The paper presents a new wake‑up system for voice assistants that goes beyond simple keyword spotting by adding contextual trigger detection. After the wake word is heard, the system reasons to differentiate between actual user commands and unrelated speech, enabling more efficient and context‑aware interactions. A data‑generation architecture is introduced that creates a 62.3‑hour corpus of controllable multi‑speaker conversations, including direct invocations, contextual follow‑ups, and non‑addressed speech, and experimental results confirm the approach’s effectiveness across varied synthetic scenarios.

Recent advancements in Large Language Models (LLMs) have empowered home assistants with natural language interaction capabilities. However, current assistants overlook the progressive omission that occurs in human dialogue as shared context accumulates, leading to more elliptical expressions for efficient communication.

Conversation Coach is a voice‑first AI system that lets managers rehearse difficult workplace conversations in a realistic spoken format. It tackles low‑latency interaction, adaptive bot personalities that simulate various employee types, and personalized feedback on content and policy compliance. The authors compare an end‑to‑end speech‑to‑speech model with a cascaded approach, finding the former offers lower latency and cost, while the cascaded model provides better reasoning for coaching quality, and they deployed the cascaded architecture to 40,000+ managers over six months.
