EmoNet: Speaker-Aware Transformers for Emotion Recognition — and What I’d Build Differently in 2026

The authors present a retrospective on their 2019 MS thesis, EmoNet, a speaker-aware transformer model for emotion recognition, which achieved a leaderboard ranking of 2nd on the IEMOCAP dataset. Since its inception, the field has undergone significant changes with the rise of large language models (LLMs), which have reshaped the approach to emotion recognition. The authors reflect on what they would build differently today, considering the advancements in LLMs and their impact on the field. This work highlights the importance of adapting to emerging technologies and the evolving landscape of AI research.
