• receiving input speech from a user;
• converting, via a processor, only the input speech corresponding to single digits into a string of words, wherein each word in the string of words is modeled using a three segment word structure comprising a plurality of heads and a plurality of tails;
• converting the string of words into a sequence of digits using classes of rules;
• comparing the sequence of digits to a plurality of valid sequences of digits, to yield validity information;
• and
• providing the validity information to a device associated with the user.
