Description

通话控制方法、电子设备及存储介质
本申请要求于2022年10月31日提交国家知识产权局、申请号为202211350598.8、申请名称为“通话控制方法、电子设备及存储介质”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
本申请涉及电子技术领域，尤其涉及一种通话控制方法、电子设备及存储介质。
背景技术
目前，大部分手机是采用设置在手机顶部的听筒实现手机的语音通信发声的。通常，手机需要在听筒的位置对应设置出音孔以释放听筒发声时的能量，出音孔一般开设在手机的前面板上。随着大屏以及全面屏手机的发展，一些全面屏手机的出音孔设计为长缝形态，位于手机中框和前面板的连接处，同时为了确保外放出声面积够大，具有良好出音效果，在一些全面屏手机上还会在中框顶部增加开孔作为出音孔。
然而，在用户手持手机贴耳听音(例如语音通话场景)的过程中，通过听筒输出的语音不只是从侧缝处的出音孔发出，还有很大一部分能量从顶部出音孔发出，因此由出音孔出来的声音不光能够被该用户听到，在安静环境下还能够被其他用户听到，存在漏音现象，容易泄露用户隐私。
发明内容
本申请提供一种通话控制方法及电子设备，解决了在用户手持手机贴耳听音的场景中通过听筒播放语音时存在漏音现象的问题。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种通话控制方法，应用于电子设备，该电子设备包括听筒、屏幕和屏幕发声装置，该屏幕发声装置用于驱动屏幕进行屏幕发声，该通话控制方法包括：
当所述电子设备的系统设置的通话音量为第一音量时，所述电子设备接收第一来电；
所述电子设备接收用户的第一操作，并响应于所述第一操作，接通所述第一来电，所述电子设备的所述听筒和所述屏幕发声装置以第一比例和所述第一音量发出第一声音；
在所述第一来电的通话过程中，所述电子设备接收用户的第二操作，响应于所述第二操作，所述听筒和所述屏幕发声装置以第二比例和第二音量发出第二声音，所述第二音量大于第一音量；
所述电子设备接收用户的第三操作，并响应于所述第三操作，结束所述第一来电；
当所述电子设备的系统设置的通话音量为所述第二音量时，所述电子设备接收第二来电；
所述电子设备接收用户的第四操作，并响应于所述第四操作，接通所述第二来电，所述电子设备的所述听筒和所述屏幕发声装置以第三比例和第三音量发出第三声音，其中，所述第三音量大于所述第一音量，所述第三音量小于所述第二音量；
其中，所述第一比例和所述第二比例不同，所述第三比例和所述第二比例不同。
通过本申请实施例提供的方案，在来电接听时，当系统通话音量相对较低时，该系统通话音量保持即可，且进入隐私通话模式，不仅可减少漏音，而且可以满足用户的使用习惯；当系统通话音量较高时，自动减小音量，且进入隐私通话模式，由此可减少漏音，因此本申请方案可以基于接听前的系统通话音量将接听音量自动调节到合适的音量，满足用户通话需求，提升用户通话体验。
需要说明的是，这里以来电场景为例进行说明，可以理解，在实际实现时，本申请实施例提供的通话控制方法同样可以应用于去电场景。
这里以举例方式简单描述本申请实施例提供的通话控制方法。
首先，电子设备接收到来电通知并显示来电通知界面，该来电通知界面中显示有提示信息“智慧隐私通话模式”，表明智慧隐私通话功能已默认开启，一旦来电接通后即可采用“智慧隐私通话模式”输出语音。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
目前，大部分手机是采用设置在手机顶部的听筒实现手机的语音通信发声的。通常，手机需要在听筒的位置对应设置出音孔以释放听筒发声时的能量，出音孔一般开设在手机的前面板上。但是，随着手机的不断发展，为了向用户提供更好的屏幕观看体验，手机屏幕的屏占比越来越高。设置在前面板上的出音孔由于占用了手机的前面板部分区域，会增加手机边框的宽度，所以会影响手机进一步提高屏幕的屏占比。
因此，随着大屏以及全面屏手机的发展，为了减小用于语音通信中通话发声的听筒(也称为受话器)的出音孔在手机的前面板上占用的面积，以进一步提高屏幕的屏占比，一些全面屏手机的听筒出音孔设计为长缝形态，位于手机中框和前面板的连接处，同时为了确保外放出声面积够大，具有良好出音效果，在一些全面屏手机上还会增加中框顶部开孔作为出音孔。
例如，图1示出了一种手机的结构示意图。如图1所示，该手机可以包括用于设置屏幕的前面板(通常包括屏幕和边框)、用于支撑内部电路的后面板以及中框，通过前面板、后面板以及中框能够围合成壳体结构。如图1中的(a)所示，在该壳体结构内，位于顶部的位置(即手机顶部位置)设置有听筒101(即用于语音通信中通话发声的扬声器，也称为受话器)。对应于该听筒101，手机设置有两处出音孔(如，出音孔102和出音孔103)，听筒101的声音可以从出音孔出音。结合图1中的(b)所示，图1中的(b)为手机结构的剖视图，其中出音孔102位于该手机前面板和中框的连接处(即侧缝处)。出音孔103则位于该手机的中框上距离上述听筒101较近的位置(即手机的中框顶部位置)。
但是，此种方式设置的出音孔，在用户正常使用手机进行语音通信时，用户的耳廓无法完全覆盖包裹出音孔，所以当扬声器的声音能量由开设在手机中框顶部的出音孔出来时，会有漏音现象。图1中的(c)示出了用户通过手机进行语音通信的场景示意图。如图1中的(c)所示，用户手持手机通过听筒进行语音通信的过程中，手机听筒靠近用户的耳朵(或者说耳廓)，由于手机听筒的出音孔(位于手机侧缝处的出音孔102和中框顶部的出音孔103)无法被用户的耳朵完全包裹覆盖，所以由出音孔出来的声音不光能够被该用户听到，在安静环境下还能够被其他用户听到。
为解决上述问题，本申请实施例提供一种通话控制方法，该方法可以应用于具有语音通信功能的电子设备，例如该通话控制方法可以应用于用户通过上述电子设备进行贴耳听音的场景中，如用户通过听筒进行语音通话，或者通过听筒收听即时通讯应用中的语音消息等。其中，上述电子设备可以包括显示屏(也称为屏幕)、屏幕发声装置(即能够通过屏幕振动发声的装置)，听筒(即上述的用于语音通信中通话发声的扬声器，也称为受话器)以及对应该听筒开设的出音孔。
例如，图2示出了本申请实施例提供的一种电子设备的结构示意图。如图2中的(a) 和图2中的(b)所示，除了设置有图1所示的听筒101、出音孔102和出音孔103之外，电子设备还设置有与屏幕连接的屏幕发声装置104。例如，屏幕发声装置104是与屏幕连接的振动源(也称为激励器)。激励器引起屏幕振动，实现通过屏幕发声。其中，屏幕发声装置104设置于电子设备的壳体结构内。
需要说明的是，在本申请实施例中，电子设备的语音输出模式(也称为听音模式)可以包括隐私通话模式(privacy mode，PVM)，正常模式，以及扬声器模式。其中，隐私通话模式也可以称为智慧隐私模式或者智慧隐私通话模式或者PVM模式。正常模式也可以称为常规(normal)模式。
在一些实施例中，在电子设备开启隐私通话模式后，电子设备可以结合屏幕发声方式和听筒发声方式来输出语音。示例性地，屏幕发声方式对应的语音输出强度(例如70％)大于或等于听筒发声方式对应的语音输出强度(例如30％)。即，手机可以采用屏幕发声为主、听筒发声为辅的方式同时播放语音。
在另一些实施例中，在电子设备开启隐私通话模式后，电子设备还可以仅通过屏幕发声方式来输出语音。可以理解，此时听筒不发声。
需要说明的是，在实际实现时，在隐私通话模式下，具体是通过屏幕发声方式输出语音，还是通过屏幕发声为主、听筒发声为辅的方式输出语音，可以根据实际使用需求确定，本申请实施例不作限定。
在一些实施例中，在电子设备开启正常模式后，电子设备可以结合采用听筒发声方式和屏幕发声方式来输出语音。示例性地，听筒发声方式对应的语音输出强度(例如70％)大于屏幕发声方式对应的语音输出强度(例如30％)。手机可以采用听筒发声为主、屏幕发声为辅的方式同时播放语音。
在另一些实施例中，在电子设备开启正常模式后，电子设备还可以仅通过听筒发声方式来输出语音。可以理解，此时屏幕不发声。
需要说明的是，在实际实现时，在正常模式下，具体是通过听筒发声方式输出语音，还是通过听筒发声为主、屏幕发声为辅的方式输出语音，可以根据实际使用需求确定，本申请实施例不作限定。
在一些实施例中，当从隐私通话模式切换到正常模式时，还可以在隐私通话模式对应的音量基础上，增大整体发声音量(或称为响度或强度)，以提升语音播放效果。也就是说，在正常模式下通过听筒发声和屏幕发声时的整体发声响度，大于在隐私通话模式下通过听筒发声和屏幕发声时的整体发声响度。
