4. Need & Opportunity
Main problem:
Noise (including other speaker’s voice)
limits usage only to quiet environments
Opportunity: enable widespread
use of voice in significant markets
•Personal & Commercial communications
(Notebooks, Automotive, conferencing,
cellphones, etc.)
•Speech Operation
(Automotive, Notebooks, Gaming,
dictation, etc.)
Automotive Cellphones Calls
Home EntertainmentCall Centers
Conferencing

5. VocalZoom’s innovation
Combination of two independent sensors,
optical and acoustic, provides an unparalleled
improvement in Speech Enhancement
Noisy Audio Signal is received
by Acoustic Microphone
Digital filters are applied
to the Noisy Audio Signal
based on the Optical Signal
Optical sensor, immune to acoustic noise,
measures vibrations from throat/face of speaker
and converts data into Audio Signal
The result:
Noise Free audio signal

9. Competitive Testing
Noise scenario: Car driving at 100 KMH, Passenger talking, Driver issuing commands
Feb-139 VocalZoom Presentation

10. Automotive OEM - Testing Summary
• In-car testing on female and male subjects,
driving at 100 KMH (60 MPH)
• Car tests noise scenarios:
open/closed windows;
with/without background speaker
• Without VZ:
Recognition rate dropped to 0-40%
• With VZ:
VR engine maintained 60%-95% recognition rate

13. Integration options
• Simple analog microphone replacement
(with power)
• Simple digital microphone
(I2S interface)
• Feature-rich digital microphone,
providing parameters such as Pitch,
VAD and Speaker location,
in addition to Audio
Feb-1313 VocalZoom Presentation

14. Competition
• Several “noise cancelation” technologies exist (Directional Mics, Mic Arrays, and Bone
Conduction mics), but they all have major disadvantages:
• Mainly address stationary noise (wind, machinery, etc.)
• Can’t eliminate other voices (except bone conduction)
• Bone Conduction requires physical contact, and therefore can’t be integrated into end-user devices
• VocalZoom’s Competitive Advantage
• The only remote sensing technology able to isolate a target voice from any other noise
• Test results indicate a profound affect on Voice Recognition accuracy

16. Notebook/Tablet
Use case, Value add and Competition:
• Speech recognition for dictation and search
• Enabler for a huge market increase in VR usage,
for already large markets (Google Search, Siri, etc.)
• No direct competition
• Personal Audio and Video communications
• Enabler for conducting personal A/V communications
anywhere
• Main competition from mic-array, which has inferior
performance
Feb-1316 VocalZoom Presentation

17. Notebook NUI Comparable
• The market for touch screens, the latest
NUI addition, has grown significantly since
introduced
• At launch, a Touch Screen for iphone 4S
cost apple $14 in 2011 (isuppli teardown)
• People are willing to pay for a better UI
• Much more information can be expressed
by Voice, giving it the potential to be the
ultimate NUI
Feb-1317 VocalZoom Presentation

18. Home Entertainment
Use case, Value add and Competition:
• Speech recognition for voice operation, as well as superior quality for conferencing
• Enabler for robust handsfree operation in an inherently noisy environment
• No direct competition (under noisy conditions)
• Market validation:
• Companies such as Samsung have announced a voice-operated TV…
• But performance is less than adequate
• CNET review:
“when speaking to the TV's mic from the couch
I often had to repeat commands, and any extra
noise in the room was liable to interfere. ”
Feb-1318 VocalZoom Presentation

19. Personal & Commercial headsets
Use case, Value add and Competition:
• Usage as pickup sensor, positioned at close
proximity to the earpiece (very small boom)
• Superior voice quality and Speech Recognition
compared to acoustic mic
• Similar performance to Bone Conduction
(e.g. Jawbone), but with no physical contact
Feb-1319 VocalZoom Presentation
