    METANET4U is a European project aiming at supporting language technology for European languages and multilingualism. It is a project in the META-NET Network of Excellence, a cluster of projects aiming at fostering the mission of META, which is the Multilingual Europe Technology Alliance, dedicated to building the technological foundations of a multilingual European information society. This paper describe the resources produced at our lab to provide Synthethic voices. Using existing 10h corpus for a male and a female Spanish speakers, voices have been developed to be used in Festival, both with unit-selection and with statistical-based technologies. Furthermore, using data produced for supporting research on intra and inter-lingual voice conversion, four bilingual voices (English/Spanish) have been developed. The paper describes these resources which are available through META. Furthermore, an evaluation is presented to compare different synthesis techniques, influence of amount of data in statistical speech synthesis and the effect of sharing data in bilingual voices.

    This paper presents a web-based multimedia search engine built within the Buceador (www.buceador.org) research project. A proof-of-concept tool has been implemented which is able to retrieve information from a digital library made of multimedia documents in the 4 official languages in Spain (Spanish, Basque, Catalan and Galician). The retrieved documents are presented in the user language after translation and dubbing (the four previous languages + English). The paper presents the tool functionality, the architecture, the digital library and provide some information about the technology involved in the fields of automatic speech recognition, statistical machine translation, text-to-speech synthesis and information retrieval. Each technology has been adapted to the purposes of the presented tool as well as to interact with the rest of the technologies involved.

    During the preparation of the METANET4U proposal, partners elaborated a list of language resources, including both data and software, which could be made available for the purposes of the project. The data was prepared by all partners and was included in Appendix A of the Annex 1 of the contract. The objective of this Deliverable D2.1 Report on first seletion of resources is to select the resources that will be prepared in WP3 and delivered in month M10 as a first batch of resources (Batch 1). The remaining language resources will be delivered either in the second batch during month 18 (M18) (Batch 2), or in the third batch during month 24 (M24) (Batch 3). The decision of whether to deliver in Batch2 or Batch 3 will be taken in Task 2.3 in deliverables 2.4 and 2.5. This deliverable is organized as follows: section 2 explains the way in which language resources are described and categorised, while section 3 shows, for each partner, the resources that will be delivered in Batch 1 and the resources that will be delivered in subsequent batches. Section 4 contains a list of the language resources that, at this stage of the project, partners are willing to deliver. This list is an updated version of the original list of the Annex 1 of the contract.

    The central objective of the Metanet4u project is to contribute to the establishment of a pan-European digital platform that makes available language resources and services, encompassing both datasets and software tools, for speech and language processing, and supports a new generation of exchange facilities for them.

    In this paper, we present a multilingual database specifically designed to develop technologies for rich audio-visual scene description in meeting-room environments. Part of that database includes the already existing CHIL audio-visual recordings, whose annotations have been extended. A relevant objective in the new recorded sessions was to include situations in which the semantic content can not be extracted from a single modality. The presented database, that includes five hours of rather spontaneously generated scientific presentations, was manually annotated using standard or previously reported annotation schemes, and will be publicly available for the research purposes.

    This paper presents our work around the FESTCAT project, whose main goal was the development of voices for the Festival suite in Catalan. In the first year, we produced the corpus and the speech data needed for build 10 voices using the Clunits (unit selection) and the HTS (Markov models) methods. The resulting voices are freely available on the web page of the project and included in Linkat, a Catalan distribution of Linux. More recently, we have updated the voices using new versions of HTS, other technology (Multisyn) and we have produced a child voice. Furthermore, we have performed a prosodic labeling and analysis of the database using the break index labels proposed in the ToBI system aimed to improve the intonation of the synthetic speech.

    In this paper, multidialectal acoustic modeling based on shar- ing data across dialects is addressed. A comparative study of different methods of combining data based on decision tree clustering algorithms is presented. Approaches evolved differ in the way of evaluating the similarity of sounds between di- alects, and the decision tree structure applied. Proposed systems are tested with Spanish dialects across Spain and Latin Amer- ica. All multidialectal proposed systems improve monodialectal performance using data from another dialect but it is shown that the way to share data is critical. The best combination between similarity measure and tree structure achieves an improvement of 7% over the results obtained with monodialectal systems.
