本实施例中用户可自由选取音频参数对待变声音频信息进行改变，使得获取到的待变声音频信息与变声声音信息存在较大的听觉区别，可以较好地解决现有的变声功能过于简单且人机交互不太方便的问题。
基于上述硬件结构，提出本发明音频变声方法的实施例。
参照图2，图2为本发明音频变声方法第一实施例的流程示意图。
在第一实施例中，所述音频变声方法包括以下步骤：
步骤S10：获取用户的待变声音频信息；
可以理解的是，若智能设备为智能手机时，用户在使用智能手机时，可通过智能手机的麦克风进行音频采集，以获取到用户的待变声音频信息，比如，用户通过麦克风采集自身叙述的音频信息，“世界你好”。当然，获取用户的待变声音频信息的方式也不限于通过智能手机本身的麦克风去实现音频的实时采集，在所述响应于用户输入的变声指令，根据所述变声指令确定对应的第一变声标识之前，也可获取用户输入的文本信息，将所述文本信息转换为待变声音频信息，比如，用户通过智能手机的物理键盘或触摸屏显示的虚拟键盘键入“世界你好”的中文文字，可通过从文本到语音技术（Text To Speech，TTS）将“世界你好”的文字转换为“世界你好”的中文语音，也就获取到了所述待变声音频信息。
步骤S20：响应于用户输入的变声指令，根据所述变声指令确定对应的第一变声标识；
在具体实现中，用户可在智能手机上通过点击变声选项，以实现根据用户选择的变声类型对待变声音频信息进行变声处理。比如，在获取到“世界你好”的待变声音频信息后，智能手机上可显示多种选项以供用户选择，包括“发送”“删除”“重新录制”“变声”等选项，用户可点击“变声”选项，在用户点击“变声”选项后，可提供多种可变声类型的选项给用户选择，比如，“男人”“女人”“小孩”等选项，不同的变声类型选项的音频参数存在区别，在用户选择了“男人”选项了，智能手机可生成对应的变声指令，所述变声指令为用户在智能手机上操作以使智能手机对于待变声音频信息进行变声处理的指令信息。在用户点击“男人”选项后，智能手机可根据变声指令确认用户选取的为“男人”选项，同时确定了对应的第一变声标识，所述第一变声标识用于区别不同类型的变声参数。
步骤S30：根据所述第一变声标识查找对应的第一音频参数；
应当理解的是，由于确定第一变声标识为“男人”，可根据第一变声标识查找对应的第一音频参数，所述第一音频参数用于表现男人声音中的共有特征，比如，由于男性的声带较之女性的声带偏厚，男性在发音时音频频率较低，听起来感觉声音偏宽厚，所以，可将第一音频参数中的音频频率设置为偏低的参数。
当然，本实施例不限制第一变声标识与第一音频参数的类型，所述第一变声标识也可为动物或卡通人物等，第一音频参数则可设置为对应动物或卡通人物的声学参数。
步骤S40：根据所述第一音频参数对所述待变声音频信息进行变声处理，获得变声声音信息。
在具体实现中，在确认第一音频参数后，若第一音频参数为第一变声标识即“男人”对应的音频参数，比如，第一音频参数可包括声音频率参数为82 Hz至392Hz，基准音区为64 Hz至523Hz。可根据所述第一音频参数对用户说出的或文本转语音获取到的“世界你好”进行变声处理，即可将声音频率参数调节至上述声音频率参数以及基准音区范围，并保存变声处理后的音频信息作为变声声音信息。因为，通过改变声音频率，进而可以改变声音的音色以及音调，使得获得的变声声音信息与待变声音频信息在感官上会有较大的不同。当然，在对待变声音频信息进行变声处理时，不限于只改变声音的频率参数，也可调快或调慢播放速度等。
本实施例中用户可自由选取音频参数对待变声音频信息进行改变，使得获取到的待变声音频信息与变声声音信息存在较大的听觉区别，可以较好地解决现有的变声功能过于简单且人机交互不太方便的问题。
