会发生VoIP业务中断的现象，用户也无需在多个设备之间反复操作，从而提高了多设备之间的语音切换效率和用户的使用体验。
在另一些应用场景中，如果用户希望将正在智能音箱102上进行的VoIP通话切换至手机101上，则用户可对智能音箱102输入一个的特定操作，以触发VoIP服务器104将智能音箱102上的VoIP通话切换至在该同一帐号下登录的其他电子设备(例如手机101)上。
示例性的，如图6所示，本实施例提供的一种语音切换方法包括：
步骤S601、手机101和智能音箱102均使用第一帐号登录到设备管理服务器103。
步骤S602：智能音箱102检测到用户108发起语音通话的输入操作。
步骤S603：响应于上述输入操作，智能音箱102通过VoIP服务器104建立与第三电子设备(例如图1所示的手机107)之间的VoIP通话。
其中，步骤S601-S603的具体实现方法可参见上述实施例中步骤S401-S402的相关描述，故此处不再赘述。
步骤S604、智能音箱102向VoIP服务器104发送第二切换请求信息，该第二切换请求信息用于请求VoIP服务器104将智能音箱102中正在进行的VoIP业务切换到手机101上继续进行。
其中，该第二切换请求信息中可以包括上述第一帐号。
在该应用场景下，用户希望将智能音箱102中正在进行的VoIP通话切换到手机101上继续执行。用户可以通过向源设备(即智能音箱102)上执行一输入操作，触发VoIP服务器104将上述智能音箱102中正在执行的VoIP通话切换到手机101上执行。
示例性的，上述输入操作可以为用户的语音输入。例如，当用户希望将智能音箱102中正在执行的VoIP通话切换到手机101上执行时，智能音箱102的语音助理系统可能处理未激活状态，那么用户可以先向智能音箱102语音输入唤醒词，例如“你好，小E”。当智能音箱102检测到该唤醒词时，智能音箱102的上述语音助理系统被启动，并采集用户进一步的语音输入，以便上述语音助理系统对该语音输入进行语音识别处理。
在一些实施例中，在上述语音助理系统被唤醒后，用户可以继续向智能音箱102进行语音输入。例如，用户的语音输入可以为：“将语音通话切换到我的手机”，即执行VoIP通话的目标设备切换为用户的手机101。智能音箱102对该语音输入进行语音识别后，智能音箱102可生成第二切换请求信息，并将该第二切换请求信息发送给VoIP服务器104，其中，该第二切换请求信息用于请求VoIP服务器104将正在进行的VoIP通话切换到手机101的第二切换请求信息。该第二切换请求信息中可以包括智能音箱102当前登录的第一帐号(例如HUAWEI-01)以及目标设备(即手机101)的设备标识。
在其他一些实施例中，上述语音输入也可以为：“切换语音通话”。智能音箱102对该语音输入进行语音识别后，可以确定出用户的操作意图为将智能音箱102中正在执行的VoIP通话切换到用户的其他电子设备中，但该语音输入中并没有明确指出将上述VoIP通话切换到用户的哪个电子设备继续执行。此时，智能音箱102生成的第二切换请求信息中可包括智能音箱102当前登录的第一帐号，但不包括目标设备(即手机101)的设备标识。
在另一些实施例中，可以在智能音箱102中预先设置将VoIP通话切换至用户的另一默认的电子设备例如手机101上继续执行。那么，当上述语音输入中没有指出目标设备时，智能音箱102可默认将用户的手机101作为切换后执行VoIP通话的目标设备。此时，智能音箱102生成的第二切换请求信息中还可以包括默认的目标设备(即手机101)的设备标识。
在另一些实施例中，智能音箱102采集到用户的语音输入后，也可以将该语音输入通过网络109发送给语音助理服务器105，由语音助理服务器105对该语音输入进行语音识别。进而，语音助理服务器105将语音识别结果可以反馈给智能音箱102，由智能音箱102根据语音识别结果生成上述第二切换请求信息，并通过网络109发送给VoIP服务器104。
