Conexant Systems has announced that its far-field voice input processor system-on-chip (SoC), the CX2092x, has been adopted by South Korean operator LG Uplus for two new smart home products – the tvG Woofer Set Top Box (STB) and the IoT Hub. Hardware and electronics for the new products were designed by LG Electronics. Conexant’s CX2092x enables users of these smart products to control them using their voice, from across the room and at any angle relative to the product’s microphones.

LG Uplus’s new tvG Woofer STB includes stereo surround sound via an integrated four-channel speaker and two woofers in a single sound plate form factor. The new IoT Hub from LG Uplus enables control of and communication with home security systems, thermostats, lights, heating/cooling systems, and more. Leveraging Conexant’s technology, which is designed to eliminate background noise in real-world environments, users can issue speech commands anytime, from anywhere in the room.

The CX2092x combines an integrated DSP CODEC processor with voice processing algorithms to create a distant-speaker voice processing service for consumer electronics. Key features of the CX2092x include fully-integrated Wake-on-Voice service with embedded third-party speech recognition engine; speech recognition hit rate and clear voice quality; compatibility with multiple speech recognition vendors; and dual 24 bit ADC and microphone preamp with independent microphone bias supply.
