MSDWild: Multi-modal Speaker Diarization Dataset in the Wild

Speaker diarization in real-world acoustic environments is a challenging task of increasing interest from both academia and industry. Although it has been widely accepted that incorporat-ing visual information benefits audio processing tasks such as speech recognition, there is currently no fully released dataset that can be used for benchmarking multi-modal speaker diarization performance in real-world environments. In this pa-per, we release MSDWild ∗ , a benchmark dataset for multimodal speaker diarization in the wild. The dataset is collected from public videos, covering rich real-world scenarios and languages. All video clips are naturally shot videos without over-editing such as lens switching. Audio and video are both released. In particular, MSDWild has a large portion of the naturally overlapped speech, forming an excellent testbed for cocktail-party problem research. Furthermore, we also conduct baseline experiments on the dataset using audio-only, visual-only, and audio-visual speaker diarization.
