Yu is associated with 1 patent, titled “Voice Based Activation Detection.” The computer-implemented method determines whether a user’s initial utterances contain predetermined wake-up words and, when they do, starts an interaction with a voice assistant. If the user pauses for a specified period and then speaks again, the system assesses whether the additional utterances have an agitated tone. When they do not, the system processes them and, if that processing leads to an action, labels the initial utterances as genuine dialog initiation entries.
