Quantimetrica Ltd., is a London, UK based company
with a significant telecommunications and
quantitative skill-set, formed in July 2013. They
specialise in audio related internet of things (IoT)
hardware and software.
In a nutshell: what problem
is solved
Quantimetrica have developed
a p o w e r e f f i c i e n t v o i c e
activated proprietary system
that can trigger any external
piece of hardware via a
custom voice prompt.
In IoT, many more appliances
without high processing power,
will need to work via a voice
trigger efficiently and with low
power consumption.
The system controls devices or
applications:
• by voice remotely
• w i t h o u t a n i n t e r n e t
connection
• using ultra low power
• b y d e t e c t i n g u s e r
presence to shut down
redundant devices and
conserving energy.
QM1: An ultra low power
voice switch
The other end of the 'Siri-
Google Now-Cortana'
spectrum
Quantimetrica focus at the other
end of the spectrum from Apple’s
‘Siri’, Google’s ‘Google Now’ or
Microsoft's Cortana where the
need for a short voice trigger
which is low power, robust and
easy to port (and sufficiently
small in order to be affordable or
even disposable), is distinct from
large application, intensive high
p o w e r, v e r y h i g h e n d
c o m p u t a t i o n a l l y i n t e n s i v e
processors that have been
devised by names such as
Malaspina, Sensory, Rubidium,
Nuance, Qualcomm etc.
Quantimetrica have developed in-
house a unique algorithm that is
robustly responding to short voice
triggers (and hence implemented
in low memory devices at low
hardware cost) and is coded in
such a way that it can be ported
with relative ease to many
different platforms. The firm has
filed for a provisional patent with
the United States' Patent and
Trademark Office (henceforth
USPTO) for the algorithm and its
power saving features.
The algorithm's uniqueness has
b e e n d e m o n s t r a t e d i n
conferences such as Electronica
2014 in Munich and by Samsung
in collaboration with techUK in
London,where Quantimetrica's
voice trigger prototype performed
in a controlled and robust fashion.
Product description and
Go-to-Market
QM1 may take two forms:
• as a low power "voice
activated switch" - custom
software for an off-the-shelf
chip, but also
• a miniature module (17.4
x 13.84mm) with its own
microphone.
• 2 x 1 6 p i n h e a d e r
c o n n e c t o r s f o r e a s y
integration
First assembled units for QM1
have been manufactured and
the source code has been
optimised for low memory
footprint hardware so that
low cost microcontroller
variants can be utilised.
The PCB can support 3
v e r s i o n s o f t h e
microcontroller as follows:
• 4K or 16K RAM low
power M0+ core
• 1 6 K R A M h i g h
performance M4 core
with flash program memory
ranging from 32-128K.

designs or interfaces (e.g. Arduino,
Raspberry Pi etc)
• It can be reprogrammed on- site for new
trigger words (through standard
SWD interface
• It can be integrated with existing designs
due to small size and interfaces available
• Multiple QM1s can aggregate information
to a single access point to control via the
internet.
• Updated PCB with daughtercard connector
can integrate a number of peripherals (eg.
bluetooth, relay switches, LEDs etc.)

Competition
On one hand companies such as Malaspina, Sensory,
Rubidium, Nuance, Qualcomm operate with much
higher end/power requirements. At the other end,
the focus is in utilising an internet connection or
with clearly “always on” or with still higher power
consumption or implemented in more expensive
chipsets (e.g. DSP processors or FPGAs), much
restricting the application space.
The solution in the context of applications and
markets
Voice controlling electrical appliances, theoretically
gives one access to the 5.5 billion people who own
at least one such mains connected appliance (World
Bank 2012 data,78% of a 7bn total population).
Out of 7bn population, 1.32bn reside in the
developed world and with access to at least one
and, on average, 4 mains access points.
The US alone with 308mn population has 118mn
households for which this product could provide
tangible benefits in the manner described here. In
terms of the Global microcontroller market in 2008
this was a $13.75bn market. More specifically (Gran
View Research, June 2014)
• 17.4bn units in 2013, expected to reach 39.1bn
units by 2020, growing at a CAGR of 12.3% from
2014 to 2020.
• 32-bit microcontrollers (the category used by
Quantimetrica) accounted for over 34% of the
market in 2013; the segment is further expected
to dominate global market revenue over the next
six years. It is also expected to be the fastest
growing product segment, at an estimated CAGR
of 13.0% in terms of volume from 2014 to 2020.

Average power consumption becomes
99.7% of (1) + 0.3% of (2) = 0.389mW or
0.22mA
NOTE: this can be lower at fewer (than
50) 5 second activations per day
NOTE (at 1.8V supply):
(1): Listening for sounds at 0.35mW
(2): Processing at 13.3mW (but only for
5 minutes per day in total)

3. Products, opportunities and deployment for “voice switch”
In partnership with semiconductor companies, Quantimetrica can fit QM1 into every
day ‘less smart’ applications at home, the office, the factory or as explained earlier in
a variety of mobile devices as well. As such QM1, a form of a voice ‘switch’, may turn
applications off or on through certain voice inputs. Multiple such voice operated
devices can co-exist responding to different trigger words each.
Since 1.32bn people in the developed world have access to at least one application
via access to the electricity grid powering such application, there is ample opportunity
for providing a real benefit with this system.
Therefore with access to microphones and the
CPU, it is possible for appliances to trigger
many more of their functions remotely through
voice. The client segments for QM1 are
smartphone users, alarms, home and industrial
machinery, office equipment, cars, portable
devices, ships, trains, airplanes. Broad areas of
application in:
• Laboratory Issue voice commands when
user's eyes cannot be taken away from a
specific target (e.g. while operating a
microscope, telescope etc)
• Mobility Practical interface for such users finding
it difficult or impossible to use devices that are
by design small enough for portability (such as
those having small buttons and screens for their
use, e.g. glucose meters, sphygmomanometers,
insulin pumps etc)
• Wearables Display-less tiny mp3 players can be
considered, as well as fitness trackers and other, where the voice trigger cost
can outoutweigh the LCD display cost.
The firm’s voice trigger technology
incorporated as firmware upgrade
into existing appliances’ CPU could
f e a t u r e a n y w h e r e w h e r e
m i c r o p h o n e s a r e p r e s e n t
(cameras,toys etc.)
Quantimetrica plan to create such solutions that will be small and cost effective to
run. The algorithm has been developed as a low cost, low complexity solution that
reacts to a few simple words with the embedded system market as the target, so
that it could be manufactured at high volumes using low cost components. The
hardware is currently switching a LED on with one trigger word and off with another
one, but the LED signal can be routed to a relay to switch any mains operated
appliance or machinery.
It was made in such a
way as to be speaker
independent, requiring
no training.
