Listen for more words

[JuLoOr]

Hello guys,

i tried the ps-android demo and it works perfekt for me.
Now I want to listen for more keywords. How can i do that?

My present code:

public class MainActivity extends Activity implements RecognitionListener {

private SpeechRecognizer recognizer;

private static final String KWS_SEARCH = "wakeup";
private static final String KEYPHRASE = "test";
TextView tv;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    tv = (TextView) findViewById(R.id.tv);

    new AsyncTask<Void, Void, Exception>() {
        @Override
        protected Exception doInBackground(Void... params) {
            try {
                Assets assets = new Assets(MainActivity.this);
                File assetDir = assets.syncAssets();

                setupRecognizer(assetDir);
            } catch (IOException e) {
                return e;
            }
            return null;
        }

        @Override
        protected void onPostExecute(Exception result) {
            if (result != null) {
                Log.d("Recognizer", result.toString());
            } else {
                startSearch(KWS_SEARCH);
            }
        }
    }.execute();

}

private void setupRecognizer(File assetDir) {
    File modelsDir = new File(assetDir, "models");
    recognizer = defaultSetup()
            .setAcousticModel(new File(modelsDir, "hmm/en-us-semi"))
            .setDictionary(new File(modelsDir, "dict/cmu07a.dic"))
            .setRawLogDir(assetDir).setKeywordThreshold(1e-20f)
            .getRecognizer();
    recognizer.addListener(this);

    recognizer.addKeyphraseSearch(KWS_SEARCH, KEYPHRASE);

}

@Override
public void onPartialResult(Hypothesis hypothesis) {
    String text = hypothesis.getHypstr();

    tv.setText(text);

    recognizer.stop();
    recognizer.startListening(KWS_SEARCH);
}

private void startSearch(String searchName) {
    // recognizer.stop();
    recognizer.startListening(searchName);
}

Best regards Jul

SpeechRecognizer#addKeywordSearch(String name, File file). The file should contain keyphrases, one per line.

How can I add my commands.txt file to assets/sync/.. ?

I thought adding to models dir is enough, but i need a md5?

Just put the file in the folder

MD5 is created automatically with a custom builder. You need to have Java Development installed in Eclipse and make sure that custom builder is properly imported when you import the project.

See for details

Does not work:

recognizer.addKeywordSearch(KWS_SEARCH, new File(modelsDir, "commands.txt"));

Log:
08-19 18:46:38.577: E/cmusphinx(26396): ERROR: "kws_search.c", line 349: Failed to open keyword file '/storage/emulated/0/Android/data/com.example.keywordrecognition/files/sync/models/commands.txt': No such file or directory

Just checked my sd-card, there is no commands.txt

Ok just found my mistake. You were right, I built the first time with the custom builder, but now it's gone. Can i add it afterwards?

Check this:

Or, simple way, copy .externalToolBuilders folder and assets.xml from Pocketsphinx Android Demo project to your project.
