Description

语音通路的检测方法、装置和终端 技术领域
本发明实施例涉及通信领域，尤其涉及语音通路的检测方法、装置和终端。
背景技术
当前，用户经常会使用手机进行通话。随着手机尺寸的逐渐增大，用户在通话过程中，通常会用手指托一下手机的下延。由于手机上的麦克风通常设置于手机的下延，并且手机上的麦克风的开孔通常很小，因此用户的手指可能会遮挡住麦克风。当麦克风的开孔被遮挡时，即语音通路被堵塞时，用户说话的声音并未传入麦克风，从而造成对方无法听到用户的声音。
为了避免发生上述语音通路被堵塞的情况，现有技术中有些厂家会在手机的麦克风部分开设多个开孔，以防止用户在通话过程中用手指遮挡麦克风。但是这种方式会增加麦克风进尘的风险，并且可能会影响扬声器等器件的工作，形成干扰。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
当本发明实施例提及“第一”、“第二”等序数词时，除非根据上下文其确实表达顺序之意，应当理解为仅仅起区分的作用。
图1为本发明实施例提供的一种检测通信终端的语音通路的方法流程图。该方法的执行主体为通信终端，通信终端可以但不限于为手机等能够进行语音通信的终端。本发明实施例中主要以手机为例来进行说明。通信终端包括主麦克风和副麦克风，主麦克风和副麦克风在通信终端上的位置距离较远，通常地，用户在手持通信终端进行语音通话时，主麦克风位于通信终端的下部，副麦克风位于通信终端的上部，容易出现用户手指遮挡主麦克风，从而造成语音通路被堵塞的情况。为了识别这种情况的发生，该方法包括：
步骤101，当通信终端处于手持通话状态时，获取主麦克风获取的第一声音的音量值与副麦克风获取的第二声音的音量值。
本发明实施例中，通信终端具有主麦克风和副麦克风，主麦克风用于接收用户发出的语音信号，副麦克风用于接收通话环境中的噪音信号，通信终端可以根据副麦克风接收的信号，对主麦克风接收的信号进行降噪处理。
图2为本发明实施例提供的麦克风的工作示例示意图。参照图2，本发明实施例中，可以将通信终端称为手持设备，在通话双方的一方用户使用手持设备进行通话的过程中，手持设备的主麦克风(简称为主mic)和副麦克风(简称为副mic)获取声音信号，由手持设备对获取的声音信号进行录音并编码， 通过网络传输语音数据给对方手持设备，通话双方的对方用户收听由该对方手持设备的听筒等器件发出的声音。
在一个典型的应用场景中，在用户使用手机通话时，由于用户正常的通话习惯是对着手机下部说话，因此将位于手机下部的麦克风称为主麦克风，将位于手机上部的麦克风称为副麦克风，副麦克风主要用于接收环境声音，手机可以利用副麦克风接收到的环境声音，来对主麦克风接收到的声音信号进行降噪处理。
音量值是用来衡量声音强弱的参数，可以根据声音的强度计算一段时间内的音量值。
对应于人的听力的特征描述，可以将音量值划分为如下几个区间范围：a：0－20分贝，很静、几乎感觉不到；b：20－40分贝，安静、犹如轻声絮语；c：40－60分贝，一般、普通室内谈话；d：60－70分贝，吵闹、有损神经，已经超出安全音量；e：超出70分贝以上，定义为受损音量。其中，通话音量通常处于上述b或c区间范围，约40分贝。
本发明实施例中，为了更加准确地反映一段时间内的声音强弱，避免后续发生误判，上述第一声音的音量值为预设时间段内主麦克风获取的第一声音的平均音量值；上述第二声音的音量值为预设时间段内副麦克风获取的第二声音的平均音量值。
步骤102，根据第一声音的音量值与第二声音的音量值的差值，确定语音通路是否被堵塞。
由于主麦克风通常位于手机下部，副麦克风通常位于手机上部，用户正常的通话习惯是对着手机下部说话，因此副麦克风接收到声音的音量值会小于主麦克风接收到声音的音量值。也就是说，正常通话时，主麦克风接收的第一声音的音量值与副麦克风接收的第二声音的音量值的差值应当属于一个区间范围。而当语音通路被堵塞时，主麦克风接收的第一声音的音量值与副麦克风接收的第二声音的音量值的差值应当属于另一个区间范围。通常情况 下，语音通路被堵塞指的是主mic被堵塞了，所以当被堵塞之后，主mic接收的声音的音量值与副mic接收的声音的音量值之间的差值较小。
本发明实施例中，可以设定第一阈值，当第一声音的音量值与第二声音的音量值的差值小于或等于第一阈值时，确定语音通路被堵塞。上述第一阈值可以设定为0，也可以根据实际的精度需求设定为其他数值，例如，5分贝或-5分贝。