参照图3，图3为本发明音频变声方法第二实施例的流程示意图，基于上述图2所示的实施例，提出本发明音频变声方法的第二实施例。
在第二实施例中，步骤S40之后，所述方法还包括：
步骤S50：将所述第一变声标识和所述变声声音信息发送至第一目标设备，以使所述第一目标设备根据所述第一变声标识查找对应的所述第一音频参数，根据所述第一音频参数对所述变声声音信息进行变声还原处理，获得所述待变声音频信息。
在具体实现中，用户在交流时可对自己叙述的音频信息使用本方案进行变声处理，但是，由于对音频信息进行了处理，接收方可能无法直接根据变声声音信息来理解用户表达的意思，因为，变声声音信息可能存在一定的音频损耗，导致听者不易理解。但是，用户在发送变声声音信息后，若考虑到信息的易听性，则需再发一次原本的待变声音频信息，如此则需要用户发送两次语音信息，导致用户使用体验较差。
可以理解的是，为了同时保证使用变声功能的趣味性以及用户操作的简易性，在将变声声音信息发送至第一目标设备时，即发送至接收方时，所述第一目标设备可为智能手机、平板电脑或其他可联网的电子设备，将同时发送第一变声标识和变声声音信息至第一目标设备。接收方在收到第一变声标识和变声声音信息时，可根据第一变声标识确定对应的第一音频参数，并根据所述第一音频参数对所述变声声音信息进行变声还原处理。区别于第一实施例中的变声处理，所述变声还原处理为所述变声处理的逆过程，所述变声处理为通过第一音频参数将待变声音频信息转换为变声声音信息，所述变声还原处理为通过第一音频参数将变声声音信息转换为待变声音频信息。
当然，通过同时将第一变声标识发送至接收方，可以降低接收方识别变声声音信息的计算量，以使接收方确定是通过第一音频参数进行的变声过程。
本实施例中通过接收方对变声声音信息进行还原处理以获得待变声音频信息，实现了在使用变声功能的基础上同时兼顾对于语言表达的正确理解。
参照图4，图4为本发明音频变声方法第三实施例的流程示意图，基于上述图2所示的实施例，提出本发明音频变声方法的第三实施例。
在第三实施例中，步骤S20，具体包括：
步骤S20′：响应于用户输入的变调指令，根据所述变调指令确定对应的变调标识；
可以理解的是，为了满足用户用智能手机进行歌曲演绎的需求，可对用户所演绎的歌曲进行一定的修音处理，比如，对用户所演绎的歌曲进行音调的修正，因为，歌曲具有固定的音谱，而用户在演唱时不一定都是正确的音调，所以，本实施例可对用户所演唱的歌曲进行变调处理，以使得最终获取到的变调声音信息更加地符合原有音谱的音调。具体而言，用户在演唱完一段歌曲以后或者在演唱歌曲的同时，可在智能手机上选择对所唱的歌曲进行变调处理，比如，用户在演唱时，可在智能手机上点击“修音”选项，也就生成对应的变调指令，所述变调指令为开启对用户演唱的音频信息进行变调处理的指令信息，并根据变调指令确定对应的变调标识，所述变调标识用于唯一地确认当前进行变调处理的音频参数。
步骤S30，具体包括：
步骤S30′：根据所述变调标识查找对应的第二音频参数，所述第二音频参数用于将所述待变声音频信息中的音调参数调整为预设音调参数；
在具体实现中，可根据变调标识查找对应的第二音频参数，比如，用户在点击“修音”选项时，可确定当前需要修音的歌曲即用户当前演唱的歌曲，比如，用户当前将演唱“义勇军进行曲”，用户在点击“修音”选项后，可在歌曲选择列表中点击“义勇军进行曲”的选项，所以，所述变调指令中可包括用户点击“义勇军进行曲”的操作信息，则可根据所述变调指令确定对应的变调标识，所述变调标识是指用于唯一地确定音频参数的标识信息，不限于歌曲名称，因为，存在歌曲不同但歌曲名称相同的情况存在。此时，变调标识可为义勇军进行曲。
