PERSO Corpus



The PERSO speech database is the result of two research projects: Personalized Hidden Markov Modeling –based Text-To-Speech Synthesis: Assistive Technology for People with Communication Disabilities (funded by Tekes) and Adaptive spatial model for vocal expression: emotional speech synthesis for Finnish (funded by Academy of Finland). The projects were carried out between 2009 and 2012. The speech database was collected in 2011 and 2012. These projects are followed by the international Simple4All speech synthesis project funded by EU.

The purpose of these projects is to create more appropriate speech synthesis options for TTS (Text-To-Speech) conversion applications like assistive communication devices. Speech synthesis products are often generic and their application possibilities are narrow, so there’s a clear need for wider range of synthesis voices and styles. The PERSO corpus consists of single speaker databases with Finnish read and spontaneous speech from 33 men and 33 women, 60 of which are smaller (~ 40 minutes continuous speech/subject) and 6 larger (~ 4 hours of continuous speech/subject) databases. The speech data are packaged with associated text files.

The PERSO corpus will be published at for non-commercial scientific use only.
