Text-Driven Emotionally Continuous Talking Face Generation
Unlocking Emotional Nuance in Digital Communication
Revolutionizing Talking Face Generation with Text-Driven Emotional Continuity
Executive Impact & Key Findings
This research pioneers Emotionally Continuous Talking Face Generation (EC-TFG), a novel approach enabling digital avatars to express dynamic, natural emotions directly from text descriptions. It moves beyond static emotional labels to achieve human-like emotional fluidity, significantly enhancing realism and applicability in sectors like virtual reality, entertainment, and advanced customer service.

New Task Definition
Introduces Emotionally Continuous Talking Face Generation (EC-TFG), a novel task that aims to synthesize videos where a person speaks text while reflecting continuously varying emotions from a description, overcoming limitations of fixed emotion labels.

The EC-TFG task is a significant departure from prior audio-driven emotional TFG, shifting the driving input from audio to text for enhanced controllability and editability. It allows for free-form emotion descriptions instead of fixed labels, enabling finer-grained emotional control and dynamic emotional fluctuations aligned with spoken content.
Methodology
Proposes Temporal-Intensive Emotion Modulated Talking Face Generation (TIE-TFG), a customized diffusion model framework. It integrates an emotional Text-To-Speech (TTS) module, a Temporal-Intensive Emotion Fluctuation Predictor, and an emotion-guided visual synthesis module to generate emotionally coherent videos.
TIE-TFG Enterprise Process Flow
The framework leverages a pre-trained TTS model (GLM-4-Voice) for emotional audio generation, then extracts textual and audio features. These are fed into the Temporal-Intensive Emotion Fluctuation Predictor to determine word-level emotion labels and intensities. Finally, a diffusion-based visual synthesis module, enhanced by ReferenceNet and Motion Guide, combines audio and emotion features to generate the video.
Performance & Evaluation
Introduces EC-HDTF, a new dataset with over 10 hours of emotional videos, and the Emotional Fluctuation Score (EF-score) metric. TIE-TFG significantly outperforms existing methods in EF-score, FID, FVD, and Emo-Acc, demonstrating superior ability to capture and transition emotions.

The quantitative results across HDTF and MEAD datasets confirm TIE-TFG's superiority. User studies also show higher scores for overall naturalness, emotion control accuracy, and effectiveness of emotion fluctuation compared to baselines, validating its alignment with human perception.
Challenges & Future Work
Identifies challenges in handling conflicting emotional inputs and the limitations of current emotional TTS models. Future work will focus on improving robustness to complex emotional descriptions and enhancing the overall emotional coherence in generated content.
Emotion Conflict Handling: A Critical Area
Problem: When input modalities contain conflicting emotional cues (e.g., 'angry' description with 'happy' text or smiling reference image), the model's control may fail, leading to inconsistent outputs. While stable emotion descriptions can override minor conflicts, complex, incompatible emotion descriptions are problematic.
Solution Potential: Future advancements must focus on robust conflict resolution mechanisms and ensuring stronger emotional coherence across all input modalities to achieve truly natural and adaptable emotional talking faces.
Key Takeaway: Emotional coherence across all inputs is paramount for robust EC-TFG.