在其他一些实施例中，智能音箱102还可以根据检测到的特定条件，自动通过网络109向VoIP服务器104发送上述第二切换请求信息，而不需要用户向智能音箱102输入一个语音输入。
示例性的，上述特定条件可以是WLAN网络中的Wi-Fi信号强度。手机101与智能音箱102均接入到了同一个路由器的Wi-Fi网络。当路由器检测到手机101在某一个时刻断开了Wi-Fi网络连接，或检测到的手机101的Wi-Fi信号低于一预设阈值时，路由器可自动向智能音箱102发送一条通知信息，该通知信息指示手机101已远离Wi-Fi网络。在这种情况下，智能音箱102可以自动通过网络109发送上述第二切换请求信息给VoIP服务器104，请求VoIP服务器104在智能音箱102中正在进行的VoIP通话切换至手机101，这样用户就可以方便地在手机101继续进行VoIP通话了。在该场景中，用户首先通过智能音箱102与手机107正在进行VoIP通话，然后，用户拿起手机远离智能音箱102，也同时远离了上述Wi-Fi网络。这个时候，将上述VoIP通话自动切换至用户的手机，以继续进行该VoIP通话，这样就提高了VoIP通话的效率，也提高了用户的体验。
示例性的，上述特定条件也可以是蓝牙信号强度。示例性地，手机101与智能音箱102之间可建立蓝牙连接，这样，智能音箱102可以根据检测到的手机101与智能音箱102之间蓝牙信号强度，确定是否自动向VoIP服务器104发送上述第二切换请求信息。例如，当智能音箱102检测到与手机101之间的蓝牙连接断开，或者，当智能音箱102检测到手机101的蓝牙信号强度小于一预设阈值时，智能音箱102可自动向VoIP服务器104发送上述第二切换请求信息。
需要说明的是，本领域技术人员可以根据实际应用场景或实际经验设置智能音箱102向VoIP服务器104发送第二切换请求信息的具体技术方案，本实施例对此不做任何限制。例如，智能音箱102可 以预先设置敲击智能音箱102一次的手势用于触发智能音箱102将正在进行的VoIP通话切换至手机，敲击智能音箱102两次的手势用于触发智能音箱102将上述VoIP通话切换至平板电脑111等。
步骤S605：VoIP服务器104接收到智能音箱102发送的上述第二切换请求信息。
步骤S606：响应于接收到上述第二切换请求信息，VoIP服务器104确定与上述第一帐号对应的VoIP业务的源设备为智能音箱102。
步骤S607：VoIP服务器104将上述VoIP通话切换至手机101上进行。
首先，VoIP服务器104可以从使用第一帐号登录的多个电子设备中确定执行VoIP通话的目标设备为手机101。VoIP服务器104接收到智能音箱102发来的第二切换请求信息后，可将第二切换请求信息中携带的第一帐号(即HUAWEI-01)发送给设备管理服务器103。进而，设备管理服务器103可查询到当前使用第一帐号的所有电子设备。例如，除了智能音箱102外，还有手机101和平板电脑111也使用了第一登录。那么，设备管理服务器103可将手机101和平板电脑111的设备标识通过网络109发送给VoIP服务器104，由VoIP服务器104在这些电子设备中确定后续代替智能音箱102继续执行VoIP通话的目标设备。
示例性的，如果上述第二切换请求信息中携带有目标设备的设备标识(例如手机101的设备标识)，则VoIP服务器104可在设备管理服务器103发来的设备标识中查询是否包含手机101的设备标识。若包含手机101的设备标识，则VoIP服务器104可确定执行VoIP通话的目标设备为手机101。
或者，如果上述第二切换请求信息中没有携带目标设备的标识，则VoIP服务器104可以从设备管理服务器103发来的设备标识中选择一个作为后续执行VoIP通话的目标设备的设备标识。
