Las Vegas, Nev. − At the 2014 Consumer Electronics Show (CES), Conexant Systems Inc. unveiled its CX2092x high-performance far-field voice input processor system-on-chip (SoC) designed specifically for smart TVs. The chip uses third generation voice processing technology to deliver "superior voice control with excellent speech recognition hit rates and voice communications with increased clarity in far-field conditions – up to four meters away from the TV," according to Conexant.
The new chip is part of Conexant’s AudioSmart solutions and offers a highly accurate way to control TVs with voice by making advanced control and search more efficient than traditional pushbutton remote controls. The CX2092x provides an "always-listening" mode in an ultra-low-power state, thanks to a low-power and small footprint speech recognition engine running with the chip, enabling the TVs to meet worldwide energy standards for standby power, said Conexant.
Key features include:
- Fully-integrated Wake-on-Voice solution with embedded third-party speech recognition engine
- Excellent speech recognition hit rate and clear voice quality
- Compatibility with multiple leading speech recognition vendors
- Reference design with pre-tuned “hidden” microphone module for industrial design esthetics and performance
- Dual 24-bit ADC and microphone preamp with independent microphone bias supply
LG is the first to adopt the CX2092x, and will implement it in its 2014 TV lineup.
Availability: The CX2092x is available in a 60-QFN package. EVKs are currently available to qualified customers and partners for $500.
Pricing: Starts at $5.18 each in quantities of 100,000.
