As GVZ Speech Technologies Co., we are a multilingual Speech Recognition, Text-to-Speech, Voice Authentication and Natural Language Processing technologies vendor company.

We are proud to state that we are the first (and currently the only) company that implemented speech technologies projects in Turkey and Turkish Language. Please find some of the projects that we have installed below:

-          Turkcell (the largest GSM operator in Turkey with more than 14 millon subscribers) Voice Portal Project;

-          ARIA (the third largest GSM operator in Turkey) Unified Messaging Project, SMS-to-Speech Project;

-          Biletix (the largest ticket sales company in Turkey) Movie Ticket Sales Line;

-          Kocbank (one of the largest private banks in Turkey) Stock Quotes System;

-          Turk.Net (one of the larges ISPs in Turkey) Unified Messaging System;

-          KocNet (largest enterprise ISP in Turkey) Unified Messaging System;

-          Arcelik (largest home appliances producer in Turkey) Intelligent Home Project;

-          Turkish Airlines (largest airlines company in Turkey);

  100% of the source codes are produced by our engineers and the Intellectual Property Rights of our technologies are owned b our company. I would like to list the issued patents of our company, to give you an impression regarding the know how of our company:

-          Adaptive Weiner filtering using a dynamic suppression factor'', Issued Jan 6, 1998. U.S. Patent No: 5,706,395.

-          Method of out of vocabulary word rejection Issued June 5, 2001. U.S. Patent No: 6,243,677.

-          Adaptive Weiner filtering using line spectral frequencies, Issued July 17, 2001. U.S. Patent No: 6,263,307.

-          Voice Conversion by Segmental Codebook Mapping of Line Spectral Frequencies and Excitation, Filed 1997

-          Face Synthesis System and Methodology, Issued September 10, 2002. U.S. Patent No: 6,449,595.

-          Speech Conversion System and Method, Filed 2000.

In this perspective with our huge know how in Speech Technologies (Speech Recognition, Text-to-Speech, Speaker Verification, Language Understanding, Keyword Spotting, Voice Activity Detection, Voice Suppression, Speech Conversion etc) we will add a great value to the project.
