Question

我尝试了演示应用程序，它运行正常，但是当我尝试集成我自己的.jsgf语法文件时，当我尝试使用同一字典的.lm文件进行同样的操作时，它会出错。

我提到PocketSphinx android demo runtime exception链接，但它没有帮助我

以下是代码段：

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

此外，我意识到我使用它的任何.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语法文件之后它正常工作之前它正在提供异常

Answer 1

这一行：

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

告诉您需要添加＆＃39; next＆＃39;到字典。你在JSGF语法中使用了这个词，但字典中却没有。单词区分大小写，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。你必须以正确的形式制作语法，比如你的空格和制表符。我建议你检查你的语法块或标签。对不起，我的英语很差。
