Espressif Systems ESP32-LyraTD-DSPG Audio Development Board

Espressif Systems ESP32-LyraTD-DSPG Audio Development Board is based on the ESP32 MCU and DBMD5P DSP. This board is an Acoustic Echo Cancelation (AEC) solution supporting voice recognition, near-field, and far-field voice wake-up. Audio files in the format of WAV, MP3, AAC, FLAC, OPUS, and OGG can be decoded and encoded without quality loss. It also supports connection to Amazon’s AVS (Alexa Voice Service), Google's Dialogflow, and Google's GVA (Google Voice Assistant). Custom voice-interactive products can also be built with this solution by using ESP-VA-SDK (Espressif’s voice assistant SDK) and ESP-ADF (Espressif Audio Development Framework).
