我想創建一個識別文件.wav中的語音的程序。我想下面的代碼，但它拋出一個異常帶自定義配置的Sphinx4 OutOfMemoryError
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded
即使我的「的eclipse.ini」有這樣的屬性：
--launcher.XXMaxPermSize 2048M
--launcher.XXMaxPermSize 2048m
-Xms2048m
-Xmx2048m
我怎樣才能解決這個例外？
Java代碼：
import java.net.MalformedURLException;
import java.net.URL;
import edu.cmu.sphinx.frontend.util.AudioFileDataSource;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
import edu.cmu.sphinx.util.props.ConfigurationManager;
public class TestRecognizer {
public static void main(String[] args) {
ConfigurationManager cm;
if (args.length > 0) {
cm = new ConfigurationManager(args[0]);
} else {
cm = new ConfigurationManager("english_use_LexTreeLinguist.xml");
}
URL audioURL = null;
try {
audioURL = new URL("file:./10001-90210-01803.wav");
} catch (MalformedURLException e) {
e.printStackTrace();
}
if(audioURL == null)
throw new IllegalArgumentException("Given audio file doesn't exist.");
// allocate the recognizer
System.out.println("Loading recognizer");
Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
recognizer.allocate();
System.out.println("Loading audio");
AudioFileDataSource dataSource = (AudioFileDataSource) cm.lookup("audioFileDataSource");
dataSource.setAudioFile(audioURL, null);
// loop the recognition until the programm exits.
Result result;
System.out.println("recognizing");`enter code here`
while ((result = recognizer.recognize())!= null) {
String resultText = result.getBestResultNoFiller();
System.out.println(resultText);
}
}
}
