摘要： In an echo processing method and device which can detect an accurate echo section without effects of a far end signal, an echo delay, and a reduction of an echo cancellation amount, a signal of a specified frequency band is generated in conformity with a near end signal, and the signal of the specified frequency band is added to the near end signal to form a transmitting signal. Receiving signals are separated into the signal of the specified frequency band and a signal of a band other than the specified frequency band. An echo section is detected based on the signal of the specified frequency band separated. An echo component in the signal of the band other than the specified frequency band is removed and a level of the echo component is detected based on the near end signal in the echo section. Each step may be performed with a digital signal, the transmitting signal may be converted into an analog signal to be inputted to a 2-wire/4-wire converter, the receiving signal may be outputted from the 2-wire/4-wire converter to be converted into the digital signal.
