如图1中所示的移动终端100可以被构造为利用经由帧或分组发送数据的诸如有线和无线通信***以及基于卫星的通信***来操作。
现在将参考图2描述其中根据本发明的移动终端100能够操作的通信***。
这样的通信***可以使用不同的空中接口和/或物理层。例如，由通信***使用的空中接口包括例如频分多址(FDMA，Frequency Division Multiple Access)、时分多址(TDMA，Time Division Multiple Access)、码分多址(CDMA，Code Division Multiple Access)和通用移动通信***(UMTS，Universal Mobile Telecommunications System)(特别地，长期演进(LTE，Long Term Evolution))、全球移动通信***(GSM，Global System for Mobile Communication)等等。作为非限制性示例，下面的描述涉及CDMA通信***，但是这样的教导同样适用于其它类型的***。

基于上述移动终端硬件结构示意图，提出本发明方法各个实施例，具体请参见后续说明。
在介绍本发明方法实施例之前，对前述的对处于通信状态如处于打电话状态的终端来说，很可能终端通过话筒或麦克MIC采集到终端用户不希望采集到的语音数据这一情况结合以下应用场景进行说明，以加深理解。
例如，终端用户1、终端用户2通过各自的终端如终端1、终端2进行通话，终端用户1对于终端用户2提出的某个问题的答案不确定，终端用户1会转身询问其身旁的用户3，此时终端用户1并不希望终端用户2收听到自身与用户3之间的谈话内容，即此时终端用户1不希望话筒或麦克MIC采集到该谈话内容。
实施例一
本发明提供的音频控制方法的第一实施例，应用于一终端中，该终端可以为平板电脑、传统手机、智能手机、电子阅读器等，还可以为智能眼镜、智能手表、智能鞋等穿戴式设备。本发明可选的终端是智能手机。该终端具有音频采集单元和音频输出单元；所述音频采集单元可以为MIC或话筒；所述音频输出单元可以具体为扬声器或听筒。
图3为本发明提供的音频控制方法第一实施例的实现流程示意图；如图3所示，所述方法包括：
步骤301：当终端处于通信状态且通过音频采集单元采集到具有第一音量的音频时，获取第一数据，所述第一数据用于表征所述终端的操作体的第一部位和所述音频采集单元之间的距离、所述操作体的第二部位与所述终端的音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积，其中所述第一区域至少包括所述音频采集单元；
这里，步骤301的执行主体为终端。对于处于通信状态如处于打电话状态的终端来说，音频采集单元对音频进行采集，通常情况下终端将采集到的音频数据控制在默认的音量，以便后续对通信对端的终端进行传输或输出。第一音量即为默认音量，该默认音量通常为终端可输出音量范围的中间值。而在本步骤中在采集到音频并控制该音频的音量为默认音量时，终端并不立即对该音频数据进行传输或输出，而是先对第一数据进行检测，即检测所述终端的操作体的第一部位和音频采集单元之间的距离、所述操作体的第二部位与音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积。
其中，所述操作体可以为处于通信状态的用户；所述第一部位为所述用户的嘴巴；所述第二部位为所述用户的耳朵。所述终端的第一区域被覆盖的面积即为终端中包括语音采集单元的区域被用户的手捂住的面积。
步骤302：判断所述第一数据是否满足第一预定条件；
这里，步骤302的执行主体为终端。终端判断所述第一数据是否满足第一预定条件、具体是判断以下三个子条件中是否有至少一个子条件成立：判断终端用户的嘴巴和音频采集单元之间的距离是否位于第一阈值范围内(子条件一)，判断终端用户的耳朵与音频输出单元之间的距离是否位于第二阈值范围内(子条件二)，和/或判断所述第一区域被覆盖的面积是否位于第三阈值范围内(子条件三)。所述第一阈值范围、第二阈值范围、第三阈值范围可以为范围值也可以为一固定值，可根据实际使用情况而灵活设定。 例如，第一阈值范围为10～20cm，第二阈值范围为5～15cm，第三阈值范围为终端显示屏面积的1/2～1/3；还可以第一阈值范围为20cm，第二阈值范围为8cm，第三阈值范围为终端显示屏面积的1/3。
