The altitude call outs are from the TAWS terrain warning system and are heard on every landing. They are the height above the ground based on the radar altimeter. The calls are "100... 50... 30... 20... 10". If an ILS is not in use you will also get a call at "500". There may be some minor differences between different aircraft types.

I agree with all this. The cavalry charge is designed and intended to be quite unmissable.

But I'm a little puzzled by the "female voice whose words I could not make out". I wonder if it might have been a GPWS glideslope or sink rate call, or something like that?
