Finnish Speechdat(II) FDB-1000
The Finnish SpeechDat(II) FDB-1000 comprises 1000 Finnish speakers (617 males, 383 females) recorded over the Finnish fixed telephone network. The FDB-1000 database is partitioned into 4 CDs, 3 CDs comprise 300 speakers sessions, the 4th comprises 100 speakers sessions. The speech databases made within the SpeechDat(II) project were validated by SPEX, the Netherlands, to assess their compliance with the SpeechDat format and content specifications.
