Who taught it that?

I use the Google Maps app for satnav these days, and there's something quite interesting about the way it directs you to Alvecote. It doesn't get everything right - No Man's Heath becomes 'No Man's Health' which is marginally amusing.

When directing you down Alvecote Lane, it pronounces it as it's spelt. But when it says Alvecote Marina, it pronounces it the old boatman's way: 'Awcutt'. Someone must have taught it this. How does that work?
