In smart homes, consumer electronics, automotive electronics, and other fields, speech recognition technology has been deeply integrated into various devices. By embedding speech chips, these devices can recognize and execute user speech commands. Whether starting, adjusting, or shutting down, tasks can be completed with just a spoken word, greatly simplifying operational processes.
CI13XX Series: Leading the Way in High-Performance AI speech Chips
In 2021, Chipintelli launched the 3rd-generation high-performance AI speech chip series, CI13XX. Based on its self-developed BNPU (Brain Neural Processing Unit) 3.0, this series features a system main frequency of up to 240MHz, 640KB SRAM, and rich peripheral interfaces (including up to 3 UARTs, 1 I2C, 1 IIS, 6 PWMs, and 26 GPIOs). It supports functions such as speech recognition, speechprint recognition, offline natural speech processing, command self-learning, speech detection, and deep learning noise reduction. With its powerful computing performance, fast and accurate speech recognition capabilities, and the ability to accommodate hundreds of thousands of command entries, the CI13XX series is widely used in products like air conditioners, washing machines, range hoods, and smart clothes dryers, achieving annual shipments of tens of millions of units and leading the speech chip market.
