下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的音频信号处理方法进行详细地说明。
图1是根据一示例性实施例提供的一种音频信号处理方法的步骤流程图，如图1所示，该方法包括：
步骤101、接收第一输入。
步骤102、响应于第一输入，录入原始音频信号，并显示原始音频信号的录音轨迹。
其中，录音轨迹用于指示原始音频信号的时间轴。
本实施例中，音频信号处理方法可以由手机、笔记本电脑、可穿戴设备等具有显示屏和麦克风等器件的电子设备执行。第一输入用于控制电子设备开始录入原始音频信号，并在显示屏中显示与原始音频信号对应的录音轨迹。原始音频信号为需要录入到电子设备中的声音信号，可以是用户发出的声音信号，也可以是电子设备所处环境中的声音信号。
示例性地，第一输入可以是点击录音界面中的录音按键的点击操作，电子设备可以响应于用户的点击操作，开始录入原始音频信号，并在录音界面中显示录音轨迹。如图2所示，图2是根据一示例性实施例提供的一种聊天界面的示意图，用户可以操作显示屏中的界面显示控件，界面显示控件例如聊天界面 中的虚拟按键，电子设备可以响应于用户对界面显示控件的操作，在聊天界面的底部显示录音界面201，录音界面201的底部显示有虚拟的录音按键202。电子设备可以响应于用户对录音按键202的点击操作，启动麦克风采集声音信号，开始录入原始音频信号。与此同时，电子设备在录音界面201中显示轨迹轴203，并在轨迹轴203上显示录音轨迹204。录音轨迹204用于指示原始音频信号的时间轴，时间轴对应原始音频信号的时间长度，因此录音轨迹204的长度可以表征录入的原始音频信号的时间长度。在原始音频信号的录入过程中，原始音频信号的时间长度不断增加，录音轨迹204的长度与原始音频信号的时间长度同步增加。如图2所示，当电子设备从第0秒开始录入原始音频信号时，录音轨迹204从轨迹轴203的左端开始显示，随着原始音频信号的时间长度的增加，录音轨迹204的长度逐渐增加，在第10秒时，原始音频信号的时间长度为10秒，录音轨迹204对应的时间长度也为10秒，当录制时长达到40秒时，原始音频信号的时间长度为40秒，录音轨迹204对应的时间长度为40秒。
实际应用中，录音轨迹也可以直接在聊天界面中显示，录音轨迹的形式可以包括但不限于图2所示的直线，也可以为曲线、直方图和扇形图等形式。第一输入可以是点击录音界面中的录音按键，也可以是点击电子设备中的实体按键，或者在显示屏中沿预设方向滑动的滑动操作，本实施例对第一输入的具体形式，以及录音轨迹的具体形式不做限制。
步骤103、在录音轨迹上添加至少一个分割标记。
其中，分割标记用于将录音轨迹分割为至少两个轨迹分段。电子设备可以自动在录音轨迹上添加分割标记，也可以响应于用户的输入，在录音轨迹上添加分割标记，通过分割标记将录音轨迹分割为至少两个轨迹分段。
可选地，步骤103可以通过如下方式实现：
在原始音频信号的录入过程中，若接收到第八输入，则在当前时刻对应的录音轨迹的位置上添加分割标记。
示例性地，第八输入可以是点击标记添加按键的用户输入，用户可以通过标记添加按键，在原始音频信号的录入过程中，手动在录音轨迹上添加分割标记。如图2所示，录音界面201中显示有标记添加按键205，在用户说话的过程中，电子设备实时采集用户发出的声音信号，若用户在第10秒时发现表述错误，可以点击标记添加按键205，电子设备可以响应于用户的点击操作，在第10秒对应的录音轨迹的位置上，也即在当前时刻录音轨迹204的末端，添加分割标记206。
在一种实施例中，第八输入可以是直接点击录音轨迹的用户输入，结合上述举例，在原始音频信号的录入过程中，若用户在第10秒时点击录音轨迹204，电子设备可以响应于用户的点击操作，在当前时刻对应的录音轨迹204的末端添加分割标记206。
在另一种实施例中，第八输入可以是双击录音界面的用户输入，结合上述举例，在原始音频信号的录入过程中，若用户在第3秒时双击录音界面201，电子设备可以响应于用户的双击操作，在当前时刻对应的录音轨迹204的末端添加分割标记206。需要说明的是，第八输入的具体形式可以包括但不限于如上所述的点击标记添加按键、点击录音轨迹或双击录音界面的用户操作。
