ESP32-S3-based intelligent voice solution verification board

Overview

Function Overview:
Voice Command Recognition: Recognizes voice wake-up words and command words, and runs predefined function calls.
Speech Synthesis: Voice broadcast of Chinese strings. Voiceprint
Recognition: Identifies the speaker's identity.
Voice Source Direction Recognition: Identifies the direction of the speaker's voice source (lower accuracy).

The main configuration of the verification board is as follows:
WIFI MCU: ESP32-S3, external 16M Flash for storing data and model files required for voice SR and TTS.
Voice ADC/DAC: ES8388.
Voice Amplifier: NS4150B.
MIC Array: Dual analog silicon microphones, spaced 4.0cm apart.