相比于听筒发声方式，屏幕发声方式能有效防止语音通话时漏音，因此当用户处于安静环境中接打电话时，用户通常希望减少漏音，此时可以采用隐私通话模式，能够保证通话清晰的同时，减少漏音，从而起到保护用户隐私的效果。
在一些实施例中，在电子设备开启扬声器模式后，电子设备通过扬声器(也称为喇叭)输出语音。可以理解，此时听筒和屏幕均不发声。
需要说明的是，响应于用户对电子设备的操作，电子设备可以控制语音输出方式在隐私通话模式、正常模式以及扬声器模式之间切换。具体触发切换的条件以及切换过程，将在下文中进行详细描述。
在一些实施例中，电子设备可以预先设置隐私通话模式处于默认开启状态。这样，当 电子设备拨通电话或者接听来电后，自动启用隐私通话模式，以免通话漏音，无需用户操作，提升了用户使用体验。
在一些实施例中，在拨通电话或者接听来电时，可以根据系统通话音量(具体为音量等级)，将本次接听后的输出音量自动调节到合适的音量等级，以保障通话隐私及通话清晰度。
在一些实施例中，在通话过程中，在当前音量等级为可调音量等级时，可以根据环境声大小自动切换模式，即在安静环境中自动切换到隐私通话模式并自动减小音量，由此可减少漏音；在嘈杂环境中自动切换到正常模式并自动增大音量，由此可保证通话清晰度。这种方式可以称为自动调节模式。
在一些实施例中，在隐私通话模式未开启的情况下，在来电通知界面中可以提示用户如何开启隐私通话模式的操作方式。例如，在来电通知时，通过双击音量下键，可开启或进入隐私通话模式。或者，在来电通知时，如果用户单击音量下键，那么来电通知的铃声静音；此时如果用户再次单击音量下键，那么电子设备在来电通知界面上可以显示音量条，这样用户可以在接收到来电通知时即可提前调节好接听音量大小，这种方式不同于目前只能通过在来电接通后才能调节接听音量大小的方式。这种方式可以称为手动调节模式。
在一些实施例中，在通话过程中，电子设备可以根据用户调节音量条的操作，退出或进入隐私通话模式。例如，电子设备可以响应于用户调高音量条的操作，退出隐私通话模式；电子设备可以响应于用户调低音量条的操作，再次切换到(或者进入)隐私通话模式。可以理解，这种方式也属于手动调节模式。
例如，当接收到用户降低音量或提高音量的操作时，若判断调节后的音量等级小于或等于预设音量等级(例如音量8级)，则启用隐私通话模式，例如可以通过屏幕和听筒同时发声并控制这两种发声方式以不同的音量强度进行发声(如屏幕发声的强度大于或等于听筒发声的强度)，以避免漏音，保护用户通话隐私，提升用户通话体验。若判断调节后的音量等级大于预设音量等级，则启用正常模式，例如可以通过屏幕和听筒同时发声并控制这两种发声方式以不同的音量强度进行发声(如听筒发声的强度大于屏幕发声的强度)，以保证良好的出音效果，提升用户通话体验。
本申请实施例提供的通话控制方法，可以在来电接听时根据系统通话音量将接听音量自动调节到合适的音量并启用隐私通话模式，并且在通话过程中，可以实现根据环境声大小自动切换模式，即在安静环境中自动切换到隐私通话模式并自动减小音量，由此可减少漏音；在嘈杂环境中自动切换到正常模式并自动增大音量，由此可保证通话清晰度；并且在通话过程中，还可以根据用户实际需要，响应于用户手动触发操作，在隐私通话模式与正常模式之间进行切换，因此本申可以满足各种场景下用户通话的需求。

本申请实施例提供的通话控制方法的执行主体可以为上述的电子设备，也可以为该电子设备中能够实现该通话控制方法的功能模块和/或功能实体，并且本申请方案能够通过硬件和/或软件的方式实现，具体的可以根据实际使用需求确定，本申请实施例不作限定。下面以电子设备为例，结合附图对本申请实施例提供的通话控制方法进行示例性的说明。
下面将结合附图，通过下述多个示例性实施例对本申请实施例进行举例说明。以下实施例中的方法均可以在具有上述硬件结构和软件架构的电子设备中实现。电子设备的硬件结构图可以如图3所示，电子设备的软件结构框图可以如图4所示，但本申请实施例并不限于此。为了便于说明，本申请实施例中均以电子设备为如图3所示的手机为例。
本申请实施例提供一种通话控制方法，在来电接听时根据系统设置的通话音量(简称为系统通话音量，具体可以为音量等级)将接听音量自动调节到合适的音量等级并启用隐私通话模式，并且在通话过程中，可以实现根据环境声大小自动切换模式，即在安静环境中自动切换到隐私通话模式并自动减小音量，由此可减少漏音；在嘈杂环境中自动切换到正常模式并自动增大音量，由此可保证通话清晰度；并且在通话过程中，还可以根据用户实际需要，响应于用户手动触发操作，在隐私通话模式与正常模式之间进行切换，因此本申请方案可以满足各种场景下用户通话的需求。
本申请实施例提供的音频控制方法可以应用于语音通话场景。例如，语音通话场景可以是接到电话的来电场景，或者是来电接听后的通话场景，也可以是拨打电话的去电场景，或者是去电被接听后的通话场景，当然还可以是其他任意可能的语音通话场景，本申请实施例不作限定。为了便于说明，下文中将上述各种语音通话场景采用的界面统称为语音通话界面或者通话界面。
在本申请实施例中，电子设备默认已开启智慧隐私通话功能。在智慧隐私通话功能开启之后，隐私通话模式可以在语音通话的场景中直接启用，或者在语音通话的场景中当电子设备的音量值低于或等于预设音量等级(例如音量8级)时启用，具体可以根据实际使用需求确定，本申请实施例不作限定。
如上所述，隐私通话模式可以结合采用屏幕发声方式和听筒发声方式来输出语音。可选地，屏幕发声方式对应的语音输出强度大于或等于听筒发声方式对应的语音输出强度。或者，隐私通话模式可以仅通过屏幕发声方式来输出语音。相比于听筒发声方式，屏幕发声方式能有效防止语音通话时漏音，因此当用户处于安静环境中接打电话时，用户通常希望减少漏音，此时可以采用隐私通话模式，能够保证通话清晰的同时，减少漏音，从而起到保护用户隐私的效果。
在一些实施例中，当电子设备接到电话时，可以默认启用智慧隐私通话功能对应的隐私通话模式，并在来电通知界面中显示已开启智慧隐私通话功能相关的提示信息。可选地，该提示信息可以为文字，也可以为图标，也可以是文字与图标的组合。
在一些实施例中，在开启智慧隐私通话功能之后，在每次使用听筒接打时可以在语音通话界面在气泡框内显示智慧隐私通话功能的介绍说明(例如：保证通话清晰的同时，减少漏音、保护隐私)；还可以在特定区域(即屏幕发声区域)中显示诸如“智慧隐私通话已开启”和/或“靠近此区域，听得更清晰”等操作方式，通过这些提示信息介绍智慧隐私通话功能并引导用户使用智慧隐私通话功能。
示例性地，以来电场景为例，图5示出了来电通知界面的示意图，如图5中的(a)所 示，在来电通知界面40中显示有以下提示信息：“智慧隐私通话已开启”41，“保证通话清晰的同时，减少漏音、保护隐私”42(位于气泡框中)。如图5中的(b)所示，在来电通知界面40中显示有以下提示信息：“靠近此区域，听得更清晰”43以及“保证通话清晰的同时，减少漏音、保护隐私”42。这些提示信息均用于提示已启用隐私通话模式。其中，在来电通知界面40中可以交替显示(即轮播)“智慧隐私通话已开启”41和“靠近此区域，听得更清晰”43。这样可以让用户更快地获知智慧隐私通话功能并学习使用该功能，提升人机交互体验。
需要说明的是，这里的提示信息均为示例性地说明，提示信息的具体内容、显示位置、显示数量、显示尺寸、显示样式等可以根据实际使用需求确定，本申请实施例不作限定。
可选地，上述提示信息可以在开启智慧隐私通话功能之后的前N次通话场景(例如N为3)的语音通话界面中显示，以引导用户使用该智慧隐私通话功能，并在后续通话场景中取消显示。例如，在语音通话界面中可以取消显示诸如“保证通话清晰的同时，减少漏音、保护隐私”42等对智慧隐私通话功能的介绍说明。
在一些实施例中，当用户点击语音通话界面中的任意位置(包括接听键)时，在语音通话界面中取消显示对智慧隐私通话功能的介绍说明信息，例如“保证通话清晰的同时，减少漏音、保护隐私”42对应的气泡框消失。
在一些实施例中，在语音通话界面中，“智慧隐私通话已开启”可以为常驻提示。也就是说，当用户点击语音通话界面中的任意位置(包括接听键)时，“智慧隐私通话已开启”提示信息可以保持显示。
