Utsunomiya University Spoken Dialogue Database for Paralinguistic Information Studies — UUDB

The Utsunomiya University (UU) Spoken Dialogue Database for Paralinguistic Information Studies (UUDB) is a collection of spontaneous and expressive dialogue speech.

Paralinguistic information is a term referring to some meaningful information along with spoken language, which may include speaker's emotional states, attitudes, and intentions.

One of the most remarkable features of the UUDB is that it comes with labels of perceived emotional states for all utterances. Because the nature of paralinguistic information evaluation in terms of consistency and agreement has well been studied, users can make use of UUDB's paralinguistic information labels as data reliable at a certain level.

Currently, UUDB's release has two versions:

UUDB Release 1
