Description

语音识别是目前智能信息系统人机交互界面的核心技术点。为了提升语音识别的成功率，普遍采用声音采集传感器采集声音信号的方案，针对声音发出位置进行声音信号采集和语音识别。
目前，提高语音识别成功率的方案，只能提取一个位置发出的声音信号，对于其他位置发出的声音信号只能被当做噪声滤除而无法准确地提取和定位声音发出位置，也无法进行语音识别。以安装在汽车内的车载系统为例，目前可以通过安装在车载系统上的声音采集传感器采集周围环境中的声音信号，提取出从主驾驶室发出的声音信号，并对所述提取的从主驾驶室发出的声音信号进行语音识别，车载系统可以响应从主驾驶室发出的声音信号。但是，从副驾驶室发出的声音信号或者从车载后排座位发出的声音信号都被车载系统当做噪声滤除而无法准确地提取和定位声音发出位置，更无法进行语音识别。如，车载系统可以提取并语音识别从主驾驶室发出的“开天窗”的语音命令，但是，无法提取从副驾驶室或者从车载后排座位等其他位置发出的“开天窗”的语音命令，也无法定位车载系统内其他声音信号的发出位置。因此，在汽车内的车载系统这样的应用场景下，车载系统无法高效准确地定位汽车内其他声音信号的发出位置，降低了定位声音信号的发出位置的效率，用户体验低下。

具体实施方式
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。
本发明实施例提供了一种定位声音发出位置的方法，在本发明实施例中，涉及到的终端设备可以为车载中控设备、智能手机、平板电脑等。
在现有技术中，声音采集传感器采集声音信号的方案结合波束成型算法被应用于采集声音信号和语音识别，通过这种方式已经大大提高了语音识别的成功率，但是通过这种方式只能识别单一的一个声音发出位置发出的声音信号，当有多个位置的声音发出位置发出声音信号时，语音识别系统无法同时识别多个声音信号。
在本发明实施例中，第一声音信号或者第二声音信号仅用于区分，并不代表次序或者顺序。
图1是本发明实施例提供的一种定位声音发出位置的方法流程图，本发明实施例的应用场景可以为任意声音采集和语音识别的场景，本发明实施例中，以车载系统中的声音采集和语音识别为例，所述方法包括以下步骤：
S101，采集K个第一声音信号；其中，K为大于等于2的整数。
在车载系统中，车载系统内部有K个声音采集传感器，处理器则可以采集K个第一声音信号；其中，K为大于等于2的整数。
例如，在车载系统中，可以设置K为2，即可以在驾驶室和副驾驶室里分别安装了第一声音采集传感器和第二声音采集传感器。
第一声音采集传感器和第二声音采集传感器同时采集第一声音信号。可选的，在车载系统中，还可以在车载后排座位或车载内其他位置安装其他声音采集传感器。
在本发明实施例中，第一声音信号为车载系统内部的环境声音，包括从车载内不同位置发出的声音信号和车外的声音信号。其中，所述第一声音信号可以包括从驾驶室位置(例如，如图2A所示，位置①)发出的声音信号，从副驾驶室位置(例如，如图2A所示，位置②)发出的声音信号，从车载系统后排座位的位置(例如，如图2A所示，位置③和位置④)发出的声音信号和车载系统外部的噪音中的至少一个。
S102，根据与N个不同位置对应的N个位置参数，从所述K个第一声音信号中提取M个第二声音信号；其中M小于等于N，N为大于等于2的整数。
同样以车载系统的情况为例进行说明，由于第一声音采集传感器和第二声音采集传感器在空间位置上坐标不重合，而且第一声音采集传感器和第二声音采集传感器拉开了一定的距离。如图2A所示，第一声音采集传感器和第二声音采集传感器分别设置在车载系统的中后视镜A的左右两侧。第一声音采集传感器设置在车载系统的位置C，第二声音采集传感器设置在车载系统的位置B。因此，第一声音采集传感器和第二声音采集传感器采集到的声音信号的时间不相同，从而，对于第一声音采集传感器采集到的声音信号和第二声音采集传感器采集到的声音信号会形成一个相位差。
