为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的一种呼叫控制处理方法的流程示意图；
图2是本发明实施例提供的一种移动终端的结构示意图。
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清
楚、完整地描述，显然，所描述的实施例仅仅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作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。
参见图1，为本发明实施例提供的一种呼叫控制处理方法的流程示意图，在本发明实施例中，所述呼叫控制处理方法包括：
S101、确定当前呼叫号码是否为陌生号码，若是，则进入虚拟人工接听模式，若否，则进入正常接听模式；
具体而言，移动终端接收到呼叫后，操作单元获取该呼叫对应的号码，并将该号码与存储单元中的号码数据库进行匹配处理，该号码数据库可为但不限于移动终端中的通信录号码数据库或者移动终端的历史通话和短信记录对应号码数据库。其中该号码匹配处理可采用顺序遍历查询或者二叉树遍历查询的方式进行，该号码数据库中的号码可按照录入时间顺序或者数值大小顺序的形式排布。当匹配单元在该号码数据中查询到当前呼叫的号码时，即该当前呼叫的号码具有正常接入权限，则向该操作单元反馈关于当前呼叫号码正常的指令，当匹配单元在该号码数据中无法查询到当前呼叫的号码时，即该当前呼叫的号码为陌生号码，其不具有正常接入权限，则向该操作单元反馈关于当前呼叫号码异常的指令。
当该操作单元接收到关于当前呼叫号码正常的指令时，该操作单元向接听单元发送允许用户接听的指令，此时接听单元将当前呼叫转接到正常接听模式中，该正常接听模式允许用户进行人工接听或者挂断等操作；当该操作单元接收到关于当前呼叫号码异常的指令时，该操作单元向该接听单元发送禁止用户接听的指令，此时该操作单元切断当前呼叫与该正常接听模式的链路，该接听单元将当前呼叫转接至虚拟人工接听模式中，该虚拟人工接听模式可以是用户预先录制的具有不同通话场景的通话模式，该通话模式为具有多段关于用户的语音通话内容的应答数据库，该接听单元能够根据当前呼叫通话的内容从该应当数据库中选择相应的语音通话内容与呼叫方进行互动。在该虚拟人工接听模式中，该接听单元对呼叫方的通话进行关键词的语音识别，从而根据该语音识别的结果在该应答数据库中进行语音通话内容的选择。
S102、在虚拟人工接听模式中，获取呼叫方的声音信息，并提取声音信息
中的声纹信息；
具体而言，该接听单元还能够对呼叫方得通话声音进行采样录音，该采样录音可以是关于呼叫方的完整通话录音或者是关于呼叫方的片段通话录音，并将该采样录音内容传送到分析单元中。该分析单元能够提取该采样录音内容中的声纹信息，由于每个人各自的声带、鼻腔、口腔、舌头、唇和肺部等相关发声器官的结构并不相同，以及每个人的说话习惯迥异，这导致每个人的说话声音存在独特的特点，并且该特点可从声谱图中分辨和提取出来，从而以声纹的形式作为每个人声音的独特标志。利用声纹这一特点，在仅仅与对方通话的情况下也能分别出对方的身份，这种方式也就做声纹识别。该声纹识别可以从声学特征或者用辞特征等方面进行识别，其中声学特征可包括但不限于频谱、倒频谱、共振峰或者基音等，而用辞特征可包括但不限于音素或者语调等。
