Wake Word Detection

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example is used to test performance of wakenet.(the word word engine of Espressif). This example can load multiple models, but can only run two models at the same time

Configure

Select board and wake words

idf.py set-target esp32s3
idf.py menuconfig

# Select audio board
Audio Media HAL -> Audio hardware board -> ESP32-S3-Korvo-1

# Load one wakenet model
ESP Speech Recognition -> Select wake words -> Hi,Lexin (wn9_hilexin)

# Load multiple wakenet models
ESP Speech Recognition -> Select wake words -> Hi,Lexin (wn9_hilexin) -> Load Multiple Wake Words
ESP Speech Recognition -> Load Multiple Wake Words -> Hi,Lexin (wn9_hilexin)
                                                   -> Hi,ESP (wn9_hiesp)