示例性地，以来电接听后的通话场景为例，图6示出了来电通知界面以及接听后的语音通话界面的示意图，如图6中的(a)所示，用户点击来电通知界面40中的接听键44，以接听电话。如图6中的(b)所示，响应于用户对接听键44的操作，来电通知界面40切换显示为语音通话界面45。在语音通话界面45中显示有以下提示信息：“智慧隐私通话已开启”41以及标识隐私通话的图标46。在图6中的(b)中，图6中的(a)所示的“保证通话清晰的同时，减少漏音、保护隐私”对应的气泡框消失。
在一些实施例中，当智慧隐私通话功能开启时，当用户下拉菜单栏时，菜单栏中显示有用于指示正在进行语音通话的通知卡片以及用于指示智慧隐私通话功能已开启的通知卡片。
示例性地，图7示出了菜单栏显示的关于智慧隐私通话功能的通知卡片的示意图，如图7中的(a)所示，用户在语音通话界面46上沿箭头方向向下滑动手指，以下拉菜单栏。如图7中的(b)所示，显示菜单栏(也称为通知界面或通知中心)，该菜单栏中显示有通知卡片47和通知卡片48，通知卡片47用于指示正在进行语音通话，通知卡片48用于指示智慧隐私通话功能已开启。
通过这些通知卡片，便于用户更好地获知智慧隐私通话功能的应用场景以及应用效果，提升用户使用体验。
在一些实施例中，本申请实施例提供的通话控制方法还适用于基于IP的语音电话(voice over Internet protocol，VoIP)。示例性地，图8示出了VoIP电话的通话场景的界面示意图，如图8所示，在VoIP通话界面50中显示有“智慧隐私通话已开启”51，以及标识隐私通话的图标52，用于提示当前通话场景采用隐私通话模式来实现语音输出。
以上说明了开启隐私通话模式的可能方式以及开启后的语音通话界面的显示效果，下面结合界面详细描述隐私通话模式在实际使用时的可能实现方式。
需要说明的是，以上实施例中是以来电场景以及来电接听后的通话场景为例进行示例性说明的，可以理解，在实际实现时，本申请实施例提供的通话控制方法也适用于去电场景以及去电接听后的通话场景，具体智慧隐私通话功能相关的描述可以参见上述来电场景以及来电接听后的通话场景中对智慧隐私通话功能相关的详细描述，此处不再赘述。
还需要说明的是，本申请实施例提供的通话控制方法还适用于播放语音消息的场景，例如一些社交应用支持接收或发送语音消息，这些语音消息在播放时也可以应用本申请实施例提供的智慧隐私通话功能，避免语音消息播放时漏音。
再需要说明的是，本申请实施例提供的通话控制方法还适用于播放录音的场景，例如在播放录音时也可以应用本申请实施例提供的智慧隐私通话功能，避免录音播放时漏音。
还需要说明的是，由于视频通话场景不存在贴耳听音的需求，因此，在视频通话场景下可以不开启智慧隐私通话功能。
可以理解，本申请实施例提供的通话控制方法可以适用于用户需要通过电子设备进行贴耳听音的各种场景，本申请实施例对此不作限定。
下面先结合附图示例性地描述本申请实施例中隐私通话模式所涉及的音量等级划分方式、各等级对应的音量条形式以及模式对应关系。
在一些实施例中，电子设备可以将不同音量划分为10个等级，包括1级至10级，其中从1级至10级对应的音量值逐级增大。其中，音量值可以采用分贝(dB)表示。音量等级的划分数量，以及每个等级对应的音量值或音量范围，具体可以根据实际使用需求确定，本申请实施例不作限定。
在本申请实施例中，本申请可以根据实际情况设置音量等级对应的模式。图9示出了音量等级的划分以及各个音量等级与音量值的映射关系的示意图。示例性地，如图9所示，音量等级可以被划分为1级到10级。可选地，音量等级范围[1级，8级]对应隐私通话模式，音量等级范围[9级，10级]对应正常模式。即，若音量等级在[1级，8级]音量等级范围内，则在通话时采用隐私通话模式输出语音；若音量等级在[9级，10级]音量范围内，则在通话时采用正常模式输出语音。示例性地，1级到10级分别对应的音量值为：16dB，13dB，10dB，7dB，4dB，2dB，0dB，-2dB，-5.8dB，-8.8dB。其中，0dB可以理解为基准音量，16dB，13dB，10dB，7dB，4dB以及2dB可以分别理解为基于0dB的减小量，-2dB，-5.8dB以及-8.8dB可以分别理解为基于0dB的增大量。当然，各个音量等级还可以对应其他音量值。
需要说明的是，这里各个音量等级与音量值的映射关系为示例性地说明，可以理解，在实际实现时，各个音量等级对应的音量值可以根据实际使用需求设置，本申请实施例不作限定。
在本申请实施例中，不管电子设备是处于隐私通话模式还是处于正常模式，均可以采用听筒和屏幕发声装置同时发声。
在本申请实施例中，屏幕发声装置负责输出高频声音，听筒负责输出中低频声音。
在一些实施例中，在不同的模式下，听筒和屏幕发声装置分别可以采用不同的发声强度比例发声。
示例性地，在电子设备开启隐私通话模式后，电子设备可以采用屏幕发声为主、听筒发声为辅的方式同时播放语音；其中，屏幕发声方式对应的语音输出强度(例如70％)大于或等于听筒发声方式对应的语音输出强度(例如30％)。
再示例性地，在电子设备处于正常模式时，电子设备可以采用听筒发声为主、屏幕发声为辅的方式同时播放语音；其中，听筒发声方式对应的语音输出强度(例如70％)大于屏幕发声方式对应的语音输出强度(例如30％)。
在一些实施例中，对于同一模式下的不同音量等级，听筒和屏幕发声装置分别可以采用不同的发声强度比例发声。例如，在[1级，8级]范围内，听筒和屏幕发声装置的发声强度比例可以设置为不同。
可以理解，在实际实现时，对于同一模式下的不同音量等级，听筒和屏幕发声装置的发声强度比例也可以设置为相同。具体可以根据实际使用需求确定，本申请实施例不做限定。为了便于说明，对于同一模式下的不同音量等级，下面以相同的发声强度比例进行示例性描述。例如当系统音量等级在[1级，8级]范围内时，听筒和屏幕发声装置的发声强度比例为第一比例(例如3:7)。当系统音量等级在[9级，10级]范围内时，听筒和屏幕发声装置的发声强度比例为第二比例(例如7:3)。其中，第二比例大于第一比例。
还需要说明的，上述以音量等级从8级变化为9级以及音量等级从9级变化为8级为例进行示例性说明，在实际实现时，不限定是在8级和9级之间进行模式切换，还可以根据实际需求进行设置。例如，在实际实现时，还可以预先设置当音量等级在[1级，6级]音量等级范围内，此时启用隐私通话模式；当音量等级在[7级，10级]音量范围内，此时启用正常模式。在此情况下，音量等级从6级变化为7级，可以触发从隐私通话模式切换到正常模式；或者，音量等级从7级变化为6级，可以触发从正常模式切换到隐私通话模式。
还需要说明的是，本申请实施例是以根据音量等级的变化来触发在正常模式和隐私通话模式进行切换为例进行示例性说明的，例如当音量等级大于音量等级阈值时，切换为正常模式；当音量等级小于或等于音量等级阈值时，切换为隐私通话模式。可以理解，在实际实现时，还可以根据音量值的变化来触发在正常模式和隐私通话模式进行切换，例如当音量值(例如分贝值)大于音量阈值(如分贝阈值)时，切换为正常模式；当音量值小于或等于音量阈值时，切换为隐私通话模式。具体采用上述哪种方式可以根据实际使用需求确定，本申请实施例不作限定。
在本申请实施例中，可以通过音量条的形式来表示音量值的大小。下面基于上述音量等级划分的示例，说明本申请实施例中与各音量等级对应的音量条的可能形式。
示例性地，通过在音量条中以不同填充长度区分不同大小的音量等级，例如音量条中的填充越多，则表示音量等级越大，在此情况下语音输出音量越大。当音量条中被完全填充，对应10级，表示达到音量的最大值。当音量条没有被填充，表示静音。
可选地，本申请实施例不限定正常模式和隐私通话模式时，音量条的显示形式、显示颜色、显示长度等。
在本申请实施例中，可以通过不同的图标分别表示隐私通话模式和正常模式，以作区分。具体地，用于标识通话模式的图标在显示位置、显示尺寸以及显示形式等方面，可以根据实际使用需求确定，本申请实施例不作限定。可选地，用于标识通话模式的图标可以 显示于音量条的下方或上方。
示例性地，图10为基于图9所示的各个音量等级对应的音量条示意图。如图10中的(a)中所示，示出了1级到8级的音量条示意图，1级到8级音量均对应隐私通话模式。如图10中的(b)中所示，示出了9级到10级的音量条示意图，9级到10级音量均对应正常模式。
在一些实施例中，在隐私通话模式与正常模式之间切换时，在音量条的填充量发生变化的同时，通话模式的图标也会相应发生变化，以提示用户通话模式已切换，从而提升用户使用体验。
在一些实施例中，在隐私通话模式与正常模式之间切换时，电子设备可以通过显示具体提示信息来提示用户。
