A Powerful Biometric Solution:

VOCAL PASSPHRASE
Vocal Passphrase is a groundbreaking biometric technology that defines the
modern concept of identity verification. Conventional security systems are
based on PINs, passwords and challenge questions which are not only
inefficient for growing incidence of fraud and identity theft but also cause
waste of time and customer dissatisfaction.
Vocal Passphrase provides secure access to systems through voiceprints of individual users.
The individual voice is enrolled to the system once and subsequent calls are authenticated
through this voiceprint. The solution can be applied in a variety of flexible ways according
to the needs of the customer such as a single layer or an additional layer of security to the
standard security procedures.
SESTEK Vocal Passphrase is a state-of-the-art technology that is at the upper limits of global
standards in terms of accuracy metrics. It differentiates from the competing products in
the market in six aspects. First, background noise level is automatically detected via
proprietary technology and if the level is too high, the enrollment is rejected and the
customer is instructed accordingly. Second, the uttered passphrase is checked through
speech recognition technology, which enables the rejection of phrases different from the
prompted phrase.

Third, for implementations in high-security demanding sectors such as the
finance sector, two separate voiceprints one for cellular and one for landline
channels are embedded in the system to provide a higher level of accuracy.
Fourth, each authentication is used as a feed to the current model, which
continuously increases adaptability and accuracy. Fifth, gender detection
feature can be added to Voice Biometrics solutions. And finally, the solution
is designed to be easily integrated with IVR platforms, back-end enterprise
systems and databases.

How Does Vocal Passphrase Empower Your Business?
The system empowers your business in three fundamental ways:
Improved call center safety and more effective fraud & identity theft
protection
Reduced costs as a result of reduced call duration
Enhanced customer experience

More Than 1.5 Million Registered Voiceprints in AVEA GSM Operator
In 2011 SESTEK Vocal Passphrase was deployed at
the AVEA Call Center, one of the leading GSM
operators in Turkey. AVEA has a nationwide
customer base of 12.8 million as of the first quarter
of 2012. Offering services to 98% of Turkey's
population through its next generation network,
the company is growing fast both in the corporate
and individual services with the brand "AVEA" and
constantly investing in technology and infrastructure
as well as its organizational structure.
Before the implementation of Vocal Passphrase, AVEA Call Center used to verify
identities of customers via a manual agent-assisted security procedure. Since the call
center receives thousands of calls each day, manual verification method was causing
considerable loss of time, increased costs and customer dissatisfaction. After the
implementation of Vocal Passphrase, customers began to use voiceprints to access
AVEA call center and in the first year the number of registered voiceprints reached 1
million. Call duration is shortened by 15 seconds with a minimum of $ 250.000 annual
saving. Today 1 out of every 5 callers of the AVEA contact center uses vocal passphrase
procedure and SESTEK’s implementation in AVEA has become one of the top-5
applications in the global market in terms of its enrollment size with its approximately
2M enrolled users.

TECHNICAL FEATURES
Vocal Passphrase system works in a distributed computing architecture. There are
four server roles in the system. These are Main Vocal Passphrase Server, Vocal
Passphrase Analysis Server, Database Server and Storage Server. The system also has
document encryption and error reporting with SNMP trap features. The product's
interface is provided as a web service to the clients.

TECHNICAL REQUIREMENTS
For ideal modeling, passphrase recordings must be collected in two sessions. In
the first session 200 passphrase recordings of distinct people are collected (half from
fixed line from three different phones and half from mobile line from three different
phones) and in the second session 100 people from the same group of 200 people
generate 100 passphrase recordings (again half from fixed line from three different
phones and half from mobile line from three different phones). Passphrase recordings
are comprised of 5 repetitions of a fixed passphrase such as “my voice is my password”
uttered to the IVR on the phone number provided by SESTEK.
Windows server
Provision of MSSQL server and storage server

LICENCING

Vocal Passphrase product uses SESTEK License Service. Licensing is usage-based. Each
successful enrollment and authentication is charged. If a voiceprint is deleted and
recreated for the same user, it is counted as a distinct enrollment.

Passphrase Performance
Call + 9 0 212 276 25 45 for English.
Call + 9 0 850 250 01 55 for Arabic.
Dial any 6-digit account number which will be your user code and follow the instructions
of the IVR.
The IVR will ask you to repeat this utterance three times: “My voice is my password.”
Utter the sentence to the headset (do not use speaker phone).
After this step your voiceprint is defined and enrollment process is successfully done.
If you continue with the authentication (by pressing 1) or if you make another call
typing the same account number, you will utter the passphrase once and the system
will recognize you from your voiceprint.
Please check if anyone else can enter the system via her voice with the same user
code!

SPEECH ENABLED PASSWORD RESET
Password reset is one of the routine IT tasks that consume time and energy of the
help-desk staff. SESTEK Speech Enabled Password Reset allows employees to reset
their passwords using their voiceprint via any telephone. This self-service procedure
is not only more practical and efficient but also more secure, since the verification is
based on the person’s biometrics rather than some information.
Key Benefits
Cost reduction via self-service
Round-the-clock service liberated from the IT team availability
Higher security due to automation and biometric verification
Configurable security policies
Better legislation compliance
Better employee experience
Scalability
Instant ROI

SPEECH ENABLED SECOND FACTOR AUTHENTICATION
Many customers avoid using credit and debit cards due to real or imagined fraud risks.
SESTEK Speech Enabled Second Factor Authentication virtually eliminates all risks of
fraud by authorizing specified transactions through voice biometrics. The moment
customers initiate any transaction the system makes an outbound call to the user
registered phone number for a voiceprint authentication. Even SMS verification can
be risky in such cases where the cell phone and credit card is taken by a defrauder.
Voice biometrics, however, cannot be faked.
Key Benefits
Higher security
Increased trust in transactions and customer satisfaction
High ROI

VERIFICATION ON-THE-GO
SESTEK Verification On-the-Go verifies a caller’s identity during the conversation. The
technology is based on the comparison of the characteristics of the customer’s voice
to the voiceprints in the database which are formed on-the-go without the requirement
of a passphrase. The accuracy ratio of Verification On-the-Go is relatively lower than
that of Vocal Passphrase, but it serves the needs of many application areas.
Basic Features
Language, accent and content independence
Integration with CRM, CTI and workstation
Key Benefits
Fraud detection
Enhance customer experience
Decreased call duration & increased contact center efficiency

BLACKLIST IDENTIFICATION
Blacklist Identification is used by public security officials in order to identify individuals
of interest for crime prevention. SESTEK Blacklist Identification system can enroll
voiceprints of individuals under investigation and identify listed individuals via their
voice.
Key Benefits
Empowered investigation & crime prevention
Secure communication in critical environments

MOBILE DEVICE AUTHENTICATION
SESTEK Mobile Device Authentication is an application of Vocal Passphrase for mobile
devices.
Key Benefits
Increased security
Increased productivity
Better mobile experience
