What did they say about us?

“Customer satisfaction is a priority for TEB. This is why we attach great importance to innovative technologies that help us understand our customers’ needs in order to provide them with faster and more practical solutions. Sestek Speech Enabled IVR removes complicated DTMF menus from traditional IVR systems, routes callers to the right destination in less time, and allows them to complete their transactions with ease. Our customers’ quick adaptation to the technology serves as a testimony to the benefits.”

Özge TekalpHead of TEB BNP Paribas Joint Contact Center

“We implemented Vocal Passphrase technology at Turkish Telecom Contact Center to
allow our customers securely and easily complete various transactions without losing
time with traditional security questions. When we decided to carry out this project,
Vocal Passphrase was a new technology and choosing the right technology provider
was an important decision to make. Sestek’s expertise in the speech technology
field and continuous R&D efforts played an important part in our decision. Rapid
increase in the number of registered voice prints and positive feedback we get from
our customers prove that we made the right decision.”

Eniz AkdağTurkish Telecom Call Center

“As a result of our quality approach, we closely follow developments in technology
in order to deliver improved services. Implementing Sestek Speech Analytics in our
call center helped us obtain crucial data that directly influences our performance
management. Since we see Sestek as a partner rather than a vendor, we engaged in
interactive communication during the project. Our continuous feedback contributed
to the development of new modules for Sestek Speech Analytics.”
