PRODIS -- a speech database and a phoneme-based language model for the study of predictability effects in Polish
This provides a foundational resource for phonetic analysis and speech technology in Polish, addressing a gap in publicly available data.
The authors tackled the need for a high-quality Polish speech corpus by creating PRODIS, a large, publicly available database with 90% automated processing, and a phoneme-based language model for studying predictability effects on acoustic parameters.
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.
