MobilDat-SK - a Mobile Telephone Extension to the SpeechDat-E SK Telephone Speech Database in Slovak

The paper describes design and process of collection, annotation and evaluation of a new Slovak mobile-telephone speech database MobilDat-SK, which is a mobile-telephone extension to the SpeechDat-E SK. The MobilDat-SK database contains recordings of 1100 speakers and it is balanced according to the age, accent, and sex of the speakers. Every speaker pronounced 50 files (either prompted or spontaneous) containing numbers, names, dates, money amounts, embedded command words, geographical names, phonetically balanced words, phonetically balanced sentences, Yes/No answers and one longer non-mandatory spontaneous utterance. In the paper the structure of the database, the hardware and software solution of the automatic recording, the speaker recruitment strategy, the annotation process and evaluation process are described. The MobilDat-SK database has been developed for the “Intelligent Speech Communication Interface” project in the frame of the State Research and Development Task “Building the Information Society”.
