The LPL preserves measurement instruments developed since the 1950s and used for research on the production, perception and comprehension of oral and written language. These devices mainly represent instruments for recording and analysis of air flows and pressures, movements and activities of articulating organs, acoustic waves and perceptual responses related to linguistic stimuli. The collection includes about a hundred historic documents and scientific devices. Some are unique and original pieces, designed and manufactured locally by Bernard Teston, research engineer and ancient director of the lab. These constitute emblematic traces of the historical transition from mechanical recording to electronic and then digital recording of the physics of speech and the facts of language.
