Do more with voice triggers using logical operators (e.g. AND/OR/NOT)?

Hi,

It would be great to have logical operators (AND/OR/NOT etc.) for voice triggers.

Usecase:

- Suppose your prototype asks your user what milkshake they'd like

- Suppose the flavours Strawberry, Chocolate and Banana are available

- Suppose the user responds (voice) with something else than these 3 flavors

- Suppose you want your prototype to respond "We don't have that, please choose between Strawberry, Chocolate or Banana"

The amount of "wrong" responses is infinite, so you cannot make a trigger for the whole dictionary. But what if:

You can combine voice triggers in an OR function:

trigger : voice

command : strawberry OR chocolate OR banana

voice response : coming up!

And cover all other scenarios in a NOT function:

trigger : voice

command : NOT strawberry NOT chocolate NOT banana

voice response : I did't get that, please choose between strawberry, chocolate and milkshake

Possibilities would be almost endless!!

BTW I wanted to share my prototype for this here, but there is no file upload...
