FOR ANDROID DEVELOPMENT

  1. You can always make photo and send it out to images google, also you should be able to record GPS coordinates and place marker on the map. I would not be surprised if Google Maps managed something as image search instead of simple location name search. Someone may provide more detailed answer, because I have no experiences with it. Nevertheless do research
  2. Speech recognition already have API http://developer.android.com/reference/android/speech/package-summary.html
  3. Same for text to speech http://developer.android.com/reference/android/speech/tts/TextToSpeech.html