在一些实施例中，在隐私通话模式与正常模式之间切换时，电子设备可以震动提示用户，提升用户使用体验。
本申请实施例提供的通话控制方法，可以在来电接听时根据系统通话音量等级将接听音量自动调节到合适的音量等级并启用隐私通话模式，在通话过程中可以实现根据环境声大小自动切换模式，即在安静环境中自动切换到隐私通话模式并自动减小音量，由此可减少漏音；在嘈杂环境中自动切换到正常模式并自动增大音量，由此可保证通话清晰度；并且在通话过程中，还可以根据用户实际需要，响应于用户手动触发操作，在隐私通话模式与正常模式之间进行切换，因此本申请提供的自动调节方式和手动调节方式可以根据实际使用需求实现模式切换，满足各种场景下用户通话的需求。
对于隐私通话模式与正常模式之间的切换，本申请实施例提供了自动调节方式和手动调节方式，下面基于上述音量等级划分、音量条以及模式对应关系等基础内容，结合具体的实施例介绍本申请实施例提供的通话控制方法。
第一实施例：自动调节方式
在本申请实施例中，在来电场景下，电子设备获取系统设置的通话音量(简称为系统通话音量)，然后根据系统通话音量的大小来判断是否自动调节音量以及是否需要在隐私通话模式和正常模式之间进行模式调节。其中，系统通话音量可以为上一次挂断电话时的通话音量，或者用户在“声音和振动”设置界面中对“通话音量”调节后的音量。系统通话音量具体可以采用音量等级来衡量，例如，系统通话音量可以是1级到10级音量中的某一等级音量。
示例性地，在本申请实施例中，可以预设下述通话控制规则：
当系统通话音量在1级到8级音量范围内时，本次来电接通后的通话音量将保持系统通话音量，进入隐私通话模式。参考图11中的(a)和图11中的(b)所示，当系统通话音量为4级时，本次来电接通后的通话音量保持4级，进入隐私通话模式。当系统通话音量为7级时，本次来电接通后的通话音量保持7级，进入隐私通话模式。
当系统通话音量为9级或10级音量时，本次来电接通后的通话音量降低到预设音量(例如8级音量)，进入隐私通话模式。参考图11中的(c)所示，当系统通话音量为9级或10级时，本次来电接通后的通话音量自动调低到8级，进入隐私通话模式。
在本申请实施例中，在来电接通后的通话场景下，电子设备监测环境声(也称为环境噪声或者环境音或者环境噪音等)，然后电子设备根据环境声的大小来判断是否自动调节 音量，并且在音量调节时隐私通话模式和正常模式之间进行相应地切换。
在一种可能实现方式中，在来电接通后的通话场景下，在当前通话输出音量为A级音量(如8级或9级音量)时，才会触发电子设备采集环境声，然后根据环境声的大小来判断是否自动调节音量以及是进行模式调节。
例如，在当前通话输出音量为A级音量(如8级音量)时，电子设备采集环境声，然后根据环境声的大小来判断是否自动增大音量以及是否需要从隐私通话模式切换到正常模式。具体地，当环境声大于某一环境声阈值(如55dB)时，说明电子设备所处环境为嘈杂环境，需要电子设备以大音量输出对方通话语音，以保证通话清晰效果，在此情况下电子设备可以自动升高音量并从隐私通话模式切换到正常模式。需要说明的是，上述环境声阈值可以根据实际需求进行设置，本申请实施例对此不作限定。
再例如，在当前通话输出音量为B级音量(如9级音量)时，电子设备采集环境声，然后根据环境声的大小来判断是否自动减小音量以及是否需要从正常模式切换到隐私通话模式。具体地，当环境声小于或等于某一环境声阈值(如55dB)时，说明电子设备所处环境为安静环境，若以正常模式输出语音，则可能存在通话语音泄露的风险，有必要保证通话隐私，在此情况下电子设备可以自动切换到隐私通话模式并降低音量。
示例性地，图12示出了通过控制音量和模式体现本申请实施例提供的通话控制方法的示意图。
参考图12中的(a)所示，在当前系统通话音量为7级音量时，当来电接通时，听筒和屏幕发声装置以第一比例和7级音量发出声音，进入隐私通话模式。在通话过程中，一直处于隐私通话模式，环境声变化不会触发通话音量自动调节。
参考图12中的(b)所示，在系统通话音量为8级音量时，当来电接通时，听筒和屏幕发声装置以第一比例和8级音量发出声音，进入隐私通话模式。在通话过程中，电子设备监测环境声，当环境声大于环境声阈值(如55dB)时，电子设备将系统通话音量提升到9级音量，退出隐私通话模式，在此情况下听筒和屏幕发声装置以第二比例和9级音量发出声音。然后，如果环境声小于或等于环境声阈值，那么电子设备将系统通话音量降低到8级音量，再次进入隐私通话模式。
参考图12中的(c)所示，在系统通话音量为9级音量时，当来电接通时，听筒和屏幕发声装置以第一比例和8级音量发出声音，进入隐私通话模式。在通话过程中，电子设备监测环境声，当环境声大于环境声阈值(如55dB)时，电子设备将系统通话音量提升到9级音量，退出隐私通话模式，在此情况下听筒和屏幕发声装置以第二比例和9级音量发出声音。然后，如果环境声小于或等于环境声阈值，那么电子设备将系统通话音量降低到8级音量，再次进入隐私通话模式。
参考图12中的(d)所示，在系统通话音量为10级音量时，当来电接通时，听筒和屏幕发声装置以第一比例和8级音量发出声音，进入隐私通话模式。在通话过程中，电子设备监测环境声，当环境声大于环境声阈值(如55dB)时，电子设备将系统通话音量提升到9级音量，退出隐私通话模式，在此情况下听筒和屏幕发声装置以第二比例和9级音量发出声音。然后，如果环境声小于或等于环境声阈值，那么电子设备将系统通话音量降低到8级音量，再次进入隐私通话模式。
需要说明的是，如果接通来电前系统通话音量为9级或10级，那么电子设备可以在 接通来电前将音量调节到8级，也可以在来电接通后将音量调节到8级，具体可以根据实际需求进行设置，本申请实施例对此不做限定。

S106、基础服务获取系统通话音量。
其中，系统通话音量可以采用音量等级来衡量。例如系统通话音量的等级可以为1至10级中的任一等级。
S107、基础服务将系统通话音量(具体可以为音量等级)通知给决策中心。
S108、决策中心判断系统通话音量是否大于音量等级阈值。
示例性地，音量等级阈值可以取8级。
需要说明的是，下述的S109和S110择一执行。
S109、当系统通话音量大于音量等级阈值时，决策中心通知音量控制模块：将音量降低到8级，进入隐私通话模式。
例如，系统通话音量为9级，可以将音量调整为8级，进入隐私通话模式。
S110、当系统通话音量小于或等于音量等级阈值时，决策中心通知音量控制模块：保持系统通话音量。
例如，系统通话音量的等级可以为1级至8级中的任一项，假设系统通话音量为7级，那么可以保持系统通话音量为7级，进入隐私通话模式。
S111、通话APP接收到用户点击接听键的操作。
S112、通话APP向音量控制模块通知来电接通信号。
S113、音量控制模块向播放控制模块指示采用隐私通话模式。
S114、播放控制模块在通话时采用隐私通话模式输出语音。
示例性地，在此情况下，听筒和屏幕发声装置以第一比例和8级音量发出声音，或者以第一比例和8级以下的音量发出声音。
需要说明的是，由于S109和S110择一执行，因此S114在采用隐私通话模式输出语音时，通话时的接听音量等级会根据S109和S110择一执行的结果进行确定。
下面结合手机界面示意图，详细说明在来电接通时根据系统通话音量自动调节音量的 实现过程。
如图14中的(a)所示，电子设备接收到来电通知，并显示来电通知界面，该来电通知界面中显示有提示信息“智慧隐私通话模式”，表明智慧隐私通话功能已默认开启，一旦来电接通后即可采用“智慧隐私通话模式”输出语音。
响应于用户的接听操作，如图14中的(b)所示，电子设备接通来电，电子设备的听筒和屏幕发生装置以第一比例和6级音量发出声音，此时处于隐私通话模式。
示例性地，第一比例为3:7。需要说明的是，听筒和屏幕发生装置以第一比例和6级音量发出声音，是指听筒和屏幕发生装置共同发声，二者发声的总音量为6级音量；在总音量中，听筒的发声强度占比为3，屏幕发生装置的发声强度占比为7。
如图14中的(c)所示，电子设备接收到用户调高音量的操作。如图14中的(d)所示，电子设备调高音量，例如将音量调高到10级(或9级)，在此情况下电子设备的听筒和屏幕发生装置以第二比例和10级音量发出声音，此时退出隐私通话模式。其中，第二比例大于第一比例。
示例性地，第二比例为7:3。需要说明的是，听筒和屏幕发生装置以第二比例和10级音量发出声音，是指听筒和屏幕发生装置共同发声，二者发声的总音量为10级音量；在总音量中，听筒的发声强度占比为7，屏幕发生装置的发声强度占比为3。
