AudioSmart Solutions from Conexant to Target Far-Field Voice Processing for TVs, PCs, Smart Phones and Tablets

Speech as User Interface and Drive for High Quality Voice Set Tone for Consumer Electronics

Conexant's AudioSmart products enable the emerging trend for enhanced user controls through voice input. They are designed for applications that combine embedded audio and voice, such as Smart TVs, smart phones and tablets.

2014 International CES

LAS VEGAS--()--With a broad range of voice interactive and audio capturing devices entering the consumer electronics market, it is clear that the freedom to communicate in many places with many devices is an idea that is quickly becoming mainstream. Safety concerns also play a role here, as hands-free communications are the law in many states. Using voice to enhance the user interface is a trend that is currently seen in everything from gaming consoles to cars and TVs, and this trend is poised for widespread adoption in other areas, including smart phones, tablets, wearable computing (i.e. smart watches, fitness devices and Smart Glasses) – and even a completely voice-controlled home.

Traditionally, phones have been our main means of communication and current voice processing solutions are optimized for phones being held within a few centimeters of the user’s mouth (near-field conditions). Today, people communicate through and control a broader range of connected devices, where the device will not likely be held close to the user’s mouth and in environments where the surrounding noise level may be high. In these situations, where traditional near-field voice processing solutions fail, Conexant’s AudioSmartTM far-field voice processing solution mitigates the effects of these challenging conditions and enables the clear voice communication and accurate speech control that users expect. For example, the ability to have an intelligible video chat with friends on a tablet from a noisy coffee shop, or control and communicate with a smart phone hands-free while driving despite surrounding wind and road noise. High quality far-field voice processing is not only increasingly important for current applications such as smart phones, tablets, PCs and TVs, it is a requirement for emerging applications where the traditional touch interface does not apply.

This week at the 2014 International CES, Conexant Systems Inc., an audio and imaging innovation leader, will be showcasing its AudioSmart solutions that make everything from Smart TVs to home appliances smarter – and able to respond to voice commands. Conexant, makers of the only far-field voice input processing chip solution in production for TVs, is the clear industry leader and is expanding the adoption of its technology in other applications. At CES, Conexant will be demonstrating its AudioSmart far-field voice processing solution in Smart TVs, Windows-based PCs/laptops/convertibles and Android-based smart phones. Conexant’s AudioSmart software enables a rich audio experience including accurate voice control, clear voice communication and immersive audio playback. The solution has been optimized to work with all popular VoIP clients and all major speech recognition engines. With Conexant’s far-field voice input processing, truly hands-free, eyes-free control can be realized.

In contrast with existing voice processing solutions that were created for the near-field phone application, Conexant’s technology was created with the most challenging far-field environment in mind, the Smart TV. Leading the way to a smarter, voice-enabled future, Conexant has successfully demonstrated the power of its far-field voice input processing solutions for Smart TVs. The recently announced CX2092x, incorporating Conexant’s third generation far-field voice processing technology, offers a highly accurate, robust way to control TVs by using voice, and has been adopted by LG for its 2014 lineup of Smart TVs. Conexant also brought the world’s first far-field class microphone ADC to market. Proprietary algorithms for far-field processing help to suppress certain surrounding noises in the environment, placing the focus on the dominant voice signal in the room and ensuring an extremely high speech recognition rate and clearer voice communications when a user is at a distance from the device (within four meters). With highly accurate far-field speech recognition performance, Conexant goes one step further by enabling natural language speech control, wherein users are not tied to a specific set of commands that the end device can understand. Its high-performance voice processing allows users to speak to their TVs in a normal fashion, using words and phrases of their choice – for a truly smart audio experience.

Conexant’s AudioSmart solutions offer the optimum mixed signal and DSP technology for high-fidelity voice and audio processing. “We recognize that voice is a natural extension of the user interface,” notes Saleel Awsare, Conexant vice president and general manager. "We are the first to offer a two microphone solution with flexible placement options, and our ability to deliver a high hit-rate and excellent voice clarity at a distance of up to four meters is an industry first as well.”

        Key features of Conexant’s AudioSmart far-field voice processing include:


Two microphone solution with flexible mic placement options for lower costs


High hit-rate speech recognition and voice clarity – even when the user is up to four meters from the device


Excellent voice quality, independent of the user’s angle relative to the device or the device orientation (i.e. portrait, landscape)

Conexant’s chip solution for Smart TVs and appliances is in production and available now. The company’s software only Windows solution for PCs is sampling. The Android software only solution for smart phones, tablets and wearables will be sampling soon. Please visit for more details.
