Yes, it is a womans voice that responds, when you use the Bluetooth commands.
In your SEAT Wallet you should have got with the car, there is a "Communications Booklet" that gives all the commands you can use for Bluetooth. "Dial Name", "Dial Number" etc....
You first press the button on the steering wheel with the picture of a face speaking (on the left side). Then you speak your commands to make calls. "She" talks back to confirm the commands you have given.
Would be cool if the womans voice could be changed, like you can do with good GPS units.