如图14中的(e)所示，电子设备接收到用户挂断电话的操作，结束本次通话。
如图14中的(f)所示，电子设备再次接收到来电通知，并显示来电通知界面，同样，该来电通知界面中显示有提示信息“智慧隐私通话模式”，表明智慧隐私通话功能已默认开启，一旦来电接通后即可采用“智慧隐私通话模式”输出语音。
响应于用户的接听操作，如图14中的(g)所示，电子设备接通来电，电子设备的听筒和屏幕发生装置以第三比例和8级音量发出声音，此时处于隐私通话模式。其中，第三比例小于第二比例。并且，第三比例与第一比例可以相同，也可以不同。
示例性地，第三比例可以为4:6。需要说明的是，听筒和屏幕发生装置以第三比例和8级音量发出声音，是指听筒和屏幕发生装置共同发声，二者发声的总音量为8级音量；在总音量中，听筒的发声强度占比为4，屏幕发生装置的发声强度占比为6。
需要说明的是，图14中系统通话音量的具体音量等级以及听筒和屏幕发生装置的发声比例值均为示例性地说明，在实际实现时，可以根据实际情况进行设置或确认，本申请实施例不做限定。
在一些实施例中，电子设备在通话过程中可以持续采集环境声，并根据环境声大小变化自动调节音量。当环境声小于或等于预设环境声阈值且接听音量较大(例如9级)时，可以确定需要自动减小音量并进入隐私通话模式；当环境声大于预设环境声阈值且接听音量较小(例如8级)时，可以确定需要自动增大音量并退出隐私通话模式。
下面结合手机界面示意图，详细说明在来电接通后根据系统通话音量或者根据环境声大小变化自动调节音量的实现过程。不同于相关技术中在来电接通后按照默认方式采用“智慧隐私通话模式”预设的固定音量(例如固定音量6级)输出语音，本申请实施例中可以在来电接通时根据系统通话音量的大小对本次接听音量进行自动调节。在通话过程中，电子设备根据环境声的变化对不同场景(嘈杂场景或安静场景)下的接听音量进行自动调节。
如图15中的(a)所示，电子设备接收到来电通知，并显示来电通知界面，该来电通知界面中显示有提示信息“智慧隐私通话模式”，表明智慧隐私通话功能已默认开启，一旦来电接通后即可采用“智慧隐私通话模式”输出语音。
在一些实施例中，若在来电时判断出系统通话音量在隐私通话模式对应的音量范围内，例如系统通话音量为6级，相对较小，则无需在来电接听后进行调节，并且通话时保持该系统通话音量输出语音即可，以尽量满足用户的使用习惯。相应地，在用户点击接听按键后，如图15中的(b)所示，电子设备显示接听界面，该接听界面中仍然显示提示信息“智慧隐私通话模式”，表明本次通话已启用“智慧隐私通话模式”，当前音量仍然保持为6级。
在另一些实施例中，若在来电时判断出系统通话音量为9级，相对较大，已超出隐私通话模式对应的音量范围，则需要在来电接听后降低音量，这样在输出语音时可以尽量满足用户的使用习惯且能够保障通话隐私。在用户点击接听按键后，如图15中的(c)所示，电子设备显示接听界面，该接听界面中仍然显示提示信息“智慧隐私通话模式”，表明本次通话已启用“智慧隐私通话模式”，电子设备在后台自动将接听音量调节到8级。
在另一些实施例中，如图15中的(c)所示，假设当前接听音量为8级。当判断环境声小于或等于预设环境声阈值时，如图15中的(d)所示，电子设备保持接听音量8级，且保持“智慧隐私通话模式”。而当判断环境声大于预设环境声阈值时，如图15中的(e)所示，电子设备自动将接听音量增大到9级，自动退出“智慧隐私通话模式”，变为正常模式。如图15中的(e)所示，在正常模式下，通话界面中显示提示信息“调低音量可进入智慧隐私通话”，而不显示“智慧隐私通话模式”，并且通话界面中状态栏不再显示隐私通话图标。
需要说明的是，在实际实现时，在自动调节模式下在来电通知界面和接通界面中不显示音量条。电子设备调节音量均为后台完成，无需用户触发操作，提升了用户使用体验。
上面说明了在通话过程中从“智慧隐私通话模式”切换到正常模式的过程，可以理解，在实际实现时，用户接听环境可能随时变化，从安静环境变化为嘈杂环境，或者从嘈杂环境变化为安静环境，在此情况下，电子设备可以自动根据环境声判断是否进行模式切换及音量调节。图16示出了根据环境声变化自动切换模式的示意性流程图。结合图13，如图16所示，在S114之后，通话控制方法还包括S115-S119。
S115，决策中心判断环境声是否大于环境声阈值。
示例性地，环境声阈值可以取55dB。
需要说明的是，下述的S116-S118和S119择一执行。
S116，当环境声大于环境声阈值时，决策中心指示音量控制模块：切换为正常模式(音量等级升高到9级)。
S117，音量控制模块指示播放控制模块采用正常模式。
S118，播放控制模块在通话时采用正常模式输出语音。
S119，当环境声小于或等于环境声阈值时，决策中心确定保持隐私通话模式。
下面结合图17说明根据环境声大小变化，自动调节系统通话音量并相应地切换模式的过程。
如图17中的(a)所示，电子设备显示通话界面，当前接听音量为8级，采用隐私通 话模式进行语音输出，通话界面中显示有隐私通话图标和提示信息。如图17中的(b)所示，当环境声大于阈值时，自动退出智慧隐私通话模式，且自动提升音量(如降低到9级)，模式切换后的通话界面中隐私通话图标和提示信息消失。
如图17中的(b)所示，电子设备显示通话界面，当前接听音量为9级，采用正常模式进行语音输出。如图17中的(a)所示，当环境声小于或等于阈值时，自动切换到智慧隐私通话模式，且自动降低音量(如降低到8级)，模式切换后的通话界面中显示隐私通话图标和提示信息，表明本次通话已启用“智慧隐私通话模式”。
在一些实施例中，可以在当前采用隐私通话模式且检测到环境声大于环境声阈值且持续时长大于一定时长的情况下，从隐私通话模式切换到正常模式；或者，可以在当前采用正常模式且检测到环境声小于或等于环境声阈值且持续时长大于一定时长的情况下，从正常模式切换到隐私通话模式，这样可以避免短时间内来回进行模式切换，提升用户使用体验。
在一些实施例中，在拨打电话或者接到来电通知之前，用户可能会在设置界面中对通话音量进行调节；在此情况下，当来电或去电接通后，电子设备优先采用隐私通话模式。示例性地，如图18中的(a)和图18中的(b)所示，用户在声音和振动的设置界面中将通话音量调节到9级，如图18中的(c)和图18中的(d)所示，当来电(或去电)接通后，电子设备优先切换到隐私通话模式，并将9级音量自动调节到8级，并且听筒和屏幕发声装置共同发声，且以第一比例(例如3:7)，按照8级音量输出通话语音，并在后续通话过程中还可以根据环境声音量大小触发在隐私通话模式和正常模式之间切换。
在另一些实施例中，在拨打电话或者接到来电通知之前，用户可能会在设置界面中对通话音量进行调节。在此情况下，当下一次来电或去电接通后，电子设备可以保持用户设置的系统通话音量，直到用户在通话过程中调节通话的音量实现了两种模式之间的切换。在用户下次再接到来电通知或拨打电话的时候，电子设备根据系统通话音量的大小来判断是否自动调节音量以及是否需要在隐私通话模式和正常模式之间进行模式调节，如图11-图17所示的方法。
举例来说，在一次拨打电话或者接到来电通知之前，用户在设置界面中调节通话音量至10级，在用户拨打电话或者接到来电通知，接通通话后电子设备以10级音量和对应的比例(听筒和屏幕发声的比例)发出声音，在用户通过手动的方式在通话过程中调节音量到8级以下之前的一次或多次通过过程中，电子设备保持用户在系统设置中手动设置的音量，例如10级。在用户通过手动的方式在通话过程中调节音量到8级以下之后，电子设备进入隐私通话模式。并且，在下一次接收到来电通知或者拨打电话时，电子设备根据图11-图17所示的方法确定通话模式和音量。
第二实施例：手动调节方式
第二实施例是在第一实施例的基础上进一步增加的方案。需要说明的是，在隐私通话功能开启的情况下，电子设备可以自动决策是否调节音量以及是否调节模式。当用户触发调节音量或者触发调节模式时，则电子设备从自动调节方式切换到手动调节方式，然后按照用户手动调节方式进行音量及模式调节。
在一些实施例中，用户可以通过对电子设备的物理音量按键按压，触发降低音量或调高音量，进而触发将通话模式在隐私通话模式或者正常模式之间切换。
在另一些实施例中，用户可以通过在屏幕上显示的音量条上滑动操作，触发调高音量或降低音量，进而触发将通话模式在隐私通话模式或者正常模式之间切换。
