Conversational agents have been a research subject of Prof. Dr. Oliver Bendel for a quarter of a century. He dedicated his doctoral thesis at the University of St. Gallen to them. At the School of Business FHNW, he developed them with his changing teams from 2012 to 2022, primarily in the context of machine ethics and social robotics. The philosopher of technology now devotes himself increasingly to dead, extinct, and endangered languages. After @ve (2022), a chatbot for Latin based on GPT-3, another project started in March 2023. The chatbot @llegra is developed by Dalil Jabou for the Rhaeto-Romanic idiom Vallader, which occurs in the Lower Engadine between Martina in the northeast and Zernez in the southwest, as well as in Val Müstair. The user can type text and gets text output. In addition, @llegra speaks with the help of a text-to-speech system from the company SlowSoft, which supports the project. The GPT-3 speech model produced rather unsatisfactory results. The breakthrough then came with the use of GPT-4. The knowledge base was supplemented with the help of four children’s books on Vallader. The project will be completed in August 2023. The results will be published thereafter.
