Vision Language Models (VLMs) often struggle with culture-specific knowledge, particularly in languages other than English and in underrepresented cultural contexts. To evaluate their understanding of such knowledge, we introduce WorldCuisines, a massive-scale benchmark for multilingual and multicultural, visually grounded language understanding. This benchmark includes a visual question answering (VQA) dataset with text-image pairs across 30 languages and dialects, spanning 9 language families and featuring over 1 million data points, making it the largest multicultural VQA benchmark to date. It includes tasks for identifying dish names and their origins. We provide evaluation datasets in two sizes (12k and 60k instances) alongside a training dataset (1 million instances). Our findings show that while VLMs perform better with correct location context, they struggle with adversarial contexts and predicting specific regional cuisines and languages. To support future research, we release a knowledge base with annotated food entries and images along with the VQA data.

Advancements in technology and the increased use of digital data threaten individual privacy, especially in speech containing Personally Identifiable Information (PII). Therefore, systems that can remove or process privacy-sensitive data in speech are needed, particularly for low-resource transcripts. These transcripts are minimally annotated or labeled automatically, which is less precise than human annotation. However, using them can simplify the development of de-identification systems in any language. In this study, we develop and evaluate an efficient speech de-identification system. We create an Indonesian speech dataset containing sensitive private information and design a system with three main components: speech recognition, information extraction, and masking. To enhance performance in low-resource settings, we incorporate transcription data in training, use data augmentation, and apply weakly supervised learning. Our results show that our techniques significantly improve privacy detection performance, with approximately 29% increase in F1 score, 20% in precision, and 30% in recall with minimally labeled data.
