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。
图1表示本发明的音频处理方法的实施例的步骤流程图，该方法可以应用于电子设备，如图1所示，该方法可以包括步骤101至步骤106。
步骤101，获取待处理音频对应的文本信息，所述文本信息包括待处理文本及所述待处理文本中各个字段对应的播放时段。
本发明实施例中，待处理音频可以是存储在本地的音频，也可以是从网上下载得到的需要修改的音频，待处理音频可以是通过音频录制直接得到的，也可以是录制视频过程中录制的，即，待处理音频可以是从视频中提取出的音频。进一步地，待处理文本可以是待处理音频所对应的文本，该对应的文本可以是根据音频转文字的方法，对待处理音频进行转换得到的。待处理文本中各个字段对应的播放时段，可以是该字段对应的音频在待处理音频中对应的播放时段。示例的，假设待处理文本中字段“好心情”对应的音频在待处理音频中对应的播放时段为第5.1秒至第5.9秒，那么可以将播放时段“第5.1秒至第5.9秒”确定为字段“好心情”对应的播放时段。
步骤102，接收针对所述待处理文本的第一输入。
本发明实施例中，针对待处理文本的第一输入，可以是在显示待处理文本的界面上，对待处理文本中需要修改的字段进行选择的操作。该操作可以是单击、双击等等。
步骤103，响应于所述第一输入，根据所述第一输入指示的字段，确定所述待处理文本中的待处理字段。
本发明实施例中，第一输入指示的字段指的是用户通过第一输入选择的字段，即，用户需要修改的音频所对应的字段，因此，可以根据第一输入指示的字段，确定待处理字段。根据第一输入指示的字段，确定待处理文本中的待处理字段时，可以是将待处理文本中第一输入指示的字段作为待处理字段。
步骤104，接收针对所述待处理字段的第二输入。
本发明实施例中，针对待处理字段的第二输入，可以是在显示待处理文本的界面上执行的，第二输入可以是用户根据对待处理字段对应的音频段的修改需求执行的。例如，该第二输入可以是针对待处理字段的删除操 作，或者是输入用于替换待处理字段的操作，或者是输入需要添加的字段的操作，又或者是输入用于替换待处理字段所对应音频段的音频段的操作。
步骤105，响应于所述第二输入，获取目标音频段。
本发明实施例中，目标音频段可以是用户最终想要的音频段。该目标音频段可以是用户直接输入的，也可以是电子设备通过对待处理字段进行编辑，获取到的。其中，对待处理字段编辑的具体方式可以是根据第二输入决定的。例如，可以在第二输入是输入需要添加的字段的操作时，为待处理字段中添加新的字段。在第二输入是针对待处理字段的删除操作时，删除待处理字段，等等。由于第二输入是用户根据对待处理字段对应的音频段的修改需求执行的，因此，通过对待处理字段进行编辑，可以确保获取到的目标音频段即为用户最终想要的音频对应的字段。
步骤106，根据所述目标音频段，对所述待处理字段对应的播放时段处的音频段进行修改，得到目标音频。
本发明实施例中，根据目标音频段进行修改时，可以在文本信息中包含的各个字段对应的播放时段中，读取待处理字段对应的播放时段，然后将待处理字段对应的播放时段处的音频段修改为目标音频段，进而实现对待处理音频的修改。
综上所述，本发明实施例提供的音频处理方法，会先获取待处理音频对应的文本信息，其中，文本信息包括待处理文本及待处理文本中各个字段对应的播放时段，再接收针对待处理文本的第一输入，响应于该第一输入，根据第一输入指示的字段，确定待处理文本中的待处理字段，接着，接收针对待处理字段的第二输入，响应于该第二输入，获取目标音频段，最后，根据目标音频段，对待处理字段对应的播放时段处的音频段进行修改，得到目标音频。这样，无需手动调整进度条，即可实现对音频的修改，因此可以提高音频处理效率。
图2-1表示本发明的音频处理方法的另一实施例的步骤流程图，该方法可以应用于电子设备，如图2-1所示，该方法可以包括步骤201至步骤207。
