Speaker recognition and the ETSI Standard Distributed Speech Recognition Front-End

With the advent of Wireless Application Protocol (WAP) and 2.5/3G communication systems, the mobile device has become a window to the Internet. A natural interface to this mobile device is through speech. To address this need, a new European Telecommunications Standards Institute (ETSI) standard front-end has evolved for Distributed Speech Recognition (DSR). The goal of the ETSI DSR front-end is to standardize client-server speech recognition applications with a common feature set and quantization method. Although originally evolved as a speech recognition standard, we propose it is also a method of standardizing distributed speaker recognition authentication. To this end, we perform experiments using the DSR parameterization for a speaker recognition application. Results indicate excellent preservation of speaker identity in the DSR standard. This testing shows that DSR brings the potential for a promising new era of portable authentication for applications in personalization and security.
