In fields such as smart homes, consumer electronics, and automotive electronics, voice recognition technology has been deeply integrated into various devices. By embedding voice chips, these devices can recognize and execute user voice commands—whether it’s starting, adjusting, or shutting down—all accomplished with just a word, greatly simplifying the operation process.

CI13XX Series: Leading the Way with High-Performance AI Voice Chips

In 2021, Chipintelli launched the 3rd generation high-performance AI voice chip series CI13XX. Based on the self-developed BNPU (Brain Neural Processing Unit) 3.0, this series features a system main frequency of up to 240 MHz and 640 KByte of SRAM, complemented by rich peripheral interfaces (including up to 3 UARTs, 1 IIC, 1 IIS, 6 PWMs, and 26 GPIOs, among others). It enables functions such as voice recognition, voiceprint recognition, offline natural speech, command word self-learning, voice detection, and deep learning noise reduction. With its powerful computing performance, accurate and fast voice recognition capability, and support for up to hundreds of thousands of vocabulary entries, it is widely used in products such as air conditioners, washing machines, range hoods, and clothes dryers. With an annual shipment volume of tens of millions of units, it ranks among the top in the voice chip market.

CI13LC Series: The Perfect Balance of High Performance and Low Cost

For small household appliances and consumer products that only require simple commands and have strict cost requirements, Chipintelli has also customized and launched the high-performance, low-cost 3.5-generation cost-effective AI voice chip series CI13LC, which is currently the best value-for-money choice on the market. This series offers a system main frequency of up to 210 MHz and 288 KByte of SRAM, adopting BNPU 3.5—meaning it has stronger and more flexible computing performance than the 3rd generation chips. It supports neural networks such as DNN, TDNN, RNN, CNN, and LSTM, as well as vector parallel computing, enabling functions like voice recognition and voice noise reduction, and supports up to 300 offline voice entries. While maintaining performance improvements, this series achieves a significant cost reduction through optimized design and trimming of some non-core resources, providing a cost-effective voice solution for cost-sensitive products. It can be applied in fans, lighting, tea brewers, heaters, toys, and other products.

The CI13LC series chip models include CI13081, CI13161, CI13162, CI13242, CI13322, etc. The main differences between these models lie in the packaging form, Flash memory, and peripheral control interfaces, allowing flexible adaptation to different customer needs.

From the mid-to-high-end to the mass market, Chipintelli has successfully built a complete product system of high, mid, and low-end voice chips through continuous technological innovation and product iteration. In the high-end field, the company continues to promote the 3rd generation CI13XX series chips, focusing on multifunctionality and a strong user experience. In the mid-to-low-end product market, it carefully crafts the cost-effective 3.5-generation CI13LC series chips, mainly targeting small household appliances and consumer markets. Facing the broader environment of consumption downgrading, Chipintelli remains dedicated to continuously improving end-user experiences and reducing costs through AI chips, committed to promoting the healthy development of the entire intelligent voice industry.