步骤201、获取待处理音频对应的文本信息，所述文本信息包括待处 理文本及所述待处理文本中各个字段对应的播放时段。
本发明实施例中，电子设备可以通过下述步骤2011～步骤2013实现获取待处理音频对应的文本信息：
步骤2011、检测是否存在与所述待处理音频匹配的字幕文件，所述字幕文件包括字幕文本及所述字幕文本中各个字段对应的播放时段。
本发明实施例中，待处理音频可以是视频中的音频，相应地，字幕文件可以是与视频匹配的字幕文件。待处理音频也可以是独立的音频，比如，歌曲等，相应地，字幕文件可以是与歌曲相匹配的歌词文件。检测是否存在与待处理音频匹配的字幕文件，可以是在网上搜索是否有与待处理音频相匹配的字幕文件，也可以是在本地搜索是否有匹配的字幕文件。
步骤2012、若存在与所述待处理音频匹配的字幕文件，则将所述字幕文件作为所述待处理音频对应的文本信息。
本发明实施例中，将字幕文件作为待处理音频对应的文本信息，可以是将字幕文件中包含的字幕文本作为待处理音频对应的待处理文本，并将字幕文本中各个字段对应的播放时段作为该字段在待处理音频中的播放时段。通过检测是否存在匹配的字幕文件，在存在字幕文件的情况下，将字幕文件作为待处理音频对应的文本信息，可以省去根据音频生成文本的步骤，进而一定程度上节省音频处理的时间。
步骤2013、若不存在与所述待处理音频匹配的字幕文件，则将所述待处理音频中包含的音频转换为文本，并根据所述待处理音频中音频段播放的时间信息，生成所述文本中各个字段对应的播放时段，将所述文本与所述文本中各个字段对应的播放时段，作为所述待处理音频对应的文本信息。
本发明实施例中，将待处理音频转换为文本，可以是利用语音转文字的方法实现的。具体的，可以先对音频进行处理，以去除音频中的杂音，避免对转换过程造成干扰，然后，再提取音频中的特征值，并将音频划分为更小的音频段，使得该音频段中包含一个或多个特征值，根据音频段的特征值与音频模型库中的模型特征值进行匹配，将匹配得到的模型特征值对应的文字，确定为该音频段对应的文本。生成文本中各个字段对应的播放时段，可以是在音频转换为文本的过程中，读取将划分的音频段对应的 播放时段，然后，将划分的音频段对应的播放时段，作为该字段对应的播放时段。这样，在不存在字幕文件的时候，通过音频生成对应的文本，可以得到与待处理音频相匹配的文本内容，进而确保能够为后续提供到准确的文本信息。
步骤202、接收针对所述待处理文本的第一输入。
本发明实施例中，可以接收针对待处理文本的第一输入之前，通过下述步骤实现显示待处理文本：
显示预设画面，并在所述预设画面中显示所有的所述待处理文本；或者，显示所述待处理视频的各个视频画面，在所述视频画面中显示与所述视频画面对应的待处理文本。
具体的，预设画面可以是根据实际情况预先设置的，示例的，预设画面可以与待处理音频存在关联的画面，例如，可以是待处理音频所属视频的视频封面，或者是待处理音频所属的音频专辑的封面，又或者是待处理音频的演唱者的照片，等等，本发明实施例对此不作限定。进一步地，通过在预设画面中显示所有的待处理文本，可以方便用户直观看到完整待处理文本，同时使用与待处理文本相关的预设画面，可以提高用户的观看体验。示例的，图2-2表示本发明实施例提供的显示待处理文本的示例的示意图，如图2-2所示，在包含演唱过待处理音频的某一演唱者的相关画面中，显示所有的待处理文本。需要说明的是，实际应用场景中，待处理文本的数量可能较多，而受到电子设备屏幕尺寸的限制，可能无法一次性显示出完整的待处理文本，因此，可以在对待处理文本进行滚动显示，以确保能够完整显示。
进一步地，也可以显示视频画面，并在视频画面中显示对应的待处理文本。其中，视频画面对应的待处理文本，可以是播放时段与该视频画面所在播放时段相同的文本。由于视频画面的内容与视频画面对应的待处理文本往往具有较强的关联，因此，这样，分别在视频画面中显示的方式，可以方便用户同时观察到视频画面的内容及文本内容，进而方便用户进行选择。具体在显示时，可以是在视频画面上生成文本显示框，在文本显示框中显示待处理文本，该显示框的具体形式可以根据实际情况预先设定。 示例的，图2-3表示本发明实施例提供的显示待处理文本的另一示例的示意图，如图2-3所示，在视频画面中显示有对应的待处理文本，即“让我掉下眼泪的不止昨夜的酒”。
