How to query for the default SpeechRecognizer

Question

How to find out the ComponentName of the default system speech recognizer, i.e. the one that is returned when createSpeechRecognizer(Context context) is called? (Actually, I only need to find out which input languages it supports, so if there is an answer only to that, then I'd appreciate it as well.)

The framework solves this by

String serviceComponent = Settings.Secure.getString(mContext.getContentResolver(),
                        Settings.Secure.VOICE_RECOGNITION_SERVICE);

(See the source code of SpeechRecognizer.)

However, this solution does not seem to be available to a third party app.

However, this solution does not seem to be available to a third party app.

I assume you came to such conclusion because Settings.Secure.VOICE_RECOGNITION_SERVICE is not a public API. However, Settings.Secure.getString() requires name of the row to lookup in secure table for the second argument. So, you can simply provide the actual the name of the row you are looking for: "voice_recognition_service".

That's, you can use the same code from SpeechRecognizer with slight change:

String serviceComponent = Settings.Secure.getString(mContext.getContentResolver(),
        "voice_recognition_service");

Hope this helps.
