CMUSphinx从不识别音频文件中的任何单词
kevinn2065
Sphinx似乎无法识别或处理音频文件，它接受音频流后会吐出一个空数组（SpeechResult结果）。我觉得我正在使用的音频文件没有任何问题，因为我已经尝试了几次，但对任何一个都不起作用。有人有一个他们知道有效的音频文件吗？并且有什么引人注目的可能导致流不产生转录的东西吗？
public static void main(String args[]) throws IOException {
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");
StreamSpeechRecognizer recognizer = new StreamSpeechRecognizer(configuration);
//recognizer.startRecognition(new FileInputStream("E:/1video/hello-5.mp3"));
File file = new File("E:/1video/bargain_not.wav");
FileInputStream fis = new FileInputStream(file);
InputStream is = new FileInputStream(file);
//is = AutomaticSpeechRecognition.class.getResourceAsStream("/edu/cmu/sphinx/demo/aligner/10001-90210-01803.wav");
recognizer.startRecognition(is);
SpeechResult result = null;
while((result = recognizer.getResult()) != null) {
System.out.println(result.getResult());
System.out.println(result.getHypothesis());
System.out.println(result.getWords());
}
//result = recognizer.getResult();
//System.out.println(result);
//System.out.println(result.toString());
//System.out.println(result.getWords());
/*for (WordResult wordResult : result.getWords())
{
System.out.println(wordResult);
}*/
recognizer.stopRecognition();
}
这是运行它的输出-它似乎没有任何故障

像Nikolay Shmyrev所说的文件必须是16khz 16bit mono MSWAV。这样的文件可以用Audacity录制。
文件导出，并确保选择WAV（Microsoft）签名的16位PCM。
