The proposed project follows up the previous research activities carried out in the speech processing area by the team that integrates all Czech research groups which are recently active in speech analysis, synthesis and recognition. It was established in 1996 to participate on an ambitious 6-year project supported by the GACR and later continued in another speech oriented project ending in 2002. Each of the groups involved has its own proficiency in a specific domain, which allows the consortium to work on integrated and complex tasks. In the previous years the team has created large databases of annotated speech recordings, which are now available both training and testing purposes in speech recognition domain as well as for speech synthesis. In addition, a set of powerful tools and platforms for developing own recognition and synthesis systems has been built together with several working prototypes that serve for evaluation and demonstration purposes. Based on this state and with respect to the recent trends in voice technologies, the project will focus on the investigation and implementation of algorithms that are applicable in distributed, embedded and mobile systems, in recognition engines working with very large vocabularies, in TTS modules for interactive communication and information services, in automatic transcription of broadcast news as well as in multimodal audio-visual interfaces. Primarily, the research will address specific needs of Czech.
