使用没有Maven的sphinx4 jar时出错

Question

我有API Sphinx4的问题,我无法弄清楚为什么它不起作用.

我尝试写一个小类来捕获用户的声音并在文件上写下他的发言.

1)我在Eclispe上创建了一个新的java项目.

2)我创建了TranscriberDemo类.

3)我创建了一个文件夹"file".

4)我在文件夹"file"上复制文件夹"en-us"和文件"cmudict-en-us.dict","en-us.lm.dmp","10001-90210-01803.wav" .

5)我不使用maven,所以我只包含jar文件"sphinx4-core-1.0-SNAPSHOT.jar"和"sphinx4-data-1.0-SNAPSHOT.jar".

你可以在这里下载它们:

数据:https://1fichier.com/？lpzz8jyerv

我知道源代码可用

这里:https://github.com/erka/sphinx-java-api

或者在这里:http://sourceforge.net/projects/cmusphinx/files/sphinx4

但我不使用maven所以我无法编译它们.

我的课:

import java.io.InputStream;

import edu.cmu.sphinx.api.Configuration;
import edu.cmu.sphinx.api.SpeechResult;
import edu.cmu.sphinx.api.StreamSpeechRecognizer;
import edu.cmu.sphinx.result.WordResult;


public class TranscriberDemo
{
    public static void main(String[] args) throws Exception
    {
        System.out.println("Loading models...");

        Configuration configuration = new Configuration();

        // Load model from the jar
        configuration.setAcousticModelPath("file:en-us");

        configuration.setDictionaryPath("file:cmudict-en-us.dict");
        configuration.setLanguageModelPath("file:en-us.lm.dmp");

        StreamSpeechRecognizer recognizer = new StreamSpeechRecognizer(configuration);
        InputStream stream = TranscriberDemo.class.getResourceAsStream("file:10001-90210-01803.wav");
        stream.skip(44);

        // Simple recognition with generic model
        recognizer.startRecognition(stream);
        SpeechResult result;
        while ((result = recognizer.getResult()) != null)
        {
            System.out.format("Hypothesis: %s\n", result.getHypothesis());

            System.out.println("List of recognized words and their times:");
            for (WordResult r : result.getWords())
            {
                System.out.println(r);
            }

            System.out.println("Best 3 hypothesis:");
            for (String s : result.getNbest(3))
                System.out.println(s);
        }
        recognizer.stopRecognition();
    }
}

Answer 1

您的代码和操作存在多个问题:

3)我创建了一个文件夹"file".

不需要

4)我在文件夹"file"上复制文件夹"en-us"和文件"cmudict-en-us.dict","en-us.lm.dmp","10001-90210-01803.wav" .

不需要,您已经将模型作为sphinx4数据包的一部分.

5)我不使用maven,所以我只包含jar文件"sphinx4-core-1.0-SNAPSHOT.jar"和"sphinx4-data-1.0-SNAPSHOT.jar".

这是非常错误的,因为你从未经授权的位置拿走了过时的罐子.下载罐子的正确位置列在教程http://oss.sonatype.org中

https://oss.sonatype.org/service/local/repositories/snapshots/content/edu/cmu/sphinx/sphinx4-core/1.0-SNAPSHOT/sphinx4-core-1.0-20150223.210646-7.jar

https://oss.sonatype.org/service/local/repositories/snapshots/content/edu/cmu/sphinx/sphinx4-data/1.0-SNAPSHOT/sphinx4-data-1.0-20150223.210601-7.jar

你从一些可能含有病毒或rootkit的随机网站中获取了恶意罐子.

这里:https://github.com/erka/sphinx-java-api

这也是一个错误的链接.正确的链接是http://github.com/cmusphinx/sphinx4

    InputStream stream = TranscriberDemo.class.getResourceAsStream("file:10001-90210-01803.wav");

在这里,您使用file:URL scheme指向不适合上下文中的文件.如果你想从文件创建InputStream,请执行以下操作:

 InputStream stream = new FileInputStream(new File("10001-90210-01803.wav"));

线程"main"中的异常java.lang.NoClassDefFoundError:com/google/common/base/Function

这个错误是由你从其他地方带来一个jar的事实引起的,它说你需要额外的依赖.当您看到ClassDefFoundError时,这意味着您需要在类路径中添加额外的jar.使用官方sphinx4,你不应该看到这个错误.

Answer 2

解决了.

事实上这是一个愚蠢的错误......

谢谢@Nikolay的回答.我已经接受了你的回答,但我在这里恢复了这个过程:

1)从https://oss.sonatype.org/#nexus-search;quick~sphinx4下载sphinx4-core和sphinx4-data jar .

2)将它们包含在您的项目中.

3)测试你的代码.

import edu.cmu.sphinx.api.Configuration;
import edu.cmu.sphinx.api.LiveSpeechRecognizer;
import edu.cmu.sphinx.api.SpeechResult;

public class SpeechToText
{
    public static void main(String[] args) throws Exception
    {
        Configuration configuration = new Configuration();
        configuration.setAcousticModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us");
        configuration.setDictionaryPath("resource:/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict");
        configuration.setLanguageModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us.lm.dmp");

        LiveSpeechRecognizer recognizer = new LiveSpeechRecognizer(configuration);
        recognizer.startRecognition(true);

        SpeechResult result;
        while ((result = recognizer.getResult()) != null)
        {
            System.out.println(result.getHypothesis());
        }
        recognizer.stopRecognition();
    }
}

这就是全部!
