Revolutionary Low Power, Small Footprint DBMD2S Enables Always-On and Sensor Hub Features as Well as Unparalleled Voice Quality and Call Intelligibility for Mobile and Wearable Devices

SAN JOSE, Calif. -- DSP Group(R), Inc. (Nasdaq:DSPG), a leading global provider of wireless chipset solutions for converged communications, unveiled today DBMD2S, an innovative and comprehensive voice and audio enhancement product for mobile devices that supports enhanced noise cancellation, voice activation and sensor hub functionality, enabling ultra-low power, always-on capabilities.

Introducing Always-On, Sensor Hub Capabilities

DBMD2S, DSP Group's latest voice enhancement processor enables device activation and operation via voice commands while maintaining extremely low power consumption.

Sensor hub functions include capturing data from multiple sensors such as microphones, biometrics, accelerometers, gyroscopes, and magnetometers, and also from environmental sensors such as light level, color, temperature, pressure, and humidity gauges. Moreover, DBMD2S features advanced sensor fusion algorithms, providing simultaneous analysis of data from multiple sensor sources with very low power consumption.

Improving User Voice Experience and Productivity

Incorporating DSP Group's enhanced second-generation HDClear(TM) noise cancellation technology, DBMD2S dramatically improves user voice experience, delivering unparalleled call quality and intelligibility. When integrated in smartphones, wearable devices and other mobile devices, DBMD2S leverages HDClear to achieve more effective isolation of voice from surrounding environmental sounds in any holding position - even in environments with high ambient noise levels.

DBMD2S also markedly enhances the performance of Automatic Speech Recognition (ASR) applications. Using HDClear's robust and powerful noise reduction algorithm, DBMD2S effectively filters ambient noise of any kind and delivers "cleaner" speech to ASR applications, resulting in best-in-class accuracy, enhanced ASR consistency, and improved productivity.

DBMD2S supports advanced audio and voice features including Audio Focus, Acoustic Echo Cancellation (AEC), Automatic Gain Control (AGC), Flexible Listening Enhancement (FLE), Flexi Speech (enabling users to change the speed of incoming voice), and more.

"There is a growing demand for complex processing of information about user activity and surroundings, utilizing a dedicated low-power, always-on processor. This enables consumers to enjoy an intelligent, considerate 'mobile companion' that can addresses their actual needs with eye-free, hands-free operation," said Ofer Elyakim, Chief Executive Officer of DSP Group. "DBMD2S ideally addresses this evolution with advanced features like voice activity detection and sensor hub functionality, in addition to a comprehensive suite of voice enhancement solutions - without compromising on power consumption," he continued.

Clear Technical Superiority

DBMD2S embeds a programmable 32-bit DSP, incorporates advanced connectivity options including four TDM/I2S ports, I2C 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.

As an open platform, DBMD2S allows mobile OEMs to offload voice and audio tasks from the device's application processor while running HDClear to enhance voice and video call intelligibility. OEMs can leverage DBMD2S's open and flexible architecture to differentiate their products by utilizing available DSP MIPS headroom and memory to run their own or third-party voice/audio enhancement software for pre and post-processing.

DSP Group will present its solutions for smartphones, wearable devices, and mobile devices at the Mobile World Congress in Barcelona, February 24-27 in DSP Group's meeting room, 2G20MR in Hall 2, and at CEVA's booth in Hall 6, stand 6A50.
