voice activated flashing led

I have an idea for a project for my deaf daughter but I need a circuit that triggers some flashing LED when she talks and need some help with the circuit. I've seen similar ideas for hoking up to speakers but I need something with a mic that is a bit more sensitive.

Thanks

Hi Taise,

That actually sounds like a pretty interesting project. Should the LED simply be on when sound is detected and off when no sound is detected....or is there an expectation that the LED would be brighter or darker when sounds are louder and softer?

Let me know and I'll hit the drawing boards.
