If I were McDonald’s, I would have long ago installed microphones at the cash registers and trained a speech recognition system while still in the learning mode. This would allow accumulating more data and periodically checking the quality of recognition. In a year, cashiers could be kept just to confirm 80% of the orders, and in five years, cashiers might not be needed at all. If anyone says that five years is a lot, remember how different a McDonald’s from five years ago was from the current one, except for the terminals.
