1. A combined mirror and presentation medium capable of speech recognition, comprising:

  • a presentation medium (20) comprising a presentation member (24) for displaying an image desired to be displayed, a presentation body (23) inserted and installed into the presentation member to display an image, a light-emitting unit (25) disposed on one side of the presentation member, a transparent member (21) disposed on one side of the presentation member, and a reflection member (22) deposited between the transparent member (21) and the presentation member (24);

    a body unit (10) for supporting the presentation medium;

    a speech recognition drive unit (40) installed inside the body unit (10), and configured to detect speech signals from a user, the speech recognition drive unit (40) comprising a microphone (41) for receiving presentation medium operating speech from the user and then generating speech signals, an amplification unit (42) for amplifying the speech signals received from the microphone (41) to a predetermined level, an Analog/Digital A/D conversion unit (43) for converting analog signals, that is, the speech signals received from the amplification unit (42) and amplified to a predetermined level, into digital signals, a speech interval extraction unit (44) for dividing the speech signals, which are received from the A/D conversion unit (43) and converted into the digital signals, into short unit signals, like syllables, and detecting only frames that correspond to actual speech from among frames obtained through the division, a feature extraction unit (45) for extracting speech features from the detected frames that are received from the extraction unit, and processing the extracted speech features into a test pattern signal, a pattern matching unit (46) for matching the test pattern signal, received from the feature extraction unit (45), to a signal stored in a reference pattern signal storage unit and extracting a corresponding reference pattern signal having a feature almost identical to the test pattern signal, and the speech recognition drive unit (40) configured to generate presentation medium operation function control signals in response to the corresponding reference pattern signal received from the pattern matching unit (46);

    a control unit (50) installed inside the body unit (10), and provided with an illumination control means (51) for causing the light-emitting unit (25) to emit light by combining speech signals acquired from the speech recognition drive unit (40), comparing the combined signal with previously input values and controlling the presentation medium based on a value of the comparison, thus controlling the speech recognition drive unit (40); and

    a power source unit (60) for supplying power to the presentation medium (20) and the control unit (50);

    wherein the combined mirror and presentation medium acts as a mirror so as to visually reflect an image of an oppositely located object at normal times, and brightens an inside of the presentation member by detecting speech signals from the user and controlling the illumination unit at a time of occurrence of the speech signals from the user, thus enabling display of the presentation body that is installed inside the presentation member.
