在本实施例中，该显示方法包括：
步骤S10，在第一显示界面显示预设类型的显示数据时，控制录音设备对当前环境进行实时录音操作；
本实施例的显示方法适用于投影仪、智能电视、智能显示器等显示设备，用户可以在需要进行投影或者显示数据、文件时，发送显示指令至投影仪、智能电视、智能显示器等显示设备对应的处理器。在接收到显示指令时，处理器获取所述显示指令对应的待显示数据，其中，预设类型的显示数据包括PPT文档、word文档、PDF文档等。本实施例的显示方法适用于会议室、会场等场所。本实施例中，显示设备包括多个显示界面或者包括多个显示屏，处理器控制显示设备在其第一显示界面显示所述待显示数据，例如，在一种情况下，显示设备包括智能电视、智能显示屏、荧幕等，处理器可以控制智能电视、智能显示屏或荧幕显示待显示数据。本实施例的运行场景中还设有与处理器连接的录音设备，在第一显示界面显示预设类型的显示数据时，处理器可以控制录音设备对当前环境进行实时录音操作，以实现在用户进行讲话时，进行实时录音。
步骤S20，定时将所述录音操作获得的音频信息进行文字识别以获得文字信息，并在第二显示界面显示获得的所述文字信息。
本实施例中，可以采用现有的语音识别算法将录音操作获得的音频信息进行文字识别，以将音频信息转换为文字信息，并在第二显示界面显示获得的所述文字信息，其中，第一显示界面与第二显示界面可以为同一显示设备的两个不同的显示区域，也可以为两个不同的显示设备的显示区域。
进一步的，在一实施例中，该显示方法还包括：在第一显示界面显示预设类型的显示数据时，将当前环境中的照明设备的亮度调整至预设亮度。对应的，可以在显示设备关闭后，或者在文字信息以及待显示信息显示结束后，恢复当前环境中处于工作状态的照明设备的亮度。
通过在第一显示界面显示预设类型的显示数据时，将当前环境中的照明设备的亮度调整至预设亮度，例如降低当前环境中处于工作状态的照明设备的功率，以将当前环境内的灯光调暗等，降低当前环境的亮度，提高第一显示界面及第二显示界面显示数据/文字的清晰度，提高用户的视觉效果，其中，预设亮度可以为在当前环境中用户观看第一显示界面及第二显示界面时视觉效果较佳的亮度。在第一显示界面及第二显示界面显示的数据/文字显示完成以后，恢复当前环境中处于工作状态的照明设备的亮度，即将当前环境中处于工作状态的照明设备的亮度恢复至调整之前的亮度，以保证当显示完成后前环境的亮度。
进一步的，在另一实施例中，在步骤S20之后，该显示方法还包括：存储所述文字信息。将音频信息进行文字识别获得的文字信息进行存储，以减少与会人员对演讲者的讲话内容进行手动记录，提高了会议中记录的效率。
本实施例中，通过在第一显示界面显示预设类型的显示数据时，控制录音设备对当前环境进行实时录音操作，然后对所述录音操作获得的音频信息进行文字识别以获得文字信息，并在第二显示界面显示获得的所述文字信息，实现了在显示待显示数据的同时显示音频信息对应的文字信息，减少演讲者在讲话的同时在白板等设备上书写讲话的相关内容以及与会人员对讲话内容的实时记录，进而提高了会议的效率。
基于第一实施例提出本发明显示方法的第二实施例，参照图2，在本实施例中，步骤S20包括：
步骤S21，计算所述文字信息中的各个词语或语句出现的次数；
本实施例中，在对音频信息进行文字识别获得文字信息时，计算文字信息内的各个词语或语句出现的次数，当然，也可以计算所有音频信息进行文字识别获得文字信息的词语或语句出现的次数。
步骤S22，获取所述文字信息中出现次数大于预设次数的词语或语句；
其中，预设次数可以由用户自行设定。处理器根据计算获得的文字信息内的词语或语句出现的次数，获取文字信息中出现次数大于预设次数的词语或语句。
步骤S23，在第二显示界面显示获得的所述文字信息，并突出显示出现次数大于预设次数的词语或语句。
其中，突出显示出现次数大于预设次数的词语或语句可以为将出现次数大于预设次数的词语或语句进行黑体显示、斜体显示、对出现次数大于预设次数的词语或语句设置下划线、将出现次数大于预设次数的词语或语句的字体放大等。
本实施例中，通过计算所述文字信息中的各个词语或语句出现的次数，接着获取所述文字信息中出现次数大于预设次数的词语或语句，然后在第二显示界面显示获得的所述文字信息，并突出显示出现次数大于预设次数的词语或语句，实现了突出显示出现次数大于预设次数的词语或语句，进而体现了演讲者讲话内容的重点，提高了会议的效率。
基于第一实施例提出本发明显示方法的第三实施例，参照图3，在本实施例中，在所述预设类型的显示数据为PPT时，步骤S20包括：
步骤S24，获取所述PPT的各个标题；
容易理解，一般情况下，PPT文件包含各级标题，因此在显示PPT时，获取该PPT的各个标题，包括PPT的各级标题。
步骤S25，在所述文字信息中查找与所述PPT的各个标题匹配的文字；
在音频信息进行文字识别得到的文字信息中查找与所述PPT的各个标题匹配的文字，例如，包含某一标题的语句等。
步骤S26，分别在所述PPT的各个标题对应的显示区域显示查找到的所述文字，并在第二显示界面显示所述文字信息中除查找到的所述文字之外的其他文字。
其中，PPT的各个标题对应的显示区域可以为各个标题四周的空白显示区域，分别在所述PPT的各个标题对应的显示区域显示查找到的所述文字，并在第二显示界面显示所述文字信息中除查找到的所述文字之外的其他文字。以使与会者清楚的查看与该PPT相应的文字信息。
进一步地，在其他实施例中，在步骤S26之后，该显示方法还包括：在所述PPT播放结束时，在所述第一显示界面显示所述文字信息。目前，在参与会议时，在PPT播放结束后，用户一般会进行相应的总结等，因此在所述第一显示界面显示所述文字信息，以便于所有与会者查看用户总结时发言的文字信息。
本实施例通过获取所述PPT的各个标题，接着在所述文字信息中查找与所述PPT的各个标题匹配的文字，然后分别在所述PPT的各个标题对应的显示区域显示查找到的所述文字，并在第二显示界面显示所述文字信息中除查找到的所述文字之外的其他文字，实现了分别在PPT的各个标题对应的显示区域显示与所述PPT的各个标题匹配的文字，进而使得与会者能够清楚的查看与该PPT相应的文字信息，提高了会议的效率。
