字典中缺少单词时出现异常

Question

我尝试了演示应用程序，它运行良好，但当我尝试集成我自己的.jsgf语法文件时，当我为同一词典使用.lm文件时，它出现了错误，运行良好。

我提到了PocketSphinx android演示运行时异常链接，但它对我的没有帮助

以下是代码片段：

private void setupRecognizer(File assetsDir) throws IOException {
        // The recognizer can be configured to perform multiple searches
        // of different kind and switch between them
        File modelsDir = new File(assetsDir, "models");
        mRecognizer = defaultSetup()
                .setAcousticModel(new File(assetsDir, "en-us-ptm"))
                .setDictionary(new File(assetsDir, "cmudict-en-us.dict"))
                .setRawLogDir(assetsDir)
                .setKeywordThreshold(1e-10f)
                .setFloat("-beam", 1e-30f)
                .setBoolean("-allphone_ci", true)
                .getRecognizer();
        mRecognizer.addListener(this);
        File languageModel = new File(assetsDir, "commands_gram.gram");
        mRecognizer.addGrammarSearch(COMMANDS, languageModel);
    }

以下是错误

我还意识到，我使用的任何.jsgf语法文件都不会检测到字典中的最后一个单词。在我更改为自己的.jsgf语法文件后，它还没有正常工作，它给出了异常

Answer 1

此行：

E/cmusphinx: ERROR: "fsg_search.c", line 141: The word 'next' is missing in the dictionary 

告诉你需要把单词"next"加到字典里。你在JSGF语法中使用了这个词，但字典里没有这个词。单词区分大小写，所以你需要确保使用正确的大小写。

我可能知道你的问题。你必须把语法做成正确的形式，比如空格和制表符。我建议你检查一下你的语法是块还是制表符。对不起，我英语不好。
