不知道从哪些类开始测试 sphinx4

Question

我已经完成了这些步骤

1- 从https://sourceforge.net/projects/cmusphinx/files/sphinx4/5prealpha/下载最新版本的Sphinx4

2- 在 Eclipse（Gradle 插件）中安装 Gradle IDE Pack 3.8.x + 1.0.x。

3- 将 Sphinx4 作为 Gradle STS 项目导入。

现在我得到了如下图所示的错误

由于时间原因，我已经评论了这些错误，因为我不知道为什么会出现这些错误。

现在我想运行 Sphinx4，但我不知道要运行什么以及如何运行。 我在谷歌上尽了最大的努力，并尝试了好几天。但没有得到积极的结果。

如果有人可以帮助我解决问题并指导我如何将 sphinx4 作为 gradle 运行，那就太好了。如您所见，sphinx 有 4 个项目，所以要运行哪个项目。

问“如果我成功运行会输出什么”可能很愚蠢

PS：我是 Gradle 和 Sphinx4 的新手 也看过this link

Answer 1

教程says

sphinx4 源代码中包含许多示例演示，以便让您了解如何运行 Sphinx4。您可以从 sphinx4-samples jar 中运行它们：

• Transcriber - 演示如何转录文件
• Dialog - 演示如何与用户进行对话
• SpeakerID - 说话人识别
• Aligner - 音频到转录时间戳的演示

您只需要仔细阅读即可。

虽然我将 jars 添加到类路径中的方式不同，但它会为你工作。

出现这些错误是因为您的编码设置不正确。
