1. A method of identifying a contact in a communication system using voice input, the method comprising: receiving an input string of characters, the input string representing a contact and being normally unpronounceable by a human voice when spoken literally; displaying, on a user terminal, a message that the input string is going to be transformed into a pronounceable name for the contact; performing at least one transforming step using the user terminal to transform at least one character of the input string to thereby generate the pronounceable name for the contact, the at least one transforming step being based at least in part on a region of the contact and performing regional sanitization based on the region to allow for cultural differences in the input string of characters by modifying the input string of characters to remove patterns of complexity and ambiguous string components; returning a result including a number of character changes and a number of characters removed during the at least one transforming step; and outputting the pronounceable name for use in establishing a communication event with the contact using voice input.
