iMiGUE-Speech: A Spontaneous Speech Dataset for Affective Analysis
This provides a resource for researchers studying spontaneous affective states in speech, though it is incremental as an extension of an existing dataset.
The authors introduced iMiGUE-Speech, a spontaneous speech dataset for affective analysis, capturing emotions from real match outcomes, and established benchmarks for speech emotion recognition and sentiment analysis using pre-trained models.
This work presents iMiGUE-Speech, an extension of the iMiGUE dataset that provides a spontaneous affective corpus for studying emotional and affective states. The new release focuses on speech and enriches the original dataset with additional metadata, including speech transcripts, speaker-role separation between interviewer and interviewee, and word-level forced alignments. Unlike existing emotional speech datasets that rely on acted or laboratory-elicited emotions, iMiGUE-Speech captures spontaneous affect arising naturally from real match outcomes. To demonstrate the utility of the dataset and establish initial benchmarks, we introduce two evaluation tasks for comparative assessment: speech emotion recognition and transcript-based sentiment analysis. These tasks leverage state-of-the-art pre-trained representations to assess the dataset's ability to capture spontaneous affective states from both acoustic and linguistic modalities. iMiGUE-Speech can also be synchronously paired with micro-gesture annotations from the original iMiGUE dataset, forming a uniquely multimodal resource for studying speech-gesture affective dynamics.
