This standard adopts MPAI Technical Specification Version 2 as an IEEE Standard. Multimodal Conversation (MPAI-MMC) specifies use cases, all of which share the use of artificial intelligence (AI) to enable a complete and intense form of human-machine conversation.

Multimodal Conversation (MPAI-MMC) specifies: 1. Data Formats for analysis of text, speech, and other non-verbal components as used in human-machine and machine-machine conversation applications. 2. Use Cases implemented in the AI Framework using Data Formats from MPAI-MMC and other MPAI standards and providing recognized applications in the Multimodal Conversation domain. This Technical Specification includes the following Use Cases: 1. Conversation with Personal Status (CPS), enabling conversation and question answering with a machine able to extract the inner state of the entity it is conversing with and showing itself as a speaking digital human able to express a Personal Status. By adding or removing minor components to this general Use Case, five Use Cases are spawned: 2.Conversation About a Scene (CAS) where a human converses with a machine pointing at the objects scattered in a room and displaying Personal Status in their speech, face, and gestures while the machine responds di...
