附图说明
为了更清楚地说明本发明具体实施方式或现有技术中的技术方案，下面将对具体实施方式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，下面描述中的附图是本发明的一些实施方式，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2是基于车载娱乐系统的车辆内外通话系统架构图。
图3是本发明实施例的系统架构图。
图4是车辆及其外部音频采集设备的结构示意图。
图5是本发明实施例的原理图。

图7是电子设备的系统架构图。
具体实施方式
下面将结合附图对本发明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。
如图1所示，基于车载娱乐系统的车辆内外通话方法流程具体包括车外通话场景和车内通话场景，其中：
车外通话场景具体为：
利用车辆的外部音频采集设备，采集车辆的外部音频信号；
将外部音频信号传递至车内并进行解码和降噪，提取外部音频信号中的外部人声；
对外部人声进行音频效果处理，输出到整车功放，通过车内扬声器进行播放；
车内通话场景具体为：
利用车辆的内部音频采集设备，采集车辆的内部音频信号；
将内部音频信号进行解码和降噪，提取内部音频信号中的内部人声；
对内部人声进行音频效果处理，输出到整车功放，通过车外扬声器进行播放。
具体的，对所述内部人声进行音频效果处理，具体为：通过信息娱乐控制器中的数字处理芯片对人声进行音频效果处理。
具体的对内部人声进行音频效果处理，输出到整车功放，通过车外扬声器进行播放，具体为：通过信息娱乐控制器中的数字处理芯片对人声进行音频效果处理，并通过汽车音频总线接口(A2B)输出到整车功放，通过车外扬声器进行播放。
具体的，外部音频采集设备为车外麦克风，内部音频采集设备为车内麦克风。
具体的，将所述外部音频信号传递至车内并进行解码和降噪，具体为：将所述外部音频信号传递到车辆内部的信息娱乐控制器，提取外部音频信号中的外部人声。
作为进一步的改进，本发明实施例还考虑到在车内并进行解码和降噪时可能会遇到的声音输出抢占问题：车辆内部声音输出方式为抢占式输出，例如通过收音机等媒体音和蓝牙电话等通话音输出时为单一焦点抢占模式，在单一焦点抢占模式中为新接入的音频替代当前音频进行播放，且车辆行驶时只能有一个音频进行播放，且通常为短暂性的接入音频，那么在进行车内外通话时会遇到用新音频替代当前音频播放的情况，降低了用户在进行车内外通话时的体验感。
具体的，
若检测到车辆进行内通话时目标音频的抢占输出事件，则获取目标音频的优先级；
检测目标音频的优先级是否大于当前播放音频的优先级，如果检测目标音频的优先级大于当前播放音频的优先级，则检测当前播放音频的所属类型是否为可混音类；
若当前播放音频为可混音类，则将当前播放音频和目标音频进行混音操作得到混音音频，输出混音音频。
示例性的，确定车辆内外通话信息，并根据当前的车辆内外通话信息，确定当前播放音频待输出的车内播放音量和车辆内外通话信息的播放音量；
控制当前播放音频处于第一播放音量，并控制目标音频处于第二播放音量，用于得到混音音频；
按照第一播放音量在第一播放通道内输出当前播放音频，且按照第二播放音量在第二播放通道内输出目标音频。
本领域技术人员能够根据生活常识、驾驶常识以及本领域的普通技术知识，确定当前播放音频是否为可混音类型，若不为可混音类，则检测当前播放音频的所属类型是否为可暂停类；若为可暂停类，则控制当前播放音频的播放状态为暂停；并将目标音频作为行驶车辆的输出音频。
对于上述实施例公开的方法步骤，出于简单描述的目的将方法步骤表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明实施例并不受所描述的动作顺序的限制，因为依据本发明实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本发明实施例所必须的。
如图2所示，基于车载娱乐系统的车辆内外通话系统具体包括：
车辆外部音频信号采集模块，用于利用车辆的外部音频采集设备，采集车辆的外部音频信号；
车辆外部音频信号解码降噪模块，用于将所述外部音频信号传递至车内并进行解码和降噪，提取外部音频信号中的外部人声；
车辆外部音频信号音效处理模块，用于对外部人声进行音频效果处理，输出到整车功放，
车辆外部音频信号播放模块，用于通过车内扬声器播放经过音频处理的车辆外部音频信号；
车辆内部音频信号采集模块，利用车辆的内部音频采集设备，采集车辆的内部音频信号；
车辆内部音频信号解码降噪模块，用于将所述内部音频信号进行解码和降噪，提取内部音频信号中的内部人声；
车辆内部音频信号效果处理模块，对所述内部人声进行音频效果处理，输出到整车功放；
车辆外部音频信号播放模块，用于通过车外扬声器播放经过音频处理的车辆内部音频信号。
值得注意的是，虽然在本实施例中只披露了一些基本功能模块，但并不意味着本系统的组成仅仅局限于上述基本功能模块，相反，本实施例所要表达的意思是：在上述基本功能模块的基础之上本领域技术人员可以结合现有技术任意添加一个或多个功能模块，形成无穷多个实施例或技术方案，也就是说本系统是开放式而非封闭式的，不能因为本实施例仅仅披露了个别基本功能模块，就认为本发明权利要求的保护范围局限于所公开的基本功能模块。同时，为了描述的方便，描述以上装置时以功能分为各种单元、模块分别描述。当然在实施本发明时可以把各单元、模块的功能在同一个或多个软件和/或硬件中实现。
以上所描述的装置实施方式仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施方式方案的目的。本领域普通技术人员在不付出创造性劳动的情况下，即可以理解并实施。
如图3至图6所示，现有技术存在的问题是车辆内外沟通多为车内和车外间的信息通信，其中借助多控制器(Wi-Fi设备/蓝牙设备)进行通信，同时使用场景一定是熟客方式，车内设备与车外第三方设备建立链接后，方可建立通信。
本实施例基于车载娱乐系统及其信息娱乐控制器等现成的车载设备，解决陌生人车辆内外之间进行通信的问题，且通信场景为车外近距离处(2米 内)，车外通信方不需要提供任何设备，同车内控制器实现车内与车外通信，多用于陌客场景。
硬件上，车外部署模拟麦克风用于拾车外人声，一般部署在驾驶员外部，同时车外还包含扬声器，用户将车内的用户声音播出。车内主要部署信息娱乐控制器(CSC)、车内麦克风、车内功放、车内扬声器。软件上，对声音的降噪处理、以及场景模块均部署在CSC上，通过CSC内部的功能逻辑实现车内外声音的处理和分发。
名词解释：CSC：车载信息娱乐控制器、CODEC：音频编解码芯片
SOC：信息娱乐控制器主芯片、DSP：音频处理芯片
车外麦克风通过硬件将音频传递到车内的信息娱乐控制器CSC上，控制器首先对声音进行解码处理，将音频传递给主芯片上，再进入车外降噪模块，车外降噪模块需要采集功放的回传音，用作降噪参考，对车外的音频进行降噪处理，将环境音等噪声去掉，识别到人声，完成场景对应，再将人声通过控制器内的DSP进行音频效果处理，通过A2B输出到整车功放，最终由车内扬声器播出，进而车内用户可以听见车外用户的声音。
车内麦克风主要是用于采集车内用户的说话音，将采集到的音频文件首先进行解码处理，将音频传递给主芯片上，再进入车内降噪模块，车内降噪模块需要采集功放的回传音，用作降噪参考，对车内的音频进行降噪处理，将车内环境音等噪声去掉，识别到人声，完成场景对应，再将人声通过控制器内的DSP进行音频效果处理，通过A2B输出到整车功放，最终由车外扬声器播出，进而车外用户可以听见车内用户的声音。
A2B通道分配结果如下：
本实施例针对车内外的特殊使用场景，实现无需借助车外设备的情况下实现车内外通信，搭载在一套车载娱乐系统上，控制系统集成在信息娱乐控制器的SOC芯片上，不限于系统类型影响(LINUX\QNX\Android)，通过内部音源流转和技术处理，保证交互的实时和同步性，达成车内用户与车外用户实时交流需求。
作为进一步的改进和/或替换方案，本发明实施例还提供了一种车内外语音声纹交互方案，方法步骤具体包括：
步骤S1：检测到钥匙，车外语音系统激活；
步骤S2：识别用户的唤醒词，或全局免唤醒词进行业务阶段；
步骤S31：车载系统响应唤醒词，并播报回复语句；
步骤S32：全局免唤醒词，直接执行业务。
如图7所示，本发明还公开了与车辆内外通话方法、系统相对应的电子设备和存储介质：
一种电子设备，包括：处理器、通信接口、存储器和通信总线，其中，处理器，通信接口，存储器通过通信总线完成相互间的通信；存储器中存储有计算机程序，当计算机程序被处理器执行时，使得处理器执行车辆内外通话方法的步骤。

