vits-singing-voice-conversion

vits singing voice conversion based on ppg & hubert

VI-SVC model is just VITS without MAS and DurationPredictor. Big data [more and more wave] make things to be interesing!

使用开源库实现的用于特定场景的独有代码，就不能是原创？在svc-develop-team那里竟1+1=2的常识？

大部分数学推导都由四则运算实现，按svc-develop-team的逻辑，所有使用四则运算的数学推导都不构成原创？

这就是svc-develop-team违反开源协议理由，窃取别人代码，还反过来各种贼喊捉贼？

直接拷贝代码文件，都还能说成来自world库的示例，一个人竟然可以无耻到这样的地步，真的是刷新了我的认知。

svc-develop-team说上面代码是world库的示例，请把代码链接放出来？

直接拷贝代码文件都能说的如此无耻，更何况代码背后还涉及的系统架构、设计思想等没法举证的呢？高知青年就这样？

可以看到，只有在使用从本项目拷贝的代码后，svc-develop-team的项目才步入正轨，之前都是瞎搞

但svc-develop-team，在消化融合本项目代码后，将本项目的项目信息删除，理由竟然是相关代码为world库示例，那可是直接拷贝的代码

在svc-develop-team的强盗逻辑中，基于开源库实现的功能都不是原创，这就不奇怪他们能将BigVGAN称为他们原创HiFiGAN-with-snake声码器了

维权无果后，开发了so-vits-svc-5.0

开发so-vits-svc-5.0某些意义上就是了为维权，证明我能做的比svc-develop-team好

然而svc-develop-team恬不知耻的再次来拷贝代码，具体包括so-vits-svc-5.0中的whisper和bigvgan等相关代码

面对svc-develop-team不遵守开源协议和贼喊捉贼的行为，本人在学术圈发文曝光了svc-develop-team的问题

虽然svc-develop-team的Rcell私聊本人达成和解，然而如NaruseMioShirakana等其他开发者，利用B站用户不懂代码、在B站带节奏造谣

VI-SVC

how to clone your voice

use base model and your voice data to fine tune, just voice data（speech or song） without lables.
