PURPOSE: An apparatus and a method for retrieving wireless Internet information using a mobile communication terminal are provided to receive a retrieval word as a voice signal form from a user, retrieve corresponding information, and output the retrieved result as the voice signal form. CONSTITUTION: A mobile communication terminal receives a retrieval word with a voice signal form and transmits the corresponding retrieval word to a server(206). A gateway extracts the start and end of the retrieval word voice signal transmitted from the mobile communication terminal(208), extracts the feature of the voice(210), and performs a linear estimation predictive analysis(212) and a comparison/approximation calculation(214). The gateway retrieves a corresponding word from a word database of the server, and extracts the retrieved word(216). The server retrieves corresponding information through the extracted retrieval word(218), converts corresponding information into a voice signal(220), and transmits the voice signal to a switch or CTI(Computer Telephony Integration). The switch or CTI transmits the corresponding voice signal to the mobile communication terminal through a wireless interval(222). The mobile communication terminal receives the voice signal transmitted through the switch, and outputs the received voice signal through a speaker so that a user obtains corresponding information(224).
