DSP Group Unveils Next-
Generation Ultra-Low-Power
Always-On Voice Processor
Optimized for Google Hotword and
Sensory TrulyHandsfree, DBMD4
Enables Best-in-Class Performance
for Mobile, Wearables and IoT
LOS ALTOS, Calif., Feb. 22, 2016
(GLOBE NEWSWIRE) — DSP
Group®, Inc. (NASDAQ:DSPG), a
leading global provider of wireless
chipset solutions for converged
communications, unveiled DBMD4
– its next-generation, ultra-low-
power, always-on voice and audio
processor. The DBMD4 platform
features a notably small footprint,
offers the lowest power consumption
and best-in-class enhancements for
always-on voice operation, elevating
performance and functionality of
battery-operated devices.
Ultra Low Power Always-On Voice
Activation for Any Device
Adoption
of
voice-enabled
applications such as smart
assistants, voice commands and
voice search is proliferating in
mobile, smartwatches and IoT
devices. DBMD4 allows battery-
operated devices to actively listen
and sense voice activity and
commands while in ultra-low power
mode – alleviating battery strain,
improving device usability and
extending battery life.
DBMD4’s
power-optimized
implementation for always-on voice
is based on Sensory TrulyHandsfree
and Google Hotword. In addition,
DBMD4 supports six seconds of
voice buffer that enables seamless
operation. DBMD4 is a completely
autonomous,
audio-centric
processing solution enabling power-
hungry application processors in
mobile and wearable devices to
actually sleep during voice sensing.
“The consumer and enterprise
use of mobile smart assistants
is on the rise. This creates a real
need for a low-power solution
that enables users to enjoy these
functionalities via a simple voice-
enabled interface,” said Harry
Wang, Research Director at Parks
Associates. “Integrating with both
mobile and wearable devices, DSP
Group’s solution will further increase
the usage of such applications
– creating value for application
developers, service providers, and
end users,” he concluded.
“We are excited to be working
closely with DSP Group to enable
the first DSP with Sensory’s low
power always listening hardware
block,” said Todd Mozer, CEO of
Sensory. “DBMB4 features built-
in handshaking with Sensory’s
TrulyHandsfree, which gives it
a winning combination of power
consumption and accuracy in trigger
word listening environments,” he
continued.
High-Performance
Voice
Enhancement Suite
DBMD4 incorporates a suite of
voice enhancement algorithms
including
noise
suppression
that significantly improve user
experience and accuracy of speech-
driven applications, particularly in
high noise environments.
When integrated in smartphones,
wearables and IoT devices, DBMD4
leverages these algorithms to
achieve more effective isolation
of
voice
from
surrounding
environmental sounds. This enables
effective voice operation in almost
any environment. DBMD4 also
supports advanced audio and voice
features including Acoustic Echo
Cancellation (AEC), Automatic Gain
Control (AGC), Beam Forming and
more.
Smaller Form-Factor, Technically
Superior
DBMD4 offers a markedly small 1.8
x 2.1mm form factor, making it ideal
for a variety of mobile, wearable
and IoT devices.
Embedding a programmable low-
power DSP, DBMD4 supports
digital and analog microphones and
incorporates various Application
Processor Interfaces such SPI, I2C,
UART and SLIMbus. The platform is
also equipped with a comprehensive
software framework and a complete
suite of Android drivers for Lollipop
5.x that enables rapid development
and fast time-to-market.
“We foresee a bigger role for voice
and audio in consumer devices for
smart processing and sensing –
including mobile, wearables and
IoT,” said Ofer Elyakim, CEO of DSP
Group. “With advanced features like
low-power always on and best in
class voice enhancement solutions,
we believe that DBMD4 is uniquely
positioned to play an instrumental
role in this evolution,” he added.
DSP Group will present its solutions
for smartphones, wearable devices,
and IoT at the Mobile World
Congress in Barcelona, February
