PhpHMM Tool for Generating Speech Recogniser Source Codes Using Web Technologies

This paper deals with the “phpHMM” software tool, which facilitates the development and optimisation of speech recognition algorithms. This tool is being developed in the Speech Processing Group at the Department of Circuit Theory, CTU in Prague, and it is used to generate the source code of a speech recogniser by means of the PHP scripting language and the MySQL database. The input of the system is a model of speech in a standard HTK format and a list of words to be recognised. The output consists of the source codes and data structures in C programming language, which are then compiled into an executable program. This tool is operated via a web interface.
