An apparatus for restricting access to a telephone call management system, said apparatus comprising:

• a registration module configured to, during a registration process by a user of said telephone call management system, prompt said user to speak one or more predetermined keywords and receive a first speech sample from said user;
• a database including said first speech sample associated with said user;
• a prompting module configured to prompt said user to provide a second speech sample when said user subsequently attempts to access said telephone call management system;
• a speaker independent voice recognition module configured to verify said first speech sample is indicative of said one or more predetermined keywords;
• and
• a speaker dependent voice identification module configured to determine whether a voice characteristic of said second speech sample matches a voice characteristic of said first speech sample,
• wherein said telephone call management system authorizes said user to complete a telephone call using said telephone call management system when a voice characteristic of said second speech sample matches a voice characteristic of said first speech sample, and
• wherein said telephone call management system, after authorizing said user to use said telephone management system, samples voice data from said telephone call to detect if an unauthorized person has spoken based on the voice characteristic of the verified first speech sample.
