OREANDA-NEWS. NEC Corporation has developed highly efficient noise suppression technologies that help ensure clear voice communications with smart devices by suppressing "tapping" sounds from touch-screen operations. These technologies preserve clear voice communications on smart devices, such as smartphones and tablets, while allowing users to comfortably take advantage of touch-screen functions.

In recent years, as smart devices rapidly spread throughout the world, there are a growing number of people using touch-screens during their conversations. These touch screens are used for a wide range of purposes, including map searches and document sharing. However, these operations cause unwanted noise from tapping with fingers and touch-pens that may interfere with the clarity of voice communications.  Even if these noises go unnoticed by a person speaking, the internal microphones of smart devices often detect these sounds and interfere with the quality of voice transmissions.

"NEC's newly developed technologies enable users to comfortably operate their touch-screens while free from concern about harming voice communications," said Yasunori Mochizuki, vice president, Information and Media Processing Laboratories, NEC. "When deployed with NEC's LT tablets, these technologies not only suppress tapping noise, they accomplish it without causing troublesome processing delays, which is important for users on-the-go."
