Android: PocketSphinx speech/voice recognition library in background.

As you know we have Google Voice for voice recognition.

Here is simple way to implement offline speech recognition using PocketSphinx lib.

I’ve created simple app which will run Service with speech recognition functionality.

You can add one keyword here:

recognizer.addKeyphraseSearch(KWS_SEARCH, KEYPHRASE);

Sure PocketSphinx have multi-keyword functionality.

File menuGrammar = new File(assetsDir, "voicecommands.gram");
recognizer.addGrammarSearch(VOICE_COMMAND, menuGrammar);

But for me it is’t perfect.

One-word mode works better.

Use PocketSphinx if you need only one-keyphrase recognition.
