添加新单词和.gram文件时出现Pocketsphinx错误

Question

我已经下载了Pocketsphinx演示版，但它运行正常。

我向cmudict-en-us.dict添加了新词并创建了新的

mobile.gram：

#JSGF V1.0;

grammar mobile;

public <companies> = stark | newline | uniqueshop;

在MainActivity.java中，我将天气识别替换为

// Create grammar-based search for company recognition
File mobileGrammar = new File(assetsDir, "mobile.gram");
recognizer.addGrammarSearch(MOBILE_SEARCH, mobileGrammar);

代码的其余部分在演示中更改，但我收到了错误

Caused by: java.lang.RuntimeException: Decoder_setJsgfFile returned -1

此错误指的是recognizer.addGrammarSearch(MOBILE_SEARCH, mobileGrammar);

menu.gram：

#JSGF V1.0;

grammar menu;

public <item> = digits | mobile | phones;

onPartialResult方法：

@Override
public void onPartialResult(Hypothesis hypothesis) {
    if (hypothesis == null)
        return;

    String text = hypothesis.getHypstr();
    if (text.equals(KEYPHRASE))
        switchSearch(MENU_SEARCH);
    else if (text.equals(DIGITS_SEARCH))
        switchSearch(DIGITS_SEARCH);
    else if (text.equals(PHONE_SEARCH))
        switchSearch(PHONE_SEARCH);
    else if (text.equals(MOBILE_SEARCH))
        switchSearch(MOBILE_SEARCH);
    else
        ((TextView) findViewById(R.id.result_text)).setText(text);
}
