Jo Lernout - Belgian Entrepreneur and Speech Technology Innovator
Jozef Albert "Jo" Lernout is a Belgian entrepreneur and a pioneering figure in the field of speech and language technology. In 1987, he co-founded Lernout & Hauspie Speech Products (L&H), creating a company that became a global leader in speech recognition, text-to-speech, and language translation technologies throughout the 1990s.
Jo Lernout's contributions to the tech industry have been widely recognized with several prestigious awards. In 1997, he was honored with the Trends Manager of the Year Award and the Flanders Manager of the Year Award. Additionally, he was named the third Flemish entrepreneur of the 20th century, as one of only three, by the Economic Editorial Team of De Standaard.
L&H played a pivotal role in the advancement of human-computer interaction, creating technologies that enabled computers to understand and process human language. Their innovations found applications across various domains, including voice recognition software, translation services, and assistive technologies designed for individuals with disabilities. At its peak, L&H was recognized by The Economist in a special report titled "Who Will Win the Race in the Field of Language Technologies and Artificial Intelligence in the Coming Decade?" as the dominant player in the market, boasting a 70% market share. This positioned L&H ahead of major competitors like AT&T, Microsoft, Apple, and IBM—long before companies like Google had made their mark and even before Facebook existed.
Before establishing Lernout & Hauspie, Jo Lernout gained valuable experience in various roles across the technology and pharmaceutical sectors. He held sales positions at Merck Sharp & Dohme in Belgium and Bull Computers, where he honed his skills in the tech industry. He also served as the marketing director at Wang (Belgium) and as the general manager at Barco Industries Inc. in the U.S. These roles provided him with a solid foundation in both business and technology, which he leveraged in his later endeavors.
Under Lernout's leadership, Lernout & Hauspie made significant strides in developing innovative speech recognition solutions that revolutionized the industry. The company's success attracted notable attention and support, including a significant investment from Bill Gates, co-founder of Microsoft. This investment underscored the innovative potential of Lernout & Hauspie technologies and helped propel the company to new heights. Lernout also shared his expertise as a guest lecturer at universities, world economic meetings, and voice conferences across Europe, Japan, South Africa, and the U.S.
Despite facing legal challenges related to financial misconduct at Lernout & Hauspie, Jo Lernout has consistently maintained his innocence. The company encountered serious difficulties due to these accusations, leading to a significant drop in its share price. Despite possessing hundreds of patents, a wealth of valuable source code, hundreds of top scientists and technology engineers, very large customers, and even a strong written intention (dated December 21, 2000) from Daimler Benz's Temic division to pay 300 million US dollars for embedding all L&H technology in car dashboards—assets that could have saved the company and guaranteed its continued stellar growth—the company went bankrupt in October 2001. This outcome was largely brought about by an inside job aimed at facilitating a reverse acquisition to obtain all these assets for a mere 11 million US dollars.
In addition to addressing past issues, Lernout remains dedicated to advancing technology. His ongoing contributions to the field of artificial intelligence and his efforts to support technological development in Belgium underscore his enduring passion and vision. Jo Lernout's career is a testament to his resilience and commitment to both technological innovation and personal integrity. His ongoing work continues to influence the future of AI and technology, reflecting his dedication to making a positive impact. Lernout’s legacy is a powerful reminder of the importance of innovation and the enduring potential of embracing new technological frontiers.
