VeriDat Speaker Verification Corpus - VERIF1DE

Last Update: 2012-04-20 -- gleiche Seite in Deutsch


The speech corpus VERIF1DE contains 20 recordings (session) of 150 German speakers each over the telephone network. Sessions are distributed over a period of time (speakers were not allowed to record more than one session a day, but this was not controlled). Each session contains 40 single recordings, mainly speech read from a prompt sheet. The acoustic environment is classified into quiet (14) and noisy (6); the telephone channel is either fixed network (10) or GSM (10). Recorded content is mainly SpeechDat conform extended by some extra items. The corpus has been pre-validated by BAS, then repaired (extra recordings to replace missing items), and then a final validation was performed by SPEX. After the final validation (version 1) the corpus was again repaired to some extend (version 1.3).
