字典中缺少单词时的异常

Question

我尝试了演示应用程序，它运行良好，但是当我尝试集成我自己的 .jsgf 语法文件时，当我尝试使用 .lm 文件对同一词典进行同样的操作时它运行良好时出现错误。

我提到了 PocketSphinx android demo runtime exception link 但它没有帮助我

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);
    }

错误如下

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

我还意识到我正在使用的任何 .jsgf 语法文件都没有检测到字典中的最后一个单词。在我更改为我自己的 .jsgf 语法文件后它工作正常之前它给出了异常

Answer 1

这一行：

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

告诉您需要将单词 'next' 添加到词典中。你在你的 JSGF 语法中使用了这个词，但它在字典中不见了。单词是 case-sensitive，因此您需要确保使用正确的大小写。

Answer 2

我可能知道你的问题。您必须以正确的形式编写语法，例如 space 和制表符。我建议您检查块或制表符的语法。对不起我糟糕的英语。