本实施例中，电子设备可以通过分割标记将录音轨迹分割为至少两个轨迹分段。示例性地，如图3所示，图3是根据一示例性实施例提供的另一种聊天界面的示意图，图3为原始音频信号录制完成之后的聊天界面的示意图，结合图2，在原始音频信号的录入过程中，若用户在第40秒时结束原始音频信号的录入，可以再次点击录音按键202，电子设备可以响应于用户的点击操作，停止采集声音信号，得到原始音频信号，并停止增加录音轨迹204的长度，得到如图3所示的、可以表征原始音频信号的时间长度的录音轨迹204。同时，录音轨迹204上显示有用户手动添加的分割标记206，录音轨迹204对应的时间长度为40秒，分割标记206对应的时间点为第10秒，分割标记206在第10秒处将录音轨迹204分割为位于分割标记206左侧的第一轨迹分段和位于分割 标记206右侧的第二轨迹分段。
实际应用中，用户在原始音频信号的录入过程中，若发现当前录入的原始音频信号出现错误，可以及时的在当前时刻对应的录音轨迹的位置上添加分割标记，可以方便用户根据录入过程中添加的分割标记确定需要处理的音频分段，快速的对原始音频信号中有问题的音频分段进行处理。
步骤104、基于分割标记对应的时间轴上的时间点，将原始音频信号分割为对应于轨迹分段的音频分段。
本实施例中，电子设备可以基于分割标记对应的时间点，对原始音频信号进行分割。结合上述举例，原始音频信号的时间长度为40秒，可以基于分割标记206对应的时间点第10秒对原始音频信号进行分割。在录制得到长度为40秒的原始音频信号之后，电子设备可以确定分割标记206对应的时间点第10秒，从原始音频信号的第10秒处对原始音频信号进行分割，将原始音频信号分割为第0秒至第10秒之间的第一个音频分段和第10秒至第40秒的第二个音频分段。第一个音频分段对应录音轨迹204中第0秒至第10秒之间的第一个轨迹分段，第二个音频分段对应录音轨迹204中第10秒至第40秒之间的第二个轨迹分段。
步骤105、基于对轨迹分段的输入，对轨迹分段对应的原始音频信号中的音频分段进行处理，得到目标音频信号。
本实施例中，用户在原始音频信号录入完成之后，可以基于录音轨迹中的轨迹分段，对原始音频信号中的音频分段进行处理，得到目标音频信号。结合上述举例，用户可以通过对第一轨迹分段的处理，实现对第一音频分段的处理，以及通过对第二轨迹分段的处理，实现对第二音频分段的处理，得到目标音频信号。
可选地，步骤104可以通过如下方式实现：
响应于第三输入，从至少两个轨迹分段中确定待删除的轨迹分段；
删除原始音频信号中与待删除的轨迹分段对应的音频分段。
示例性的，第三输入可以是长按轨迹分段的用户输入，若用户长按第一轨迹分段，电子设备可以响应于用户的长按操作，删除第一轨迹分段，并删除原始音频信号中与第一轨迹分段对应的第一音频分段，得到只包括第二轨迹分段的录音轨迹，以及只包括第二音频分段的原始音频信号，即目标音频信号。
在一种实施例中，第三输入可以是拖动轨迹分段的用户输入，若用户长按图3所示的第一轨迹分段，并将第一轨迹分段拖动到录音界面201之外，电子设备可以响应于用户的拖动操作，删除第一轨迹分段，并删除原始音频信号中的第一音频分段。第三输入的形式可以包括但不限于长按轨迹分段或拖动轨迹分段的用户输入。
实际应用中，用户删除录音轨迹中的轨迹分段，可以删除音频信号中对应的音频分段，可以方便用户删除音频信号中存在问题的音频分段，可以解决音频信号中存在问题时，需要重新录入音频信号的问题。
综上所述，本实施例中，电子设备接收第一输入，响应于第一输入，录入原始音频信号，并显示原始音频信号的录音轨迹，通过分割标记将录音轨迹分割为至少两个轨迹分段，并基于分割标记将原始音频信号分割为对应于轨迹分段的音频分段，基于对轨迹分段的输入，对轨迹分段对应的原始音频信号中的音频分段进行处理，得到目标音频信号。用户在音频信号的录入过程中，可以通过轨迹分段将音频信号分割为对应的多个音频分段，通过对轨迹分段的操作，可以对音频信号中存在问题的音频分段进行处理，可以避免重新录制音频信号，从而可以提高语音通讯效率。

