android pocketshpinx“字典中缺少单词 %s”错误

Question

我正在尝试使用这个袖珍 sphinx android 库在片段中测试一些基本的关键字识别。我已设置项目 jar 并正确添加为依赖项，我已按照本教程中的说明将 .so 文件添加到 jniLibs 文件夹 http://cmusphinx.sourceforge.net/wiki/tutorialandroid

就其他搜索（数字等）而言，一切似乎都很好。但由于某种原因，我无法让关键字搜索工作。我遇到了一个非常清晰和明确的错误消息。基本上就是说一堆词在字典里找不到。

我正在使用库附带的字典“cmu-en-us.dict”，实际上它似乎根本没有包含这些大写单词。

然后我四处寻找，找到了这个 http://svn.code.sf.net/p/cmusphinx/code/trunk/cmudict/cmudict-0.7b

当我将它添加到项目中并尝试引用该字典时。我遇到了与以前相同的错误，但现在说我使用的 previous 字典中的单词（cmu-en-us.dict）丢失了。

我不确定我做错了什么。但是我只是按照设置教程进行操作，并且还使用了演示项目的 Activity 中的代码 https://github.com/cmusphinx/pocketsphinx-android-demo/blob/master/app/src/main/java/edu/cmu/pocketsphinx/demo/PocketSphinxActivity.java

哦，这就是我设置 SpeechRecognizer 的方法

private void setupRecognizer(File assetsDir) throws IOException {
    // The recognizer can be configured to perform multiple searches
    // of different kind and switch between them
    Log.d("RecipeSearchFragment", "setupRecognizer");
    mRecognizer = defaultSetup()
            .setAcousticModel(new File(assetsDir, "en-us-ptm"))
            .setDictionary(new File(assetsDir, "cmudict-en-us.dict"))


                    // To disable logging of raw audio comment out this call (takes a lot of space on the device)
            .setRawLogDir(assetsDir)

                    // Threshold to tune for keyphrase to balance between false alarms and misses
            .setKeywordThreshold(1e-45f)

                    // Use context-independent phonetic search, context-dependent is too slow for mobile
            .setBoolean("-allphone_ci", true)

            .getRecognizer();
    mRecognizer.addListener(this);

    /** In your application you might not need to add all those searches.
     * They are added here for demonstration. You can leave just one.
     */


    mRecognizer.addKeywordSearch(KWS_SEARCH, new File(assetsDir, "cmudict-en-us.dict"));

    mRecognizer.startListening(KWS_SEARCH);

}

还有其他人遇到过这种情况吗？我在这里做错了什么？

Answer 1

关键字搜索配置有关键字列表文件。关键词列表文件每行列出一个关键词：

Recognizing multiple keywords using PocketSphinx

您在以下行中错误地将字典用作关键字列表文件：

mRecognizer.addKeywordSearch(KWS_SEARCH, new File(assetsDir, "cmudict-en-us.dict"));

这不是一个好主意。
