Answer: Azure Custom Vision
To analyze videos and detect specific objects and activities, you should use Azure Custom Vision. This service allows you to train a custom model using your labeled dataset, which can then be used to analyze new videos and detect the desired objects and activities. While Azure AI Video Indexer and Azure AI Vision Spatial Analysis can also analyze videos, they do not provide the flexibility to train custom models for specific tasks. Azure Cognitive Services Speech Service is focused on speech recognition and is not suitable for object and activity detection.
