Being able to verify or determine the identity of a person by voice is very useful in many applications. For example, in telephone banking or calling card charging, user identity must be verified before the transaction can be authorized. Most systems use a PIN for authorization, but it can be forgotten or stolen. Other methods of authorization, such as finger prints or retinal scans, may be more secure than a PIN, they are not practical in many situations.