示例性地，这里针对不同通话模式的切换进行描述。比如说，用户点击物理音量按键，电子设备响应于用户操作可以显示音量条。当用户调高音量时，音量条的填充量会增加，例如音量条从8级变化为9级，则自动退出隐私通话模式，并进入正常模式，即从隐私通话模式切换到正常模式。当用户调低音量时，音量条的填充量会减少，例如音量条从9级变化为8级，则从正常模式切换到隐私通话模式。
在本申请实施例中，通过本申请提供的通话控制方法，可以根据电子设备的输出音量等级或范围，控制隐私通话模式与正常模式切换使用。其中，针对隐私通话模式与正常模式的切换，电子设备可以预定义下述规则：
当电子设备的输出音量等级小于或等于预设音量等级(例如8级)时，或者当电子设备的输出音量等级在预设的第一音量等级范围内(例如[1级，8级])时，则自动启用隐私通话模式；当电子设备的输出音量等级大于预设音量等级时，或者当电子设备的输出音量等级在预设的第二音量等级范围内(例如[9级，10级])时，则自动退出隐私通话模式，并进入正常模式。其中，第二音量等级范围中各个等级对应的音量值大于第一音量等级范围中各个等级对应的音量值。
示例性地，当接收到用户降低音量或提高音量的操作时，若判断调节后的音量等级小于或等于预设音量等级(例如8级)，则启用隐私通话模式，例如可以通过屏幕和听筒同时发声并控制这两种发声方式以不同的音量强度进行发声(例如屏幕发声的强度大于听筒发声的强度)，以避免漏音，提升用户通话体验。若判断调节后的音量等级大于预设音量等级(例如8级)，则启用正常模式，例如可以通过屏幕和听筒同时发声并控制这两种发声方式以不同的音量强度进行发声(例如听筒发声的强度大于屏幕发声的强度)，以保证良好的出音效果，提升用户通话体验。
示例性地，图19示出了通过按压物理音量按键调节音量以触发模式切换的界面示意图。如图19中的(a)所示，假设当前接听音量等级为10级，用户可以通过按压电子设备的物理音量按键-键，触发降低音量。如图19中的(b)所示，电子设备响应于用户操作，将通话模式切换到隐私通话模式，并且在通话界面中显示音量条61以及隐私通话图标62，音量条61示出了音量降低变化，接听音量等级降低到例如6级。在隐私通话模式下可以保障通话隐私。类似地，如图19中的(c)所示，在通话界面中显示有音量条61以及隐私通话图标62。假设当前接听音量等级为6级，用户按压音量+键。然后，如图19中的(d)所示，电子设备响应于用户操作，将通话模式切换到正常模式，在通话界面中显示有音量条61以及大音量图标63。音量条61示出了音量提升变化，接听音量等级为9级。在正常模式下可以保障通话清晰性。
示例性地，图20示出了通过按压音量条调节音量以触发模式切换的界面示意图。如图19中的(a)和图19中的(b)所示，假设当前接听音量等级为9级，在接通界面中显示有音量条的情况下，用户可以通过拖动音量条上的调节按钮，触发降低音量。如图20中的(c)所示，音量降低到6级，通话模式从正常模式切换为隐私通话模式。如图20中的(d)所示，音量条61以及隐私通话图标62在一定时长后将自动隐藏。
需要说明的是，在用户通过电子设备进行贴耳听音的场景中，本申请提供的通话控制 方法可以在电子设备的输出音量等级降低后小于或等于预设音量等级时，启用隐私通话模式，以避免语音通话时漏音。在电子设备的输出音量等级升高后超过预设音量等级时，退出隐私通话模式，并进入正常模式，保证大音量播放效果。
在一些实施例中，在本次通话过程中，在切换到手动调节模式之后，将不再返回到自动调节模式，也就是说，在本次通话过程中将不再执行上述根据环境声大小自动调节音量及模式的方案。
在一些实施例中，假设在本次通话时切换到手动调节模式，那么在电子设备下一次接收到来电通知或者通话时，仍然默认先启用自动调节模式，也就是仍然会执行第一实施例中的方法。
第三实施例：来电场景操作物理音量键可触发电话接通后启用“智慧隐私通话模式”
目前只支持在电话接通场景中实现“智慧隐私通话模式”的启用和关闭，而在来电通知、未接通的场景中是无法实现对“智慧隐私通话模式”的操作设置的，无法实现对通话音量的调节，只能控制媒体音量。
鉴于此，本申请实施例提供了如下功能：在本次来电场景中，响应于用户按压音量键或者电源键的操作，电子设备可以在电话接通前启用“智慧隐私通话模式”或者“正常模式”，也就是说，在接通电话前实现对通话音量的调节。相比于相关技术中用户按压音量键或者电源键仅会触发来电铃声静音而言，本申请方案提供了更多能够触发启用“智慧隐私通话模式”的场景。
在一些实施例中，在未开启“智慧隐私通话模式”情况下，在来电接通前、来电通知时，电子设备可以响应于用户双击音量下键，快速启用“智慧隐私通话模式”。
示例性地，如图21中的(a)所示，电子设备接到来电，并显示来电通知界面，并且在屏幕预设区域(例如物理音量键附近)显示提示信息：“双击快速进入智慧隐私通话”。如图21中的(b)所示，如果接通来电前系统通话音量为9级或10级，那么用户双击音量下键后，电子设备可以调低通话音量，例如自动调低到8级，并且电子设备启用智慧隐私通话功能，并在来电通知界面中显示提示信息“已开启智慧隐私通话模式”。此时来电铃声静音。如图21中的(c)所示，当来电接通后，电子设备采用智慧隐私通话模式，以调低后的系统通话音量进行语音输出。
需要说明的是，如果在电子设备接通来电前，系统通话音量为8级及8级以下，那么在用户双击音量下键后，电子设备可以不调节系统通话音量。当来电接通后，电子设备采用智慧隐私通话模式，以未调整的系统通话音量进行语音输出。
作为比较示例，如图21中的(d)所示，在来电通知界面中显示提示信息：“双击音量下键可进入智慧隐私通话”的情况下，如图21中的(e)所示，如果用户在未双击音量下键后点击接听键，那么如图21中的(f)所示，电子设备在通话界面中显示提示信息“调低音量可进入隐私通话模式”，智慧隐私通话功能未被启用。
需要说明的是，如果接通来电前系统通话音量为9级或10级，那么在用户双击音量下键后，电子设备可以在接通来电前调节音量，也可以在来电接通后调节音量，具体可以根据实际需求进行设置，本申请实施例对此不做限定。
在一些实施例中，在来电接通前、来电通知时，响应于用户双击音量下键，电子设备可以直接自动接听来电，而无需用户点击接听控件，并且采用上述方式调低系统通话音量 或者保持系统通话音量，快速启用“智慧隐私通话模式”。
图22示出了本申请实施例提供的通话控制方法的另一时序示意图。如图22所示，通话控制方法包括S201至S210。其中涉及模块包括通话服务、通话APP、基础服务、播放控制模块以及音量控制模块。
S201、通话服务接收到来电信号。
需要说明的是，此时隐私通话功能未开启。
S202、通话服务响应于来电信号，启动通话APP。
相应地，通话APP启动，并触发在桌面显示来电通知界面，该来电通知界面中显示有接听键，该接听键用于触发接听来电。
S203、通话服务指示播放控制模块播放铃声。
相应地，播放控制模块播放来电铃声。
S204、基础服务接收到用户双击音量下键的操作。
S205、基础服务通知播放控制模式设置来电铃声静音。
S206、基础服务通知音量控制模式启用隐私通话模式。
示例性地，当系统通话音量为9级或10级时，在电子设备接收到来电通知时，若用户双击音量下键，则电子设备将系统通话音量降低到8级，在电话接通后会以8级音量输出声音。可以理解，由于8级音量对应的是隐私通话模式，因此相应地会自动启用隐私通话模式。
再示例性地，当系统通话音量在[1级，8级]范围内时，在电子设备接收到来电通知时，若用户双击音量下键，则电子设备保持系统通话音量。例如，在电子设备接收到来电通知时系统通话音量为6级，若用户双击音量下键，则电子设备保持系统通话音量为6级，在电话接通后会以6级音量输出声音。可以理解，由于6级音量对应的是隐私通话模式，因此相应地会自动启用隐私通话模式。
S207、通话APP接收到用户点击接听键的操作。
S208、通话APP向音量控制模块通知来电接通信号。
S209、音量控制模块向播放控制模块指示采用隐私通话模式。
S210、播放控制模块在通话时采用隐私通话模式输出语音。
在另一些实施例中，在未开启“智慧隐私通话模式”情况下，在来电时，电子设备可以响应于用户单击音量下键，来电铃声静音；电子设备可以响应于用户再次单击音量下键，在来电通知界面中显示音量条。用户通过在音量条操作以调节音量，可以触发“智慧隐私通话模式”快速启用。
