description = """
This synthesizer is created based on VITS (https://arxiv.org/abs/2106.06103) model, trained on voice data extracted from mobile game Umamusume Pretty Derby\n
这个合成器是基于VITS文本到语音模型，在从手游《賽馬娘：Pretty Derby》解包的语音数据上训练得到。\n
If your input language is not Japanese, it will be translated to Japanese by Google translator, but accuracy is not guaranteed.\n
如果您的输入语言不是日语，则会由谷歌翻译自动翻译为日语，但是准确性不能保证。\n\n
若使用人数太多可能会出现排队过久的情况，若有需要可选择本地部署
