The Ph@ttSessionz speech database, funded by the German Ministry of Science and Education (BMBF), contains recordings of 864 adolescent speakers of German (age range 12-20). The recordings were performed via the WWW in public schools (Gymnasium) in 41 locations in Germany. The speech material recorded is a superset of the German SpeechDat-II and RVG-I corpora (see also ELRA-S0051, S0058, S0063, S0096 and S0155). Recordings were done with SpeechRecorder in selected schools in the years 2005-2007. Both channels, the headset and the desktop microphone, were recorded in high quality.
