Question

我已经创建了Sphinx4所需的所有模型（语言模型，字典和声学模型）。我在Eclipse中创建了一个Maven项目并下载了所有库，但是当我运行官方网站（http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4）中显示的程序时， IndexOutOfBounds 异常被扔了。

我正在运行的源代码如下：

import edu.cmu.sphinx.api.Configuration;

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");

   }
}

我非常感谢您的帮助。

您正在尝试将sphinx4与半连续模型一起使用。您需要训练连续模型以与sphinx4一起使用，详见

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

您需要设置

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

尝试Sphinx4时的IndexOutOfBound