由于当用户使用通信终端进行语音通话的过程中，可能会出现停顿，也就是说，可能出现主麦克风和副麦克风均接收不到语音信号的时间段，此时单纯利用第一声音的音量值与第二声音的音量值的差值来确定语音通路是否被堵塞，有可能出现误判，因此需要判断副麦克风是否能够接收到声音信号并且接收到的声音信号的音量值符合正常通话的情况，而不是处于停顿。
本发明实施例中，为了提高检测的准确度，可以结合第一声音的音量值与第二声音的音量值的差值，以及第二声音的音量值，共同来判定语音通路是否被堵塞。具体地，当第一声音的音量值与第二声音的音量值的差值小于或等于第一阈值，且第二声音的音量值大于或等于第二阈值时，确定语音通路被堵塞。其中，可以根据实际的精度需求来设定上述第二阈值，例如，设定第二阈值为20分贝。
本发明实施例中，当确定出语音通路被堵塞时，可以指示通信终端发出报警信号，该报警信号用于提示用户语音通路被堵塞。该报警信号的具体形式本发明实施例不做具体限定，例如，可以为声音信号，也可以为振动信号，或者光信号等。为避免误判，可以循环多次执行步骤101和步骤102，当多次执行的结果均为确定语音通路被堵塞时，再向用户发出报警信号，以使用户改变手持通话时的手势，以避免语音通路被堵塞。
此外，由于本发明实施例所提供的方法是针对于用户手势不当所引起的语音通路被堵塞，因此在步骤101之前，可以先确定通信终端是否处于手持通话状态，具体地，可以先获取通信终端的通话模式参数的参数值；根据通 话模式参数的参数值，确定通信终端处于手持通话状态。
由于有些通信终端在手持通话状态和免提通话状态时，使用的语音输出设备不同，因此还可以获取通信终端使用的语音输出设备的类型，根据获取的通信终端使用的语音输出设备的类型，确定通信终端处于手持通话状态。
此外，当主麦克风或者副麦克风出现故障时，也会引起误判，因此在步骤101之前，可以先检测主麦克风和副麦克风是否均正常工作，具体地，获取主麦克风和副麦克风的工作状态参数的参数值；根据工作状态参数的参数值，确定主麦克风和副麦克风均正常工作。
当手机存在多个麦克风时，例如，一个主麦克风、两个副麦克风，若需判断主麦克风是否被用户的手指堵住，可以参考任意一个副麦克风接收声音的音量值，也可以参考两个副麦克风接收声音的音量值进行综合判断。
具体地，当主麦克风接收声音的音量值与多个副麦克风中的每个副麦克风接收声音的音量值的差值均小于或等于第一阈值时，确定语音通路被堵塞。
或者，当主麦克风接收声音的音量值与多个副麦克风中的每个副麦克风接收声音的音量值的差值均小于或等于第一阈值，且多个副麦克风中的每个副麦克风接收声音的音量值的差值均大于或等于第二阈值时，确定语音通路被堵塞。
或者，为多个副麦克风中的每个副麦克风分别设置权重，将每个副麦克风接收声音的音量值乘以相应的权重再求和，结果作为多个副麦克风接收声音的综合音量值，当主麦克风接收声音的音量值与多个副麦克风接收声音的综合音量值的差值小于或等于第一阈值时，确定语音通路被堵塞。
或者，为多个副麦克风中的每个副麦克风分别设置权重，将每个副麦克风接收声音的音量值乘以相应的权重再求和，结果作为多个副麦克风接收声音的综合音量值，当主麦克风接收声音的音量值与多个副麦克风接收声音的综合音量值的差值小于或等于第一阈值，且多个副麦克风中的每个副麦克风接收声音的音量值的差值均大于或等于第二阈值时，确定语音通路被堵塞。
具体地实现方式有很多，在此不做赘述。
本发明实施例提供了一种检测通信终端的语音通路的方法，通信终端包括主麦克风和副麦克风，当通信终端处于手持通话状态时，获取主麦克风获取的第一声音的音量值与副麦克风获取的第二声音的音量值；根据第一声音的音量值与第二声音的音量值的差值，确定语音通路是否被堵塞，从而可以在检测出语音通路被堵塞时，提示用户改变手势，这种方式简单、有效，不会造成其他的不良影响。
下面以通信终端为手机为例，通过一个具体的实施例对本发明提供的检测通信终端的语音通路的方法进行说明。
图3为本发明实施例提供的另一种检测通信终端的语音通路的方法流程图。该方法包括如下：
步骤301，当启动一个通话时，手机获取该手机的mic设备信息。
其中，mic为麦克风的简写，mic设备信息包括主麦克风的器件信息和副麦克风的器件信息。
步骤302，手机判断该通话的通话类型是否属于手持通话。
当判断结果为属于手持通话时，执行步骤303；否则，执行步骤308。
步骤303，手机判断主mic和副mic是否正常工作。
当判断结果为主mic和副mic均正常工作时，执行步骤304；否则，当判断结果为主mic和副mic中至少有一个非正常工作时，执行步骤308。
步骤304，手机确定主mic和副mic在预设时间段内接收的声音的音量值。
其中，音量值也可称为音量强度，上述预设时间段可以设定为N秒，N的取值为正整数，例如，N取值为5，上述预设时间段设定为5秒。