步骤303：当判断所述第一数据满足第一预定条件时，根据第一数据，对所述第一音量进行调整，得到第二音量，所述第二音量与第一音量不同；
这里，步骤303的执行主体为终端。终端判断为以上三个子条件中至少一个子条件成立时，确定第一数据满足第一预定条件，并根据第一数据，对采集到的音频的音量进行调整，得到第二音量。
步骤304：以所述第二音量对所述音频进行传输，以使与所述终端处于所述通信状态的另一终端能够以所述第二音量进行所述音频的输出。
这里，步骤304的执行主体为终端。终端将采集到的音频的音量调整为第二音量，并传输具有第二音量的音频至对端终端，以使对端终端以第二音量输出该音频。
在一个可选的实施例中，所述终端还包括目标传感器，通过所述目标传感器检测所述操作体的第一部位和音频采集单元之间的距离、所述操作体的第二部位与音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积。在实际应用中，所述目标传感器可以具体为距离传感器、红外传感器或超声波传感器，且这些传感器均可用于检测终端用户的嘴巴与话筒或麦克之间的距离、和/或检测用户的耳朵与听筒或扬声器之间的距离。所述目标传感器还可以为面积传感器，并通过面积传感器、红外传感器或超声波传感器检测终端中包括语音采集单元的区域被用户的手捂住的面积。通过内置的目标传感器来获取第一数据的方法无需对终端本身的硬件结构进行较大的改动即可得到第一数据，该方法简单易性。
在前述方案中，对所述音频采集单元采集到的音频中包括用户语音及环境噪声可以不进行区分，如果要进行区分，可采用以下方案：
在一个可选的实施例中，所述方法还包括：所述音频至少包括第一子音频和第二子音频，所述第一子音频为语音音频，所述第二子音频为环境音音频；
依据预定音频特性，对所述音频中的第一子音频和第二子音频进行分离；
相应的，对所述第一音量进行调整，得到第二音量，包括：
对所述第一子音频的第一音量进行调整，得到第一子音频的第二音量；
相应的，以所述第二音量对所述第一子音频进行传输，或者，以所述第二音量对所述第一子音频以及以所述第一音量对所述第二子音频进行传输。
在实际应用中，对处于通信状态的终端来说，通过音频采集单元所采集到的音频至少包括有所述终端用户产生的语音(第一子音频)及环境噪音(第二子音频)，本方案中可以先对音频采集单元所采集到的音频进行用户产生的语音与环境噪音进行分离。由于人产生的声音的频段为100Hz～10000Hz(赫兹)，噪声频段与人声频率不相同，基于预定的人声的频段，可在采集到的音频中分离出人声与环境噪声。并在后续的对采集到的音频进行音量调整的过程中仅调整人声的音量并仅传输人声的音量至对端终端，当然也可以在传输人声的同时一并传输具有第一音量噪声到对端终端。此处，通过对人声与环境噪声的分离且仅对人声进行音量调整，与前述的不区分用户语音及环境噪声的方案相比，可明显减少终端的处理负担，提升终端处理速度。
本实施例中，当终端处于通信状态且通过音频采集单元采集到具有第一音量的音频时，终端获取终端用户的嘴巴与语音采集单元之间的距离、终端用户的耳朵与语音输出单元之间的距离、和/或终端中包括语音采集单元的区域被用户的手捂住的面积等第一数据信息，当这三个子条件中至少 有一个条件成立时，根据获取到的第一数据，对第一音量进行调整，得到第二音量，并传输具有第二音量的音频至对端终端。如果将传输至对端终端的第二音量视为本地终端的输出音量，本方案实现了对采集到的音频的输出音量的自动控制，无需过多人工参与，可有效提高用户体验，提升终端产品的易用性。
实施例二
本发明提供的音频控制方法的第二实施例，应用于一终端中，该终端可以为平板电脑、传统手机、智能手机、电子阅读器等，还可以为智能眼镜、智能手表、智能鞋等穿戴式设备。本发明可选的终端是智能手机。该终端具有音频采集单元和音频输出单元；所述音频采集单元可以为MIC或话筒；所述音频输出单元可以具体为扬声器或听筒。
图4为本发明提供的音频控制方法第二实施例的实现流程示意图；如图4所示，所述方法包括：
