Title: Gui Lei Yang and Voice-Based Activation Detection.

Introduction. Gui Lei Yang is an inventor based in Beijing, China. His patent work includes a voice-based activation detection method developed in connection with International Business Machines Corporation. The available information identifies 1 patent associated with him.

Latest Patents. Yang’s patent, “Voice Based Activation Detection,” describes a computer-implemented method for distinguishing genuine voice-assistant interactions from other speech. The system first checks whether a user’s initial utterances contain predetermined wake-up words. If they do, the voice assistant begins an interaction. After a pause of a specified duration, the system checks for additional utterances and assesses whether they have an agitated tone. When the additional speech is not agitated, it is processed; if that processing leads to an action, the initial utterances are labeled as genuine dialog initiation entries.

Career Highlights. The available information connects Yang’s patent work with International Business Machines Corporation. The invention focuses on voice-assistant activation and on evaluating speech context to help determine whether a user intends to initiate a genuine interaction.

Collaborations. Cheng Yun Yu and Yuan Jie Zhang are identified as Yang’s coworkers. The provided information does not specify their roles in the patent or the extent of their collaboration.

Conclusion. Gui Lei Yang’s documented patent work addresses a practical challenge in voice-assistant design: identifying genuine user interactions by considering wake-up words, pauses, and the tone of subsequent speech.