示例性地，如图23中的(a)所示，电子设备接到来电，并显示来电通知界面，并且显示提示信息：“调低音量可进入智慧隐私通话”。如图23中的(b)所示，用户单击音量下键后，电子设备将来电铃声处理为静音。用户再次单击音量下键后，如图23中的(c)所示，电子设备在来电通知界面中显示音量条。如图23中的(d)所示，响应于用户在音量条上的操作，电子设备调低音量并启用智慧隐私通话功能，并如图23中的(e)所示，在来电通知界面中显示提示信息“已开启智慧隐私通话模式”。如图23中的(f)所示，当来电接通后，电子设备采用智慧隐私通话模式进行语音输出。
第四实施例：通过隐私通话开关快速启用或关闭“智慧隐私通话模式”
在一些实施例中，在来电通知界面中可以显示隐私通话开关，电子设备可以响应于用户对该隐私通话开关的操作，快速开启或关闭“智慧隐私通话模式”。在另一些实施例中，在来电接通的通话界面中同样可以显示隐私通话开关，电子设备可以响应于用户对该隐私通话开关的操作，快速开启或关闭“智慧隐私通话模式”。
示例性地，图24示出了在来电页面触发隐私通话开关的界面图。如图24中的(a)所示，电子设备接到来电，并显示来电通知界面，在来电通知界面中显示有隐私通话开关以及提示信息“已开启隐私通话模式，通话漏音更小。点击可关闭”。此时，隐私通话开关表示隐私通话模式为开启状态。如图24中的(b)和图24中的(c)所示，当用户点击该隐私通话开关后，该隐私通话开关更新显示状态(例如由深色变为浅色)，此时隐私通话开关表示隐私通话模式为关闭状态。并且，响应于用户关闭隐私通话的操作，电子设备在来电通知界面中显示音量条以及大音量图标。进一步地，当用户点击接听键后，如图24中的(d)所示，电子设备显示通话界面，在通话界面中仍然显示隐私通话开关。可选地，在隐私通话开关附近区域可以显示提示信息“点击可开启隐私通话模式，通话漏音更小”。
需要说明的是，本申请实施例中的隐私通话开关的显示方式仅仅是一个示例，本申请不限于此。比如说，还可以在显示界面顶部的状态栏中，以胶囊的形式显示隐私通话开关。
再示例性地，图25示出了在通话页面触发隐私通话开关的界面图。如图25中的(a)所示，电子设备显示通话界面，在通话界面中显示有隐私通话开关以及提示信息“点击可开启隐私通话模式，通话漏音更小”。此时隐私通话开关表示隐私通话模式为关闭状态。如图25中的(b)和图25中的(c)所示，当用户点击该隐私通话开关后，该隐私通话开关更新显示状态，隐私通话开关表示隐私通话模式为开启状态(例如由浅色变为深色)。并且，响应于用户开启隐私通话的操作，电子设备在来电通知界面中显示音量条以及通话隐私图标。在通话过程中，电子设备采用隐私通话模式进行语音输出。可选地，在隐私通话开关附近区域可以显示提示信息“已开启隐私通话模式，通话漏音更小。点击可关闭”。如图25中的(d)所示，音量条在一定时长后将自动隐藏。
需要说明的是，以上实施例是以来电场景为例进行说明的，在实际实现时，上述实施例同样适用于去电场景。例如，在去电界面中可以显示隐私通话开关，电子设备可以响应于用户对该隐私通话开关的操作，快速开启或关闭“智慧隐私通话模式”。并且，在去电接通后的通话界面中同样可以显示隐私通话开关，电子设备可以响应于用户对该隐私通话开关的操作，快速开启或关闭“智慧隐私通话模式”。
第五实施例：在来电接通时弹出音量条以及模式调节提示
在一些实施例中，在未开启“智慧隐私通话模式”情况下，在来电接通时，在通话界面中立刻弹出音量条以及提示信息“调低音量进入智慧隐私通话模式”。用户可以根据实际使用需求，选择调低音量触发电子设备启用智慧隐私通话模式，或者不调节音量，从而不启用智慧隐私通话模式。
示例性地，图26示出了在来电通话页面提示开启隐私通话模式的界面图。如图26中的(a)所示，电子设备接到来电，并显示来电页面。当用户点击接听键后，如图26中的(b)所示，电子设备显示通话界面，并且该通话界面中显示有音量条、大音量图标以及提示信息“调低音量进入智慧隐私通话模式”。在此情况下，用户可以有如下两种选择：如图26中的(c)和图26中的(d)所示，用户在音量条上操作以降低音量，可触发进入 隐私通话模式；或者，如图26中的(e)所示，用户在通话界面上不操作或者点击在通话界面的空白处，则不会进入隐私通话模式。
需要说明的是，以上实施例是以来电场景为例进行说明的，在实际实现时，上述实施例同样适用于去电场景。在一些实施例中，在未开启“智慧隐私通话模式”情况下，在去电接通，且电子设备未贴耳时，在通话界面中可以立刻弹出音量条以及提示信息“调低音量进入智慧隐私通话模式”，以引导用户通过调节音量条来启用智慧隐私通话模式。用户可以根据实际使用需求，选择调低音量触发电子设备启用智慧隐私通话模式。在一些实施例中，在未开启“智慧隐私通话模式”情况下，在去电接通，且电子设备贴耳时，电子设备可以控制显示屏熄灭，防止误触。
示例性地，图27示出了在去电通话页面提示开启隐私通话模式的界面图。如图27中的(a)所示，电子设备显示去电页面。当电话接通后，如图27中的(b)所示，电子设备显示通话界面，并且该通话界面中显示有音量条、大音量图标以及提示信息“调低音量进入智慧隐私通话模式”。在此情况下，用户可以有如下两种选择：如图27中的(c)和图27中的(d)所示，用户在音量条上操作以降低音量，可触发进入隐私通话模式；或者，如图27中的(e)所示，用户在通话界面上不操作或者点击在通话界面的空白处，则不会进入隐私通话模式。
在本申请实施例中，在智慧隐私通话功能开启之后，在语音通话场景中，隐私通话模式可以在电子设备的输出音量等级低于预设音量等级时自动启用。也就是说，在语音通话场景中当电子设备的输出音量等级低于预设音量等级时，则自动切换为隐私通话模式，并采用隐私通话模式对应的语音输出方式(例如通过屏幕和听筒共同发声，如屏幕发声强度大于听筒发声强度)来输出语音，避免语音通话时漏音。
在另一些实施例中，在语音通话场景中，当感应到用户连续多次触发音量降低的操作时，也可以自动切换为隐私通话模式，并采用隐私通话模式对应的语音输出方式(例如通过屏幕和听筒共同发声，如屏幕发声强度大于听筒发声强度)来输出语音，避免语音通话时漏音。
在一些实施例中，当从隐私通话模式切换到正常模式时，还可以在隐私通话模式对应的音量基础上，增大整体发声音量(或称为响度或强度)，以提升语音播放效果。也就是说，在正常模式下通过听筒发声和屏幕发声时的整体发声响度，大于在隐私通话模式下通过听筒发声和屏幕发声时的整体发声响度。
相比于听筒发声方式，屏幕发声方式能有效防止语音通话时漏音，因此当用户处于安静环境中接打电话时，用户通常希望减少漏音，此时可以采用隐私通话模式，能够保证通话清晰的同时，减少漏音，从而起到保护用户隐私的效果。
以上详细描述了隐私通话模式与正常模式之间切换的过程，下面再进一步说明隐私通话模式与扬声器模式之间切换的可能实现方式。
在一些实施例中，通过本申请提供的音频处理方法，在电子设备处于隐私通话模式的情况下，当电子设备接收到用户点击扬声器图标时，可以切换为扬声器模式，即通过扬声器发声来输出语音，此时屏幕和听筒均不发声。可选地，进一步地，当电子设备接收到用户点击扬声器图标时，可以退出扬声器模式，并重新进入隐私通话模式。
示例性地，图28示出了接听来电后的语音通话界面的示意图，在语音通话界面中显 示有以下提示信息：“智慧隐私通话已开启”71以及标识隐私通话的图标72。如图28中的(a)所示，用户点击语音通话界面中的扬声器键73，以触发通过扬声器播放语音。如图28中的(b)所示，响应于用户对扬声器键73的操作，手机开启免提功能，此时通过扬声器播放语音，且屏幕和听筒均不发声，并且语音通话界面中可以显示提示信息“已退出智慧隐私通话”74，相应地“智慧隐私通话已开启”71以及标识隐私通话的图标72会取消显示。提示信息“已退出智慧隐私通话”74在显示一定时长(例如5秒)后会隐藏。
进一步可选地，如图28中的(c)所示，用户可以再次点击语音通话界面中的扬声器键73，以触发关闭扬声器。如图28中的(d)所示，响应于用户对扬声器键73的操作，手机从扬声器模式切换到隐私通话模式。如此实现隐私通话模式与正常模式之间的切换。
再示例性地，图29示出了通过在智慧隐私通话功能的通知卡片上操作来触发从隐私通话模式切换到扬声器模式的界面示意图，如图29中的(a)所示，用户在语音通话界面上沿箭头方向向下滑动手指，以下拉菜单栏。如图29中的(b)所示，显示菜单栏(也称为通知界面)，该菜单栏中显示有通知卡片75，该通知卡片75用于指示正在进行语音通话，用户可以点击该通知卡片75中的免提标识76，以触发开启免提功能。如图29中的(c)所示，在用户点击该免提标识76之后，从菜单栏界面返回到语音通话界面，在语音通话界面中可以显示提示信息“已退出智慧隐私通话”74。相应地“智慧隐私通话已开启”71以及标识隐私通话的图标72会取消显示。如此实现隐私通话模式与正常模式之间的切换。
