DSP Group Unveils HDClear for Mobile

Feb 25, 2013

HDClearProvides Dramatic Improvement Over Existing Solutions in Both Noise Cancellation & Automatic Speech Recognition

DSP Group Introduces DMBD2 - The World's Most Powerful Voice Enhancement I

SAN JOSE, Calif., Feb. 25, 2013 (GLOBE NEWSWIRE) -- DSP Group®, Inc. (Nasdaq:DSPG), a leading global provider of wireless chipset solutions for converged communications, today unveiled its revolutionary HDClear solution, a comprehensive voice enhancement product for mobile devices. Incorporating proprietary, groundbreaking noise cancellation algorithms, HDClear dramatically improves user experience and delivers unparalleled voice quality and call intelligibility.

"DSP Group brings more than 25 years of market leadership in voice processing to the mobile market. Today, we are taking our voice offering one step further with HDClear, a disruptive voice processing technology that addresses a pressing challenge in mobile voice experience," said Ofer Elyakim, Chief Executive Officer of DSP Group. "Our roadmap is focused on reaching optimal voice enhancement performance, while creating an open architecture that provides our customers with the flexibility to differentiate their products," he continued.

When incorporated into smartphones and other mobile devices, this robust solution effectively isolates voice from surrounding environmental sound leading to a noise-free conversation experience and dramatically improved accuracy for Automatic Speech Recognition (ASR) applications enabling them to work the way they were designed to.

HDClear is now available on DSP Group's DBMD2, a new high-performance, low-power, small-footprint SoC for mobile devices, tablets, notebook PCs and SmartTVs.

DSP Group will present HDClear and DBMD2 at the Mobile World Congress in Barcelona, February 25-28, at DSP Group's meeting room 94 in Hall 2, and at CEVA's booth in Hall 7, stand 7i70.

HDClear - Making ASR Applications Reliable in Any Environment

HDClear addresses the growing demand for intuitive and easy-to-use speech-enabled applications. Currently, ambient noise poses a significant performance and accuracy hurdle for speech recognition engines. Since user experience depends on accuracy, powerful noise reduction technology is a key ingredient in making voice control a reliable and trusted interface in any environment.

Leveraging DSP Group's robust and powerful noise reduction algorithms, HDClear effectively filters ambient noise of any kind and delivers "cleaner" speech to ASR applications, resulting in best-in-class accuracy rates, enhanced ASR consistency, and improved productivity. HDClear clearly outperforms other available solutions, delivering consistent yet outstanding Word Error Rate (WER) under 20% in any ambient noise environment, contributing 50% or more in accuracy when compared to that of leading smartphones.

HDClear - Revolutionary Voice Enhancement Technology

HDClear improves voice call quality and intelligibility by eliminating ambient noise on both transmit and receive sides. Even in noisy environments, HDClear performs remarkably. In cases of a signal-to-noise ratio of 10dB, HDClear™ achieves approximately 10-15 dB SNR improvement (SNRI) when compared to that of leading smartphones.

HDClear also enables improved user experience in hands-free speakerphone mode and various other holding positions by isolating voice from the environmental noise more effectively. Incorporating DSP Group's celebrated Acoustic Echo Cancellation (AEC) technology, Automatic Gain Control (AGC), Flexible Listening Enhancement (FLE), Flexi Speech and more, HDClear is a powerful voice enhancement solution for mobile devices.

Introducing DBMD2 - The Industry's Most Powerful Voice Enhancement IC

DBMD2, the most efficient voice enhancement processor in the market, measures just 3.0 x 3.0 x 0.65mm. Offered with a 36-pin BGA and 0.4mm ball pitch, DBMD2 embeds a programmable 32-bit DSP, incorporates advanced connectivity options including four TDM/I2S ports and SLIMbus, and is equipped with a comprehensive software framework that enables rapid development and fast time-to-market - overcoming the challenges of portable design, real estate and power consumption.

An open platform, DBMD2 enables mobile OEMs to offload voice and audio tasks from mobile device CPUs, in addition to running HDClear to enhancing ASR accuracy. OEMs can leverage DBMD2's open and flexible architecture to differentiate their products by utilizing the free DSP MIPS headroom and memory to run their own or third party voice/audio enhancement software for pre- and post-processing.

"DBMD2 takes us to the next level of voice processing, providing our customers with a high level of performance, integration, and efficiency – along with the capability to more easily differentiate their products," said David Dahan, Chief Operations Officer of DSP Group. He continued, "DBMD2 sets a new baseline for audio DSP efficiency, enabling complete offloading of audio tasks from mobile device CPUs".

DSP Group's DBMD2 is currently sampling to customers globally. For more information on HDClear and more detailed specifications of DBMD2, please visit
