I wonder if mcdonalds records/retains the audio from its drive through systems. Seems like a goldmine of validation data thats already labelled (with the order the employee entered).

Voice with some minor interaction seems like a much better solution for the kiosks as well. "Large Big mac meal" is a lot quicker than clicking through a kiosk.

Unless the technology has improved I would say that most systems are not much better than a CB radio.

The external microphones can be subject to a lot of wear and tear, external noise. I haven't any knowledge of a system as sophisticated as recording voice and storing, let alone pairing an audio segment to data on the pos. But rightly identified as a perfect opportunity to label training data, and you wouldn't think it would be too hard to deploy, at least in a limited capacity for the initial training and validation on this project.

I imagine some old systems from before the dawn of big data don't.