步骤401、接收第一输入。
步骤402、响应于第一输入，录入原始音频信号，并显示原始音频信号的录音轨迹。
步骤403、在录音轨迹上添加至少一个分割标记。
可选地，步骤403还可以通过如下方式实现：
响应于第九输入，在录音轨迹中确定分割位置，并在分割位置上添加分割标记。
本实施例中，在完成原始音频信号的录入之后，用户可以手动在录音轨迹上添加分割标记。示例性地，如图5所示，图5是根据一示例性实施例提供的又一种聊天界面的示意图，第九输入可以是对已经添加的至少一个分割标记中的目标分割标记的拖动操作，在完成原始音频信号的录入之后，用户可以长按图3所示的分割标记206，并将分割标记206沿录音轨迹204拖动，电子设备可以响应于用户的拖动操作，确定拖动操作的释放位置，将用户释放分割标记206的位置确定为新的分割位置，并在新的分割位置上添加一个新的分割标记207。用户在拖动分割标记206的过程中，可以沿录音轨迹204向分割标记206的左侧拖动分割标记206，以在分割标记206的左侧添加新的分割标记207，也可以沿录音轨迹204向分割标记206右侧拖动分割标记206，以在分割标记206的右侧添加一个新的分割标记。
在一种实施例中，第九输入可以是直接点击录音轨迹的用户输入，电子设备可以响应于用户的点击操作，确定用户点击的位置为分割位置，并在分割位置上添加一个分割标记。实际应用中，用户可以根据录音时长估计原始音频信号的时间长度，在手动添加分割标记时，可以大概估计需要添加分割标记的分割位置。
在另一种实施例中，电子设备在确定分割位置之后，可以播放分割位置对应的音频内容，以方便用户根据播放的音频内容，调整分割位置。如图5所示，当用户将分割标记206拖动到分割标记207所在的分割位置时，电子设备可以从分割标记207对应的原始音频信号中的时间点开始，播放原始音频信号中的音频内容。此时，用户可以根据播放的音频内容，确定分割标记207对应的分割位置是否为用户需要的分割位置，若分割标记207对应的分割位置不符合需求，用户可以继续拖动分割标记206，在录音轨迹204的其他位置释放分割标 记206，重新确定分割位置，电子设备可以再次播放分割位置对应的音频内容，重复上述步骤直至确定符合用户需求的分割位置，在分割位置上添加分割标记。
在一种场景下，用户在原始音频信号的录入过程中，若确定当前时刻录入的声音信号有问题时，可以在录音轨迹中添加分割标记，例如分割标记206。在原始音频信号录入完成之后，用户可以拖动分割标记，在录音轨迹中添加一个对应的分割标记，例如分割标记207，从而可以从录音轨迹中得到一个需要处理的轨迹分段(即分割标记206和分割标记207之间的轨迹分段)，以对轨迹分段对应的音频分段进行处理。
实际应用中，在原始音频信号录入完成之后，用户可以手动在录音轨迹中添加分割标记，可以方便用户将音频信号分割为相应的几个音频分段，从而可以方便用户对原始音频信号进行分段处理。
可选地，步骤403可以通过如下方式实现：
确定原始音频信号中停顿时长大于或等于预设时长的停顿区间，并确定停顿区间在时间轴上的起始时间和结束时间；
从录音轨迹中确定位于起始时间和结束时间之间的目标轨迹分段，并在目标轨迹分段上添加分割标记。
示例性地，电子设备在原始音频信号的录入过程中，可以对原始音频信号进行检测，确定原始音频信号中的停顿区间，在停顿区间对应的目标轨迹分段上添加分割标记。例如，电子设备在采集用户的声音信号的过程中，若在第10秒开始，采集得到的音频信号的强度小于或等于预设强度阈值，可以确定用户在第10秒开始暂停说话，若强度小于或等于预设强度阈值的情况一直持续到第15秒，则可以确定在第10秒至第15秒之间用户并没有说话，并且第10秒与第15秒之间的时间间隔大于预设时长(预设时长例如4秒)，则可以确定第10秒至第15秒之间的时间段为停顿区间，以及停顿区间在时间轴上的起始时间为第10秒，结束时间为第15秒。此时，电子设备可以在录音轨迹中确定位 于第10秒和第15秒之间的轨迹分段为目标轨迹分段，并在目标轨迹分段的任意位置添加一个分割标记，即在第10秒至第15秒之间的任意位置添加一个分割标记。
