使用Sphinx4进行听写应用 [英] Dictation Application using Sphinx4
本文介绍了使用Sphinx4进行听写应用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的要求类似于此问题，因为问题现在已经3岁了，我要重新发布该问题，并附带我的特定信息，我想创建一个应用程序，该应用程序使用.wav(或任何其他标准音频文件格式)并将其转换为文本.
My requirements are similar to this question since the question is now 3 years old I am re-posting the question with information specific to mine, I want to create an application which takes a .wav (or any other standard audio file format) and converts it to text.
对于语音识别，我决定使用sphinx4，我正在尝试增强sphinx随附的Transcriber演示.它很好，但是仅适用于特定的语法(以.gram和.gxml文件编写).
For Speech Recognition I have decided to use sphinx4, I am trying to enhance the Transcriber demo provided with sphinx. Its good but That only works for a specific Grammar (written in .gram and .gxml files).
编辑 能够与英语一起使用吗?我正在尝试使用VoxForge_en_0.4对其进行配置.我的config.XML文件看起来像:-
EDIT To be able to use it with English ? I am trying to configure it with VoxForge_en_0.4. My config.XML file looks like:-
<?xml version="1.0" encoding="UTF-8"?>

在哪里可以获取Sphinx4可以使用的美国英语语言模型?
Where do I get the language model for US English that can be used with Sphinx4 ?
您可以从CMUSphinx网站和其他地方下载它们.您也可以自己构建它们.可能的位置之一是
You can download them from CMUSphinx website and from other places. You can also build them yourself. One of the possible locations are

Any blog / tutorial will be helpful,
见上文
尽管本教程中使用的文件具有不同的扩展名，但我仍处于这一阶段，无法确定应在配置中指定哪个路径.请帮助，
However the files used in this tutorial are of differrent extensions, I am stuck in this phase I cant decide which path should be given in configuration. Plz Help,
请参阅sphinx4/tests/performance/voxforge_en/voxforge.config.xml中的示例配置.它具有所有必需的路径
See the example config in sphinx4/tests/performance/voxforge_en/voxforge.config.xml. It has all required paths
这篇关于使用Sphinx4进行听写应用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
