本发明涉及移动终端技术领域，具体涉及一种主耳机切换方法、移动终端以及计算机可读存储介质。
背景技术
随着无线技术的成熟，无线耳机通过无线技术连接手机等移动终端的场景越来越多。人们可以通过无线耳机实现听音乐、打电话等各种功能。一般而言，一幅无线耳机可以由主耳机和从耳机组成，主耳机与手机建立数据传输链路之后，主耳机将接收到的音频数据同步到从耳机后进行播放。在通话场景中，如果主耳机因主耳机距离变动等原因导致其不再适合继续做主耳机的情况下，主从耳机会发生切换，主从耳机切换的过程中，会造成短时通话中断，影响用户通话体验。

在一种可能的实现方式中，无线耳机还可以包括触摸区，该触摸区可以位于在耳机外壳的外部表面，触摸区内设置有至少一个触摸传感器，用于检测触摸操作，触摸传感器可以包括电容传感器。当用户触摸触摸区时，至少一个电容传感器可以检测到自身电容的变化从而识别触摸操作。

请参阅图2，图2是本申请实施例公开的一种主耳机切换方法的流程示意图，如图2所示，该主耳机切换方法包括如下步骤。
201，在移动终端处于通话状态时，移动终端检测是否满足主耳机切换条件。
本申请实施例中，通话状态，指的是移动终端处于电话接通的状态。在移动终端处于通话状态下，第一用户通过移动终端与第二用户通话，其中，第一用户使用移动终端接收第二用户发送的语音通话数据，第一用户可以通过移动终端向第二用户发送语音通话数据。语音通话数据指的是第一用户与第二用户通话过程中发出的语音数据。
当移动终端与一对无线耳机通信时，为了节省移动终端的功耗，降低移动终端的通信复杂度，移动终端只与其中一个耳机建立通信连接，与移动终端建立通信连接的耳机称为主耳机，主耳机不仅与移动终端建立通信连接，还与从耳机建立通信连接，主耳机接收移动终端发送的音频数据后，会同步给从耳机进行播放。
例如，无线耳机包括第一耳机和第二耳机，移动终端与无线耳机的第一耳机建立通信连接，无线耳机的第一耳机与无线耳机的第二耳机建立通信连接。无线耳机由一对耳机(第 一耳机和第二耳机)组成，其中，第一耳机为主耳机，第二耳机为从耳机。主耳机为与移动终端建立通信连接的耳机，从耳机为不与移动终端直接连接的耳机，从耳机与主耳机建立通信连接。其中，通信连接可以为蓝牙连接。
主耳机切换条件可以根据移动终端与第一耳机之间通信质量来确定。如果移动终端与第一耳机之间通信质量较差，则将主耳机从第一耳机切换至第二耳机。
比如，移动终端与第一耳机连接时，可以获取移动终端接收第一耳机的第一接收信号强度指示(Received Signal Strength Indicator，RSSI)，第一RSSI用于衡量移动终端接收第一耳机的信号强度的大小，RSSI的单位可以为dBm或者asu。其中dBm表示功率绝对值，信号强度一般为负数，其绝对值数值越小，表示信号强度越强。asu是定义的特有信号单位，数值越大，表示信号强度越强。如果第一RSSI低于预设强度阈值，则认为满足主耳机切换条件。
其中，预设强度阈值可以预先进行设定并存储在移动终端的非易失性存储器中，比如，预设强度阈值可以设置为-95dBm。
可选的，主耳机切换条件可以根据第一耳机和第二耳机的电量来确定。比如，当第一耳机为主耳机时，移动终端可以获取第一耳机的剩余电量以及第二耳机的剩余电量。如果第一耳机的剩余电量小于第二耳机的剩余电量，并且第一耳机的剩余电量与第二耳机的剩余电量的差值大于预设电量阈值，则认为满足主耳机切换条件。
其中，预设电量阈值可以预先进行设定并存储在移动终端的非易失性存储器中，比如，预设电量阈值可以设置为耳机电池容量的20％。
可选的，步骤201中移动终端检测是否满足主耳机切换条件，具体为：
移动终端检测移动终端与第一耳机的第一距离，检测移动终端与第二耳机的第二距离，检测第一耳机与第二耳机的第三距离；
移动终端在第一距离大于第二距离，以及第三距离大于或等于第一阈值的情况下，确定满足主耳机切换条件。
