One of the key themes throughout my tour of CES 2015 exhibits was the wireless of infrared control of the Smart Home. Using your Smart Phone or Tablet, exhibitors showed how you could easily control many functions in your home.
I am of the belief that inside the home a very natural way to control your Smart Home is your voice. Speaking is a comfortable way to communicate and we do not often do that anymore with e-mail and texting being the means of choice for communication with others. Well, as far as I am concerned, voice is the means I prefer in the Smart Home because it is the most natural means of communications.
There are certainly some challenges with voice such as background noise, loudness and clarity of our words, even slight accents in speech. Conexant demonstrated to me how they have refined the art of voice-control with some innovative, engineering solutions. I was impressed.
To accomplish background noise elimination in a typical home environment, Conexant uses their unique far-field voice processing technology. Far-field voice processing for smart home applications is not based on traditional beamforming. Traditional beamforming requires users and noises to be at pre-defined angles relative to the product’s microphones, which are not practical for most smart home applications. On the other hand, the Conexant solution takes real-world environments into consideration and is based on Blind Source Separation (BSS). BSS enables excellent speech recognition performance from up to five meters away, at any angle, and with only two microphones – even when noise is in the same direction as the voice.
This Linux-based solution is the newest addition to a portfolio that already includes Conexant’s software solution for Windows and Android operating systems, Conexant’s DSP CODEC solution for embedded applications, and its high dynamic range microphone ADCs for optimal far-field pick-up.
This unique combination of hardware and software is a winning design that has enabled true and accurate voice control in the Smart Home.
