recording sound recognize android

Question

I develop an app where the user can record an sound, maybe a clap or other sounds. The android system should save it, since the user delete the command. With that recording sound the user can select any commands that the device maybe show an intent or others. Now my question: Is it possible that when the microphone are on that the device when it hear the recording voice start the intent and when it is possible how can I do that? I think that I maybe do it with getMaxAmplitude() but I need an method to decide the length of that amplitude.
