Answer 1

Yes, you need to use createSpeechRecognizer(Context context, ComponentName serviceComponent)

Answer 2

If you want queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0) to pick up your activity (VoiceServiceStarterActivity) then you have to declare in your app's Manifest that this activity handles RecognizerIntent.ACTION_RECOGNIZE_SPEECH, like this

<activity android:name="VoiceServiceStarterActivity">
  <intent-filter>
    <action android:name="android.speech.action.RECOGNIZE_SPEECH" />
    <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>
  ...
</activity>

For more concrete code have a look at the project Kõnele (source code) which is essentially an open source implementation of the interfaces via which speech recognition is provided on Android, i.e. it covers:

• ACTION_RECOGNIZE_SPEECH
• ACTION_WEB_SEARCH
• RecognitionService

and uses open source speech recognition servers.
