Conexant, Unisound Partner on Voice Control for Smart Devices

Conexant Systems is partnering with voice recognition and processing technology provider Unisound. Using the Conexant CX2092x high-performance far-field voice input processor system-on-chip (SoC), the resulting solution is designed for the Chinese smart appliance market.

The first product to contain the technology will be a smart air conditioner. Adding natural voice control, Conexant is improving the way that consumers interact with these appliances, creating a user-centric, personalized experience that requires no remote control.

"By including Conexant's technology, we are able to bring best-in-class voice control features to the home devices our customers use most," noted Heng Kang, Unisound's chief operations officer, in a statement. "Tech-savvy Chinese consumers are embracing smart home technology to a greater extent than their global counterparts, and it's crucial that we offer them the most innovative, forward-thinking products that we can. Conexant enables us to do this."

Leveraging Conexant's technology, which eliminates background noise in real-world environments, users can issue speech commands anytime, from anywhere in the room, without worrying about interference, including the noise coming from the air conditioning unit itself.

The CX2092x combines an integrated digital signal processor CODEC processor with voice processing algorithms to create a true distant-speaker voice processing solution for consumer electronics.

Key features of the CX2092x include the following:

  • Fully integrated wake-on-voice solution with embedded third-party speech recognition engine;
  • Compatibility with multiple leading speech recognition vendors; and
  • Dual 24-bit ADC and microphone preamp with independent microphone bias supply.

"China is a key player in the smart home revolution. Our partnership with Unisound is designed to create a connected world of intelligent systems that listen, understand, and engage on a human level," said Saleel Awsare, Conexant senior vice president and general manager, in a sttement. "We are also working closely together on next-generation applications that will include our four-microphone voice input processing solution, for an immersive, 360-degree user experience."
