AI Debate
A political debate simulator grounded in real speeches from the Spanish Parliament, built to compare how Pedro Sánchez and Alberto Núñez Feijóo argue about any topic.

Funded by
Before summer 2024, Emilio Soria sent me a brief, almost one-sentence proposal for a political debate simulator. I developed it into AI Debate as a project funded by Cátedra PAGODA and, ultimately, the Generalitat Valenciana. That project officially ended in September 2024, then I returned to it for my final degree project. From the beginning, I also wanted the debate to sound like its speakers, so I later fine-tuned F5-TTS to clone the voices of Pedro Sánchez and Alberto Núñez Feijóo.
Approach
- Built a RAG pipeline over real parliamentary speeches so each politician's answers draw from their own arguments, rhetoric, and positions.
- Designed the multi-agent debate flow, including the two political agents, turn-taking, and a moderator.
- Fine-tuned an F5-TTS model for Sánchez and Feijóo, starting from Juan Pablo Gallego's Spanish checkpoint.
Impact
- Presented the funded project to the Generalitat Valenciana and, on October 22, 2024, at IDAL's event The Large Language Model Revolution.
- Expanded the project into my final degree project and received the Best Final Degree Project Award.
- Published the work with Emilio Soria, Joaquín Martín, and Jorge Castellanos in Intelética.
