Description du produit

The low-power offline voice recognition module is designed for battery-powered and portable products, as well as various products with stringent power consumption requirements. Leveraging next-generation voice recognition technology and algorithms, it deeply integrates offline recognition algorithms with chip architecture, providing customers with a comprehensive voice recognition solution. It can be widely and rapidly applied to various battery-powered small appliances, portables, jouets, and voice-controlled products like single-wire 86 boxes.

The module uses an MCU + voice recognition dedicated NPU core architecture, adopting ultra-low power process technology. It has a built-in high-precision voice detection module and a multi-level system startup mode, reducing standby power consumption to sub-milliwatt levels and operating power consumption to a few milliwatts. With built-in SRAM and FLASH, it requires only a few peripheral components to form a complete solution.
