Question

我的要求与this question类似，因为问题现在已经3年了，我正在重新发布有关我的特定信息的问题，我想创建一个带有.wav（或任何其他标准）的应用程序音频文件格式）并将其转换为文本。

对于语音识别我决定使用sphinx4，我正在尝试增强sphinx提供的Transcriber演示。它很好，但只适用于特定的语法（用.gram和.gxml文件编写）。

修改能用英语吗？我正在尝试使用VoxForge_en_0.4进行配置。我的config.XML文件如下所示： -

我的配置有什么问题吗？ Plz帮助......

Answer 1

对于语音识别我决定使用sphinx4，我正在尝试运行sphinx提供的Transcriber.jar演示。当我提供其他文件作为输入时，这不起作用。

如果你更好地描述你的问题，你可以在这个问题上得到更明确的帮助

我该怎么办？

阅读教程

http://cmusphinx.sourceforge.net/wiki/tutorial

我在哪里可以获得可与Sphinx4一起使用的美国英语语言模型？

您可以从CMUSphinx网站和其他地方下载它们。你也可以自己构建它们。其中一个可能的位置是

http://www.keithv.com/software/csr/

任何博客/教程都会有所帮助，

见上文

然而，本教程中使用的文件具有不同的扩展名，我陷入了这个阶段，我无法决定在配置中应该给出哪个路径。 Plz帮助，

请参阅sphinx4 / tests / performance / voxforge_en / voxforge.config.xml中的示例配置。它有所有必需的路径

使用Sphinx4的听写应用程序