相应地，电子设备可以通过接收对显示的待处理文本的选择输入，实现接收第一输入。这样，通过在预设画面或视频画面中显示待处理文本，可以为用户提供可视化的选择场景以及丰富的信息，使用户能够便捷的选择出待处理文本，提高选择效率。
步骤203、响应于所述第一输入，根据所述第一输入指示的字段，确定所述待处理文本中的待处理字段。
具体的，将待处理文本中第一输入指示的字段确定为待处理字段时，可以是从所有待处理文本中搜索包含的所有第一输入指示的字段，然后将搜索到的字段确定为待处理字段；其中，第一输入指示的字段可以是用户针对显示的待处理文本的选择输入所选中的字段。或者，第一输入可以是通过预设搜索区域执行，第一输入指示的字段可以是通过该搜索区域输入的。相应地，电子设备可以在本步骤之前，显示搜索区域；然后接收用户通过所述搜索区域执行的第一输入。这样，用户仅需选择一次，即可实现控制电子设备对所有相同字段的进行修改，进而可以提高选择效率。
进一步地，在执行步骤203之后还可以通过下述步骤A～步骤C实现调整音频音量。
步骤A、接收针对所述待处理文本的第三输入。
本发明实施例中，针对待处理文本的第三输入，可以是在显示待处理文本的界面上执行的，第三输入可以是对待处理文本字体的调整操作。用户可以在需要对待处理文本字体进行调整时，执行第三输入，相应地，电子设备可以接收该第三输入。
步骤B、响应于所述第三输入，对所述第三输入所指示的待调整字段的字体大小进行调整，得到调整后的待调整字段。
本发明实施例中，对第三输入所指示的待调整字段的字体大小进行调整，可以是根据第三输入指示的调整操作，对待调整字段字体大小进行放大或缩小，得到调整后的待调整字段。
步骤C、根据所述调整后的待调整字段的字体大小，调整所述待调整字段对应音频的音量大小，其中，所述调整后的待调整字段的字体越大，所述待调整字段对应音频的音量越大。
本发明实施例中，根据调整后的待调整字段的字体大小，调整待调整字段对应音频的音量大小时，可以是先确定调整后的待调整字段的字体大小，然后根据预设的字体大小与音量大小对应关系，确定调整后的待调整字段的字体大小所对应的音量，最后，将该待调整字段对应音频的音量大小设置为该待调整字段对应音频的音量，进而实现音量调整。其中，该预设的字体大小与音量大小对应关系中，字体越大，音量越大。
示例的，假设调整后的待调整字段的字体大小为四号，四号字体对应的音量为60分贝，那么相应地，可以将该待调整字段对应音频的音量大小设置为该60分贝。这样，用户仅需对文本字体大小进行调整，即可相应地控制调整对应音频的音量大小，使得音频音量调整的过程更为简便，进而可以提高调整效率。
进一步地，本发明实施例还可以预先设置用于调整字体大小的曲线。相应地，用户可以从待处理文本中选择需要调整字体大小的待调整字段，然后调整该曲线的形状，进而实现输入第二输入。进一步地，在对字体大小进行调整时，可以根据调整后的曲线的各个分段的高度，依次对待调整字段中包含的各个字的大小进行调整；其中，分段的高度可与该字的大小成正比，或成反比。这样，用户只需对曲线形状进行调整，就可实现对应音频段的音量大小。同时，由于曲线形状的多样性，使得待处理字段对应的音频段的音量大小具有多种可能，例如，用户可以通过将曲线调整为波浪形，控制待调整字段对应的音量忽大忽小，进而可以提高音频的趣味性。
步骤204、接收针对所述待处理字段的第二输入。
具体的，本步骤的实现方式可以参照前述步骤104，本发明实施例对此不作限定。
步骤205、根据所述第二输入，对所述待处理字段进行编辑，得到目标字段。
本发明实施例中，若所述第二输入为删除输入，则可以认为用户需要 删掉待处理字段，因此，可以将所述待处理字段删除，并将删除后得到的空白字段确定为所述目标字段。
