PRODIS -- a speech database and a phoneme-based language model for the
  study of predictability effects in Polish
Zofia Malisz Jan Foremski Małgorzata Kul
We present a speech database and a phoneme-level language model of Polish.
The database and model are designed for the analysis of prosodic and discourse
factors and their impact on acoustic parameters in interaction with
predictability effects. The database is also the first large, publicly
available Polish speech corpus of excellent acoustic quality that can be used
for phonetic analysis and training of multi-speaker speech technology systems.
The speech in the database is processed in a pipeline that achieves a 90%
degree of automation. It incorporates state-of-the-art, freely available tools
enabling database expansion or adaptation to additional languages.