又或者，如果上述第二切换请求信息中没有携带目标设备的设备标识，VoIP服务器104可以将设备管理服务器103发来的多个电子设备的设备标识通过网络109发送给智能音箱102。如图7所示，智能音箱102可显示提示框701，在提示框701中列出在第一帐号下能够继续执行VoIP通话的目标设备的选项。这样，用户可以在提示框701中手动选择将智能音箱102上的VoIP通话切换到哪一个电子设备上执行。例如，当检测到用户选中了提示框901中的手机101后，智能音箱102可将手机101的设备标识发送给VoIP服务器104。这样，VoIP服务器104便可确定出后续继续执行VoIP通话的目标设备为手机101。
VoIP服务器104中可以预先注册各个电子设备在VoIP业务中的VoIP标识。该VoIP标识可以是执行VoIP业务时使用的电话号码或IP地址等。那么，VoIP服务器104将手机101确定为后续代替智能音箱102继续执行VoIP通话的目标设备后，可以查询到手机101的VoIP标识，例如手机101的电话号码为123456。进而，VoIP服务器104可按照该电话号码将手机101添加到智能音箱102与手机107之间的VoIP通话中。此时，VoIP服务器104在手机101、智能音箱102与手机107之间建立了VoIP多方通话。然后，VoIP服务器104中断智能音箱102的VoIP业务。中断后，此时只有手机101与手机107在进行VoIP通话，也即VoIP通话切换到手机101上。此时，手机101与手机107进行VoIP通话。
在本实施例提供的语音切换方法中，VoIP业务的源设备为智能音箱102，VoIP业务的目标设备为手机101。智能音箱102可以响应用户执行的触发操作识别出VoIP业务的切换需求。进而，智能音箱102可向VoIP服务器104发送第二切换请求信息，使得VoIP服务器104将同一帐号下在智能音箱102 上执行的VoIP业务无缝切换到手机101上继续执行。切换过程中不会发生VoIP业务中断的现象，用户也无需在多个设备之间反复操作，从而提高了多设备之间的语音切换效率和用户的使用体验。
在另一些应用场景中，用户在手机101和智能音箱102上使用同一帐号登录设备管理服务器103后，与上述实施例中所涉及的应用场景不同的是，用户可通过手机101与其他电子设备(例如手机107)进行VoIP业务。后续，如果用户希望将该VoIP业务从手机101切换至智能音箱102上，用户可在智能音箱102上或者手机101上做预设的输入操作，以触发VoIP服务器104将手机101上正在进行的VoIP通话自动切换至智能音箱102上；或者，手机101或智能音箱102检测到一特定条件，而自动进行切换VoIP通话到智能音箱102的流程。在该应用场景下的具体技术方案与上述实施例中涉及的技术方案类似，在此不再赘述。需要详细说明的是，在本应用场景中，手机101或智能音箱102检测到一特定条件可以是以下几种。
示例性地，该特定条件可以是手机101当前的状态信息。手机101可以通过一个或多个传感器180采集各种环境信息、手机姿态信息等。例如，当手机通过加速度传感器180E检测手机当前静止了超过一预设时间段了，而且手机已经接入了与智能音箱102同一个Wi-Fi网络，则手机101根据检测到的上述状态信息，可以自动向VoIP服务器104发送切换请求信息，以便VoIP服务器104将手机101上正在进行的VoIP通话自动切换至智能音箱102上。
示例性地，该特定条件也可以是手机101与智能音箱102建立的蓝牙连接。例如，用户最初是在手机101上与手机107进行VoIP通话，当用户到家时，手机101与智能音箱102可以自动建立蓝牙连接。在这两个设备建立了蓝牙连接后，手机101或者智能音箱102可以自动向VoIP服务器104发送切换请求信息，以便VoIP服务器104将手机101上正在进行的VoIP通话自动切换至智能音箱102上。
在其他一些应用场景中，用户在手机101和智能音箱102上使用同一帐号登录设备管理服务器103后，用户可使用智能音箱102执行音频/视频播放业务。如果用户希望将音频播放业务从智能音箱102切换至手机101上，用户可在手机101或智能音箱102上执行预设的特定操作，以触发内容服务器106将智能音箱102上的音频播放业务切换至手机101上。