需要说明的是，电子设备也可以在原始音频信号录入完成之后，对原始音频信号进行检测，确定原始音频信号中的一个或多个停顿区间，并在录音轨迹的对应位置添加分割标记。停顿区间的确定方法可以包括但不限于根据音频信号的强度确定，预设时长和预设强度阈值的具体数值可以根据需求设置，本实施例对此不做赘述。

步骤404、基于分割标记对应的时间轴上的时间点，将原始音频信号分割为对应于轨迹分段的音频分段。
步骤405、基于对轨迹分段的输入，对轨迹分段对应的原始音频信号中的音频分段进行处理，得到目标音频信号。
可选地，步骤405可以通过如下方式实现：

获取修正音频信号；
采用修正音频信号替换待修改的音频分段，待修改的音频分段为原始音频信号中与待修改的轨迹分段对应的音频分段。
本实施例中，用户可以从原始音频信号中确定待修改的音频分段，并采用新的音频信号替换待修的音频分段，修正音频信号即为新的音频信号。如图5所示，待修改的轨迹分段可以是分割标记206和分割标记207之间的轨迹分段，第二输入可以是双击轨迹分段的用户输入，电子设备可以响应于用户的双击操作，确定分割标记206和分割标记207之间的轨迹分段为待修改的轨迹分段。与此同时，电子设备可以启动麦克风，再次采集一段音频信号，将采集到的新 的音频信号作为修正音频信号，并采用修正音频信号替换原始音频信中分割标记206和分割标记207之间的轨迹分段对应的音频分段。第二输入的具体形式可以根据需求设置，本实施例对此不做限制。
可选地，获取修正音频信号的步骤可以通过如下方式实现：

在一种实施例中，修正音频信号可以是电子设备中预先存储的音频信号。电子设备在确定待修改的轨迹分段之后，可以显示音频列表，音频列表中包括预先存储的多个音频信号，用户可以选择其中的一个音频信号作为修正音频信号。修正音频信号的获取方法可以包括但不限于重新录制音频信号、将文本信息转换为音频信号或者选择预先存储的音频信号的方法，本领域已知或未知的音频信号获取方法都可以应用到本实施例中。
实际应用中，用户可以通过轨迹分段，对原始音频信号中存在问题的音频分段进行替换，可以方便用户对原始音频信号中存在问题的音频分段进行修改，以避免重新录入音频信号，可以提高语音通讯效率。
在一种实施例中，用户在原始音频信号录入完成之后，可以选择直接发送原始音频信号，或者选择对原始音频信号进行处理，得到目标音频信号。

在另一种实施例中，在用户拖动轨迹分段的过程中，电子设备可以显示对应的虚拟轨迹分段。如图8所示，图8是根据一示例性实施例提供的另一种音频发送界面的示意图，在用户拖动第一轨迹分段2011的过程中，电子设备可以显示第一轨迹分段2011对应的虚拟轨迹分段2012，当用户将虚拟轨迹分段2012拖动到目标发送对象401的上方释放时，电子设备可以向目标发送对象401发送第一轨迹分段2011对应的音频分段。
在一种实施例中，用户可以选择直接发送目标音频信号。如图9所示，图 9是根据一示例性实施例提供的又一种音频发送界面的示意图，第七输入可以是双击录音轨迹的用户输入，若用户双击录音轨迹，电子设备可以响应于用户的双击操作，在录音轨迹201的下方显示虚拟录音轨迹2013，虚拟录音轨迹2013对应整段录音轨迹201，此时用户可以拖动虚拟录音轨迹2013，将虚拟录音轨迹2013拖动到目标发送对象的上方并释放。电子设备可以响应于用户的拖动操作，向目标发送对象发送整段目标音频信号。
需要说明的是，在录音轨迹中添加分割标记之后，用户也可以选择不对音频分段进行处理，而是直接进入音频发送界面，选择发送目标音频分段。
实际应用中，用户可以通过轨迹分段选择目标音频信号中的音频分段，将不同的音频分段发送给不同的发送对象，可以实现音频信号的分段发送，可以提高语音通讯效率。