实际上，呼叫方可能并不是真实存在的人进行通话，而是通过数字音频合成的方式产生的，由于数字音频合成的声音的声纹信息通常都比较平稳，其起伏变化并不明显当接听单元确定当前呼叫方的通话是通过数字音频合成来形成的，该接听单元也可以向该操作单元反馈关于当前呼叫通话异常的指令，此时该操作单元能够基于该指令中止当前呼叫通话的进行。
S103、将提取的声纹信息与声纹信息库中的声纹特征数据进行匹配处理，若匹配处理结果为肯定，则切断当前通话，否则，将当前通话切换至正常接听模式；
具体而言，该接听单元将从采样录音中提取的声纹信息传送至该匹配单元中，该匹配单元将接收到的声纹信息与该存储单元中声纹信息库的声纹特征数据进行匹配处理。该匹配处理的方式包括模板匹配方法、最相邻方法、神经网络法、马尔可夫模型法或者多项式分类法等，其中，该模板匹配法是利用动态时间弯折以对准训练和测试特征序列，其主要针对声纹信息中的固定用辞进行的；该最相邻方法是识别声纹信息中每个特征矢量中与训练矢量最相近的N个特征矢量，其运算量通常较大；该神经网络法是采用多层径向基函数进行显示训练来区分采样录音中的说话目标；该马尔可夫模型法是通常采用高斯混合模型来进行声纹信息的分析，其具有较好的效果；该多项式分类法是利用多项式模型来进行声纹信息的计算，其计算精度较高，但是计算量大且计算速度较
慢。本领域的技术人员可根据实际需要来选择上述匹配处理方法中的一种或者多种，从而实现提高声纹信号匹配计算速度和降低计算过程所需内存的效果。
当该匹配单元从该声纹信息库中识别出该提取的声纹信息，则表明当前呼叫通话与移动终端某一历史骚扰通话皆出自同一人，此时该匹配单元向该操作单元反馈关于当前呼叫通话异常的指令，该操作单元基于该指令中止和切断当前通话；当该匹配单元不能从该声纹信息库中识别出该提取的声纹信息，此时该匹配单元向该操作单元反馈关于当前呼叫通话正常的指令，该操作单元基于该指令将当前呼叫通话切换至正常接听模式中。
此外，当用户在该正常接听模式中辨别出当前呼叫通话为骚扰电话时，用户还可对当前呼叫通话的号码标识为骚扰号码，并对来自该骚扰号码的呼叫进行屏蔽，同时移动终端还将当前呼叫通话提取的声纹信息收录到该声纹信息库中，以实现该声纹信息库的数据更新。
从上述实施例可以看出，该呼叫控制处理方法能够对移动终端设置虚拟人工接听模式和正常接听模式这两种不同的接听方式，该虚拟人工接听模式能够避免用户因接听来自陌生号码的首次呼叫而造成时间浪费和隐私泄露，同时该虚拟人工接听模式还能够对呼叫方的通话声音进行采样并提取其中的声纹信息，以实现当前呼叫通话的声纹信息识别，从而判断该呼叫是否与移动终端接收的历史骚扰电话来自同一人，可见该呼叫控制处理方法能够有效避免用户受到陌生来电的骚扰，并且还能提高移动终端的通信安全性。
参见图2，为本发明实施例提供的一种移动终端的结构示意图，在本发明实施例中，该移动终端包括操作单元、存储单元、接听单元和匹配单元。
其中，该存储单元保持有号码数据库和声纹信息库，该号码数据库可为但不限于移动终端中的通信录号码数据库或者移动终端的历史通话和短信记录对应号码数据库；该声纹信息库中收录中移动终端历史接收到的骚扰电话中的声纹信息，并能该声纹信息库能够对实时对其中声纹数据进行更新。
该接听单元能够实施虚拟人工接听模式和正常接听模式的切换，其中该虚拟人工接听模式可以是用户预先录制的具有不同通话场景的通话模式，该通话模式为具有多段关于用户的语音通话内容的应答数据库，该接听单元能够根据当前呼叫通话的内容从该应当数据库中选择相应的语音通话内容与呼叫方进
行互动。在该虚拟人工接听模式中，该接听单元对呼叫方的通话进行关键词的语音识别，从而根据该语音识别的结果在该应答数据库中进行语音通话内容的选择；该正常接听模式则是允许移动终端的用户直接与呼叫方进行通话。
