Java 文语转换器

我使用文本到语音转换器api将文本转换为另一种语言。我将gtranslateapi-1.0.jar和jl-1.0.jar文件添加到库路径中。这是我的代码片段

public class NextTranslator {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Translator translate = Translator.getInstance();
        String text = translate.translate("I am programmer", Language.ENGLISH, Language.PORTUGUESE);
        System.out.println(text);
        /*  Translator translate = Translator.getInstance();
         String prefix = translate.detect("I am a bus");
         System.out.println(prefix);*/
    }

}

作为输出，我得到以下错误

java.net.UnknownHostException: translate.google.com.br

这意味着我需要我知道的钥匙。这意味着我不能在没有键的情况下使用文本到语音的api吗

据说这个api是免费的。我是否可以在java web应用程序中免费使用文本转换器？

您的API显然需要连接到translate.google.com.br才能工作，但您的java程序找不到主机，这意味着您的DNS服务器存在连接问题。请尝试在您的开发计算机上ping此主机。我已更新了。请检查问题并帮助我查找和回答。谢谢您。一个“免费”API可能需要注册。将其视为一项服务。他们给你一个60天的试用期：“你免费注册，在60天内花300美元在所有谷歌云平台服务上。”