在一些实施例中，电子设备提供了智慧隐私通话功能的设置界面，用户可以根据实际使用需求，在该设置界面中触发智慧隐私通话功能开启或关闭。
示例性地，图30示出了通过智慧隐私通话功能的通知卡片进入智慧隐私通话功能的设置界面的示意图，如图30中的(a)所示，用户在语音通话界面上沿箭头方向向下滑动手指，以下拉菜单栏。如图30中的(b)所示，显示菜单栏(也称为通知界面)，该菜单栏中显示有通知卡片77，该通知卡片77用于指示智慧隐私通话功能已开启，用户可以点击该通知卡片77，以对智慧隐私通话功能进行设置。如图30中的(c)所示，在用户点击该通知卡片75之后，从菜单栏界面跳转到智慧隐私通话功能的设置界面78，该设置界面78中包括智慧隐私通话功能的开关控件79，开关控件79当前指示智慧隐私通话功能处于开启状态。用户可以对开关控件79操作(例如沿图示箭头方向的滑动操作)，以触发关闭智慧隐私通话功能。
进一步地，如图30中的(d)所示，在用户对开关控件79操作之后，退出隐私通话模式，并且从智慧隐私通话功能的设置界面78跳转到语音通话界面，在语音通话界面中可以显示提示信息“已退出智慧隐私通话”74。相应地“智慧隐私通话已开启”71以及标识隐私通话的图标72会取消显示。
需要说明的是，上面实施例应用的语音通话场景为例进行示例性的说明，可以理解，上述实施例提供的关于在隐私通话模式与扬声器模式之间切换，以及对隐私通话模式的功能设置等方案同样可以应用于VoIP的语音通话场景中。
如此，在用户通过电子设备进行贴耳听音时，电子设备可以根据不同的音量等级判断是启用隐私通话模式还是正常模式，并且可以选择通过听筒和/或屏幕进行发声。例如，在电子设备默认设置的音量等级或者用户触发调整后的音量等级小于或等于预设音量等级时，启用隐私通话模式，在隐私通话模式下可以通过听筒和屏幕以不同的发声强度播放语 音，例如屏幕发声强度大于听筒发声强度。在电子设备默认设置的音量等级或者用户触发调整后的音量等级大于预设音量等级时，则启用正常模式，在正常模式下也可以通过听筒和屏幕以不同的发声强度播放语音，例如听筒发声强度大于屏幕发声强度。通过听筒发声和屏幕发声互补使用，以使电子设备播放语音时既可以避免安静环境下漏音还可以具有良好音质。从而能够良好的保护用户的隐私，使电子设备在用户进行贴耳听音时具有更好的私密性。
如上所述，在用户通过手机进行贴耳听音，或用户选择听筒模式(即手机通过听筒播放声音的模式)时，手机可以判断当前的音量等级是否大于预设音量等级，并根据判断结果确定是启用隐私通话模式还是启用正常模式。下面说明如何检测用户通过手机贴耳听音的动作的可能实现方式。
其中，用户通过手机进行贴耳听音(即手机所处的贴耳听音状态)，可以是用户耳朵贴靠在听筒附近，通过手机的听筒收听手机内存储的音频数据(如录音数据、歌曲数据等)。还可以是用户耳朵贴靠在听筒附近进行语音通信(语音通信可以是通过手机中的电话功能与其他电子设备进行的语音通信，也可以是通过手机中安装的即时通讯应用与其他电子设备进行的语音通信)时，通过手机的听筒收听手机接收到的对侧用户手机传输来的声音数据。还可以是用户耳朵贴靠在听筒附近，通过手机的听筒收听即时通讯应用中的语音消息等。如，手机通过即时通讯应用接收来自其他手机的语音消息。手机可以显示即时通讯应用的聊天界面，该聊天界面包括来自其他手机的语音消息。响应于用户对该语音消息的点击操作，手机可以通过听筒播放来自其他手机的语音消息(即声音信号)。
示例地，手机可以通过光线传感器、距离传感器等传感器来检测用户耳朵是否贴靠在听筒附近。例如，手机可以通过距离传感器检测手机前面板(或者屏幕)前是否有遮挡，当前面板前近距离处有遮挡，则可确定当前用户耳朵贴靠在听筒附近。又例如，当手机光线传感器检测到光线强度瞬间降低且变化较大时，则可确定当前用户耳朵贴靠在听筒附近。当然，在本申请的其他实施例中，手机还可以通过其他方式或算法检测用户耳朵是否贴靠在听筒附近，也可以参考常规技术中的相关介绍，此处不做限制。
在一些实施例中，当用户使用手机进行贴耳听音时，手机还可以显示可供用户选择的各种听音模式，以便用户根据实际使用需求，手动选择听音模式，触发手机执行相应的听筒和屏幕发声的声音播放策略。其中，听音模式可以包括隐私通话模式和正常模式。
需要说明的是，上述示例中，手机接收到用户输入的选择听音模式的操作后，可以直接采用相对应的声音播放策略来播放声音。每种听音模式采用对应的声音播放策略。
其中，隐私通话模式可以采用听筒和屏幕共同发声的声音播放策略来播放声音，其中屏幕发声强度可以大于或等于听筒发声强度。即，手机可以采用屏幕发声为主、听筒发声为辅的方式同时播放语音。隐私通话模式还可以仅采用屏幕发声。
其中，正常模式可以采用听筒和屏幕共同发声的声音播放策略来播放声音，其中听筒发声强度可以大于屏幕发声强度。即，手机可以采用听筒发声为主、屏幕发声为辅的方式同时播放语音。正常模式还可以仅采用听筒发声。
其中，根据上述示例的用户贴耳听音的各种场景，听筒和屏幕发声播放的语音可以是手机中保存的任一个音频数据，例如，语音是手机中保存的录音数据或歌曲数据等。还可以是手机进行语音通信时手机接收到的对侧用户手机传输来的声音数据。还可以是手机中 安装的即时通讯应用中的语音消息等。
图31为本申请实施例提供的一种通话控制方法的提示隐私通话功能的流程示意图。如图31所示，在前三次接听后或者拨打电话，未进入隐私通话模式的情况下，在来电通知界面或者去电界面中弹出气泡提示(如上述图5所示的气泡提示)。进一步判断是否进入隐私通话模式。如果检测到没有进入隐私通话模式，那么表示用户未学会隐私通话功能，因此电子设备通过弹出气泡来提示，例如提示三次。如果检测到进入隐私通话模式，那么表示用户已学会该功能。进一步地，判断在某一预设时长(如7天)内，用户是否有多次(如两次)以上触发进入隐私通话模式。如果检测到没有进入隐私通话模式，那么表示用户仍未学会隐私通话功能，因此电子设备再次弹出三次气泡进行提示，直到用户学会该隐私通话功能为止停止提示。如果检测到进入隐私通话模式，那么表示用户已学会该功能，不再进行提示。
可选地，在本申请实施例中，安静环境下，手机还可以根据人耳与手机(或听筒)间的距离来调整听筒发声和屏幕发声的音量(或称为响度)。同时，还可以对听筒发声输出的频段以及屏幕发声输出的频段进行调整。
例如，当人耳远离手机时，手机可以增加听筒发声和屏幕发声的音量。同时，手机还可以减少听筒发声输出的频段中相对高频的部分的发声，即降低屏幕发声输出的频段和听筒发声输出的频段间的分界频率，使听筒发声输出更低的频段。由于屏幕发声的能量大部分正对人耳，而听筒发声的部分能量会从手机中框顶部的出音孔释放，因此提高音量后听筒发声相比于屏幕发声更易漏音，所以进一步调低听筒发声输出的频段，能够避免提高音量后其他用户听清听筒发声输出的声音。
在一些实施例中，还可以根据屏幕发声的灵敏度对屏幕发声的声音强度进行设置。即，根据屏幕发声的灵敏度不同，设置的屏幕发声的声音强度也可以有所不同。
例如，在本申请实施例中，屏幕发声可以通过屏幕发声装置(例如，如图2所示的屏幕发声装置)实现，根据不同的屏幕发声方案，屏幕发声装置也有所不同。如，屏幕发声装置可以是连接在屏幕背面的振动源(通常为压电陶瓷，也可以是马达振子、激励器或其他振动单元)，可以通过电流信号控制压电陶瓷振动以带动屏幕振动，从而实现屏幕发声。又如，屏幕发声装置还可以是通过悬臂梁结构固定在手机中框上的压电陶瓷，可以通过电流信号控制压电陶瓷振动，利用手机中框将振动传递至屏幕带动屏幕振动，从而实现屏幕发声。又如，屏幕发声装置还可以是固定在手机中框上的激励器，可以通过电流信号控制激励器振动，利用手机中框将振动传递至屏幕带动屏幕振动，从而实现屏幕发声。又例如，屏幕发声装置还可以分体式磁悬浮振子。其中一个振子固定在手机中框上，另一个振子固定在屏幕上，可以通过电流信号控制固定在屏幕上的振子相对于固定在手机中框上的振子振动，从而推动屏幕振动实现屏幕发声。受屏幕发声装置设置的类型、位置、手机中框重量、手机内部结构布局等的影响，不同的屏幕发声方案的屏幕发声灵敏度均有所不同，可以为灵敏高的屏幕发声设置相对较小的屏幕发声声音强度和推动功率，而为灵敏度低的屏幕发声设置相对较大的屏幕发声声音强度和推动功率。
可选地，在本申请实施例中，电子设备(如手机)可以自动开启上述方法所实现的功能，也可以设置为用户手动开启上述方法所实现的功能。