示例性的，如图8所示，本实施例提供的一种语音切换方法，包括：
步骤S801：手机101和智能音箱102均使用同一帐号(例如第一帐号)登录设备管理服务器103。
其中，手机101和智能音箱102使用第一帐号登录设备管理服务器103的具体方法可参见上述相关实施例，故此处不再赘述。
步骤S802：智能音箱102接收用户的语音输入，该语音输入用于指示智能音箱102播放音频B；
步骤S803：响应于该语音输入，智能音箱102确定音频B的播放指令。
步骤S804：根据上述播放指令，智能音箱102从内容服务器106中获取播放信息，并播放音频B。
当用户希望使用智能音箱102播放某一音频B(例如歌曲Silence)时，用户可向智能音箱102说“我要收听Silence这首歌”。进而，智能音箱102根据其配置的语音助理系统将该语音输入识别为语音指令，该语音指令用于指示播放歌曲Silence；然后，智能音箱102将播放音频的请求信息通过网络109发送给内容服务器106，内容服务器106在接收到上述请求信息后，像智能音箱102提供歌曲Silence的播放业务。进而，智能音箱102从内容服务器106中获取的播放信息中播放歌曲Silence，可以通过智能音箱102的一个或多个扬声器阵列370A来播放歌曲。
在另一些实施例中，采集到用户的上述语音输入后，智能音箱102可将该语音输入携带在识别请求中通过网络109发送给语音助理服务器105。语音助理服务器105可使用语音识别算法对上述语音输入进行语音识别，得到歌曲Silence的播放指令。语音助理服务器105将识别出的播放指令发送给内容服务器106，由内容服务器106向智能音箱102提供歌曲Silence的播放业务。
在另一些实施例中，用户除了通过输入语音的方式触发智能音箱102执行音频播放业务外，还可以通过其他预设的方式触发智能音箱102得到某一音频的播放指令，本申请实施例对此不做任何限制。例如，当检测到用户敲击智能音箱102后，说明用户希望继续播放最近一次收听的节目(例如节目C)，则智能音箱102可生成节目C的播放指令发送给内容服务器106。又例如，如果智能音箱中设置有触摸屏，则用户可以在触摸屏中选择需要播放的音频，进而触发智能音箱102生成该音频的播放指令并发送给内容服务器106。
内容服务器106可用于维护音乐、节目等音频内容的资源信息。语音助理服务器105将识别出的音频播放指令发送给内容服务器106后，内容服务器106可查找音频B的资源信息。其中，该资源信息可以是音频B的音频资源，也可以是音频B的播放地址或下载地址等。内容服务器106将音频B的资源信息发送给智能音箱102，以使得智能音箱102按照该资源信息播放音频B。以音频B的资源信息为音频B的播放地址举例，内容服务器106可将音频B的播放地址发送给智能音箱102。这样，智能音箱102根据该播放地址可以获取到音频B的音频资源，进而执行音频B的音频播放业务。
可以理解的是，内容服务器106中可以存储音频资源、请求播放的设备的设备标识等信息，以便后续对进一步处理。
步骤S805：手机101向内容服务器106发送播放切换请求。
步骤S806：响应于上述播放切换请求，内容服务器106确定播放音频B的源设备为智能音箱102。
步骤S807：内容服务器106将上述音频播放业务切换至手机101上继续进行。
在一些实施例中，上述播放切换请求中可以包括第一帐号，手机101和智能音箱102均使用该第一帐号登录到了设备管理服务器103中。在另一些实施例中，上述播放切换请求也可以包括手机101的设备标识和/或智能音箱102的设备标识。
当用户希望将智能音箱102中正在播放的音频B切换到手机101上继续播放时，用户可以在手机101上输入一预设的特定操作。响应于该特定操作，手机101可向内容服务器106发送播放切换请求，由内容服务器106确定正在播放音频B的源设备即智能音箱102。
