1. A voice log-in method for logging in to a system based on computerized recognition of a spoken name input comprising the steps:

  • creating an augmented name recognition model from the spoken name input for each person to be enrolled, wherein said augmented name recognition model includes constituent name-part utterances, and also includes any pause in the spoken name input, and wherein said augmented name recognition model represents a portion of said constituent name-part utterances as optional, thereby accommodating elimination of optional name-part utterances, and wherein said pause is also represented as optional, thereby accommodating unpredictable variations in said pause, and wherein said creating name recognition models is accomplished using HMM (Hidden Markov Modeling) to create HMM name recognition models;

    storing said name recognition model for each person enrolled in a name recognition model database;

    comparing the spoken name input with the stored name recognition models each time a person seeks access to the system by voice log-in; and

    logging a person in to the system if a pattern match is found, during said comparing, between the spoken name input and one of the stored name recognition models.
