In this paper we present a strategy, current activities and results of a joint project in designing a spoken dialog system for Slovenian and Croatian weather information retrieval. We give a brief description of the system design, of the procedures we have performed in order to obtain domain specific speech databases, monolingual and bilingual speech recognition experiments and WOZ simulation experiments. Recognition results for Croatian and Slovenian speech are presented, as well as bilingual speech recognition results when using common acoustic models. We propose two different approaches to the language identification problem and show recognition results for the both acoustically similar languages. Results of dialog simulations, performed in order to gain user behaviors when accessing a spoken dialog system, are also presented.