步骤401：当终端处于通信状态且通过音频采集单元采集到具有第一音量的音频时，获取第一数据，所述第一数据用于表征所述终端的操作体的第一部位和所述音频采集单元之间的距离、所述操作体的第二部位与所述终端的音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积，其中所述第一区域至少包括所述音频采集单元；
这里，步骤401的执行主体为终端。对于处于通信状态如处于打电话状态的终端来说，音频采集单元对音频进行采集，通常情况下终端将采集到的音频数据控制在默认的音量，以便后续对通信对端的终端进行传输或输出。第一音量即为默认音量，该默认音量通常为终端可输出音量范围的中间值。而在本步骤中在采集到音频并控制该音频的音量为默认音量时，终端并不立即对该音频数据进行传输或输出，而是先对第一数据进行检测，即检测所述终端的操作体的第一部位和音频采集单元之间的距离、所述操 作体的第二部位与音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积。
其中，所述操作体可以为处于通信状态的用户；所述第一部位为所述用户的嘴巴；所述第二部位为所述用户的耳朵。所述终端的第一区域被覆盖的面积即为终端中包括语音采集单元的区域被用户的手捂住的面积。
步骤402：判断所述第一数据是否满足第一预定条件；
这里，步骤402的执行主体为终端。终端判断所述第一数据是否满足第一预定条件、具体是判断以下三个子条件中是否有至少一个子条件成立：判断终端用户的嘴巴和音频采集单元之间的距离是否位于第一阈值范围内(子条件一)，判断终端用户的耳朵与音频输出单元之间的距离是否位于第二阈值范围内(子条件二)，和/或判断所述第一区域被覆盖的面积是否位于第三阈值范围内(子条件三)。所述第一阈值范围、第二阈值范围、第三阈值范围可以为范围值也可以为一固定值，可根据实际使用情况而灵活设定。例如，第一阈值范围为10～20cm，第二阈值范围为5～15cm，第三阈值范围为终端显示屏面积的1/2～1/3；还可以第一阈值范围为20cm，第二阈值范围为8cm，第三阈值范围为终端显示屏面积的1/3。
步骤403：当判断所述第一数据满足第一预定条件时，调用第一对应关系，在第一对应关系中，查找与所述第一数据对应的音量，如果能够查找到，则确定所查找到的音量为所述第二音量，如果查找不到，则确定处于第一预定范围内的音量且确定处于所述第一预定范围内的任一音量为所述第二音量；
这里，步骤403的执行主体为终端。所述第一对应关系为所述操作体和所述音频采集单元之间的距离与音量之间的对应关系、所述第二部位与所述音频输出单元之间的距离、和/或为所述终端的第一区域被覆盖的面积与音量之间的对应关系。所述第一对应关系为预先设置在终端中的。
所述第一对应关系至少包括子对应关系1、子对应关系2和/或子对应关系3。其中，子对应关系1为用户的嘴巴与话筒或麦克之间的距离(第一距离)与音量的对应关系；子对应关系2为用户的耳朵与听筒或扬声器之间的距离(第二距离)与音量的对应关系；子对应关系3为终端中包括话筒或麦克的区域被用户的手覆盖的面积(第一面积)与音量之间的对应关系。子对应关系1、子对应关系2和/或子对应关系3中的距离与音量之间的取值、终端中被覆盖的面积与音量之间的取值为根据实验或经验而得出。
其中，步骤403可以作为前述的根据第一数据，对所述第一音量进行调整，得到第二音量，所述第二音量与第一音量不同的方案的进一步描述。
步骤404：以所述第二音量对所述音频进行传输，以使与所述终端处于所述通信状态的另一终端能够以所述第二音量进行所述音频的输出。
这里，步骤404的执行主体为终端。终端将采集到的音频的音量调整为第二音量，并传输具有第二音量的音频至对端终端，以使对端终端以第二音量输出该音频。
在实际应用中，对于处于通信中的终端来说，如果终端用户与周围人的谈话内容不想让通信对端用户听到，该终端用户习惯性的动作是将嘴巴尽量远离话筒或麦克、耳朵尽量远离听筒或扬声器和/或用手捂住终端的话筒或麦克，如图6(a)、(b)所示，以使得终端采无法采集到该谈话内容或使得谈话内容的音量尽量小。本实施例中，对能够使得终端无法采集到谈话内容或使得谈话内容的音量尽量小时第一距离、第二距离及第一面积的取值进行测试，并将测试得到的距离或面积数据与在该距离或面积上时无法使对端用户听到的音频音量的大小进行对应记录。例如，测试第一距离为12cm且音频音量为次最小值时无法使对端用户听到谈话内容，那么将12cm、次小值进行对应记录，形成子对应关系1的一条记录；测试第一距离为20cm且音频音量为最小值时无法使对端用户听到谈话内容，那么将 20cm、最小值进行对应记录，形成子对应关系1的一条记录，子对应关系1中的所有记录的集合便形成子对应关系1。子对应关系2、3的形成过程与子对应关系1的形成过程相类似，此处不赘述。
