New framework decodes modality contributions in audio-visual speech recognition

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Dr. SHAP-AV, a framework utilizing Shapley values to analyze how audio-visual speech recognition models balance acoustic and visual information. Experiments across six models and varying noise levels show that while models increase visual reliance in noisy conditions, audio contributions remain significant. The analysis also revealed that modality balance shifts during speech generation and that signal-to-noise ratio is the primary driver of modality weighting, indicating a persistent audio bias in current models.

    Dr. SHAP-AV: Decoding Relative Modality Contributions via Shapley Attribution in Audio-Visual Speech Recognition

    arXiv:2603.12046v2 Announce Type: replace-cross Abstract: Audio-Visual Speech Recognition (AVSR) leverages both acoustic and visual information for robust recognition under noise. However, how models balance these modalities remains unclear. We present Dr. SHAP-AV, a framework us…
