一种机上信息辅助方法及装置。方法包括：获取目标语音数据(S102)；将目标语音数据进行切分，得到单条语音数据(S104)；根据单条语音数据进行语音识别，生成文本数据(S106)；将单条语音数据和文本数据进行展示(S108)。解决了现有技术中获取管控指令时的便捷性和准确性不够高的技术问题。
Description
本发明涉及航空领域，具体而言，涉及一种机上信息辅助方法及装置，在飞行任务中辅助飞行员进行空管信息的收听、回放、查询等，提高获取管控指令的便捷性和准确性，降低沟通成本，为飞机航行提供安全性的保障。
在空中交通管制中，管制员与飞行员通过陆空语音进行通话，由管制员向飞行员发出管控指令，指挥飞行员按要求操作飞机。管制员角色尤为重要，飞机航行中许多重要的决策都是由管制员根据其与飞行员之间的对话内容而决定的。由于空管的专业性、地域差异性和人员复杂性，空管语音中存在大量专业名词、独特的地区名称、中英文混杂以及口音差异，加之嘈杂环境、通信链路干扰等因素，在实际操作中，很有可能因为极小失误，例如听错信息、遗漏信息等，导致飞行员对管制员语音的误判，进而给航空领域带来巨大的损失。因此，对于机上的飞行员而言，在与空管交流过程中迫切需要一种辅助手段。
随着自然语言处理技术的发展，人们提出采用语音识别作为一种辅助空管信息的技术途径。然而，在空管系统中实现准确高效的语音识别难度较大，主要体现在几个方面：首先，空管系统所处的环境特殊，这直接决定了空管语音识别在语音信息采集环节上的特殊性；其次，空管系统中对数字、字母、航班号、跑道等的发音有特殊定义，而且空管系统中对话语句的结构、顺序需遵循指定的规则，导致普通的语音识别产品无法应用到空管对话识别中；此外，由于在空管系统中极小的语音识别失误也可能造成巨大的损失，因此空管语音识别系统对识别的准确率要求严格。现有技术中存在一些专用于空管的语音识别方法，但普便存在准确率不够高的情况，于是大多被应用在地面场景中，例如用于辅助管制指挥质量评估、事后分析、工作负荷评估等地空通话数据分析工作。因此迫切需要一种在机上辅助飞行员，提高空管沟通便捷性和准确性的方法，为飞机航行提供安全性的保障。
针对上述的问题，目前尚未提出有效的解决方案。

图1是根据本发明实施例的一种机上信息辅助方法的流程图，如图1所示，该方法包括如下步骤：
步骤S102，获取目标语音数据。
具体的，本发明实施例为了实现实时捕获陆地和空中之间的音频语音传输数据，需要建立专用的语音通信链路，并设置语音捕获程序，针对语音通信链路中传输的语音数据进行录制和截取，并将所有的语音数据传输到处理器中，进行后续的语音分析处理。获取目标语音数据可以是在陆地控制设备上进行，也可以是在空中机上语音控制设备来进行，具体选用哪种控制设备进行语音的捕获的传输，在此处不进行具体的限定。
可选的，所述目标语音数据是通过语音通信链路捕获的陆空语音实时通话数据。
具体的，目标语音数据的获取可以是通过语音通信链路进行的、实时地通话数据，由于在陆地和空中飞行员进行语音交流的时候，往往实时性非常重要，实时性的语音通话可以在陆地和空中保持不断更新的动态呼叫，达到安全的效果，因此在捕获语音的时候，需要根据通信链路中的数据进行实时的语音捕获，其中捕获的延迟越小，对陆地空中语音协调控制的影响就越小。
步骤S104，将所述目标语音数据进行切分，得到单条语音数据。
可选的，所述将所述目标语音数据进行切分，得到单条语音数据包括：根据所述目标语音数据，获取语音信息熵，其中，所述语音信息熵表征所述目标语音数据的复杂度；根据所述语音信息熵对所述目标语音数据中的语句进行断句和切分，将切分后的语音数据作为所述单条语音数据进行输出。