在本申请的一实现方式中，移动终端检测移动终端与第一耳机的第一距离，移动终端与第二耳机的第二距离，以及第一耳机与第二耳机的第三距离的具体实现方式有：移动终端获取第一耳机的第一位置、第二耳机的第二位置以及移动终端的第三位置；移动终端根据第一位置和第三位置确定移动终端与第一耳机的第一距离；移动终端根据第二位置和第三位置确定移动终端与第二耳机的第二距离；移动终端根据第一位置和第二位置确定第一耳机与第二耳机的第三距离。
具体地，移动终端可直接通过wifi定位技术确定自己的位置，但是第一耳机的位置和第二耳机的位置移动终端自己无法通过wifi定位技术得到。
其中，移动终端确定第一耳机的位置和第二耳机的位置的具体实现方式有：第二耳机通过wifi定位确定第二耳机的位置，以及第二耳机周期性的向第一耳机上报第二耳机的位置；第一耳机在接收第二耳机上报的第二耳机的位置之后，第一耳机通过wifi定位确定第一耳机的位置，以及第一耳机向移动终端上报第一耳机的位置和第二耳机的位置；移动终端接收第一耳机上报的第一耳机的位置和第二耳机的位置。
进一步地，移动终端确定移动终端的第三位置的具体实现方式有：在接收到第一耳机上报的第一耳机的位置和第二耳机的位置之后，移动终端再通过wifi定位确定移动终端的位置。
需要说明的是，在本申请中，移动终端也可以先确定第三位置再确定第一位置和第二位置，在此不作限定。移动终端进行wifi定位、第一耳机进行wifi定位和第二耳机进行wifi定位所使用的无线接入点是相同的。上述移动终端的位置、第一耳机的位置和第二耳机的位置均是位置坐标。在知道两点的位置的情况下，确定两点的距离是现有技术，在此不作 叙述。
在本申请的一实现方式中，移动终端检测移动终端与第一耳机的第一距离，移动终端与第二耳机的第二距离，以及第一耳机与第二耳机的第三距离的具体实现方式有：移动终端确定所述第一耳机与所述移动终端的第一RSSI值，以及根据所述第一RSSI值确定所述第一距离；移动终端确实所述第二耳机与所述移动终端的第二RSSI值，以及根据所述第二RSSI值确定所述第二距离；移动终端确定所述第一耳机与所述第二耳机的第三RSSI值，以及根据所述第三RSSI值确定所述第三距离。
具体地，由于移动终端与第一耳机连接，移动终端可直接得到移动终端与第一耳机的第一RSSI值，但是移动终端无法直接得到移动终端与第二耳机的第二RSSI值和第一耳机与第二耳机的第三RSSI值。
其中，移动终端确定第一耳机与第二耳机的第三RSSI值的具体实现方式有：第一耳机确定第一耳机与第二耳机的第三RSSI值，第一耳机将第三RSSI值发送给移动终端，移动终端接收第一耳机发送的第三RSSI值；或者，移动终端向第一耳机发送RSSI值获取请求，在接收到该RSSI值获取请求之后，第一耳机确定第一耳机与第二耳机的第三RSSI值，第一耳机将第三RSSI值发送给移动终端，移动终端接收第一耳机发送的第三RSSI值。
其中，移动终端确定移动终端与第二耳机的第二RSSI值的具体实现方式有：第二耳机通过蓝牙低功耗(Blluetooth Low Energy，BLE)广播方式周期性的向移动终端发送BLE广播；移动终端接收到第二耳机发送的BLE广播后，可得到第二耳机与移动终端的第二RSSI值。
移动终端根据RSSI值确定距离的具体实现方式有：移动终端根据RSSI值与距离的映射关系确定该RSSI值对应的距离。在RSSI值与距离的映射关系中，RSSI值与距离成反比，RSSI值越大对应的距离越小，RSSI值越小对应的距离越大。
进一步地，移动终端检测第一距离、第二距离和第三距离的顺序具体可以有：移动终端在接收到第二耳机发送的BLE广播后，得到了第二RSSI值，移动终端先基于第二RSSI值确定第二距离；然后移动终端向第一耳机发送RSSI值获取请求，第一耳机在接收到该RSSI获取请求之后，第一耳机确定第三RSSI值，以及将第三RSSI值发送给移动终端，接收第一耳机发送的第三RSSI值，移动终端先基于第三RSSI值确定第三距离；最后移动终端确定第一RSSI值，然后基于第一RSSI值确定第一距离。
