Voice based activation detection

Abstract

A computer-implemented method, according to one approach, includes: determining whether initial utterances received from a user include predetermined wake-up words. In response to determining that the initial utterances include the predetermined wake-up words, a voice assistant initiates an interaction with the user. In response to determining that the initial utterances in the audio signal stop for a predetermined period following the initial utterances that include the wake-up words, determining whether additional utterances are received from the user. In response to receiving additional utterances from the user, determining whether the additional utterances have an agitated tone. In situations where the additional utterances do not have an agitated tone, the additional utterances are processed. Furthermore, in response to determining that causing the additional utterances to be processed results in action being taken, the initial utterances are labeled as genuine dialog initiation entries.