步骤305，手机判断副mic的音量值是否大于主mic的音量值。
当判断结果为副mic的音量值大于主mic的音量值时，执行步骤306；否则，当判断结果为副mic的音量值小于或等于主mic的音量值时，执行步骤308。主mic的音量值指的是主mic接收的声音的音量值。副mic的音量值指 的是副mic接收的声音的音量值。
需要说明的是，本实施例的判断条件为副mic的音量值是否大于主mic的音量值。该判断条件仅是一个具体的例子。在具体实现过程中，判断条件可以有多种。判断条件例如还可以为：主mic的音量值与副mic的音量值的差值是否小于某一预设值。
步骤306，手机判断副mic的音量值是否大于20分贝(DB)。
当判断结果为副mic的音量值大于20分贝时，执行步骤307；否则，当判断结果为副mic的音量值小于或等于20分贝时，执行步骤308。
其中，设定阈值为20分贝仅为举例说明，并不用于对本发明的限定。
步骤307，手机判定mic被堵住了。
也就是说，确定语音通路被堵塞。一般而言，语音通路被堵塞指的是主mic被堵住了。
步骤308，结束该处理流程。
本发明实施例中，在用户通话过程中，先检测用户使用的手机的语音输入器件，当用户使用手机底部的mic作为语音输入器件时，判定该通话为手持通话。然后判断主副mic是否正常工作，当判断出手机包含主mic和副mic，主副mic都在使用中且正常工作时，顺序执行该方法的后续流程，否则当主mic和副mic中的至少一个发生异常没有启动(open)成功时，可能硬件出现问题，为防止误判，结束该处理流程。在该方法的后续流程中，获取指定时间内(Ns)主mic与副mic的音量值，当主mic的音量值小于或等于副mic的音量值的时候，判断副mic的音量是否大于20分贝，当判断出副mic的音量大于20分贝时，说明处于正常通话过程中，此时判断用户因手指按压引起单通，由于本发明实施例中，经过多项判决，因此检测结果准确度高，可以最大限度地避免误判。
优选地，为了进一步提高判决的准确度，可以多次执行本发明实施例的方法，当多次执行的结果均显示语音通路被堵塞，或者，多次执行的结果中 显示语音通路被堵塞的次数超过预设次数时，再确认语音通路被堵塞的最终判决结果，并向用户发出报警信号。

重力传感器(gravity sensor)560，可以检测手机在各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等。
手机500还可以包括其它传感器，比如光传感器。具体地，光传感器可包括环境光传感器及接近光传感器。其中，环境光传感器可根据环境光线的明暗来调节显示面板551的亮度；接近光传感器可以检测是否有物体靠近或接触手机，可在手机500移动到耳边时，关闭显示面板551和/或背光。手机500还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
音频电路570、扬声器573、主麦克风571、副麦克风572可提供用户与手机500之间的音频接口。音频电路570可将接收到的音频数据转换后的电 信号，传输到扬声器573，由扬声器573转换为声音信号输出；另一方面，主麦克风571、副麦克风572将收集的声音信号转换为电信号，由音频电路570接收后转换为音频数据，再将音频数据输出至RF电路530以发送给比如另一手机，或者将音频数据输出至存储器510以便进一步处理，其中，主麦克风571用于接收用户发出的语音信号，副麦克风572用于接收通话环境中的噪音信号，手机500可以根据副麦克风572接收的信号，对主麦克风571接收的信号进行降噪处理。
处理器520是手机500的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器510内的软件程序和/或模块，以及调用存储在存储器510内的数据，执行手机500的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器520可包括一个或多个处理单元；优选的，处理器520可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器520中。
手机500还包括给各个部件供电的电源580(比如电池)，优选的，电源可以通过电源管理系统与处理器520逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
尽管未示出，手机500还可以包括WiFi(wireless fidelity，无线保真)模块、蓝牙模块等，在此不再赘述。
