Overview

This is the low-power far-field voice local command (FFD) example design with Wanson speech recognition and local dictionary.

While inactive, low-power mode uses a fraction of energy otherwise required by normal operations while awaiting and processing speech.

When a wake-up phrase is followed by an command phrase, the application will output an audio response and a discrete message over I²C and UART.

This software is an evaluation version only. It includes a mechanism that limits the maximum number of recognitions to 50. You can reset the counter to 0 by restarting or rebooting the application. The application can be rebooted by power cycling or pressing the SW2 button.

Note

Due to the hardware design, SW2 is only functional when in full-power operation.