该匹配单元能够将移动终端当前呼叫的号码与该号码数据库进行匹配处理，以及将该接听单元提取的声纹信息与该声纹信息库进行匹配处理。其中，当前呼叫的号码与该号码数据库进行匹配处理可采用顺序遍历查询或者二叉树遍历查询的方式进行；该提取的声纹信息与该声纹信息库进行匹配处理可采用模板匹配方法、最相邻方法、神经网络法、马尔可夫模型法或者多项式分类法等方法进行。
该操作单元用于控制存储单元、接听单元和匹配单元的工作，比如根据该匹配单元关于当前呼叫的号码与该号码数据库的匹配处理结果或者关于该提取的声纹信息与该声纹信息库的匹配处理结果来控制接听单元在该虚拟人工接听模式和正常接听模式之间的切换。该移动终端可以用于执行图1所示的呼叫控制处理方法。关于本实施例涉及的术语的含义以及举例，可以参考图1对应的实施例。此处不再赘述。
从上述实施例可以看出，该移动终端能够实现虚拟人工接听模式和正常接听模式这两种不同接听方式的切换，该虚拟人工接听模式能够避免用户因接听来自陌生号码的首次呼叫而造成时间浪费和隐私泄露，同时该虚拟人工接听模式还能够对呼叫方的通话声音进行采样并提取其中的声纹信息，以实现当前呼叫通话的声纹信息识别，从而判断该呼叫是否与移动终端接收的历史骚扰电话来自同一人，因此该移动终端具有较高的通信安全性。

- 根据权利要求1所述的方法，其特征在于，在S101中，在进入所述虚拟人工接听模式后，能够通过设定不同的通话场景来实现与所述呼叫方的虚拟通话互动；其中所述虚拟人工接听模式能够从所述呼叫方的通话中识别语音关键词，以此在应答数据库中选择预设的语音通话内容进行所述虚拟通话互动。
- 根据权利要求1所述的方法，其特征在于，在S102中，当所述提取的声纹信息被识别为来自数字音频合成的声音后，反馈所述当前通话异常的指令，并中止切断所述当前通话。
- 根据权利要求1所述的方法，其特征在于，在S103中，所述提取的声纹信息与声纹信息库中的声纹特征数据进行匹 配处理通过模板匹配方法、最相邻方法、神经网络法、马尔可夫模型法和多项式分类法中的一种或多种来实现。
- 一种移动终端，所述移动终端包括：操作单元、存储单元、接听单元和匹配单元，其特征在于：所述存储单元保持有号码数据库和声纹信息库，所述号码数据库用于辨别当前呼叫的号码是否为陌生号码，所述声纹信息库用于辨别当前呼叫方是否为历史禁止接听的呼叫方；所述接听单元能够实施虚拟人工接听模式和正常接听模式的切换，以及对所述呼叫方进行声纹信息的去提取；所述匹配单元能够将所述当前呼叫的号码与所述号码数据库进行匹配处理，以及将所述接听单元提取的声纹信息与所述声纹信息库进行匹配处理；所述操作单元用于控制所述存储单元、所述接听单元和所述匹配单元的工作。
- 根据权利要求6所述的移动终端，其特征在于，所述接听单元在所述虚拟人工接听模式下，能够从所述呼叫方的通话中识别语音关键词，以此在应答数据库中选择预设的语音通话内容进行不同的通话场景的虚拟通话互动。
- 根据权利要求6所述的移动终端，其特征在于，所述接听单元能够向所述操作单元反馈关于当前呼叫正常或者异常的指令；所述操作单元基于所述指令控制所述接听单元在所述虚拟人工接听模式和所述正常接听模式之间进行切换。
- 根据权利要求6所述的移动终端，其特征在于，所述接听单元还能够识别所述提取的声纹信息是否来自数字音频合成的声音。
- 根据权利要求6所述的移动终端，其特征在于，所述匹配单元通过模板匹配方法、最相邻方法、神经网络法、马尔可夫模型法和多项式分类法中的一种或多种来实现将所述提取的声纹信息与所述声纹信息库进行匹配处理。
