In this paper we present Indonesian Emotional Speech Corpus (IDESC), the first ever corpus in Indonesian that contains various emotion contents. As interaction between human and computer makes its way to the most natural form possible, it becomes more and more urgent to incorporate emotion in the equation. However, in Indonesian, this aspect is yet to be explored. The acquisition of an emotion corpus serves as a foundation in further research regarding the subject. In constructing IDESC, we aim at natural and real emotion that is applicable to human-computer interaction. The corpus consists of three episodes of Indonesian talk show in different genres: politics, humanity, and entertainment. Each episode is carefully segmented and labeled based on its emotion content, resulting in 2179 segments worth 1 hour, 34 minutes, and 49.7 seconds of speech. The corpus is still in its early stage of development, yielding exciting possibilities of future works.
