reSpeaker Lite - USB 2-Mic Array with Onboard AI Audio Processing Algorithms (SE-107990273)

reSpeaker Lite – USB sústava s 2 mikrofónmi s integrovanými algoritmami spracovania zvuku pomocou umelej inteligencie, kompatibilná s Seeed Studio XIAO ESP32S3 (Sense), Raspberry Pi, Adafruit QT Py

Táto vývojová doska, poháňaná čipsetom XMOS XU316 AI Sound and Audio, vyniká v spracovaní zvuku vďaka integrovanému dvojitému mikrofónovému poľu, ktoré je ideálne na rozpoznávanie reči a hlasové ovládanie. Čip XU316, vybavený pokročilými integrovanými algoritmami NLU, zabezpečuje potlačenie rušenia, potlačenie ozveny a potlačenie šumu. Podporuje pripojenia I2S a USB a je kompatibilná s Seeed Studio XIAO ESP32S3 (Sense), Adafruit QT Py, Raspberry Pi a PC.

Dual Microphone Array for Far-Field Voice Capture: The 2 high performance digital microphones capture and extract far-field speech and voice (up to 3 meters) even in noisy environments as it cancels point noise using two microphone input.
Onboard Audio front-end Algorithms:: Powered by XMOS XU-316 AI sound and audio chip, the kit includes Natural Language Understanding algorithms for Interference Cancellation (IC) , Acoustic Echo Cancellation, Noise Suppression, Voice-to-Noise Ratio (VNR), and Automatic Gain Control (AGC), enabling high quality voice capture.
Embracing Open Source: This board is compatible with popular hardware platforms (XIAO ESP32S3 (Sense), Adafruit QT Py) via I2S, and compatible with Raspberry Pi, PC via USB (Audio Class 2.0 (UAC2)).
Onboard RGB LED: The board features a programmable WS2812 RGB LED, supporting custom effects and offering a visual interface for your applications.
External Power Supply Support: this board supports external 5V power supply, which can be flexibly applied in different scenarios.
DFU for Custom Development: the board supports custom firmware update via DFU-Util.
