## 6 Conclusions and Future Work
* Audio analysis by fragments: Another area of future development is the analysis of audio by short fragments, such as 4-second intervals, to detect possible manipulations within long audios. This technique will allow us to identify false fragments inserted into authentic recordings, increasing the precision and reliability of our verification tools. * Multidisciplinary collaboration: We will continue to strengthen collaboration with universities, research centers, and technology companies to enrich our methodologies and tools, ensuring a diversity of perspectives and knowledge.

All authors have read and agreed to the published version of the manuscript. This study is part of the project IVERES (PLEC2021-008176), financed by MCIN/AEI/10.13-039/501100011033 and by the European Union \"NextGenerationEU\"/PRTR and the RTVE-UGR Chair in Deep Speech Synthesis and Conversational AI and its Applications in News Verification ([[https://catedartartve.ugr.es/](https://catedartartve.ugr.es/)]([https://catedartartve.ugr.es/](https://catedartartve.ugr.es/))). IVERES has been funded by the Spanish Ministry of Science and Innovation belonging to the 2021 call, R&D&I projects in strategic lines in public-private collaboration, of the state program of R&D&I oriented to the challenges of society in the framework of the State Plan for Scientific and Technical Research and Innovation 2017-2020. Not applicable. The ASVSpoof dataset is available in [[https://zenodo.org/records/48](https://zenodo.org/records/48)]([https://zenodo.org/records/48](https://zenodo.org/records/48)) 37263. The real recordings of the voices of the Spanish politicians used in the RTVE-UGR Chair were downloaded from the Spanish Congress website [[https://www.congreso.es/es/archivo-audiovisual](https://www.congreso.es/es/archivo-audiovisual)]([https://www.congreso.es/es/archivo-audiovisual](https://www.congreso.es/es/archivo-audiovisual)). The synthetic voices generated in the Chair cannot be shared following research ethics commitments. The authors would like to thank [PERSON] for his implication in the successful deployment of the models. We are also grateful to Loccus.ai, especially [PERSON], for their collaboration to integrate their voice fake detection software into the verification tool of the RTVE-UGR Chair. Conflicts of Interest: Authors [PERSON], [PERSON], [PERSON] and [PERSON] were employed by the company RTVE. [PERSON] and [PERSON] were employed by the company Monoceros Labs. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
