I am training my PC to work on Voice Recognition .... with a Hampshire accent, 'cos I am the only one in the house with such an accent I figure it may be better than a password.
Once the PC has grasped the concept I plan to add in the famous Southampton Sniff. This is something peculiar to native So'tonians who end every statement with a sharp nasal inhale.
Top Tip: If they don't sniff at the end of a sentence they ain't natives.
