Product Descriptions

VC-02 is a low-cost pure offline speech recognition module that uses the US516P6 speech chip launched by Yunzhisheng.

The US516P6 chip adopts a 32-bit RSIC architecture core and incorporates a DSP instruction set specifically designed for signal processing and speech recognition, an FPU operation unit that supports floating-point operations, and an FFT accelerator. Supports 1 analog Mic input, SNR≥94db; Support 4-channel digital Mic input; Supports dual channel DAC output; Supports 12S input/output.

VC-02 module size: 18 * 17 * 3.2 ± (0.2) mm, packaged as SMD-20, supports offline recognition of 150 local instructions, supports lightweight RTOS systems, supports multiple interfaces such as UART/SPI/I2C/ADC/PWM/GPIO, and simple and user-friendly customization tools. Built in 242KB high-speed SRAM and 2MB FLASH; Supports power input in the range of 3.6V-5V, with built-in 5V to 3.3V and 3.3V to 1.2V LD0 for chip power supply.

We continuously optimize and innovate algorithms in speech recognition technology, deeply integrating offline recognition algorithms with chip architecture to provide customers with ultra-low cost offline speech recognition solutions. These solutions can be widely and quickly applied to smart homes, various smart small appliances, 86 boxes, toys, lighting fixtures, and other products that require voice control.
