无法启动服务？ （语音识别）

问题描述

我想在服务中连续使用口袋禅来听取hello这个词

我收到了错误消息。这是。这是它的一小部分。

I get the error. Here is the full stack trace. Here is a small portion of it.

Unable to create service curlybrace.ruchir.myApp.MyService: java.lang.RuntimeException: new_Decoder returned -1

这是由于：

            setupRecognizer(assetDir); //SETUP

and this：

                .getRecognizer();

在我的 onCreate ：

In my onCreate:

 Log.v(TAG, "Voice recognition activated!");

        //Register voice recog listener :)

        Assets assets = null;
        try {
            assets = new Assets(MyService.this);
            File assetDir = assets.syncAssets();
            setupRecognizer(assetDir); //SETUP

            Log.v(TAG, "Set up listener");
        } catch (IOException e) {
            e.printStackTrace();
        }

这是我的 setupRecognizer 方法：

Here is my setupRecognizer method:

  private void setupRecognizer(File assetDir) throws IOException {

        recognizer = defaultSetup()
                .setAcousticModel(new File(assetDir, "hmm/en-us-semi"))
                .setDictionary(new File(assetDir, "lm/cmu07a.dic"))
                .setKeywordThreshold(1e-5f)
                .getRecognizer();

        recognizer.addListener(this);
       // recognizer.addKeywordSearch("Hello", assetDir); //I don't know what this does...
    recognizer.startListening("Hello"); //Start listeneing


    }

这里是实施方法之一：

@Override
    public void onPartialResult(Hypothesis hypothesis) {

        String text = hypothesis.getHypstr();
        if (text.equals("Hello")) {
            //  do something

            Log.v(TAG, "SPEECH RECOGNIZED HELLO!");
        }

    }

我将不胜感激。积极的，消极的，甚至是评论。在这一点上，我在绝望之后，尝试了2天！

I would appreciate any feedback. Positive, negative, even a comment. At this point I am desperate, after trying for 2 days!

推荐答案

你有这个：

private void setupRecognizer(File assetDir) throws IOException {
        recognizer = defaultSetup()
                .setAcousticModel(new File(assetDir, "hmm/en-us-semi"))
                .setDictionary(new File(assetDir, "lm/cmu07a.dic"))
                .setKeywordThreshold(1e-5f)
                .getRecognizer();
        recognizer.addListener(this);
       // recognizer.addKeywordSearch("Hello", assetDir); //I don't know what this does...
    recognizer.startListening("Hello"); //Start listeneing
    }

尝试将其更改为：

private void setupRecognizer(File assetDir) throws IOException {
        recognizer = defaultSetup()
                .setAcousticModel(new File(assetDir, "hmm/en-us-semi"))
                .setDictionary(new File(assetDir, "lm/cmu07a.dic"))
                .setKeywordThreshold(1e-5f)
                .getRecognizer();
        recognizer.addListener(this);

    //Add this:
    File digitsGrammar = new File(modelsDir, "grammar/digits.gram");
    recognizer.addKeywordSearch(DIGITS_SEARCH, digitsGrammar);
    }

要开始语音侦听，请从按钮调用此方法。当它工作时，从服务中调用它，以使事情更简单：

To begin speech recon, call this from button. When it works, call it from a service, to keep things simpler:

    recognizer.startListening("Hello"); //Start listeneing

现在，创建一个名为digits.gram的新文件，并将其放在一个文件夹中在这里调用： /youProjectRootFolder/grammar/digits.gram
这个文件实际上是一个.txt文件，但是当你完成这个文件后，将扩展名更改为.gram里面的文字：

Now, create a new file called digits.gram, and put it inside a folder called here: /youProjectRootFolder/grammar/digits.gramThis file is really a .txt file, but change the extension to .gram when you are done putting this text inside:

hello /1e-1/
hi /1e-1/
bye /1e-1/
goodbye /1e-1/
...etc. /1e-1/

在这里你会发现类似的情况：
祝你好运！