进一步地，若所述第二输入为替换输入，则可以认为用户需要对待处理字段进行替换，因此，可以获取所述第二输入对应的待替换字段；将所述待处理字段删除并在所述待处理字段的位置，添加所述待替换字段，得到所述目标字段。其中，获取第二输入对应的待替换字段，可以是提取第二输入中包含的字段，将该字段作为待替换字段，也可以是提取第二输入中包含的语音，并根据语音转文字的方法得到该语音对应的文字，将得到的文字作为待替换字段。
进一步地，若所述第二输入为增加输入，则可以认为用户需要对待处理字段添加新的字段，因此，可以获取所述第二输入对应的待增加字段；在所述待处理字段的位置，添加所述待增加字段，得到所述目标字段。本发明实施例中，获取第二输入对应的待增加字段，可以是提取第二输入中包含的字段，将该字段作为待增加字段，也可以是提取第二输入中包含的语音，并根据语音转文字的方法得到该语音对应的文字，将得到的文字作为待增加字段。在本发明实施例中，通过根据不同的第二输入可以执行相应的编辑操作，进而可以满足用户多种的修改需求，提高音频修改效果。
需要说明的是，还可以为显示的待处理字段增加预设标记，以及，根据待处理字段对应的显示位置，显示待替换字段或待增加字段。具体的，预设标记可以是反映对待处理字段执行的具体编辑操作的标记，不同的编辑操作对应的预设标记不同。示例的，若编辑操作为将待处理字段删除，则预设标记可以为在待处理字段上添加的删除线，也可以为在待处理字段上添加表示该字段被删除的文字标记。若编辑操作为替换待处理字段，则预设标记可以为在待处理字段上添加的下划线，也可以为在待处理字段上添加表示该字段被替换的文字标记，并在待处理字段旁显示待替换字段，具体的显示位置可以根据实际情况设定。若编辑操作为在待处理字段的位置增加字段，则预设标记可以为在待处理字段对应的位置处添加增加字段标记，比如箭头等，以指示在该位置处添加字段。同时可以显示添加的待增加字段，以方便用户获知具体添加了什么字段。具体的标记方式可以是 多样的，本发明实施例对此不作限制。通过在待处理字段上添加预设标记，可以使得用户可以更清楚的获知示被修改的待处理字段所在位置，以及具体对其所执行的编辑操作。
进一步地，显示位置可以是根据实际需求预先设定，示例的，该显示位置可以是待删除字段的下方。这样，通过在待删除字段对应的显示位置中显示待替换字段或待增加字段，可以方便用户快速获知具体修改的内容，进而方便用户之后进行检查。
示例的，图2-4表示本发明实施例提供的编辑待处理文本的示例的示意图，如图2-4所示，待处理字段为“让我掉下眼泪的”，而第二输入为删除输入，则删除待处理字段，即在“让我掉下眼泪的”上添加删除线并删除。
图2-5表示本发明实施例提供的编辑待处理文本的另一示例的示意图，如图2-5所示，待处理字段为“眼泪”，而第二输入为替换输入，则删除待处理字段并显示待替换字段，即在“眼泪”上添加删除线，待处理字段下方的“口水”为待替换字段。
图2-6表示本发明实施例提供的编辑待处理文本的又一示例的示意图，如图2-6所示，待处理字段指示的位置为“我”和“掉”之间，而第二输入为增加输入，则用箭头指示待处理字段的位置，箭头下方的“今天”为待增加字段。
步骤206、将所述目标字段对应的音频，确定为所述目标音频段。
具体的，可以先对文本进行语言学分析将目标字段切分为词语，再根据切分得到的词语，从语音合成库中提取匹配的字段对应的音频波形段，将各个词语对应的音频波形段合成，得到该文本对应的音频段。也可以是在待处理音频中检索是否存在与目标字段相同的字段，若存在，则提取该相同字段对应的音频段，作为目标字段对应的音频，进而得到目标音频段。
步骤207、根据所述目标音频段，对所述待处理字段对应的播放时段处的音频段进行修改，得到目标音频。
具体的，本步骤中可以先从各个字段对应的播放时段中获取待处理字段对应的播放时段，然后，获取所述待处理音频对应的音频波形图，最后， 将待处理字段对应的播放时段在音频波形图中的对应波段，修改为目标音频段对应的音频波段，得到目标音频。