在本发明另一实施例中，如图2B所示，车载系统包括4个声音采集传感器，此时，K为4。所述4个声音采集传感器设置在车载系统的中央位置，如图2B所示。
从所述K个第一声音信号中提取M个第二声音信号，具体可以为利用波束成型算法，从K个第一声音信号中，提取出M个第二声音信号；也可以为利用波束成型算法，从K个第一声音信号中，过滤其他声音信号，提取M个第二声音信号。
例如，声音信号发出的位置为驾驶室位置，对应的位置参数为驾驶室位置的参数，车载中控设备根据与驾驶室对应的驾驶室的位置参数，从所述K个第一声音信号中提取从驾驶室发出的第二声音信号。
S103，确定每个第二声音信号对应的位置。利用波束成型算法，所述车 载中控设备分别根据N个位置参数，从所述K个第一声音信号中提取M个第二声音信号。
例如，当位置参数是驾驶室的位置参数时，利用波束成型算法，根据驾驶室的位置参数，提取第二声音信号，并根据所述第二声音信号对应的位置参数，确定所述提取的第二声音信号对应的发出位置为驾驶室。
本发明提供了一种定位声音发出位置的方法，利用波束成型算法，根据位置参数，从K个第一声音信号中提取M个第二声音信号，从而可以确定每个第二声音信号对应的发出位置。通过这种方法，可以高效的提取不同位置发出的声音信号，提高了语音识别能力，为用户提供了更高的用户体验。
图3是本发明另一实施例提供了一种定位声音发出位置的方法流程图。本发明实施例同样以应用于车载系统为例进行说明，如图3所示，所述方法包括以下步骤：
S301a，设置响应N个不同位置的语音命令的优先级。
同样以图2A的位置示意图为例，图2A中，位置①为驾驶室位置，位置②为副驾驶室位置，位置③为车载系统后排座位左侧的位置，位置④为车载系统后排座位右侧的位置。
在本发明实施例中，以车载系统为例，假设K为2，N为4，M为2。
车载中控设备在车载系统内根据4个不同位置，设置响应4个不同位置的语音命令的优先级。
例如，以普通家用轿车设置的语音命令优先级为例。
命令 开天窗 关天窗 开收音机 播音乐
位置① 1 1 1 1
位置② 1 1 2 2
位置③ 2 2 3 3
位置④ 2 2 4 4
表(1)  普通家用轿车设置的语音命令优先级
从表(1)中可以看出来，当位置①发出如“开天窗”、“关天窗”、“开收音机”或者“播音乐”等命令时，位置①发出命令的优先级高于其他位置发出的同样语义的命令的优先级。
在本发明另一实施例中，设置响应N个不同位置的语音命令的优先级时， 加入儿童和成人声音判断因素。设置语音命令为儿童声音的优先级为低优先级或者设置当语音命令为儿童声音时，屏蔽儿童声音的语音命令，设置语音命令为成人声音的优先级为高优先级。
在本发明实施例中以位置①发出命令“空调启动”和位置④同时发出命令“空调关闭”为例。
S301，采集K个第一声音信号。
在本发明实施例中，以K为2举例说明。
其中，在车载系统中，在中后视镜A的左右两侧分别安装了第一声音采集传感器和第二声音采集传感器。
第一声音采集传感器和第二声音采集传感器同时采集第一声音信号。可选的，在车载系统中，还可以在车载后排座位或车载内其他位置安装其他声音采集传感器。
例如，当位置①发出命令“空调启动”的声音信号和位置④同时发出命令“空调关闭”的声音信号时，第一声音采集传感器和第二声音采集传感器同时采集到位置①发出的命令“空调启动”的声音信号，同样第一声音采集传感器和第二声音采集传感器同时采集到位置④发出的命令“空调关闭”的声音信号。
