Interruptibility
Guide to EVI's interruptibility feature and how to manage interruptions on the client.
Interruptibility is a core feature of EVI that enables natural, real-time interaction. Users can speak over the assistant at any time. When they do, EVI detects the interruption, stops generating the response, and immediately notifies the client.
