Remarks

A SpeechEventsActivity works closely with a SpeechSequenceActivity, which defines a main flow. A SpeechEventsActivity represents the system-initiated events and triggers (and their processing) that can occur while the main flow is in progress.

Each SpeechEventActivity in this collection represents an event or trigger that can occur, as well as the handler for the event. A SpeechEventsActivity acts as a subscriber for these events by obtaining subscription data from each SpeechEventActivity in the collection. A SpeechEventsActivity also receives events as they occur and executes the associated speech events.