上述电子设备提到的通信总线可以是外设部件互连标准(Peripheral Component Interconnect，PCI)总线或扩展工业标准结构(Extended Industry Standard Architecture，EISA)总线等。该通信总线可以分为地址总线、数据总线、控制总线等。为便于表示，图中仅用一条粗线表示，但并不表示仅有一根总线或一种类型的总线。
电子设备包括硬件层，运行在硬件层之上的操作系统层，以及运行在操作系统上的应用层。该硬件层包括中央处理器(CPU，Central Processing Unit)、内存管理单元(MMU，Memory Management Unit)和内存等硬件。该操作系统可以是任意一种或多种通过进程(Process)实现电子设备控制的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。并且在本发明实施例中该电子设备可以是智能手机、平板电脑等手持设备，也可以是桌面计算机、便携式计算机等电子设备，本发明实施例中并未特别限定。
本发明实施例中的电子设备控制的执行主体可以是电子设备，或者是电子设备中能够调用程序并执行程序的功能模块。电子设备可以获取到存储介质对应的固件，存储介质对应的固件由供应商提供，不同存储介质对应的固件可以相同可以不同，在此不做限定。电子设备获取到存储介质对应的固件后，可以将该存储介质对应的固件写入存储介质中，具体地是往该存储介质中烧入该存储介质对应固件。将固件烧入存储介质的过程可以采用现有技术实现，在本发明实施例中不做赘述。
电子设备还可以获取到存储介质对应的重置命令，存储介质对应的重置命令由供应商提供，不同存储介质对应的重置命令可以相同可以不同，在此不做限定。
此时电子设备的存储介质为写入了对应的固件的存储介质，电子设备可以在写入了对应的固件的存储介质中响应该存储介质对应的重置命令，从而电子设备根据存储介质对应的重置命令，对该写入对应的固件的存储介质进行重置。根据重置命令对存储介质进行重置的过程可以现有技术实现，在本发明实施例中不做赘述。

存储介质，用于存储程序，所述程序在运行时，对于从电子设备输出的数据执行所述基于车载娱乐系统的车辆内外通话方法的步骤。
