About AQL

About the Conference

The International Conference on Advances in Quantitative Laryngology, Voice, and Speech Research (AQL) brings together scientists, clinicians, engineers, and trainees from around the world to share theoretical, experimental, methodological, and clinical advances in voice and speech research.

AQL promotes interdisciplinary exchange and collaboration in the development of quantitative approaches to investigating laryngeal function, voice production, and spoken communication. The conference welcomes participants from fields including otolaryngology, speech-language pathology, communication systems, engineering, acoustics, biomechanics, biology, physics, and related disciplines.

History of AQL

The first AQL meeting was held in Erlangen, Germany, in 1996. It began as a collaborative research workshop where European voice laboratories could share progress, compare methods, and establish new goals related to the quantitative assessment of laryngeal function, voice, and speech.

During its first several years, the AQL initiative expanded rapidly in both participation and international recognition. The first four meetings were organized as research workshops, beginning with approximately 15 participants and growing to approximately 50 participants by 2000. The fifth AQL, held in Groningen in 2001, marked its development into an international conference, attracting participants from around the world.

Subsequent AQL conferences were hosted across Europe, North America, Asia, and South America. Student workshops were added to the conference in 2010 to support education, scientific exchange, and the professional development of emerging voice researchers. In 2013, AQL was held outside Europe for the first time in Cincinnati, Ohio. The conference later expanded to the Asia-Pacific region with AQL 2017 in Hong Kong and to South America with the virtual AQL 2021 meeting hosted in Bogotá, Colombia.

Today, AQL continues to provide an international and interdisciplinary forum for advancing quantitative methods to laryngeal function, voice, and speech research.
