Online gaming voice chat corpus with emotional label (OGVC)



Online gaming voice chat corpus with emotional label (OGVC) is an open-access speech corpus containing both spontaneous and acted speech and it’s emotional labels.

This corpus was partially constructed in the course of the Exploratory IT Human Resources Project (The MITOH Youth Program), “Development of anonymous voice chat system for online game (Project leader: Dr. Hiromi Kawatsu),” supported by Information-technology Promotion Agency.

The corpus consists of two speech materials, Naturalistic emotional speech and Acted emotional speech.

Naturalistic emotional speech
This speech material contains 9,114 spontaneous utterances from five dyadic and one triad dialogues. To record spontaneous and NATURALISTIC emotional speech effectively, Massively Multiplayer Online Role-Playing Game (MMORPG) was adopted to stimulate players to express emotion. In addition, a voice chat system was used to record speaker’s spontaneous speech reflected his/her stimulated emotion.

Attention: The naturalistic emotional speech is delivered in a monaural sound file / speaker. You can merged into two monaural sound files into one stereo file
and can listen to it as if two speakers make a chat over the Internet. However, these files dose not includes any network delay, you can not reproduce the actual timing they make a chat.

Acted emotional speech
This speech material contains 2,656 acted utterances spoken by four professional actors (two male and two female). Seventeen short dialogues were selected from the dialogues recorded for the naturalistic emotional speech. The actors were instructed to speak each utterance in the short dialog with a specific emotion in three different levels of emotional intensity.
