 ESP-SR is a speech recognition framework developed by Espressif for the field of intelligent speech. ESP-SR can provide high-performance and high-reliability speech recognition functions for developers by using ESP32-S3 AI extension instructions. Now, this framework has three modules:
 
-1. Espressif's acoustic algorithm ([Audio Front-End, AFE](https://github.com/espressif/esp-sr/tree/3ce34fe340af15e3bfb354c21c1ec2e6e31a37e8/docs/acoustic_algorithm)), which is specially designed to improve speech recognition performance in far-field or noisy environments to enable developers to obtain high-quality and stable audio data. It mainly includes AEC (Acoustic Echo Cancellation), BSS (Blind Source Separation), NS (Noise Suppression). ESP-SR encapsulates the above algorithms into simple APIs. Without understanding details of these algorithms, developers only need to arrange and combine the algorithms that need to be used for specific application scenarios, and input the voice data to be processed according to the API format requirements and can get the results.

WakeNet uses MFC (Mel-frequency Cepstrum) to obtain the features of the input audio clip, then classifies the characteristic signals by the neural network algorithm optimized for ESP32-S3. That can trigger the wake-up signal when analysed the command word, and the [effective recognition rate](https://github.com/espressif/esp-sr/tree/3ce34fe340af15e3bfb354c21c1ec2e6e31a37e8/docs/wake_word_engine/README.md#performance-test) is more than 80% in a noisy environment.
