Joseph Mariani

Also known as Joseph-Jean Mariani

Joseph Mariani is a computer scientist whose career spans speech recognition, speech communication, and multilingual information systems. He earned a Doctor of Engineering degree from Pierre and Marie Curie University in 1977, led LIMSI's Spoken Communication group from 1982 to 1985, and directed the laboratory from 1989 to 2000. In 1988, he joined ESCA's founding committee and became its first president through 1993; from 2001 to 2006, he directed France's Information and Communication Technologies department, and from 2006 to 2014, he led IMMI. He and his coauthors analyzed 25 years of ISCA Archive papers in 2013; their 2019 NLP4NLP Corpus study examined 65,000 documents from 34 major speech and language processing conferences and journals. Since 2016, he is director of research emeritus at LISN and Research Director Emeritus at CNRS; in June 2026, he introduced the Speech Processing panel at KIT.

From the biography.

  1. 11% of AI doctorate holders from 2010 to 2016 founded or led a company or lab by 10 years after graduationIncludes Joseph Mariani. We estimate how often AI doctorate holders founded or led a company or lab by 10 years after graduation, how waiting times compare between founders and top jobs, and which universities trained the most.
  2. Of 216 AI researchers who entered public life, 83 held advisory seats and 58 took public rolesIncludes Joseph Mariani. Of 216 AI researchers who entered public life, 83 held advisory seats and 58 took public roles. Another 97 people moved from public careers into AI organizations or research, with 62% of dated records starting from 2020 on.
  3. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes CNRS. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  4. Universities keep AI researchers for a median of 6 years, compared with 2 years at frontier labsIncludes CNRS. Across 15,811 dated work stays (6,529 people), median role tenure runs from 6 years at universities to 2 years at frontier labs. We compare all five organization types, starting decades from the 1970s to the 2020s, and the organizations that keep people longest.
