Vocal Passphrase is a groundbreaking biometric technology that defines themodern concept of identity verification. Conventional security systems arebased on PINs, passwords and challenge questions which are not onlyinefficient for growing incidence of fraud and identity theft but also causewaste 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 authenticatedthrough this voiceprint. The solution can be applied in a variety of flexible ways accordingto the needs of the customer such as a single layer or an additional layer of security to thestandard security procedures.

SESTEK Vocal Passphrase is a state-of-the-art technology that is at the upper limits of globalstandards in terms of accuracy metrics. It differentiates from the competing products inthe market in six aspects. First, background noise level is automatically detected viaproprietary technology and if the level is too high, the enrollment is rejected and thecustomer is instructed accordingly. Second, the uttered passphrase is checked throughspeech recognition technology, which enables the rejection of phrases different from theprompted phrase.



The system empowers your business in three fundamental ways:

Improved call center safety and more effective fraud & identity theftprotection

Reduced costs as a result of reduced call duration

Enhanced customer experience

Fifth, gender detectionfeature can be added to Voice Biometrics solutions.

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.

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.

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
