First off all you need to recognize users speech by using Speech Recognizer. After that you'll receive a String with text. After getting from this text an app name you could get access to installed apps data and then launch an app you want by simple intent.

refer official documentation to start your activity using voice command.
This is for wearables, you can give it a try.
