There is some code that does exactly what you need here:

https://github.com/gast-lib/gast-lib/blob/master/library/src/root/gast/speech/activation/SpeechActivationService.java

See it running by downloading this app.

The code is a Service that runs in the background, listening for the users speech. When the user speaks a certain word, it fires an Intent. The Service also puts up a handy Notification while it is listening. There is some other code that starts and stops it here.