其中，获取待处理字段对应的播放时段时，可以从各个字段中查找该待处理字段，然后读取该待处理字段对应的播放时段。获取待处理音频对应的音频波形图时，可以是通过提取音频中包含的特征，比如振动频率等，对该特征进行处理，比如归一化处理等，得到根据播放时间显示音频特征的波形图。
进一步地，将待处理字段对应的播放时段在音频波形图中的对应波段，修改为目标音频段对应的空白波段时，可以使用该空白波段对该对应波段进行替换，以实现修改。或者，也可以是直接将该对应波段删除，以实现修改。需要说明的是，在删除时，可以是去掉该对应波段的波形显示，将其改成直线，以示声音被删除。
若目标字段为待替换字段，可以直接使用目标音频段对应的音频波段对该对应波段进行替换，也可以是先将该对应波段删除，然后在删除的位置上添加目标音频段对应的音频波段中待替换字段对应的音频波段。若目标字段为待增加字段，可以直接使用目标音频段对应的音频波段对该对应波段进行替换，也可以根据待处理字段对应的播放时段在音频波形图中对应波段的位置，添加目标音频段对应的音频波段中待增加字段对应的音频波段，将合成得到的音频波段作为目标音频。这样，通过在音频波形图中对应修改待处理音频的波段，实现对待处理音频的修改，可以使得修改过程更加精准，进而可以提高修改的准确性。
需要说明的是，电子设备还可以在获取到音频波形图之后，执行下述操作：
显示所述待处理音频对应的音频波形图；对所述待处理字段对应的播放时段在所述音频波形图中的对应波段，进行标记。其中，标记可以是将对应波段填充不同的颜色，也可以是在对应波段的位置处添加标注，具体的标记形式本发明实施例不作限制。这样，通过显示待处理音频对应的音频波形图，并在在音频波形图中标记待处理字段对应的波段，可以方便用户查看被修改的音频波段。
需要说明的是，在修改音频波段之前，还可以对待处理音频进行处理，将待处理音频中的人声与背景音进行分离，然后，提取待处理音频中的人声，并对该人声对应的音频波段进行相应地修改，最后，将修改后的人声与背景音合成，得到目标音频。这样，通过只针对人声的修改，而保留音频中的背景音，可以极大地减少对音频的修改程度，使得修改后的音频更加自然，连贯。
综上所述，本发明实施例提供的音频处理方法，会先获取待处理音频对应的文本信息，其中，文本信息包括待处理文本及待处理文本中各个字段对应的播放时段，再接收针对待处理文本的第一输入，响应于该第一输入，根据第一输入指示的字段，确定待处理文本中的待处理字段，接着，接收针对待处理字段的第二输入，根据该第二输入，对待处理字段进行编辑，得到目标字段，将目标字段对应的音频，确定为目标音频段，最后，根据目标音频段，对待处理字段对应的播放时段处的音频段进行修改，得到目标音频。这样，通过根据不同的第二输入可以执行相应的编辑操作，进而可以满足用户多种的修改需求，提高音频的修改效果。同时，用户无需手动调整进度条，即可实现对音频的修改，因此可以提高音频处理效率。

步骤305、提取所述第二输入中携带的音频段。
本发明实施例中，第二输入可以为音频录制操作，相应地，第二输入中携带的音频段可以是用户录制的语音段。第二输入也可以为音频上传操作，相应地，第二输入中携带的音频段，也可以是用户选择要上传的音频段。
步骤306、将所述音频段确定为所述目标音频段。
本发明实施例中，由于第二输入往往是根据用户对待处理字段对应的音频段的修改需求执行的，即，第二输入中携带的音频段即为用户最终想要的音频段。因此，可以直接将该音频段确定为目标音频段。
需要说明的是，本发明实施例中，还可以在将输入的音频段确定为目标音频段之前，提示用户是否要对输入的音频段进行处理，若是，根据用户操作对输入的音频段进行截取，将截取得到的音频段作为目标音频段。这样，通过提示用户是否处理输入的音频段，可以进一步提高目标音频段的质量。
步骤307、根据所述目标音频段，对所述待处理字段对应的播放时段处的音频段进行修改，得到目标音频。
具体的，本步骤的实现方式可以参照前述步骤207，本发明实施例对此不作限定。
