AdaSpeech_Involution

基于CVPR2021Involution改正后的AdaSpeech

语音合成个性化是使用少量数据(几分钟或者几秒钟语音)进行语音定制,现有的方案都是先进行basemodel的训练,然后使用少量数据进行微调​。 现有的个性化面临的​挑战:

1)模型需要支持与训练模型不同的声学条件,因为定制的语音在韵律,音色,环境等等都​不同; 2) 需要支持更多的语音定制,则自适应的​参数应该尽可能的少。为了解决以上的两个问题, 实现采用了了AadSpeech,其主要方式

1)为处理不同的声学条件,添加了句子和音素级别声学模型​。 2)为减少更新的参数量,提出conditional layernorm,只更新speaker embedding和该层​即可。

同时,将原有的conv1d层替换为Involution层,极大的提高了训练和推理速度,实验aishell3中一个说话人选取40句约2.5分钟,在1080ti上训练仅仅花费40分钟即可达到很好的效果(demo文件中包好音频比对)

此代码主要为模型,暂不包含详细的预处理和训练部分,未来会整理添加。。。。。
