Abstract: Provided is a voice assistance system with proactive routines that couples a remote server and respective user voice interactive devices to deliver a complete experience to the end user of the device. The user devices can be managed by groups and/or associated entities who manage voice services for their users. For example, the entities can provide pre-configured voice routines that perform actions on behalf of their users. The voice assistance system can also allow users to customize these routines to improve day to day operation. In addition, external services and/or providers can be linked to the system and allowed to define routines that have external system dependencies. Avoiding and managing conflicts in this environment becomes quite challenging. Some approaches use execution queues and priority, others invoke time slices and limitations on assignment of routines to time slices to resolve these issues, among other examples.
