Nortek Selects DSP Group’s SmartVoice With HDClear™ For Numera® Libris 2® Mobile Personal Emergency Response System (mPERS)

Enables crystal clear two-way voice interaction in emergency situations to complement mPERS’ suite of advanced features, such as voice-call activation upon fall detection.

LAS VEGAS, Jan. 09, 2020 (GLOBE NEWSWIRE) -- DSP Group® (NASDAQ: DSPG), a global leader in wireless and voice processing solutions, announced that Nortek Security & Control has selected DSP Group’s SmartVoice system-on-chip (SoC) with HDClear™ advanced low-power voice processing algorithms to power its Numera® Libris 2® mobile personal emergency response system (mPERS). DSP Group’s SmartVoice technology allows the Libris 2 to maintain a crystal-clear two-way voice call with emergency response services upon activation through fall detection or deliberately by the user.

In such situations, every second matters. After a fall, the user may be in a weakened state, immobilized, faint of voice, and in and out of consciousness. The Libris 2 itself may have fallen off of or be covered by the user. In all these scenarios, the combination of the SmartVoice SoC and HDClear form the critical elements for crystal clear two-way voice interaction and contribute greatly to condition monitoring and rapid user recovery.

“An aging demographic on a global scale, a demand for greater independence and mobility, and rapidly changing healthcare regulations, have combined with advances in semiconductor and voice processing technology to allow us to truly make a difference in people’s lives,” said Ofer Elyakim, CEO of DSP Group. “We are excited that Nortek chose our SmartVoice SoC and HDClear algorithm to contribute to user quality of life and enable potentially life-saving features such as two-way voice interactions.”

The SmartVoice SoC is an audio/voice SoC optimized for voice-processing algorithms, while HDClear is a specific set of voice processing algorithms that supports two-way voice-call, along with other voice/audio related features, such as continuous wake-word listening and voice activation. DSPG’s two-way voice technology also complements the many ground-breaking advances on the Numera Libris 2, including improved GPS location accuracy and 4G/LTE support, advanced fall detection based on sensors and cloud-based fall-detection analysis.

“The Libris 2 embodies the latest in advanced mPERS features and capabilities that allow us to bring security, safety, and peace of mind to both users and their caretakers alike,” said Michael Pirie, Nortek Security & Control Vice President of Health & Wellness. “One of the many decisions we have to make in any portable device is how to balance power consumption, features, and performance. Working with DSP Group has helped us greatly to optimize battery life while adding the features and performance our customers demand.”

The Libris 2 mPERS pendant will be showcased at CES 2020 (Jan 7 - 10) in DSP Group’s Private meeting room, along with a select array of the many products powered by DSP Group’s technologies. To secure a demo session contact
