SPEAKER RECOGNITION METHOD AND SYSTEM USING WIRELESS MICROPHONE IN ROBOT SERVICE SYSTEM

摘要

A voice recognition method using a wireless microphone in an intelligent robot service system and an apparatus thereof are provided to enable a speaker having a wireless microphone transmitter to replace a VAD(Voice Activity Detection) function with only on/off of the wireless microphone, thereby operating the voice recognition system as necessary and speaking freely without considering a distance from a robot or a speaking position. A voice recognition method comprises the following steps of: registering speakers by using a wireless microphone(201); receiving valid voice data through a wireless microphone receiver from a speaker which speaks through a wireless microphone transmitter(202,203); extracting a feature from the received valid voice data(203); generating at least one speaker model by using the extracted feature(204); and recognizing the speaker by measuring similarity between the extracted feature and the generated speaker model(205~207).
