Development of a voice-based telephone information system. Actas de las III Jornadas de Tecnologías del Habla, 2004.Speech technologies currently have several applications. One of the most popular applications is telephone-based information services, which are generally based on specific hardware and software solutions. In this paper, we present the development of an inexpensive telephone-based information system that is based on a voice modem and free software, which allows easy construction of information systems for different organisations. This system facilitates the creation and maintenance of language and lexical models for the speech recogniser and copes with the databases of the task. Moreover, the system implements multilingual capabilities for Spanish and Catalan which can be extended to other languages. Some preliminary evaluation results validate the performance of the current prototype.
