In the Embraer 145 series you press the 'T/O Config' button and she says 'Takeoff OK' if you're configured.
If you forgot, say, the flaps -she says 'Take off FLAPS'
Very safe system.
On some a/c you press the button and get silence if you are correctly configured. You also get silence if the T/O config system is u/s, which is what happened to the MD at MAD. Not as safe, but still very common.