需要说明的是，子对应关系1、2中的第一、二距离与其对应的音量的取值、第一面积与其对应的音量的取值均可以用如图7所示的线性图来表示。例如，以对第一距离进行测试为例，测试完成后可以将第一距离与其对应的音量的取值以函数的形式表示，在图7所示的xoy坐标系中，该函数为y＝ax+b，其中，a、x、b均为正数。当横轴x轴代表嘴巴与话筒或麦克之间距离的取值时，纵轴y轴代表在子对应关系1中的与每一第一距离对应的音量的取值。当然，本领域人员应该理解，如图7所示的线性图仅代表其中一个可选形式而已，并不代表本方案中距离与音量、面积与音量之间的函数关系的所有表现形式。本方案中距离与音量、面积与音量之间的函数关系的表现形式可以为任何能够想到的表现形式。
当终端判断为以上三个子条件中至少一个子条件成立时，终端调用子对应关系1～子对应关系3中的至少一个子对应关系，如果终端在采集到所述音频数据时仅确认用户的嘴巴远离了话筒或麦克即通过距离传感器检测到用户的嘴巴与话筒或麦克之间的距离达到了12cm，位于第一阈值范围内，而用户的耳朵并没有远离听筒或扬声器且用户的手也没有捂住话筒或麦克，那么仅需调用子对应关系1，并判断在子对应关系1中是否能够查找到与第一距离(12cm)对应的音量，因为子对应关系1存在有12cm、音量次小值之间的对应记录，所以能够查找到与第一距离(12cm)对应的音量且该音量为音量次小值，那么终端调整在通信过程中采集到的用户输入的音频的音量为音量次小值，并将音量次小值作为对第一音量进行调整后的第二音量，并传输具有第二音量的音频至对端终端。如果在子对应关系1中查找不到与第一距离(12cm)对应的音量，则将读取处于第一预定范围内 的其中一个音量并将其为第二音量并传输具有第二音量的音频至对端终端。对端终端以第二音量输出该音频，由于第二音量本身是无法使得对方听到的音量所以对端终端无法收听到该音频。
需要指出的是，由于终端可采用三种语音输出模式与对端终端进行通信：听筒模式、免提模式、耳机模式，在本申请中预先为每种模式设置一个对应的音频通道，通过该音频通道传输音频至对端终端。以终端为以听筒模式与对端终端进行通信为例，当在子对应关系1中查找到与第一距离(12cm)对应的音量并将音频采集单元采集到的音频的音量调整为与第一距离(12cm)对应的音量的过程实际上就是调整与听筒模式对应的音频通道的增益的过程，对与听筒模式对应的音频通道进行增益的增加，以使得输出至对端用户的音量为与第一距离(12cm)对应的音量。
其中，预先设置第一预定范围内的每个音量均为使得对端用户无法收听到音频的音量，如设置第一预定范围为0dB(无声音状态)。
本领域人员应该而知，前述方案为对在不区分用户语音及环境噪声这一情况下如何对音频进行音量调整过程的描述，如果需要对人声与环境噪声的分离，关于分离情况下对音频、具体人声进行音量调整的方案请结合本实施例及前述实施例一中的相关内容而进行理解，此处不再赘述。
前述方案中，当终端处于通信状态且通过音频采集单元采集到具有第一音量的音频时，终端获取终端用户的嘴巴与语音采集单元之间的距离、终端用户的耳朵与语音输出单元之间的距离、和/或终端中包括语音采集单元的区域被用户的手捂住的面积等第一数据信息，当这三个子条件中至少有一个条件成立时，调用子对应关系1～3中的任意一个，并查找所调用的子对应关系中与第一数据对应的音量的取值，如果能够查找到将该取值作为第二音量并传输具有第二音量的所述音频至对端终端。如果将传输至对端终端的第二音量视为本地终端的输出音量，本方案实现了对采集到的音 频的输出音量的自动控制，无需过多人工参与，可有效提高用户体验，提升终端产品的易用性。

图5为本发明提供的音频控制方法第三实施例的实现流程示意图；如图5所示，所述方法包括：