S302，根据与N个不同位置对应的N个位置参数，从所述K个第一声音信号中提取M个第二声音信号；其中M小于等于N，N为大于等于2的整数。
在本发明实施例中，以N为4，M为2进行举例说明。
由于第一声音采集传感器和第二声音采集传感器在空间位置上坐标不重合，而且第一声音采集传感器和第二声音采集传感器拉开了一定的距离。因此，第一声音采集传感器和第二声音采集传感器采集到的声音信号的时间不相同，从而，对于第一声音采集传感器采集到的声音信号和第二声音采集传感器采集的声音信号会形成一个相位差。
本发明以第一声音采集传感器和第二声音采集传感器设置在中后视镜左右为例，本发明对声音采集传感器的数量不做限制，对声音采集传感器的位置也不做限制。例如，还可以将其他声音采集传感器设置在可能发出声音的位置旁边，如安装在如图2A所示的位置①或位置②的座位的后侧。
例如，车载中控设备根据预置的位置①的位置参数，提取从位置①发出的 第二声音信号。利用波束成型算法，根据预置的位置①的位置参数，车载中控设备从采集的第一声音信号中提取从位置①发出的第二声音信号。
同时，车载中控设备根据预置的位置④的位置参数，提取从位置④发出的第二声音信号。利用波束成型算法，根据预置的位置④的位置参数，车载中控设备从采集的第一声音信号中提取从位置④发出的第二声音信号。
例如，车载中控设备利用波束成型算法，根据位置①的位置参数，提取符合预置的位置①的位置参数的声音信号。如，采集到从位置①发出的“空调启动”的声音信号；车载中控设备利用波束成型算法，根据位置④的位置参数，提取符合预置的位置②的位置参数的声音信号。如，采集到从位置④发出的“空调关闭”的声音信号。
S303，确定每个第二声音信号对应的位置。
利用波束成型算法，所述车载中控设备分别根据4个位置参数，从所述2个第一声音信号中提取2个第二声音信号。
例如，当位置参数是位置①的位置参数时，利用波束成型算法，根据位置①的位置参数，提取从位置①发出的第二声音信号，并根据所述第二声音信号对应的位置参数，确定所述提取的第二声音信号对应的发出位置为位置①。
S304，对提取的所述M个第二声音信号进行语音识别。
车载中控设备对所述提取的声音信号进行语音识别，识别提取的声音信号。
例如，车载中控设备对从位置①提取的声音信号进行语音识别，识别提取出的声音信号为“空调启动”；车载中控设备对从位置④提取的声音信号进行语音识别，识别提取出的声音信号为“空调关闭”。
S305，获取所述M个第二声音信号对应的语音命令。
车载中控设备获取所述提取的M个第二声音信号对应的语音命令。
例如，车载中控设备获取所述提取的位置①发出的声音信号对应的语音命令，获取“空调启动”的语音命令；并且，车载中控设备获取所述提取的位置④发出的声音信号对应的语音命令，获取“空调关闭”的语音命令。
S306，响应所述M个语音命令。
车载中控设备根据获取的所述提取的M个第二声音信号对应的语音命令，响应所述M个语音命令。
例如，车载中控设备获取到从位置①发出的“空调启动”的语音命令后，响应所述语音命令，启动空调。
