                    如果你选择语言为\'mix\'，必须按照格式输入，否则报错:
                        格式举例(zh是中文，jp是日语，不区分大小写；说话人举例:gongzi):
                         [说话人1]<zh>你好，こんにちは！ <jp>こんにちは，世界。
                         [说话人2]<zh>你好吗？<jp>元気ですか？
                         [说话人3]<zh>谢谢。<jp>どういたしまして。
                         ...
                    另外，所有的语言选项都可以用'|'分割长段实现分句生成。