步骤501：当终端处于通信状态且通过音频采集单元采集到具有第一音量的音频时，获取第一数据，所述第一数据用于表征所述终端的操作体的第一部位和所述音频采集单元之间的距离、所述操作体的第二部位与所述终端的音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积，其中所述第一区域至少包括所述音频采集单元；
这里，步骤501的执行主体为终端。对于处于通信状态如处于打电话状态的终端来说，音频采集单元对音频进行采集，通常情况下终端将采集到的音频数据控制在默认的音量，以便后续对通信对端的终端进行传输或输出。第一音量即为默认音量，该默认音量通常为终端可输出音量范围的中间值。而在本步骤中在采集到音量为默认音量的音频数据时，终端并不立即对该音频数据进行传输或输出，而是先对第一数据进行检测，即检测所述终端的操作体的第一部位和音频采集单元之间的距离、所述操作体的第二部位与音频输出单元之间的距离、和/或所述终端的第一区域被覆盖的面积。
其中，所述操作体可以为处于通信状态的用户；所述第一部位为所述 用户的嘴巴；所述第二部位为所述用户的耳朵。所述终端的第一区域被覆盖的面积即为终端中包括语音采集单元的区域被用户的手捂住的面积。
步骤502：判断所述第一数据是否满足第一预定条件；
这里，步骤502的执行主体为终端。终端判断所述第一数据是否满足第一预定条件、具体是判断以下三个子条件中是否有至少一个子条件成立：判断终端用户的嘴巴和音频采集单元之间的距离是否位于第一阈值范围内(子条件一)，判断终端用户的耳朵与音频输出单元之间的距离是否位于第二阈值范围内(子条件二)，和/或判断所述第一区域被覆盖的面积是否位于第三阈值范围内(子条件三)。所述第一阈值范围、第二阈值范围、第三阈值范围可以为范围值也可以为一固定值，可根据实际使用情况而灵活设定。例如，第一阈值范围为10～20cm，第二阈值范围为5～15cm，第三阈值范围为终端显示屏面积的1/2～1/3；还可以第一阈值范围为20cm，第二阈值范围为8cm，第三阈值范围为终端显示屏面积的1/3。
步骤503：当判断所述第一数据满足第一预定条件时，控制所述音频的音量减少至处于第二预定范围内的音量，并确定所减少至的音量为所述第二音量；
这里，预先设置第二预定范围内的每个音量均为使得对端用户无法收听到音频的音量，如设置第二预定范围为0dB(无声音状态)～0.001dB。
步骤504：以所述第二音量对所述音频进行传输，以使与所述终端处于所述通信状态的另一终端能够以所述第二音量进行所述音频的输出。
这里，步骤504的执行主体为终端。终端将采集到的音频的音量调整为第二音量，并传输具有第二音量的音频至对端终端，以使对端终端以第二音量输出该音频。
在实际应用中，只要终端判断为以上三个子条件中至少一个子条件成立就可以确认终端用户有不希望对端用户收听到其与周围人交谈内容的需 求，那么终端就直接从预先设置好的第二预定范围中读取其中任意一个音量的取值，并将通过音频采集单元所采集到的音频从第一音量调整为所读取的音量如将所采集到的音频数据的音量直接调整为0dB，终端将所读取的音量作为第二音量。对端终端以第二音量输出该音频，由于第二音量本身是无法使得对方听到的音量所以对端终端无法收听到该音频。
本领域人员应该而知，前述方案为对在不区分用户语音及环境噪声这一情况下如何对音频进行音量调整过程的描述，如果需要对人声与环境噪声的分离，关于分离情况下对音频、具体人声进行音量调整的方案请结合本实施例及前述实施例一中的相关内容而进行理解，此处不再赘述。
前述方案中，当终端处于通信状态且通过音频采集单元采集到具有第一音量的音频时，终端获取终端用户的嘴巴与语音采集单元之间的距离、终端用户的耳朵与语音输出单元之间的距离、和/或终端中包括语音采集单元的区域被用户的手捂住的面积等信息，当这三个子条件中至少有一个条件成立时，终端直接从预先设置好的第二预定范围中读取其中任意一个音量作为对该音频的调整后音量。由于第二音量本身是无法使得对方听到的音量所以对端终端无法收听到该音频，所以对端用户无法收听到该音频。如果将传输至对端终端的第二音量视为本地终端的输出音量，本方案实现了对采集到的音频的输出音量的自动控制，无需过多人工参与，可有效提高用户体验，提升终端产品的易用性。
