abstract

The availability of large, high-quality emotional speech databases is essential for advancing speech emotion recognition (SER) in real-world scenarios. However, many existing databases face limitations in size, emotional balance, and speaker diversity. This study describes the MSP-Podcast corpus, summarizing our ten-year effort. The corpus consists of over 400 hours of diverse audio samples from various audio-sharing websites, all of which have Common Licenses that permit the distribution of the corpus. We annotate the corpus with rich emotional labels, including primary (single dominant emotion) and secondary (multiple emotions perceived in the audio) emotional categories, as well as emotional attributes for valence, arousal, and dominance. At least five raters annotate these emotional labels. The corpus also has speaker identification for most samples, and human transcriptions of the lexical content of the sentences for the entire corpus. The data collection protocol includes a machine learning-driven pipeline for selecting emotionally diverse recordings, ensuring a balanced and varied representation of emotions across speakers and environments. The resulting database provides a comprehensive, high-quality resource, better suited for advancing SER systems in practical, real-world scenarios.

SHALA-LLM: Smartly Handling Ambiguous Labels in Aligning LLMs

cs.LG · 2026-06-03 · unverdicted · novelty 6.0

SHALA-LLM is a new RL framework for LLM alignment that learns directly from annotator label distributions and prioritizes ambiguous samples, reducing Jensen-Shannon Distance by up to 62.1% and raising F1 by up to 16.7% on NLI and ER benchmarks.

Multimodal Hidden Markov Models for Persistent Emotional State Tracking

cs.AI · 2026-05-13 · unverdicted · novelty 5.0

Sticky factorial HDP-HMMs applied to multimodal valence-arousal trajectories identify interpretable persistent emotional regimes in conversations, outperforming Gaussian HMM baselines in consistency metrics and enabling context-augmented LLM responses.
