The text aims to remember Armando de Lacerda’s pursuit in implementing experimental phonetic techniques in various universities, with special emphasis on the establishment, in Brazil, of the 1st Experimental Phonetics Laboratory of South America, in 1956, at the then School of Philosophy of 'Universidade da Bahia', in the city of Salvador. The setting up of this Laboratory was due to the interest of Rector Edgard Santos and to the meeting of the Portuguese phonetician Armando de Lacerda with Professor Nelson Rossi, invited to give classes at 'Universidade da Bahia'. Among Armando de Lacerda’s main activities, registered during the six months in which he remained in Bahia, were the presentation of the chromographic method and the introduction to notions of phonetic transcription, with the use of the Lacerda-Hammarström system, as well as dialectal researches in the cities of Juazeiro (Bahia) and Petrolina (Pernambuco). It is important to highlight the legacies from the Phonetics Laboratory, such as the establishment of a Sound Archive and the formation of researchers, which gave rise to Dialectology in Brazil, with the preparation of the first linguistic atlas, 'Atlas prévio dos falares baianos', in 1963. The Phonetics Laboratory, mainly after 1968, began suffering from lack of personnel and funding. In 1986, the installations were prematurely abandoned, after an accident in the physical structure of the building where it was located and which was later destroyed by fire.
