Abstract

This paper proposes an acoustic echo control solution for voice control devices. An important property of an acoustic echo canceller is its capability to handle double-talk and be able to operate in real time. When it is applied to intelligent voice control device with interactive conversations, it is important to suppress the speech from the device and enhance the speech of the user for speech recognition, where doubletalk situation is frequently occurred. The main idea is to use a robust adaptive algorithm to handle the double-talk. In order to achieve real-time adaptation, subband processing together with a hardware accelerator implemented in an FPGA fabric surrounding a PowerPC on a Xilinx XUP V2P platform.
