Circuit to detect when LED stops flashing

I have a battery charger that displays a flashing LED when charging a battery. When charging is complete the LED stops flashing and stays on in a constant state. I need a circuit to detect this change from flashing to constant on so that I can
use it to trigger an audible alert. Any suggestions??
