Croatian Speech Technologies

Speech technologies deal with designing computer systems that can recognize spoken words, comprehend human language and generate intelligible speech. There is a wide range of applications speech technology systems were successfully implemented in. One of the most complex applications in speech technology is a spoken dialog system, which can be used for information inquiry services. In the paper we present the work in the development of a spoken dialog system for Croatian language. We propose an approach for development of modules in a spoken dialog system for the limited domain which uses the same acoustic model for speech recognition and speech synthesis. For the linguistic analysis an approach is proposed which is based on qualitative language modelling, while the development of the dialog module is based on the formalism of the object-oriented frame logic language. Some experimental results for Croatian speech recognition and understanding are presented and discussed.
