Method and apparatus for providing voice analyzing service on wire/wireless video communication network during video call

A method and an apparatus for providing a speech analysis service during a video call through a wired/wireless video call network are provided to extract and analyze a speech of a speaker in real time and supply the analysis result to a caller or a callee. An SG receives a first call set-up request signal from an originating terminal switch(207). In correspondence to the received first call set-up request signal, the SG transmits a second call set-up request signal to a receiving terminal switch(209). The SG receives a first call set-up answer signal from the receiving terminal switch(215). The SG transmits a second call set-up answer signal to the originating terminal switch(217). If a video call between a receiving terminal and an originating terminal is performed through a speech path formed by the first and second call set-up answer signals, an MG and an MS extract a voice from image/speech signals of the originating terminal or the receiving terminal and analyze the voice(221). The MS transmits the speech analysis result to one terminal of the originating terminal or the receiving terminal.