当然，在本申请中，移动终端也可以先检测第一距离、然后第二距离，最后第三距离，或者可以先检测第三距离、再确定第一距离、最后确定第二距离，在此不作限定。
本申请实施例中，移动终端不仅要检测第一距离和第二距离，还要检测第三距离，其目的是为了防止出现乒乓切换的情况，防止出现移动终端反复进行主耳机切换的情况。当第三距离小于第一阈值的情况下，表明第一耳机和第二耳机距离较近，即使进行主耳机切换，也不会明显改善主耳机的通信质量，因此，本申请需要在第一距离大于第二距离，以及第三距离大于或等于第一阈值的情况下，确定满足主耳机切换条件。其中，第一阈值可以预先进行设定并存储在移动终端的存储器中。比如，第一阈值可以设置为50厘米。
202，若满足主耳机切换条件，移动终端基于语音通话数据预测至少一个通话空闲时间窗。
本申请实施例中，通话空闲时间窗，指的是语音通话过程中通话双方都没有发出语音的时间段。该通话空闲时间窗的时长可能是0.5秒，也可能是1秒、2秒等，本申请实施例不做限定。由于不同的用户在通话时的说话习惯、语速等不同，不同的通话双方，其通话空闲时间窗的时长都可能不同。即使是相同的通话双方，通话双方的情绪状态不同，其通话空闲时间窗的时长都可能不同。
其中，移动终端基于语音通话数据预测至少一个通话空闲时间窗，具体为：
移动终端基于语音通话数据推测通话双方下一次出现语音停顿的时间点，以及预测下一次出现语音停顿的语音停顿时长；
当下一次出现语音停顿的语音停顿时长大于预设时长时，将下一次出现语音停顿的时间段作为一个通话空闲时间窗，将下一次出现语音停顿的时间点作为上述通话空闲时间窗的起点。
本申请实施例中，语音通话数据指的是通话双方在通话过程中发出的语音数据。语音通话数据的持续时长为固定值(比如，100ms)。
移动终端可以识别语音通话数据是否符合语音停顿模型。如果符合语音停顿模型，则可以根据语音停顿模型中的停顿参数确定下一次出现语音停顿的语音停顿时长。其中，语音停顿模型可以根据多个语音样本训练得到。停顿参数可以包括下一次出现语音停顿的时间点以及下一次出现语音停顿的语音停顿时长。语音样本可以包括预先采集的包含停顿的用户语音。语音停顿模型可以包括语音特征，语音特征可以包括语音振幅、语音频率、语音振幅变化趋势、语调等。
停顿时长，指的是语音通话数据中语音振幅连续低于预设振幅阈值的一段时长。举例来说，当通话双方在通话过程中，将通话双方的其中一方说出一句话后的停顿的持续时长为停顿时长。
移动终端识别语音通话数据是否符合语音停顿模型，具体为：
移动终端提取语音通话数据中的语音特征，计算语音通话数据中的语音特征与语音停顿模型中的语音特征的匹配度是否大于预设匹配度，若大于，则认为语音通话数据符合上述语音停顿模型。
可选的，语音通话数据为第一用户与第二用户之间的语音通话数据，第一用户为移动终端的使用用户，上述步骤202中移动终端基于语音通话数据预测至少一个通话空闲时间窗，具体为：
移动终端预设第一用户向第二用户发出语音数据中的停顿时长为通话空闲时间窗；或者，
移动终端预设第二用户向第一用户发出语音数据中的停顿时长为通话空闲时间窗；或者，
移动终端预设第一用户向第二用户发出语音数据中的停顿时长和第二用户向第一用户发出语音数据中的停顿时长通话空闲时间窗。
本申请实施例中，移动终端可以将第一用户说完一句话后的停顿时长为通话空闲时间窗，也可以将第二用户说完一句话后的停顿时长为通话空闲时间窗，本申请实施例不做限定。本申请实施例可以将第一用户或第二用户说完一句话后的停顿时长，避免一句话没有说完就进行主耳机切换，避免出现语音通话的过程中进行主耳机切换而丢失重要语音数据的情况，尽量降低主耳机切换对通话的影响。
可选的，语音通话数据为第一用户与第二用户之间的语音通话数据，第一用户为移动终端的使用用户，基于语音通话数据预测至少一个通话空闲时间窗，包括：
