This paper summarizes the process of validating RekEmozio, a multilingual (Spanish and Basque) and multimodal (audio and video) affective database. Fifty-seven participants validated a sample of 2,618 videos of facial expressions and 102 utterances in the database. The results replicated previous findings of no significant differences in recognition rates among emotions. This validation has allowed having the audio and video material in the database classified in terms of the emotional category expressed. This normative data has proven to be usefulfor both training affective recognizers and synthesizers and carrying out empirical studies on emotions by psychologists.