在本发明另一实施例中，车载中控设备对位置①提取的声音信号和位置④提取的声音信号进行语音识别，识别提取的声音信号。车载中控设备对提取的从位置①发出的声音信号和从位置④发出的声音信号进行语音识别，识别提取的声音信号。获取所述提取的位置①发出的声音信号对应的语音命令，和获取所述提取的位置④发出的声音信号对应的语音命令，例如，获取位置①发出的“空调启动”和位置④发出的“空调关闭”的语音命令。车载中控设备根据获取的提取的位置①发出的“空调启动”和位置④发出的“空调关闭”的语音命令，响应所述2个语音命令。可选的，当车载中控设备语音识别到两个位置的语音命令时，会根据所述2个语音命令对应的2个不同位置的优先级，优先响应高优先级的语音命令，例如，位置①的优先级高于位置④的优先级，车载中控设备先响应位置①的语音命令“空调启动”，从而开启空调。车载中控设备再响应位置④的语音命令“空调关闭”，此时由于车载中控设备响应位置①的语音命令为“空调开启”，位置④的语音命令为“空调关闭”，位置①的语音命令和位置④的语音命令为冲突命令，车载中控设备无法同时响应位置①的语音命令和位置④的语音命令。因此，车载中控设备对位置④的声音信号进行语音识别后，获取提取的声音信号对应的语音命令，不响应位置④的语音命令。通过优先级的方法来处理冲突命令，减少车载中控设备响应多个冲突命令时，由于命令冲突带来的车载中控设备无法做出正确的响应，减少响应错误带来的误差。
其中，所述冲突命令具体为，如果至少两个命令会使用同一资源、且执行所述至少两个命令时，对所述使用的同一资源的操作不同，则所述至少两个命令为冲突命令。
在本发明另一实施例中，当获取的两个语音命令冲突时，增加时间判断因素，当高优先级的命令被识别之后的预设时间T1时间内，车载中控设备识别到冲突命令命令，但是识别到的冲突命令的优先级较低时，则忽略优先级较低的命令命令。若高优先级命令被识别之后的预设时间T1时间之后，车载中控设备识别到冲突命令时，车载中控设备则按照识别到的语音命令的时间顺序来顺序响应获取的语音命令。
图3A是本发明另一实施例提供了一种定位声音发出位置的方法流程图，在本发明另一实施例中，在执行步骤S301之前，还可以执行下列步骤：
S401，判断车载系统的至少一个座位是否坐人。
具体的，车载系统可以通过重力感应的方式判断车载系统的座位是否坐人。
例如，通过重力感应的方式判断图2A中的车载系统的座位是否坐人。如判断图2A中的位置①，位置②，位置③或者位置④是否坐人。
当所述车载系统判断所述车载系统的所有座位都没有坐人时，不执行步骤S301。
当所述车载系统判断所述车载系统的至少一个座位坐人时，执行步骤S301。
在采集声音信号之前，首先判断车载系统的至少一个座位上是否坐人，只有在车载系统的座位上坐人，再来定位声音发出的位置，提高声音采集的效率和提高确定声音发出位置的效率。
在本发明另一实施例中，如图3B所示，可以在执行步骤S305后，执行步骤S305a：识别提取的所述M个第二声音信号的声纹。
S305b：测量车载系统的坐人的座位上，用户的重量。
S305c：结合测量的用户的重量和识别的第二声音信号的声纹，确定所述用户的身份。
S305d：根据所述确定的所述用户的身份，确定所述用户发出的第二声音信号对应的语音命令的优先级。
S305e：根据所述用户发出的第二声音信号对应的语音命令的优先级，响应所述第二声音信号对应的语音命令。
通过结合重力感应和声纹识别的方式，确定用户的身份和用户发出的声音信号对应的语音命令的优先级。结合用户发出的声音信号对应的语音命令的优先级，确定响应多个语音命令的优先级。减小由于需要响应多个语音命令，给车载中控设备系统带来的误差和错误。
本发明提供了一种定位声音发出位置的方法，利用波束成型算法，根据位置参数，从K个第一声音信号中提取M个第二声音信号，从而可以确定每个第二声音信号对应的发出位置。更进一步地，设置语音命令的优先级，通过优 先处理高优先级的方法来处理冲突命令，减少车载中控设备响应多个冲突命令带来的冲突，减少响应错误带来的误差，提高了用户体验。
