VC-02 Kit Offline AI Voice Recognition Module

Hello! Everyone,
Welcome to Aviyan's Thoughts,
In this video I've described about How to upload firmware to VC-02 Kit Offline AI Voice Recognition Module from the very basic level. So, you will learn very easily. Please watch the full video step by step and I hope you will enjoy it.

About VC-02 Kit Offline Voice Recognition Module :
VC series module is a low-cost pure offline speech recognition module developed by Shenzhen Ai-Thinker Technology Co., Ltd. The module uses the voice chip US516P6 launched by Unisound. It features high reliability and versatility. Highly reliable wake-up recognition rates, more distant wake-up, more low-incorrect wokens, more low-erroneous wake-up rates, more low-than-off, faster response identification time, secreted pure line identification.

The VC Series module adopt a 32bit RISC architectural kernel and has joined the DSP instruction set required for signal processing and speech recognition, support floating point operations, and FFT accelerators. Supports up to 150 local instructions offline identification, support RTOS lightweight systems, as well as simple and friendly customary tools.

The VC Series module has a rich peripheral interface, including UART / I2C / PWM / SPI, and simple&friendly secondary development tools for customers to implement a single-mode group speech control application scenario scheme.

Features :
Support bilingual control, both Chinese and English
Single MIC Access
Support AEC echo elimination, steady-state noise reduction
Support to wake up from learning, no need to compile firmware
Comprehensive recognition rate can reach more than 98%
Identification time is less than 100ms
Extremely low error rate
Entry corpus up to 150
