# Overview

This is the XCORE-VOICE far-field voice assistant example design.

This application can be used out of the box as a voice processor solution, or expanded to run local wakeword engines.

This application features a full duplex acoustic echo cancellation stage, which can be provided reference audio via I2S or USB audio. An audio output ASR stream is also available via I2S or USB audio.

By default, there are two audio integration options. The INT (Integrated) configuration uses I2S for reference and output audio streams. The UA (USB Accessory) configuration uses USB UAC 2.0 for reference and output audio streams.