移动终端获取第一用户与第二用户的历史通话记录中第一用户的第一平均停顿时长以及第二用户的第二平均停顿时长；
若第一平均停顿时长大于第二平均停顿时长，移动终端预设第一用户向第二用户发出语音数据中的停顿时长为通话空闲时间窗；
若第二平均停顿时长大于第一平均停顿时长，移动终端预设第二用户向第一用户发出语音数据中的停顿时长为通话空闲时间窗。
本申请实施例中，移动终端可以比较第一用户说完一句话后的平均停顿时长与第二用户说完一句话后的平均停顿时长的大小，选择将平均停顿时长较大的停顿时长作为通话空 闲时间窗，以使移动终端处于通话状态时能够有更加充足的时间在通话空闲时间窗进行主耳机切换，避免出现由于主耳机切换而丢失重要语音数据的情况，从而降低主耳机切换对通话的影响。
可选的，语音通话数据为第一用户与第二用户之间的语音通话数据，第一用户为移动终端的使用用户，基于语音通话数据预测至少一个通话空闲时间窗，包括：
获取第一用户的第一语速，获取第二用户的第二语速；
若第一语速大于第二语速，预设第二用户向第一用户发出语音数据中的停顿时长为通话空闲时间窗；
若第二语速大于第一语速，预设第一用户向第二用户发出语音数据中的停顿时长为通话空闲时间窗。
本申请实施例中，移动终端可以比较第一用户的说话语速与第二用户的说话语速。一般而言，说话语速较快的用户，其语间停顿较短，说话语速较慢的用户，其预见停顿较长。本申请实施例选择在说话语速较慢的用户说完一句话后的停顿时长作为通话空闲时间窗，以使移动终端处于通话状态时能够有更加充足的时间在通话空闲时间窗进行主耳机切换，避免出现由于主耳机切换而丢失重要语音数据的情况，从而降低主耳机切换对通话的影响。
203，移动终端在第一通话空闲时间窗内断开移动终端与第一耳机的通信连接，建立移动终端与第二耳机的通信连接，第一通话空闲时间窗为至少一个通话空闲时间窗中的任一个。
本申请实施例中，断开移动终端与第一耳机的通信连接，建立移动终端与第二耳机的通信连接，即为将移动终端的主耳机从第一耳机切换至第二耳机。第一通话空闲时间窗的持续时长大于移动终端执行步骤“断开移动终端与第一耳机的通信连接，建立移动终端与第二耳机的通信连接”的时长。
其中，若不满足主耳机切换条件，则可以继续执行步骤201。
本申请实施例中，在通话空闲时间窗内进行主耳机切换，避免出现语音通话的过程中进行主耳机切换而丢失重要语音数据的情况，尽量降低主耳机切换对通话的影响。
请参阅图3，图3是本申请实施例公开的另一种主耳机切换方法的流程示意图，如图3所示，该主耳机切换方法包括如下步骤。
301，在移动终端处于通话状态时，移动终端检测是否满足主耳机切换条件。
本申请实施例中的步骤301具体实施可以参见上述图2所示的步骤201，此处不再赘述。
302，若满足主耳机切换条件，移动终端识别语音通话数据是否包含预设关键词。
303，若包含预设关键词，移动终端预测包含预设关键词的一段语音之后的目标时长为通话空闲时间窗。
本申请实施例中，预设关键词包括容易产生语音停顿的词语。比如，“稍等”、“等一下”、“等一等”、“等等”、“想一下”、“想想”、“看看”、“看一下”、“别挂电话”、“hold on”等等。预设关键词还可以包括一句话结束的语气词。比如，“吗”、“呀”、“呢”、“啊”、“啦”、“嘛”、“么”、“喽”、“对吧”、“是吗”、“可以吗”、“行吗”等等。
其中，一段语音指的是一句话对应的语音，一段语音可以由多个连续的语音通话数据组成。比如，每个语音通话数据的持续时长为100ms，一段语音可以包括30个语音通话数据。一般而言，两段语音之间的停顿时长会大于一定时长(比如，200ms)，当检测到连续两个语音通话数据为静音数据时，则认为该段语音结束。如果该段语音中的语音通话数据包括预设关键词，则可以将该段语音结束之后的目标时长为通话空闲时间窗。
