    These systems analyze the person's specific
    voice and use it to fine tune the recognition
    of that person's speech, resulting in more
    accurate transcription. Systems that do not

    systems.

    include voice user interfaces such as voice
    dialling (e.g., "Call home"), call routing
    (e.g., "I would like to make a collect