可以理解的是，可根据义勇军进行曲查找对应的第二音频参数，所述第二音频参数即为义勇军进行曲的音乐简谱。
步骤S40，具体包括：
步骤S40′：根据所述第二音频参数对所述待变声音频信息进行变调处理，获得变调声音信息。
应当理解的是，在获取到义勇军进行曲的音乐简谱后，可根据所述音乐简谱对用户演唱的音频信息进行变调处理，具体而言，通过识别出用户所演唱的连续音调或者文字，来确定当前时刻所演唱的对应音符，同时，将用户当前时刻的音调与简谱中的对应音调进行比对，若不同，则将当前时刻的音调修正为简谱中的对应音调，将修正后的音频信息认定为所述变调声音信息，也就实现了在保证用户的声音音色的基础上让用户所演唱歌曲的音调符合歌曲本身的音调。当然，对于用户所演唱的连续音调或者文字可能存在一定的识别错误，为了降低该种识别错误，可通过智能手机外放歌曲以及显示歌曲歌词的方式，同时采集用户的音频信息，来降低识别错误的情况发生，因为，该种情况下无需确定当前时刻在简谱中所演唱的音符位置，直接默认用户在以正确的音乐节拍进行演唱即可。
本实施例中通过对用户演唱的歌曲进行变调处理，可以较好地对用户自身演唱的歌曲进行音调修正，并且，本实施例提供的方式用户操作简易，且可降低识别错误的情况发生。
参照图5，图5为本发明音频变声方法第四实施例的流程示意图，基于上述图4所示的实施例，提出本发明音频变声方法的第四实施例。
在第四实施例中，步骤S20′至S30′，具体包括：
步骤S201：提取所述待变声音频信息中的用户音调参数；
可以理解的是，为了便于确定变调处理所需的音频参数，存在多种方式以便用户去确定音频参数，比如本实施例中将通过识别用户自身演唱的歌曲音频去确定用户所唱的曲目，在确定用户所演绎的曲目后，即可确定该曲目的音乐简谱，即变调处理所需的音频参数。
在具体实现中，在获取到用户所演唱的待变声音频信息后，将提取出所述待变声音频信息中的用户音调参数，所述用户音调参数是指用户演唱中的连续音调信息。
步骤S202：计算所述用户音调参数与各歌曲音调参数的匹配度；
应当理解的是，为了确定用户当前演唱的歌曲曲目，可计算用户音调参数与各歌曲音调参数的匹配度，所述歌曲音调参数是指各歌曲曲目的音乐简谱对应的连续音阶信息，通过计算匹配度，可以较好地确定用户当前所演唱的曲目。
步骤S203：在所述匹配度大于等于预设匹配阈值时， 统计所述匹配度大于等于所述预设匹配阈值的所述歌曲音调参数的歌曲数量；
在具体实现中，所述预设匹配阈值可为0.7，在所述匹配度大于等于0.7时，可统计匹配度大于等于0.7的歌曲数量，比如，歌曲数量为3，则表示智能手机统计的歌曲曲目中有3首歌与用户演唱的歌曲相似度较高；在所述匹配度小于0.7时，可向用户展示“歌曲未成功识别”的显示信息，以提示用户进行重新演唱以获取新的待变声音频信息。
步骤S204：在所述歌曲数量等于预设数量时，将所述匹配度大于等于所述预设匹配阈值的所述歌曲音调参数作为所述第二音频参数。
应当理解的是，考虑到用户演唱的音调不一定能够较好地符合歌曲的真实简谱音调，以及存在较多的歌曲简谱音调具有一定的相似度，所以，统计到的匹配度大于等于预设匹配阈值的歌曲音调参数的歌曲数量不一定为一。若预设数量为一，在统计到的歌曲数量为一时，则可将匹配度大于等于预设匹配阈值的歌曲音调参数作为所述第二音频参数，即表明智能手机当前确定的唯一的歌曲即为用户所演唱的歌曲。
进一步地，在所述歌曲数量不等于预设数量时，展示所述匹配度大于等于所述预设匹配阈值的所述歌曲音调参数的各歌曲标识，以使用户选取歌曲标识来确定对应的歌曲音调参数。