本申请实施例可以识别语音通话数据中是否包含预设关键词来确定包含该语音通话数据的一段语音之后的目标时长是否通话空闲时间窗。一般而言，如果语音通话数据中包含 预设关键词，包含该语音通话数据的一段语音之后的停顿时长较长，能够作为通话空闲时间窗进行主耳机切换。本申请实施例可以预测停顿时长较长的时间段作为通话空闲时间窗，以使移动终端处于通话状态时能够有充足的时间在通话空闲时间窗进行主耳机切换，避免出现由于主耳机切换而丢失重要语音数据的情况，从而降低主耳机切换对通话的影响。
304，移动终端在通话空闲时间窗内断开移动终端与第一耳机的通信连接，建立移动终端与第二耳机的通信连接。
其中，若上述语音通话数据不包含预设关键词，则可以继续执行步骤301。
请参阅图4，图4是本申请实施例公开的另一种主耳机切换方法的流程示意图，如图4所示，该主耳机切换方法包括如下步骤。
401，在移动终端处于通话状态时，移动终端检测是否满足主耳机切换条件。
402，若满足主耳机切换条件，移动终端识别语音通话数据是否包含预设关键词。
本申请实施例中的步骤401-402的具体实施可以参见上述图3所示的步骤301-302，此处不再赘述。
403，若包含预设关键词，移动终端确定预设关键词的类型。
404，移动终端根据关键词类型与停顿时长的对应关系确定与预设关键词的类型对应的目标停顿时长。
405，移动终端比较目标停顿时长是否大于参考切换时长。
406，若目标停顿时长大于参考切换时长，移动终端预测包含预设关键词的一段语音之后的目标时长为通话空闲时间窗。
本申请实施例中，预设关键词的类型可以包括一句话结束的语气词，也可以包括容易产生语音停顿的词语。不同的语气词对应的停顿时长可以不相同。语气词与停顿时长的对应关系可以根据历史统计的用户语音数据的语气词与停顿时长的对应关系来确定。举例来说，由于不同的用户在同一语气词之后的停顿时长可以不同，可以统计移动终端的使用者(比如，第一用户)在说出某一语气词之后的平均停顿时长，作为该语气词对应的停顿时长。
参考切换时长，是移动终端执行主耳机切换步骤所需要的时长。参考切换时长可以基于历史统计的切换时长来确定。比如，可以将历史统计的切换时长的平均值作为参考切换时长。如果目标停顿时长大于参考切换时长，表明移动终端在目标停顿时长内可以完成主耳机切换，主耳机切换对语音通话的影响较小；如果目标停顿时长小于参考切换时长，表明移动终端在目标停顿时长内难以完成主耳机切换，主耳机切换对语音通话的影响较大。
本申请实施例可以通过识别语音通话数据中是否包含预设关键字，如果预设关键字对应的停顿时长较长，则将停顿时长较长的时间段作为通话空闲时间窗，以使移动终端处于通话状态时能够有充足的时间在通话空闲时间窗进行主耳机切换，避免出现由于主耳机切换而丢失重要语音数据的情况，从而降低主耳机切换对通话的影响。
其中，若目标停顿时长小于或等于参考切换时长，可以继续执行步骤402。
407，移动终端在通话空闲时间窗内断开移动终端与第一耳机的通信连接，建立移动终端与第二耳机的通信连接。
本申请实施例中的步骤406-407的具体实施可以参见上述图3所示的步骤303-304，此处不再赘述。
本申请实施例中，在通话空闲时间窗内进行主耳机切换，避免出现语音通话的过程中进行主耳机切换而丢失重要语音数据的情况，尽量降低主耳机切换对通话的影响。
上述主要从方法侧执行过程的角度对本申请实施例的方案进行了介绍。可以理解的是，移动终端为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步 骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
本申请实施例可以根据上述方法示例对移动终端进行功能单元的划分，例如，可以对应各个功能划分各个功能单元，也可以将两个或两个以上的功能集成在一个处理单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。需要说明的是，本申请实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