内容服务器106可向设备管理服务器103发送第一帐号，由设备管理服务器103查询当前登录该第一帐号的电子设备有哪些。进而，内容服务器106可将正在播放音频B的电子设备(例如上述智能音箱102)确定为播放音频内容B的源设备。
当然，如果第一播放切换请求中携带有用户指定的源设备(例如智能音箱102)，且智能音箱102正在帐号A下播放音频内容B(即执行音频播放业务)，则内容服务器106可确定在第一帐号下播放音频B的源设备为智能音箱102。
容服务器106确定出播放音频B的源设备为智能音箱102后，为了使得后续将音频B切换到智能音箱102时，手机101能够从当前的播放位置继续播放该音频B，内容服务器106可查询音频B在智能音箱102上的播放进度。
内容服务器106向手机101发送音频B的资源信息和播放进度。手机101按照音频B的资源信息和播放进度继续播放音频B。
内容服务器106得到音频内容B在智能音箱102中的播放进度后，可以将音频B的播放进度和资源信息发送给手机101。这样，手机101可以按照音频B的资源信息获取到音频B，并且，手机101可以按照音频B的播放进度从智能音箱102当前播放的位置继续播放音频B，实现音频播放业务在智能音箱102和手机101之间的无缝切换。在手机101接收到该视频B后，内容服务器可以自动中断在智能音箱102上播放音频B的音频播放业务。
在另一些实施例中，手机101可以通过网络109向内容服务器106发送音频B的播放事件；响应于上述播放事件，内容服务器106中断在智能音箱102上播放音频B的音频播放业务。
当手机101开始播放音频B后，原本在智能音箱102上播放的音频B可能并未自动中断。那么，当手机101开始播放音频B后，手机101可自动向内容服务器106发送音频B的播放事件。这样，内容服务器106接收到该播放事件后便可停止智能音箱102的音频播放业务。例如，响应于手机101上报的播放事件，内容服务器106可向智能音箱102发送停止播放指令，以使得智能音箱102响应该停止播放指令停止在智能音箱102上播放音频B。
在另一些实施例中，可以设置当智能音箱102和手机101同时播放一段时间的音频B后，再停止在智能音箱102上播放音频B。例如，可以在手机101播放了3s的音频B后，再向内容服务器106发送音频B的播放事件。那么，在手机101刚开始播放音频内容B的3秒内，智能音箱102也在同时播放音频B。这样，即使音频播放业务切换至手机101时因传输时延导致一些音频遗漏，用户也可结合智能音箱102上播放的音频B得到完整的音频内容，从而提高语音切换效率和使用体验。
在上述实施例提供的语音切换方法中，音频播放业务的源设备为智能音箱102，音频播放业务的目标设备为手机101。手机101可以响应用户执行的触发操作识别出音频播放业务的切换需求。进而，手机101可向内容服务器106发送第一播放切换请求，内容服务器106将同一帐号下在智能音箱102上执行的音频播放业务无缝切换到手机101上继续执行。切换过程中不会发生音频播放业务中断的现象，用户也无需在多个设备之间反复操作，从而提高了多设备之间的语音切换效率和用户的使用体验。
在另一些应用场景中，用户在手机101和智能音箱102上使用同一帐号登录设备管理服务器103后，用户可使用智能音箱102执行音频播放业务。如果用户希望将该音频播放业务从智能音箱102切换至手机101上，则用户也可在智能音箱102上做预设的一特定操作，以触发内容服务器106将智能音箱102上的音频播放业务切换至手机101上。该特定操作可以是用户对智能音箱102的语音输入，例如用户对智能音箱102说“把歌曲Silence切换到手机上播放”。智能音箱102对该语音输入的处理方式可以参加上述实施例中的相关描述，在此不再赘述。
在另一些应用场景中，当用户使用手机101执行音频播放业务时，如果后续用户希望将该音频播放业务从手机101切换至智能音箱102上，则用户可在智能音箱102/或手机101上做一个预设的输入操作，以触发内容服务器106将手机101上的音频播放业务切换至智能音箱102上。具体技术方案请参见上述实施例中的相关描述，在此不再赘述。
