The historic acoustic-phonetic collection (HAPS) of the TU Dresden documents the history of experimental phonetics and speech technology with a re- markably high degree of completeness. Due to some construction work, the col- lection could move to new and improved showrooms in the Barkhausen Building. This paper is a slightly extended version of the welcome speech, presented at the occasion of the re-opening of the collection in the framework of the First Interna- tionalWorkshop on the History of Speech Communication Research (HSCR 2015), a satellite event of the Interspeech, Dresden 2015.
