This paper presents an overview of different approaches for providing Automatic Speech Recognition (ASR) technology to mobile users. Three principal system architectures in terms of employing wireless communication link are analyzed: Embedded Speech Recognition Systems, Network Speech Recognition (NSR) and Distributed Speech Recognition (DSR). Overview of the solutions which became standards by now as well as some critical analysis of the latest developments in the field of the speech recognition in mobile environments is given. Open issues, pros and cons of the different methodologies and techniques are highlighted. Special emphasis is made on the constraints and limitations the ASR applications encounter under the different architectures.
