Today Class Tokens do not enforce grammar rules. Enforce API response to be aligned with a grammar rule match. Grammar rules can be regex-like.

Example 1: define a grammar rule to accept 6 digits, like “\d\d\d\d\d\d”
User says: eight eight ahhhh,, four two one three
API response: 884213 (API ignore “ahhhh”)

User says: eight eight four <inaudible> one three
API response: BLANK - API was not able to match 6 digits

Example 2: define a grammar rule to accept 2 letters, 3 digits and 1 letter, like “[A-Z][A-Z]\d\d\dL”
User says: P, O, zero eight ahhhh,, four W
API response: PO084W

User says: P, O, O (letter O, not zero) eight ahhhh,, four W
API response: PO084W (API understand that O should be converted to 0)

User says: zero eight ahhhh,, four W
API response: BLANK - user didn’t say “P O”

Example 3: define a grammar rule to accept 2 letters, 3 to 5 digits, like “[A-Z]{2}#{3,5}”
User says: P, O, zero eight four W
API response: PO884 (return matched case and ignore W)
