android-java.lang.RuntimeException 中的 cmusphinx：Decoder_setKeyphrase 返回 -1

Question

我在 android 中使用 cmusphinx。首先，我执行了从 Github 下载的演示项目。当我建立自己的字典创建自己的 keyPhrase 时，它​​给出了以下 execption

这是我的 cmudict-en-us.dict 内容

 HELLO  HH AH L OW
 HELLO(2)   HH EH L OW
 HIMANSHU   HH AH M AE N SH UW

我将关键词设置为

private static final String KEYPHRASE = "hello himanshu";

Answer 1

单词区分大小写。你的关键词必须是大写的，就像字典里的一样。或者字典中的单词必须是小写的。音素必须大写。

要调试这样的错误，您可以阅读 logcat 输出，它提供有关问题的详细消息。
