Espressif Systems ESP32-LyraTD-SYNA Audio Development Board

Espressif Systems ESP32-LyraTD-SYNA Audio Development Board is a hardware platform based on the ESP32 Microprocessor and Synaptics Digital Signal Processor (DSP). The board is an Acoustic Echo Cancellation (AEC) solution that supports voice recognition and wake-up. The device can decode and encode WAV, MP3, AAC, FLAC, OPUS, and OGG formats without quality loss. The board also supports connections to Amazon's AVS (Alexa Voice Service), Google's Dialogflow, and Google's GVA (Google Voice Assistant). ESP32-LyraTD-SYNA is also based on ESP32-WROVER-B, a BLUETOOTH®/Wi-Fi® combo module, and a DSP with a two-microphone array for noise reduction and echo cancellation.