具体的，根据所述目标语音数据，获取语音信息熵，其中，所述语音信息熵表征所述目标语音数据的复杂度，本发明实施例在获得了语音数据的复杂度之后才可以根据语音数据的复杂程度、长短程度，自动判定如何进行语音切分工作，切分后的语音 数据可以更效率地进行文字化的语音识别操作。根据所述语音信息熵对所述目标语音数据中的语句进行断句和切分，将切分后的语音数据作为所述单条语音数据进行输出。
需要说明的是，信息熵是一个数学上颇为抽象的概念，在这里不妨把信息熵理解成某种特定信息的出现概率。而信息熵和热力学熵是紧密相关的。根据Charles H.Bennett对Maxwell's Demon的重新解释，对信息的销毁是一个不可逆过程，所以销毁信息是符合热力学第二定律的。而产生信息，则是为系统引入负(热力学)熵的过程。所以信息熵的符号与热力学熵应该是相反的。一般而言，当一种信息出现概率更高的时候，表明它被传播得更广泛，或者说，被引用的程度更高。我们可以认为，从信息传播的角度来看，信息熵可以表示信息的价值。这样子我们就有一个衡量信息价值高低的标准，可以做出关于知识流通问题的更多推论。
信息熵计算公式：
H(x)＝E[I(xi)]＝E[log(2,1/P(xi))]＝-∑P(xi)log(2,P(xi))(i＝1,2,..n)
其中，x表示随机变量，与之相对应的是所有可能输出的集合，定义为符号集,随机变量的输出用x表示。P(x)表示输出概率函数。变量的不确定性越大，熵也就越大，把它搞清楚所需要的信息量也就越大。
步骤S106，根据所述单条语音数据进行语音识别，生成文本数据。
可选的，在所述根据所述单条语音数据进行语音识别，生成文本数据之后，所述方法还包括：将所述单条语音数据和所述文本数据进行存储。
具体的，为了将上述分割之后的单条语音数据进行识别，并将识别后的数据转化为与单条语音数据中内容相对应的文本数据，需要通过语音识别算法对单条语音数据中的每一帧语音数据进行识别，最后将识别出的汉字或字符进行拼接合并，得到完整的文本句子并输出。
例如，单条语音数据播放内容为“空中有雷暴天气，尽快降落”，那么通过语音识别算法识别之后的文字内容为“空中有雷暴天气”、“，”、“尽快降落”。因此最后通过语音文本拼接操作，对上述识别出来的文本内容见进行拼接得到“空中有雷暴天气，尽快降落”的文本数据，进而向飞行员进行显示，提示飞行员尽快进行降落。
步骤S108，将所述单条语音数据和所述文本数据进行展示。
可选的，所述将所述单条语音数据和所述文本数据进行展示包括：播放所述单条语音数据；根据播放的所述单条语音数据，将对应的所述文本数据进行显示。
具体的，在语音数据转化文本数据之后，根据飞行员及地面控制人员的需要，本发明实施例将单条语音数据和文本数据进行同时显示，即在播放语音数据的同时显示 相应的文本数据，以便使用者可以不受对方口音等因素影响，直观地了解语音的内容。如图3所示，图3是根据本发明实施例的种机上空管信息辅助方法的效果示意图，根据图3可以看出当使用者点击语音播放的同时，可以看到语音下方的文本显示，达到了增加使用者获取语音信息准确度的技术效果。
可选的，所述单条语音数据的播放次数为至少一次。
具体的，由于某些重要的语音数据需要不止一次进行播放才可以获取完整的语音信息或命令，所以每一个单条语音数据都可以进行至少一次的播放，即根据使用者需求进行多次播放，以达到完整地执行语音中的内容或命令。
通过上述步骤，可以实现增加获取管控指令时的便捷性和准确性的技术效果。
