SK Telecom, Korea's largest mobile carrier, is implementing Conexant Systems' AudioSmart far-field voice solutions to help the new NUGU smart speaker hear users' requests accurately from a considerable distance away from the device.

Conexant AudioSmart technology enables voice control in smart home applications, robots, IoT devices, and more.

"When developing the NUGU personal digital assistant, our engineers focused heavily on ensuring it would provide an optimal voice-enabled user experience," said Myung Soon Park, senior vice president of the Future Technology R&D Center at SK Telecom, in a statement. "When choosing a technology partner to help us achieve the level of speech recognition accuracy we wanted, Conexant was an obvious choice. Their technology allows our NUGU personal digital assistant to overcome distance and noise related challenges and offer ideal near- and far-field speech recognition performance, as well as enables users to interrupt and interact with the device when it's playing media."

Enabling speech recognition and voice control from a distance in smart platforms requires overcoming substantial challenges related to echo cancellation, background noise, microphone speaker position, and more. Conexant solutions can separate voice commands from background noise so that the speech recognition engine hears the user's command.

"As the voice-enabled revolution continues to shift the way people interact with devices of all types, reliance on speech enhancement technologies that help devices hear user commands more accurately will continue to grow," said Saleel Awsare, president of Conexant, in a statement. "Conexant has been a leading provider of voice processing solutions that improve speech recognition accuracy and enable advanced voice capabilities for years. We are pleased to be working with SKT to bolster the speech recognition performance of their NUGU smart speaker."
