Abstract
Providing contextual help in an interactive voice system includes receiving a plurality of user interaction events during a user interaction window, wherein each of the user interaction events comprises one of a low quality voice transcription event from a speech-to-text (STT) service or a no-intent matching event from a natural language processing (NLP) service and receiving a respective transcription confidence score from the STT service for each of the plurality of user interaction events. For a one of the plurality of user interaction events, a determination is made of how to respond to a user providing the user interaction events based on how many events comprise the plurality of events and the transcription confidence score for the one event; and then instructions are provided to cause the determined response to be presented to the user in accordance with the determination of how to respond.
