[citation][nom]jgutz2006[/nom]so one thing that people havent mentioned, is this give and go conversation. How is this going to work when you have 5 other carts and people nearby and theyre all talking ? Its like those "Pete the repeating parrot" once you push the button and say something, then push the button on 5 more, they keep repeating eachother over and over! Also will it be able to tell which of the 4 people in front of it are you and follow the correct person? will multiple carts in the same area be banging around? I like this tech but think that dropping the following cart gimmick. Maybe use as an app for people to have on their own devices[/citation]
Audio software can recognize voice patterns. If you intentionally speak in a very different way than you normally do then you could fool it, but different people's voices should only get mixed up if they have very similar voices.
Honestly, I don't care if I need to push a cart around or not. So long as it does checkout without me needing to go through actual checkout and such after waiting in lines I'll be much happier to go to a store when I need some more food and stuff.
