嘗試Sphinx4時IndexOutOfBound

我創建了Sphinx4（語言模型，字典和聲學模型）所需的所有模型。我在Eclipse中創建了一個Maven項目並下載了所有的庫，但是當我運行程序（如官方網站所示）時，會出現一個異常。嘗試Sphinx4時IndexOutOfBound

，我正在運行的源代碼如下：

import java.io.File; 
import java.io.FileInputStream; 
import java.io.FileNotFoundException; 
import java.io.IOException; 
import java.io.InputStream; 

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

public class Main { 

public static void main(String[] args) { 

    Configuration configuration = new Configuration(); 

    configuration.setAcousticModelPath("Alphabets/acoustic"); 

    configuration.setDictionaryPath("Alphabets/alphabets.dic"); 

    configuration.setLanguageModelPath("Alphabets/alphabets.lm.dmp"); 

    LiveSpeechRecognizer recognizer = null; 
    try { 
     recognizer = new LiveSpeechRecognizer(configuration); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    recognizer.startRecognition(true); 
    SpeechResult result = recognizer.getResult(); 
    recognizer.stopRecognition(); 

    System.out.println(result.getHypothesis()); 
    result.getLattice().dumpDot("lattice.dot", "lattice"); 

    } 
}

我高度讚賞援助。

您正在嘗試將sphinx4與半連續模型一起使用。你需要訓練連續模型sphinx4使用，詳見

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

您需要設置

$CFG_HMM_TYPE = '.cont.'; # Sphinx 4, Pocketsphinx

連續和半連續式兩種類型的CMUSphinx支持的聲學模型。它們不同於模型的內部結構。連續模型更精確，半連續模型更快，更緊湊，但不夠精確。 Sphinx4僅支持連續模式。 Pocketsphinx支持連續和半連續模式。 – 2014-09-02 18:02:34

非常感謝，但是如果您可以詳細說明可以設置上述參數的文件？ – coding4fun 2014-09-02 18:04:20

當您訓練聲學模型時，在etc/sphinx_train.cfg中。 – 2014-09-02 18:06:58
