Information Technology at the TU Dresden goes back to Heinrich Barkhausen (1881–1956), the “father of the electron valve“, who taught from 1911 to 1953. Speech research in a narrower sense started with the development of a vocoder in the 1950s. Walter Tscheschner (1927–2004) performed his extensive investigations on the speech signal using components of the vocoder. In 1969, a scientific unit for Communication and Measurement was founded in Dresden. It is the main root of the present Institute of Acoustics and Speech Communication. W. Tscheschner was appointed Professor of Speech Communication and started with research in speech synthesis and recognition, which today continues.
Numerous objects from the history of Speech Communication in Dresden, but also from other parts of Germany, are preserved at the historic acoustic-phonetic collection of the TU Dresden. Until the opening of Interspeech 2015, we will present interesting exhibits from the collection in this newsletter monthly. Today, we give an introduction. 
The historic acoustic-phonetic collection of the TU Dresden consists of three parts:
The collection is presented in the Barkhausenbau at the main campus of the TU Dresden (cf. Figure 1). Recently, it is moving to new rooms which are more convenient for the presentation. The newly installed collection will be re-opened at the opportunity of Interspeech 2015.

For this purpose, we cordially invite to a workshop on the history of speech communication, called HSCR2015, which will be held as a satellite event of Interspeech 2015 at September 4/5, 2015, in the Technical Museum of the City of Dresden. It is organized by the special interest group (SIG) on "The History of Speech Communication Sciences", which is supported by the International Speech Communication Association (ISCA) and the International Phonetic Association (IPA).
Rüdiger Hoffmann is with the Technische Universität Dresden.