当然，在所述歌曲数量不为一时，可向用户展示统计出的匹配度大于预设匹配阈值的所有歌曲曲名，所述歌曲标识可为歌曲曲名，鉴于本实施例当前无法更加准确地确定当前歌曲，可通过向用户展示满足要求的所有歌曲曲名以供用户自身去进一步地确定用户所需要或用户正在演唱的歌曲。
本实施例中通过识别用户当前或预先演唱的歌曲音频以确定歌曲的正确曲目，同时，在无法进一步准确地确定歌曲曲目时，可展示满足条件的多个歌曲曲目以供用户进一步地确认。
参照图6，图6为本发明音频变声方法第五实施例的流程示意图，基于上述图4所示的实施例，提出本发明音频变声方法的第五实施例。
在第五实施例中，步骤S20′至S30′，具体包括：
步骤S301：响应于用户输入的当前歌曲标识，根据所述当前歌曲标识查找对应的目标歌曲音调参数，所述目标歌曲音调参数用于记录所述歌曲标识对应的歌曲的音调参数；
可以理解的是，为了便于确定变调处理所需的音频参数，存在多种方式以便用户去确定音频参数，比如本实施例中可通过用户自身输入歌曲标识以直接确定用户所需变调的音乐简谱参数。
在具体实现中，所述当前歌曲标识可为歌曲曲名，比如，用户输入“义勇军进行曲”，可根据该曲名确定对应的义勇军进行曲音乐简谱的音调信息。
步骤S302：将所述目标歌曲音调参数认定为所述第二音频参数。
应当理解的是，可将该义勇军进行曲音乐简谱的音调信息作为第二音频参数，以实现根据该第二音频参数实现变调处理。
进一步地，所述根据所述第二音频参数对所述待变声音频信息进行变调处理，获得变调声音信息之后，根据所述当前歌曲标识查找对应的歌曲音频信息，将所述歌曲音频信息与所述变调声音信息进行混音处理，以获取到对应的混音音频文件。
在具体实现中，用户在无伴奏的环境下进行歌曲演唱，在对演唱的音频信息进行变调处理后，为了进一步地增强表现效果以及提高使用的趣味性，可将变调处理后的变调声音信息与所述歌曲音频信息进行混音处理，以获取到对应的混音音频文件。比如，若用户演唱的歌曲为“义勇军进行曲”，可根据义勇军进行曲的歌曲曲名查找对应的歌曲伴奏，所述歌曲伴奏即为所述歌曲音频信息，并将用户演唱的音频与该歌曲伴奏进行混音处理，即可获得存在歌曲伴奏的人声演唱音频。
进一步地，为了减少智能设备本地的数据存储，所述获取用户的待变声音频信息之后，响应于用户输入的新的变声指令，根据所述新的变声指令确定对应的第二变声标识，将所述第二变声标识发送至服务器，以使所述服务器根据所述第二变声标识查找对应的第三音频参数并反馈所述第三音频参数，根据所述第三音频参数对所述待变声音频信息进行变声处理，获得新的变声声音信息。
当然，为了降低智能设备本身对于音频参数的数据保存量，同时，也是为了简化智能设备的运行方式，可将音频参数保存于服务器侧，所述服务器用于保存变声标识与音频参数的对应关系，以使用户在确定所需的变声标识后，可将该变声标识发送至服务器，在服务器侧根据变声标识确定对应的音频参数，并实时地将用户需要的音频参数发送回智能设备。
可以理解的是，在从服务器侧获取到与第二变声标识对应的第三音频参数后，即可根据第三音频参数进行变声处理，也就简化了智能设备的运行需求。当然，可进一步地提高智能设备的运行效率，在服务器查找到对应的第三音频参数后，可直接根据所述第三音频参数对待变声音频信息进行变声处理，在获取到变声声音信息后，将所述变声声音信息发送回智能设备，也就实现了将变声处理的操作迁移至服务侧执行，降低了智能设备的设备计算量。所以，在将第二变声标识发送至服务器时，可同时将待变声音频信息发送至服务器侧。
本实施例中通过用户直接输入当前歌曲标识来确定对应的第二音频参数，比之第四实施例，本实施例可以更快地确定音频参数。
此外，本发明实施例还提出一种存储介质，所述存储介质上存储有音频变声程序，所述音频变声程序被处理器执行时实现如下操作：
